Lemon-Soufflé Pudding Cake
This amazing soufflé from Måurice Luncheonette is cakey on top, puddingy on the bottom, tart all the way through.
From: bonappetit.com SERVES 8
4 tablespoons (½ stick) unsalted butter, room temperature, plus more for baking dish
¾ cup granulated sugar, plus more for baking dish
1 cup buttermilk
½ cup crème fraîche or sour cream
2 teaspoons finely grated lemon zest
½ cup fresh lemon juice
3 large eggs, separated
1/3 cup all-purpose flour
¼ teaspoon kosher salt
Powdered sugar (for serving)
Fresh blackberries (for serving; optional)
Preheat oven to 325°. Butter a shallow 1½–2-qt. baking dish, then sprinkle with granulated sugar. Stir buttermilk, crème fraîche, lemon zest, and lemon juice in a medium bowl just to combine and set aside.
Using an electric mixer on high speed, beat 4 Tbsp. butter and ¾ cup granulated sugar in a large bowl until well combined, about 4 minutes. Add egg yolks 1 at a time, beating to blend between additions and scraping down sides of bowl as needed.
Reduce mixer speed to low and, with motor running, add reserved buttermilk mixture in 3 additions, alternating with flour in 2 additions, beginning and ending with buttermilk mixture (batter will be extremely loose).
Using an electric mixer with clean, dry beaters, beat egg whites and salt on high speed in a medium bowl until soft peaks form. Fold egg whites into pudding cake batter in 3 additions, just barely blending after each addition.
Scrape pudding cake batter into prepared baking dish and place on a rimmed baking sheet. Bake until top is puffed and golden brown and center barely jiggles, 35–45 minutes. Transfer baking dish to a wire rack and let pudding cake cool at least 30 minutes.
Serve pudding cake dusted with powdered sugar and topped with blackberries, if desired.
Pudding cake can be baked 1 day ahead. Cover and chill. Bring to room temperature before serving.
