Sunshine-on-the-Windowpane Olive Oil Cake with Cara Cara, Cardamom & Honeyed Kumquat Confetti
January is when I bake for light. This olive oil cake is my “sunshine-on-the-windowpane” move: clean citrus, tender crumb, crisp edges—café-level without the drama. Cara Cara orange zest goes straight into the batter, cardamom rides shotgun, and the whole thing stays plush for days.
The inspiration is half Paris, half Bay Area winter. In Paris, we didn’t do overly sweet desserts; we did restraint, perfume, and texture. In California, citrus is a mood. The first time I made a version of this, it was a gray Tuesday with a too-quiet kitchen. I zested one orange, and the room immediately smelled like optimism. Let time do the work.
The shortcut is olive oil + a whisk. No creaming butter, no mixer, no waiting for anything to “fluff.” Why it works: olive oil coats flour differently than butter, so the crumb stays moist longer.
Don’t skip this: preheat properly (a timid oven gives you a tight crumb—tight like a bad alibi), and finish with flaky salt. Butter is not a garnish, but salt is the mic drop.
Make it yours: swap cardamom for fennel pollen, use blood orange, or add a spoon of crème fraîche for extra tang. Cami’s shortcut note: candy the kumquats in honey for 5 minutes—confetti, not jam.

Sunshine-on-the-Windowpane Olive Oil Cake with Cara Cara, Cardamom & Honeyed Kumquat Confetti
This is my January cake: bright, clean citrus flavor in a tender crumb that stays plush for days, with crisp edges that feel café-perfect. I fold Cara Cara orange zest into an olive-oil batter (no mixer drama), then finish with quick honeyed kumquat “confetti” and a blizzard of flaky salt. Not too sweet, very fragrant, and exactly the kind of bake that makes a gray afternoon behave.

Ingredients
- 180 g Granulated sugar(Reserve 1 tsp for macerating the citrus if desired)
- 4 g Fine sea salt(Plus flaky salt to finish)
- 8 g Baking powder
- 1 g Baking soda(A small pinch; helps browning and lift)
- 1 tsp Ground cardamom(Freshly ground if you can)
- 210 g All-purpose flour
- 120 g Extra-virgin olive oil(Choose fruity, not bitter)
- 120 g Whole milk(Or 90 g milk + 30 g yogurt for extra tenderness)
- 2 Eggs(Large, room temp)
- 1 tsp Vanilla bean paste(Or 1 tsp extract)
- 2 Cara Cara oranges(Zest both; juice 1 (about 60 g))
- 120 g Kumquats(Thinly sliced, seeds removed)
- 45 g Honey(For the kumquat confetti)
- 30 g Water(For the kumquat confetti)
- 10 g Lemon juice(Brightens the confetti; about 2 tsp)
- 1 pinch Flaky sea salt(To finish (non-negotiable))
Instructions
- 1
Heat the oven to 175°C / 350°F. Grease and line an 8-inch (20 cm) round pan with parchment. Put the pan on a sheet pan (insurance against drips and uneven heat).
10 min
Tip: Preheat like you mean it. A timid oven makes tight crumb and pale edges.
- 2
Make the honeyed kumquat confetti: add 120 g Kumquats, sliced, 45 g Honey, 30 g Water, and 10 g Lemon juice to a small saucepan. Bring to a gentle simmer, then cook 6–8 minutes until glossy and slightly softened but not collapsed. Cool to room temp.
12 min
Tip: You want jammy sheen, not marmalade. Overcooking turns the peel chewy.
- 3
In a large bowl, whisk 180 g Granulated sugar, 4 g Fine sea salt, 8 g Baking powder, 1 g Baking soda, and 1 tsp Ground cardamom. Add 210 g All-purpose flour and whisk again to evenly distribute the leaveners.
3 min
Tip: This is my shortcut that’s safe: whisking leaveners into the dry ingredients is your “sift,” minus the fuss.
- 4
In a second bowl (or a large measuring jug), whisk 120 g Extra-virgin olive oil, 120 g Whole milk, 2 Eggs, 1 tsp Vanilla bean paste, 2 Cara Cara oranges, zested, and 2 Cara Cara oranges, juiced until smooth and emulsified.
2 min
Tip: If it looks split, keep whisking 15 seconds. Emulsion = tender crumb.
- 5
Pour wet into dry. Fold with a spatula just until no dry flour remains. The batter should be smooth and pourable, like thick ribbon.
2 min
Tip: Non-negotiable: don’t overmix. Overmixing makes the crumb tight like a bad alibi.
- 6
Scrape into the prepared pan. Tap the pan once on the counter to pop big bubbles. Bake 35–42 minutes, until deep golden at the edges and a skewer comes out with a few moist crumbs (not wet batter).
40 min
Tip: Color is flavor. If it’s pale, it’ll taste flat.
- 7
Cool 15 minutes in the pan, then unmold and cool completely on a rack.
20 min
Tip: If you cut it hot, you’ll compress the crumb. Let it set.
- 8
Spoon the cooled honeyed kumquat confetti over the top. Finish with 1 pinch Flaky sea salt. Slice and serve.
3 min
Tip: Salt isn’t decoration here—it sharpens the citrus and makes the olive oil taste expensive.
Chef's Notes
Schedule Snapshot: simmer confetti 10 min (can be done 2 days ahead) • mix 10 min • bake ~40 min • cool 45 min. Why it works: olive oil keeps the crumb plush for days, and citrus juice plus zest give a clean, high-note perfume that tastes like January sun. The kumquat topping brings bitter-sweet complexity—grown-up, not candy. Cami’s shortcut note: no mixer, no syrup soak, no fussy frosting. The confetti does the “wow” with one small pot. Don’t skip this: (1) real preheat, (2) flaky salt finish, (3) zest both oranges—zest is the perfume, juice is the volume. Storage: covered at room temp 2 days, then fridge up to 5 days. Bring slices to room temp before serving for the softest crumb.
Camille Roux
Café-level bakes, weeknight methods, zero compromise.
Camille “Cami” Roux was born in Paris with flour in her hair and a healthy skepticism of culinary dogma. She grew up around neighborhood boulangeries that treated crust and crumb like religion—but what stuck with her wasn’t rigid tradition. It was the quiet precision: good butter that actually tastes like milk, patient fermentation that builds flavor for free, and desserts that know when to stop before they get cloying. After moving to the Bay Area, Cami trained in a bread-and-pastry scene obsessed with texture, naturally leavened doughs, and seasonal fruit—Tartine energy, minus the martyrdom. She became known for loaves that sing when they cool, jammy tarts with clean edges, and “how is this so good?” weeknight pastries made with a few smart shortcuts. Her motto is high impact, low fuss: splurge where it counts (butter, salt, time), streamline the rest (sheet pans, one bowl, cold-proofing). If it doesn’t improve flavor or structure, it doesn’t earn a step.
