Vienna's cafés bake this in the papal colors, white and gold, which is the whole name: the cardinal's slice. Two batters share one oven, piped in alternating ribbons so the meringue dries ivory while the sponge bakes gold, and the striping is done before the bake instead of after. The recipe came into the book from a classic Austrian source and needed exactly one conversion, the cream, to sit at this table. It is café food in the best sense: formal to look at, soft to eat, and made to be lingered over with strong coffee.

The Tools

Stand mixer or hand mixer with two bowls · Meringue whips first in the clean bowl; the yolk mass can follow in the same bowl unwashed, never the reverse
Two sheet pans
Parchment paper + pencil and ruler · The stripe geometry gets drawn, then the parchment flips. Freehand stripes wander
Two piping bags with 1.5cm plain round tips · One per batter. A cut freezer bag works at the cost of wobblier ribbons
Medium saucepan (the pudding)
Whisk
Rubber spatula
Fine-mesh sieve or sifter
Offset spatula
Clean kitchen towel (the inversion)
Kitchen scale · Two batters, one oven: the ratios are the recipe
Serrated knife

✚ ends up in the sink · essentials unless marked optional

The Two Masses

Yields Two striped sheets, 12 x 30cm each

Why this works One egg, divided against itself: the whites become a cornstarch-stabilized meringue that must dry pale, and the yolks (with two whole eggs for backbone) become a ribboned sponge that must bake gold. The cornstarch in the meringue binds free water so the ribbons dry crisp-edged and marshmallow-hearted instead of weeping. The bake is a deliberate bait-and-switch: the oven preheats to 400°F so the sponge gets the hot spring it needs the moment it lands, then drops immediately to 325°F so the meringue spends the rest of the half hour drying instead of browning. Hold it at 400 and the meringue tans; the white-and-gold contrast, the dish's entire name, goes beige. The piping geometry is exact because the slice is the presentation: get the strips straight and touching and every cut shows clean cardinal stripes.

5 large (165g), room temperature Egg whites · Not a speck of yolk in them, or they will not whip
100g (1/2 cup) Granulated sugar 100 g
8g (1 packet) Vanilla sugar 8 g · Or 8g sugar rubbed with the seeds scraped from 2cm of vanilla bean
40g (1/3 cup) Cornstarch (for the meringue) 40 g · Folded in last; it binds water so the ribbons dry instead of weeping
2 large eggs + 3 large yolks, room temperature Whole eggs + yolks · The whites left over from the meringue's yolks close the loop: this recipe uses five whole eggs, cleanly split
60g (1/2 cup), sifted Icing sugar (for the yolk mass) 60 g
60g (1/2 cup), sifted All-purpose flour 60 g

Draw the geometry 8 min hands-on

On two parchment sheets, rule a 12 x 30cm rectangle each, then divide it lengthwise into five strips: three 2.5cm-wide meringue lanes at the edges and center, two 2cm sponge lanes between them. Flip the parchment ink-down onto the pans. Fit both piping bags with their tips. Oven to 400°F (200°C).
The white mass 8 min hands-on

Whip the whites on medium to soft peaks, then rain in the granulated and vanilla sugar a spoonful at a time on high. Whip to stiff and glossy, then fold in the cornstarch with the spatula in as few strokes as it takes.

Look for Peaks that stand with the barest bend at the tip, glossy as wet paint; rub a pinch between fingers and no sugar grit remains.

Take care Underwhipped meringue spreads and the stripes blur into each other in the oven. If the peak flops over, keep whipping before any cornstarch goes in.
The gold mass 8 min hands-on

In the second bowl (or the same one, unwashed), whip the whole eggs, yolks, and icing sugar on high 4-5 minutes to a thick ribbon. Sift the flour over in two additions, folding with wide bottom-scraping strokes until no dry streaks remain.

Look for Pale gold and tripled; the beater draws a ribbon that rests on the surface a full 3 seconds before sinking.

Take care This foam is the sponge's only lift. Fold past no-streaks and the strips bake flat and dense next to the meringue's height.
Pipe the stripes 12 min hands-on

Meringue into one bag, gold mass into the other. On each sheet, pipe the three meringue ribbons down their lanes first, thumb-thick and steady, then pipe the gold mass into the two gaps between them, a shade lower than the white.

Look for Five parallel ribbons, touching but distinct: white, gold, white, gold, white. Height in the meringue, restraint in the gold.

