One-Bowl Browned Butter & Raspberry Financier Slab

Instructions

1. 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.

2. 2

   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.

3. 3

   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.

4. 4

   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. 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. 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.

   Tip: Financiers are best eaten the day they are made, ideally with a strong espresso.
