Written as the closer for a steak, shrimp, and bravas dinner, when the table needed a reset instead of a second heavyweight. It bakes in the afternoon, waits at room temperature without complaint, and is better on day two — the rare dessert that rewards being ignored.

The Cake
Why this works A single-bowl stirred cake — no creaming, because creaming exists to trap air in solid butter and olive oil is liquid; the baking powder does all the lifting instead. The result is denser and moister than a butter cake, closer to pound cake crossed with sponge, and that's the point. Oil is also why it keeps: butter cakes stale as their fat resolidifies and their starch retrogrades (recrystallizes); liquid oil coats the starch and slows that recrystallization, so the crumb is actually better on day two. Streaming the oil into whisked eggs matters — the yolks' lecithin binds oil and water into a stable emulsion, vinaigrette-style; dumped at once, it pools. Zest carries the lemon's aromatic oils, juice carries its acid; you need both, and they do different jobs. Choose a medium-fruity EVOO — aggressive peppery oils read bitter after baking, and refined 'light' oil defeats the purpose. The oil IS the flavor ceiling here: taste it from a spoon before you commit a cake to it.
- 3 (150g), room temperature Large eggs 150 g — Out of the fridge 30 minutes ahead — cold eggs emulsify poorly
- 200g (1 cup) Granulated sugar 200 g
- 180ml (3/4 cup, 164g) Extra virgin olive oil 164 g — Medium-fruity; not 'light' or 'pure' — those are refined and flavorless
- 2 tbsp, from 2–3 large lemons Fresh lemon zest — Microplane; zest before juicing
- 2 tbsp (30g) Fresh lemon juice 30 g
- 1 tsp Vanilla extract — Pure, not imitation
- 240g (1 3/4 cups + 2 tbsp) All-purpose flour 240 g
- 1 1/2 tsp Baking powder — Check the date — expired powder means a flat cake
- 3/4 tsp Diamond Crystal Kosher salt — Halve if using Morton's
- 80ml (1/3 cup) Warm tap water 80 g — Warm, not hot — thins the batter to its proper pour
-
Prep the pan 4 min hands-on
Oven to 350°F (175°C). Grease the pan, line the bottom with a parchment round, grease the parchment.
Take care Skip the parchment and this tender crumb can stay behind in the pan. The parchment is the insurance. -
Whisk eggs and sugar 2 min hands-on
Eggs and sugar in the large bowl. Whisk hard for about 1 minute — pale, slightly frothy, sugar mostly dissolved. Not ribbon stage; a thin custard base.
Look for Uniform pale yellow with no granules grinding at the bottom of the bowl.
-
Stream in the oil 2 min hands-on
Whisking continuously, pour the oil in a slow, steady stream, then whisk 30 seconds more.
Look for A smooth, slightly thickened golden emulsion — no oil slick on the surface.
Take care Dumped at once, the oil pools instead of emulsifying. Slow stream, moving whisk. -
Citrus and vanilla 5 min hands-on
Zest the lemons, then juice them. Whisk zest, juice, and vanilla into the emulsion. Bring the bowl to your nose: bright lemon over warm olive oil. Quiet lemon means add more zest — the aromatics live there, not in the juice.
-
Whisk the dry 2 min hands-on
Flour, baking powder, and salt whisked together in a second bowl so the leavening is evenly distributed.
-
Fold, then water 3 min hands-on
Dry into wet in two additions, folding gently until barely combined after each. Then fold in the warm water until smooth.
Look for Pourable pale-gold batter flecked with zest — thick pancake consistency, ribbons off the spatula in a steady stream.
Take care Overmixing develops gluten and buys you a tough, chewy cake. The moment no dry streaks remain, put the spatula down — a few small lumps beat a rubbery crumb. -
Bake 40–45 min 2 min hands-on · 43 min wait
Pour into the pan — it self-levels, no spreading needed. 350°F for 40–45 minutes. Don't open the oven before 35. Toothpick in the center: clean or a few moist crumbs is done; wet batter means 3–5 more minutes and retest.
Look for Deep golden top, edges pulling slightly from the pan, center springs back to a light press.
Take care Browning fast on top but wet inside means a hot oven — tent loosely with foil for the last 10 minutes. -
Cool completely 3 min hands-on · 1 h 30 min wait
15 minutes in the pan on the rack. Thin knife around the edge, invert, peel the parchment, flip right-side up. Cool fully — 1 hour minimum, 2 is better.
Take care Glaze a warm cake and the glaze melts, thins, and soaks in instead of setting into a shell. Fully cool or don't glaze.
