makes one cake
I made this as a welcome home from Minnesota present for my mom. I wanted it to be small, so I quartered the recipe using my mini cake pans. It turned out great; probably the lightest cake I’ve ever made.
very slightly adapted from www.epicurious.com
- 2 cups sifted cake flour (or 2 cups minus 4 tbsp sifted all-purpose flour)
- 1 tsp baking powder
- 1 tsp baking soda
- 1/2 tsp salt
- 1 stick unsalted butter, softened
- 1 cup sugar
- 1 tsp pure vanilla extract
- 2 large eggs
- 1 cup well-shaken buttermilk (or 1 cup milk plus 1 tbsp white vinegar or greek yogurt or lemon juice)
- 1/2 cup water
- 1/2 cup sugar
- 3 cups mixed berries (blackberries, cut up strawberries, blueberries, raspberries)
- 1 cup mascarpone cheese
- 1 cup chilled heavy cream
- 1/4 cup sugar
- confectioners sugar
Preheat oven to 350°F with rack in middle. Butter a 9-inch round cake pan (2 inches deep). Line bottom with a round of parchment paper, then butter parchment.
Sift together flour, baking powder, baking soda, and salt.
Beat together butter and sugar in a large bowl with an electric mixer until pale and fluffy. Beat in vanilla. Add eggs 1 at a time, beating well after each addition. With mixer at low speed, beat in buttermilk until just combined. Add flour mixture in 3 batches, mixing after each addition until just combined.
Spread batter in cake pan, smoothing top. Rap pan on counter several times to eliminate air bubbles.
Bake until golden and a wooden pick inserted in center comes out clean, 35 to 40 minutes. Cool in pan on a rack 10 minutes. Run a knife around edge of cake to loosen, then invert onto a plate. Discard paper and reinvert cake onto rack to cool completely.
Bring water and sugar to a boil in a small heavy saucepan, stirring until sugar has dissolved. Put berries in a bowl and pour hot syrup over them, gently tossing to coat. Let stand 15 minutes.
Beat mascarpone and cream with sugar in a large bowl using cleaned beaters until mixture just holds stiff peaks.
Halve cake horizontally with a long serrated knife. Carefully remove top half and reserve. Put bottom half on a plate, then spread evenly with all of cream and replace top half. Serve with berries. Dust with sifted confectioners sugar.
