→ Topping

01 - 1 egg
02 - 4 tablespoons granulated sugar
03 - 1 tablespoon cornstarch
04 - 1 cup whole milk
05 - 2 teaspoons vanilla extract

→ Cake

06 - 1 1/2 apples, peeled, cored, and diced
07 - Juice of 1/2 lemon
08 - 1/2 cup granulated sugar
09 - Pinch of salt
10 - 2 eggs
11 - 2 teaspoons vanilla extract
12 - 1/2 cup whole milk
13 - 1 2/3 cups all-purpose flour
14 - 2 teaspoons baking powder
15 - Powdered sugar for dusting

# Instructions:

01 - In a medium saucepan, combine the egg, granulated sugar, and cornstarch. Stir in the milk and heat over medium-low until frothy, whisking constantly. Once it begins to bubble, cook for 5-10 minutes while still whisking. Remove from heat, add vanilla extract, and stir well. Set aside.
02 - Peel, core, and dice the apples into large pieces. Toss them in a medium bowl with the juice of half a lemon.
03 - In a large bowl, combine granulated sugar, salt, and eggs. Use an electric mixer to blend until pale and frothy. Add vanilla extract and milk, then mix together.
04 - Sift the flour and baking powder into the wet ingredients. Blend until just combined, scraping down the sides of the bowl as needed.
05 - Fold the diced apples into the batter. Pour the mixture into a 9-inch tart or pie pan lined with parchment paper.
06 - Scoop the custard topping into a piping or Ziploc bag. Cut the tip off one corner and pipe a swirl of custard starting from the center outward until all custard is used.
07 - Bake the cake in a preheated oven at 350°F (175°C) for 30 minutes, or until the top begins to turn golden brown. If the top browns too quickly, cover with foil partway through baking.
08 - Allow the cake to cool for at least 1 hour at room temperature before removing it from the pan. Gently cover the top with a flat plate or cookie sheet, then turn the cake upside down and remove the parchment paper. Flip it back right side up, sprinkle with sifted powdered sugar, and cut into 8-12 slices.
