桃子和奶油冰淇淋蛋糕

Preheat the oven to 350°. Butter a 9-inch round springform pan and line the bottom with parchment paper. Butter the parchment. In a medium bowl, whisk the flour with the baking powder, baking soda and 1/4 teaspoon of salt. In the bowl of a stand mixer fitted with the paddle, beat the stick of butter with 1 cup of the sugar and the vanilla seeds at medium-high speed until light and fluffy, about 4 minutes. Beat in the eggs, one at a time. At low speed, alternately beat in the dry ingredients and buttermilk until just combined.

Scrape the batter into the prepared pan and bake for about 35 minutes, until a toothpick inserted in the center comes out clean. Let the cake cool on a wire rack for 30 minutes, then remove the ring and let cool completely.

与此同时,在一个中等大小的平底锅,把桃子chunks with 1 cup of the sugar and a large pinch of salt. Bring to a boil, stirring until the sugar is dissolved, then simmer over moderate heat, stirring occasionally, until the fruit is broken down and the sugar is just beginning to caramelize, about 20 minutes. Let cool.

用锯齿刀修剪蛋糕以形成一个7英寸的圆圈，然后修剪圆顶的顶部以使其弄平；保留废料以供另一种用途。丢弃羊皮纸。将蛋糕水平切成2个均匀的层，然后将它们并排放在烤盘上。将桃子果酱均匀地撒在两个蛋糕的顶部。冻结直到果酱坚固，大约15分钟。

Place a clean 9-inch springform pan on a rimmed baking sheet. Place one of the cake rounds in the center of the springform pan. Spread 2 1/2 pints of the ice cream over the jam and around the side of the cake, filling the space between the cake and the pan. Level the ice cream with an offset spatula. Freeze until the ice cream is firm, about 20 minutes.

将第二个蛋糕层放在第一个蛋糕上。与第一层一样，将剩余的2 1/2品脱冰淇淋撒在果酱和蛋糕侧面。将冰淇淋与偏移刮刀平整；冰淇淋应与弹簧盘的顶部一起冲洗。盖上并冷冻过夜。

Rub a hot, wet towel around the outside of the pan to loosen the cake. Remove the ring and transfer the cake to a platter. Return the cake to the freezer.

In the bowl of a stand mixer fitted with the whisk, beat the heavy cream with the remaining 1 tablespoon of sugar until firm peaks form. Spread the whipped cream on top of the cake and arrange the peach wedges in a decorative pattern on top. Freeze the cake for 20 minutes before serving.
