This buttery almond cake with lemon curd baked inside is like the ultimate citrus tart, without the heartbreak of pie crust. It's fancy enough to be served as a dinner party dessert, yet substantial enough to be served with Sunday brunch. (Bonus: you'll have several tablespoons of lemon curd left over. It's delicious on toast or pancakes.)
Heat oven to 350 degrees. Grease 9-inch spring-form pan with 1 tablespoon butter, and dust with 1 tablespoon flour, shaking out excess.
03With an electric mixer, cream the remaining butter and 1 cup sugar together until light and fluffy. Sift together the remaining flour, baking powder and salt, and stir in. In a separate bowl, whisk eggs until they start to foam. Do not overbeat or the cake will be tough. Add eggs and ground almonds to batter, and mix well.
04Scrape batter into the prepared pan. Drop 8 individual tablespoons lemon curd around perimeter of batter, leaving a 1-inch border, and taking care to space drops evenly. Drop 3 to 4 tablespoons curd into center of batter. Refrigerate remaining curd for another use. Sprinkle cake with toasted almonds and 1 to 2 tablespoons sugar, depending on taste.
05Bake until cake is toasty brown on top and a toothpick inserted into cake (not curd) comes out clean, about 40 minutes. Let cool on rack 10 minutes, then remove sides of pan, and cool completely.
06Whip cream with almond liqueur. Present cake at table, and offer whipped cream on the side.
