This Lemon Meringue Cake features layers of soft sponge cake filled with tangy lemon curd and topped with fluffy, toasted meringue. Begin by baking the cake layers, then prepare the lemon curd. Assemble by spreading curd between layers, finishing with meringue. Torch the meringue until golden for a show-stopping dessert with the perfect balance of sweet and tart.
Preheat oven to 350°F (175°C). Grease and flour two round cake pans. Cream 1 cup butter with 2 cups sugar until fluffy. Add 4 eggs one at a time, then mix in 1 tsp vanilla, zest of 2 lemons, and 2 tbsp lemon juice.
In another bowl, sift 3 cups flour, 1 tbsp baking powder, and ½ tsp salt. Add to the wet mix, alternating with 1 cup milk. Divide between pans and bake for 30–35 mins. Cool completely.
Make lemon curd in a saucepan, whisk 1 cup sugar, 2 tbsp cornstarch, 1 cup water, and ½ cup lemon juice. Cook over medium heat until thick.
In a separate bowl, beat 4 egg yolks. Slowly whisk in a bit of the hot lemon mix, and then pour back into the pot. Cook 2–3 mines more. Remove from heat, stir in 2 tbsp butter and zest of 1 lemon. Let cool.
Make meringue to beat 4 egg whites with ¼ tsp cream of tartar until soft peaks form. Gradually add ½ cup sugar and ½ tsp vanilla. Beat until stiff and glossy.