When it goes wrong
| Problem | Cause | Fix |
|---|---|---|
| Dense, heavy crumb | Overmixed batter or dead baking powder | Fold to barely combined; replace baking powder older than 6 months |
| Sank in the center | Underbaked, or oven opened early | Keep the door shut until 35 minutes; bake to a clean toothpick |
| Bitter olive-oil edge | Aggressively peppery or grassy oil | Use a medium-fruity EVOO; taste the oil from a spoon before it goes in |
Rich Lemon Glaze
Why this works Most lemon glazes are powdered sugar stirred with juice: matte, gritty, thin. This one is heated to 100–110°F, and the heat is the whole trick — undissolved sucrose crystals are what scatter light and read as grit and chalk, and gentle warmth dissolves them completely into a solution that dries glassy and semi-translucent. (Powdered sugar's ~3% cornstarch stays dispersed either way; it's the sugar that must dissolve.) The ceiling is low: boil it and the concentrated syrup recrystallizes as it cools, back to matte and rough. Same approach French pâtisserie uses on éclairs and petits fours. Poured on a fully cooled cake, it pools, flows, and sets in 20–30 minutes into a shell that cracks under the knife.
- 180g (1 1/2 cups), sifted Powdered sugar 180 g — Sift — small lumps become bumps in the finished shell
- 3 tbsp (45g), strained Fresh lemon juice 45 g — No pulp, no seeds — they mar the surface
- 1 tsp Fresh lemon zest — Goes in off the heat; bright flecks in the set glaze
- tiny pinch Kosher salt — Invisible but load-bearing against the sweetness
-
Sift and combine 3 min hands-on
Sift the powdered sugar into the small saucepan. Whisk in the strained lemon juice — paste at first, then a thick, pourable ribbon.
Look for Lifted on the whisk, it falls in a thick ribbon that sits on the surface 2–3 seconds before sinking. Too stiff: juice 1/2 tsp at a time. Watery: sifted sugar 1 tbsp at a time.
-
Warm to 100–110°F 2 min hands-on
Lowest heat, whisking constantly, 60–90 seconds — warm to the touch, every trace of grit dissolved.
Look for The glaze turns noticeably thinner, glossier, and more translucent as the sugar dissolves.
Take care Do not boil. One bubble and off the heat — overheated glaze recrystallizes matte and rough as it cools, and there's no fixing it. -
Zest and salt 1 min hands-on
Off heat, stir in the zest and salt.
-
Pour once, guide once 3 min hands-on
Cooled cake on the rack over a sheet pan. Pour the warm glaze onto the center in one steady stream, then guide it to the edges with the back of a spoon and let it run down the sides in thick, uneven rivulets. Don't chase drips.
Look for Top fully coated, sides streaked partway down — the organic, handmade flow is the look.
Take care It starts setting in 2–3 minutes. Rework it after that and you drag matte scars through the gloss. Pour once, guide once, walk away. -
Set 20–30 min 25 min wait
Undisturbed on the rack at room temperature until the surface is smooth and faintly tacky, not sticky.
Look for Semi-translucent shell that catches light like lacquer; it will crack cleanly when sliced — that crack is the payoff, not a flaw.
When it goes wrong
| Problem | Cause | Fix |
|---|---|---|
| Gritty, chalky glaze | Sugar never fully dissolved — unsifted or unheated | Sift first; rewarm gently, whisking, until translucent |
| Matte instead of glossy | Boiled — sugar recrystallized on cooling | Remake with fresh sugar and juice; lowest heat, 100–110°F only |
| Glaze soaked into the cake | Cake was still warm | Unfixable this round and still tastes good; cool completely next time |
To the Table
Slice with a sharp chef's knife, pressing straight down — sawing drags the glaze. Wipe the blade between cuts.
One slice per white plate, angled slightly; the gold crumb and cracked glaze carry the plate.
Finish each slice with 2–3 flakes of Maldon just before it leaves the kitchen.
Optional: a few raspberries or blackberries alongside for color and acid, or a thin thread of the same olive oil across the plate.
At the table, a light pass of fresh zest over the slices — the microplane perfumes the air on the way down. Pairs with espresso.

One glazed slice is a real dessert, not a light one — the glaze roughly doubles the sugar of the crumb. The single-layer format keeps the portion honest.
Words We Used
- Emulsify
- Binding two liquids that resist mixing — here oil into egg — into one stable, uniform mixture, held by the yolks' lecithin.
- Ribbon stage
- When lifted batter falls in a trail that rests on the surface for a few seconds before sinking. This cake stops short of it: pale and frothy is enough.
- Zest
- The colored outer layer of citrus peel, where the aromatic oils live. The bitterness is in the white pith below — don't grate that deep.
- Starch retrogradation
- The recrystallization of starch that makes baked goods stale. Liquid oil slows it, which is why this cake improves on day two.
- Tent
- A loose foil cover over a browning bake — blocks top heat without steaming the crust.