Take care The gold mass loses air by the minute, so pipe and bake without pausing to admire. Batter that waits on the counter bakes into flat tan lines.
Bake on the drop 2 min hands-on · 30 min wait

Both pans into the 400°F oven, upper and lower thirds, and immediately turn it down to 325°F (160°C). Bake about 30 minutes, swapping the pans top to bottom at 20.

Look for Meringue dry to a light fingertip touch and still ivory; sponge strips gold and springy. If the white is taking color, the oven runs hot: drop it 15 degrees and finish.

Take care Skip the temperature drop and the meringue tans in the first ten minutes. The contrast is the dish; there is no dusting it back to white.
Sugar, invert, peel 5 min hands-on · 40 min wait

Dust each baked sheet with icing sugar, lay the clean towel over, invert pan and all, lift the pan away, and peel the parchment back while the sheets are still warm. Cool completely on the towel, stripes down.

Look for Parchment peels back in one slow sheet, taking nothing with it.

Take care Cold parchment welds to meringue and tears the ribbons off in patches. Peel warm, low and slow, pulling the paper back against itself rather than up.

When it goes wrong

Problem	Cause	Fix
Meringue browned instead of staying ivory	Oven never dropped to 325°F, or runs hot uncalibrated	Turn it down the moment the pans go in and trust the longer dry; an oven thermometer settles the argument with your dial once and for all
Stripes spread and merged into one sheet	Meringue underwhipped or the gold mass deflated before piping	Stiff glossy peaks before the starch, and pipe the moment both masses are ready. Merged stripes still taste right; slice it anyway and call the next one practice
Meringue weeping beads of syrup after cooling	Sugar added too fast, or humid day	Rain the sugar in a spoonful at a time next round; today, blot gently and assemble anyway, the cream hides a quiet tear or two

Vanilla Pudding Cream

Yields ~700g cream, a generous layer Make 0-1 days ahead

Why this works This is German buttercream by way of a Viennese pastry case: a cornstarch pudding beaten spoonful by spoonful into whipped butter and icing sugar, landing lighter than pastry cream and sturdier than whipped cream. The pareve build changes ingredients, not logic. Full-fat oat milk brings its own gentle grain sweetness to the pudding, and a cultured plant stick brings the lactic tang cultured butter would; beaten hard, it goes paler and lighter than its dairy cousin. The single law of this cream is temperature: pudding and butter must both stand at cool room temperature when they meet. Cold pudding into soft butter seizes the fat into curds; warm pudding melts it into soup. Match them and they emulsify into a mousse that holds a piped edge. The Viennese pour this slice two ways, vanilla or coffee; if your table drinks espresso, dissolving 2 teaspoons of instant espresso into the hot pudding is the honest second road, not a garnish.

400ml (1 2/3 cups) Full-fat oat milk 400 g · Full-fat and unsweetened; its body is doing whole milk's work in the pudding
40g (1/3 cup) Cornstarch 40 g
1, split and scraped Vanilla bean · Or 2 tsp extract stirred in off the heat; the bean gives the cream its freckles
150g (1 1/4 cups), sifted Icing sugar 150 g
100g (7 tbsp), soft Cultured plant butter, stick-style 100 g · Cool room temperature: pliable, holds a fingerprint, no shine. Tub spreads carry water and will not build this cream
1 pinch Fine sea salt

Cook the pudding 8 min hands-on

Whisk the cornstarch smooth into 100ml of the cold oat milk. Bring the rest to a simmer with the vanilla bean and seeds, pull the pod, then whisk in the slurry and boil, whisking constantly, a full 60-90 seconds.

Look for Thick enough that the whisk leaves trails, with slow heavy bubbles breaking the surface. Taste a cooled dab from the spoon: silky, no chalk.

Take care Cornstarch that never fully boils stays chalky and loose, and a loose pudding makes a cream that slumps off the slice. Give it the full boil.
Cool to the meeting point 2 min hands-on · 1 h wait

Scrape the pudding into a shallow bowl, press film onto its surface, and cool on the counter to cool room temperature, about an hour. Set the butter out beside it so they arrive together.

Look for Bowl and butter both neutral to the back of a finger: not warm, not fridge-cold. That match is the whole step.

