Chocolate Pudding Cake

Preheat oven to 350°F. Grease the bottom and sides of a 9” x 9” square cake pan generously with cooking spray.
Chocolate Cake: In a large mixing bowl, combine the flour, sugar, cocoa, baking soda, baking powder, and salt with a whisk until combined. Add the eggs, vanilla, oil, and water and whisk until combined and smooth, about 1 minute.
Pour the cake batter into the prepared pan. Bake for 28-30 minutes or until the center of the cake springs back to the touch (or a toothpick comes out mostly clean). Immediately poke several holes in the cake with the end of a wooden spoon or a wooden dowel. Set aside.
Chocolate Pudding: In a medium saucepan, combine the sugar, cocoa, cornstarch, and espresso powder. Slowly stream in the milk while whisking.
Cook the pudding mixture on the stove over low heat and stir continuously with a rubber spatula until the mixture thickens and starts to boil, about 15-20 minutes.
Immediately pour the hot pudding over the warm cake, allowing the pudding to fill each of the holes you poked in the cake. Spread the remaining pudding all over the top of the cake. Press a piece of plastic wrap directly on the top of the pudding and refrigerate for 8 hours or overnight.
Once the cake is chilled, add sprinkles (if desired), cut it into slices, serve, and enjoy!
