One-Bowl Browned Butter & Raspberry Financier Slab
Growing up in Paris, my after-school snack was always a classic financier: deeply nutty, chewy-edged, and aggressively buttery. But making them at home used to mean piping batter into fussy, tiny molds. We're not suffering for brunch. I wanted that lacy, caramelized crust-to-crumb ratio without the headache.The solution? A sheet-pan slab. You get all the chewy edges, none of the piping. The heavy lifting here is done by beurre noisette (brown butter). We simply toast the milk solids until they smell like hazelnuts, giving the crumb a rich depth that anchors the tart pop of fresh seasonal raspberries. Just melt, whisk, and pour into one bowl.Make it your own by swapping the raspberries for sliced local plums or bittersweet chocolate chunks depending on the season. The fridge is your friend here; resting the batter overnight hydrates the almond flour for a denser, richer bite.Cami's shortcut note: You can skip the mixer, but don't skip the rest. Let time do the work. Butter is not a garnish. Bake until the center has a slight jiggle but the edges turn a deep, confident gold. If the crumb is tight like a bad alibi, your almond flour was too old.

One-Bowl Browned Butter & Raspberry Financier Slab
Financiers are the unsung heroes of the Paris pastry case: deeply nutty, chewy-edged, and aggressively buttery. By baking this quick batter as a single sheet-pan slab, we maximize that caramelized crust-to-crumb ratio without messing with tiny molds or piping bags. Browned butter and tart raspberries do all the heavy lifting for your Sunday morning.

Timeline
Ingredients
- 1/2 cup unsalted cultured butter(1 stick, plus extra for greasing if needed. Cut into cubes.)
- 1 cup almond flour(Fine-ground blanched almond flour)
- 1 1/4 cups powdered sugar(Sifted if exceptionally clumpy)
- 1/3 cup all-purpose flour(Spoon and level method)
- 1/2 tsp kosher salt(Diamond Crystal preferred)
- 4 large egg whites(From about 4 large eggs. Carton whites work perfectly here.)
- 1 tsp vanilla extract(High quality)
- 1 1/2 cups fresh raspberries(Washed and thoroughly dried)
- 1/4 cup sliced almonds(Raw, not pre-toasted)
Instructions
- 1
Preheat your oven to 375°F (190°C). Line an 8x8-inch metal baking pan with parchment paper, leaving an overhang on two sides to act as a sling. Cami's shortcut note: Crumple the parchment into a ball first, then smooth it out—it stays put in the corners and won't fight you.
5 min
Tip: Metal pans conduct heat better than glass or ceramic, giving you the chewy, caramelized edges that are non-negotiable for a financier.

Melt 1/2 cup unsalted cultured butter in a light-colored or stainless steel skillet over medium heat. It will melt, foam, and then bubble violently. Swirl the pan constantly. When the popping subsides and the milk solids drop to the bottom and turn the color of dark espresso grounds, pull it off the heat immediately. It should smell intensely like toasted hazelnuts (this is your beurre noisette). Pour it into a heatproof measuring cup to stop the cooking, making sure to scrape in all those dark, flavorful flecks.
6 min
Tip: Don't walk away. Butter goes from browned to burnt in about ten seconds.

In a large mixing bowl, whisk together 1 cup almond flour, 1 1/4 cups powdered sugar, 1/3 cup all-purpose flour, and 1/2 tsp kosher salt. Pour in 4 large egg whites and 1 tsp vanilla extract. Whisk vigorously until you have a thick, paste-like batter. We are not whipping air into the whites here; we just want them fully incorporated into the dry ingredients.
4 min
Tip: Using powdered sugar instead of granulated is why it works: it dissolves instantly into the cold egg whites and yields a dense, velvety crumb.

Gradually stream the warm browned butter into the batter, whisking continuously until smooth, glossy, and emulsified. Scrape the batter into your prepared pan, spreading it flat to the edges. Drop 1 1/2 cups fresh raspberries evenly across the surface. Don't press them in; they'll sink naturally as the batter rises around them. Scatter 1/4 cup sliced almonds into the empty spaces between the berries.
5 min
Tip: The batter will look split for a second when you add the butter—just keep whisking. It will come together.
- 5
Bake for 30 to 35 minutes. You're looking for deeply browned, craggy edges that pull away slightly from the sides of the pan. The center should spring back to a light touch. A pale financier is a sad financier; let the edges get dark. We're not suffering for brunch.
35 min
Tip: If your almonds are browning too quickly at the 20-minute mark, tent the pan loosely with foil.
- 6
Transfer the pan to a wire rack. Let time do the work: cool for at least 15 minutes before using the parchment sling to lift the slab out. Slice into 9 squares. The crumb will be tight like a bad alibi if you cut it piping hot, so wait until it's just warm or room temperature.
15 min
Tip: Financiers are best eaten the day they are made, ideally with a strong espresso.
Chef's Notes
Butter is not a garnish. Use European-style cultured butter here—it has a higher fat content and tangier profile that balances the sweet almond flour perfectly. If you only have standard butter, it will still work, but cultured butter makes it café-level. Also, if you bake this on a weeknight, it keeps beautifully in an airtight container for up to two days, though the edges will soften slightly.

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.