Take care The fridge is the trap here. Fridge-cold pudding hitting soft butter curdles the cream on contact; this cool-down happens on the counter.
Beat the cream 8 min hands-on

Whip the soft butter, icing sugar, and salt on high 3-4 minutes until pale and fluffy, then beat in the pudding one spoonful at a time, letting each vanish before the next.

Look for A pale, glossy mousse that holds a soft peak off the beater and a clean edge off the spatula.

Take care If it turns grainy and curdled, the temperatures missed: set the bowl over barely warm water for 30 seconds, then beat hard and it comes back together. Do not keep adding pudding to a split cream.

When it goes wrong

Problem	Cause	Fix
Cream split into curds and liquid	Pudding and butter met at different temperatures	Thirty seconds over barely warm water, then beat on high until it snaps back glossy. Prevention is the counter cool-down, not the fridge
Cream loose, will not hold a layer	Pudding underboiled, or tub-style spread instead of a stick	Chill the finished cream 20 minutes and re-whip; it firms as the fat cools. Next round, the full boil and a stick-style butter
Tastes of raw starch	The 60-90 second boil got cut short	No fix once built; taste the pudding at step 1, where 30 more seconds of boiling still saves it

Build & Chill

Yields 10 slices Make 0-1 days ahead

Why this works Assembly is one decision and one hour of patience. The homelier sheet goes stripes-down as the base, the cream goes on in an even inch, and the handsomer sheet lands stripes-up. Then the chill: an hour in the fridge sets the cream and lets the meringue's edges soften against it, so the knife meets one texture instead of three. Sliced sooner, it shatters and squeezes; sliced later, still lovely. The icing-sugar dusting waits for the plate, because sugar on chilling meringue slowly dissolves into gloss.

2 tbsp, for dusting at the plate Icing sugar (to finish) · Dust at service, not before the chill

Sandwich 6 min hands-on

Lay the less handsome sheet stripes-down on the serving board. Spread or pipe all the cream to an even layer, holding back a finger's width at the long edges. Set the second sheet on top, stripes up, and press with flat hands, gently and evenly, until cream meets the edges.

Look for Cream in one level seam, peeking at the sides without bulging over.

Take care Press at the center only and the cream surges out the ends while the middle hollows. Flat hands, whole surface, light touch: the meringue underneath is crushable.
The hour 1 min hands-on · 1 h wait

Refrigerate the built slice, uncovered, 1 hour minimum. This chill is structural, not storage: it sets the cream for the knife.

Look for A fingertip at a corner of the top sheet meets gentle resistance instead of slide.

When it goes wrong

Problem	Cause	Fix
Slices smear and squeeze cream out under the knife	Chill skipped or cut short	Back into the fridge for the full hour; the cream firms and the knife starts cutting instead of pushing
Top sheet cracked during the press	Uneven pressure on a crisp meringue	Cosmetic, not fatal: the dusting and the cream hold it together, and the stripes still read in the slice
Gone soft and sticky by day two	Meringue drawing moisture from the cream over time	That is the clock, not a mistake. This dessert peaks between hour one and hour twelve; bake the sheets the day you mean to serve it

To the Table

Slice cold with the serrated knife, wiped clean between cuts: gentle strokes across the stripes, so every piece shows white, gold, white over its seam of cream.
One slice per plate, stripes running toward the guest, and dust icing sugar over at the last minute.
Pour strong coffee alongside; in Vienna this slice does not appear without it.
Serve within the day. Hour one to hour twelve is its whole prime, and the table should know they caught it.

Numbers are per slice, ten to the bake. Most of the carbs are the three sugars doing structural work across the meringue, the sponge, and the cream; the fat is nearly all the cream's beaten butter. Airy to eat and richer than it looks, which is very Viennese of it.

Words We Used

Kardinalschnitte: The 'cardinal's slice': a Viennese café classic striped white and gold, the cardinal colors, from meringue and yolk sponge baked side by side and sandwiched around cream.
German buttercream: Cream built by beating cooked pudding into whipped butter. Lighter than American buttercream, sturdier than whipped cream, and entirely dependent on both halves meeting at the same cool room temperature.
Ribbon stage: Eggs and sugar whipped until the falling batter rests on the surface a few seconds before sinking: the foam that gives the gold stripes their entire lift.
Vanilla sugar: Sugar perfumed with vanilla, sold in packets across Austria and Germany. Homemade in thirty seconds: rub sugar with scraped vanilla seeds until fragrant.
