Double-Baked Orange Blossom Bostock
Growing up in Paris, bostock was the baker's brilliant answer to yesterday's unsold brioche. I used to buy a slice on my walk home from school, the almond crust shattering onto the sidewalk. Now, it's my ultimate weekend flex.
Bostock looks like three days of stressful lamination, but it's just stale brioche living its best second life. We soak thick-cut bread in a quick orange-blossom syrup, bury it under a rapid one-bowl frangipane, and bake it until the almond cream puffs. Café-level breakfast, zero dough-folding required. We're not suffering for brunch.
The magic is in the soak. A dry crumb is tight like a bad alibi. The syrup ensures the center stays pudding-soft while the frangipane caramelizes on top.
Make it your own: swap the orange blossom for dark rum, or fold toasted pistachios into the frangipane.
Cami's shortcut note: Buy a good cultured-butter brioche loaf. Let time do the work by slicing it thick and leaving it on the counter overnight to dry out.
Don't skip this: Watch the edges in the oven. You want a confident golden brown. When the center wobbles slightly but the edges are set, pull it.

Timeline
Ingredients
- 1/3 cup water(For the syrup)
- 1/2 cup granulated sugar(Divided (1/4 cup for syrup, 1/4 cup for frangipane))
- 1 orange(Zested)
- 1 tsp orange blossom water(Can substitute with vanilla extract)
- 4 tbsp cultured butter(Softened to room temperature)
- 1 large egg(Room temperature)
- 1/2 cup almond flour(Finely ground)
- 1/4 tsp kosher salt(Diamond Crystal)
- 1/2 tsp almond extract
- 4 thick-cut slices day-old brioche(Cut at least 1-inch thick, left out overnight to dry)
- 1/2 cup sliced almonds
- 1 tbsp powdered sugar(For dusting)
- 1 orange zest of 1 orange(zest)
Instructions
- 1
Preheat oven to 375°F (190°C). In a small saucepan, combine 1/3 cup water, 1/4 cup granulated sugar, and the zest of 1 orange. Bring to a simmer over medium heat until the sugar completely dissolves. Pull it off the heat and stir in 1 tsp orange blossom water. Let it cool slightly.
5 min
Tip: If you don't have orange blossom water, vanilla extract or a splash of Grand Marnier works brilliantly. The goal is an aromatic soaking liquid.

While the syrup cools, build the quick frangipane. In a medium bowl, aggressively mash 4 tbsp cultured butter and the remaining 1/4 cup granulated sugar with a flexible spatula until it forms a thick paste. Vigorously beat in 1 large egg, 1/2 cup almond flour, 1/4 tsp kosher salt, and 1/2 tsp almond extract. You want a smooth, spreadable cream. No stand mixer needed—we're not suffering for brunch.
5 min
Tip: If your butter is too cold, the mixture will separate. Just power through and keep mixing; the almond flour will eventually bind it.
- 3
Arrange your 4 thick-cut slices day-old brioche on a parchment-lined sheet pan. Generously brush the tops with the warm orange blossom syrup. Don’t be shy—the bread should drink it up like a sponge. This double-baking technique is exactly why we use stale bread; a fresh slice would just turn to mush.
2 min
Tip: Make sure to brush the syrup all the way to the crusts so they don't burn during the second bake.
- 4
Smear the frangipane evenly over the soaked brioche slices, taking it right to the edges to seal in the moisture. Press 1/2 cup sliced almonds firmly into the frangipane layer so they anchor during the bake.
3 min
Tip: Going edge-to-edge with the frangipane protects the brioche from scorching and creates a beautiful crust-to-crumb ratio.
- 5
Bake for 15 to 18 minutes. You are looking for the frangipane to puff up and turn a deep, confident golden brown, while the almonds toast to a crisp finish.
15 min
Tip: Watch the almonds around the 12-minute mark. If they are browning too aggressively, tent loosely with foil.
- 6
Let the bostock cool on the pan for 5 minutes. The center will settle into a warm, custardy dream while the edges shatter. Dust lightly with 1 tbsp powdered sugar and serve immediately.
5 min
Tip: Do not skip the resting time. The frangipane needs a few minutes to set up so it doesn't run when you bite into it.
Chef's Notes
Cami’s shortcut note: The frangipane can sit in an airtight container in the fridge for up to a week. Make it on a Sunday, and you're literally three minutes of prep away from a hot café-level pastry on a Wednesday morning. Butter is not a garnish here—use the cultured stuff for that necessary tang to offset the sweet almond. Don't skip the stale bread step; we need that structure to carry the syrup without collapsing.
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.
