A soft sponge cake soaked in three kinds of milk until it’s creamy all the way through, but still holds its shape. Finished with whipped cream and best made ahead.
Preheat the oven to 350°F. Grease a 9×13-inch baking pan.
In a bowl, sift together the flour, baking powder, and salt. Set aside.
Combine the milk and butter in a microwave-safe bowl and heat until the butter is melted and the mixture is warm to the touch. Stir in the vanilla and set aside. If it cools too much while you prepare the batter, give it a quick reheat so it stays warm.
In a stand mixer, beat the eggs and sugar on medium-high speed for about 10 minutes, until the mixture is pale yellow, thick, foamy, and noticeably increased in volume. When you lift the whisk, the mixture should fall back into the bowl in soft ribbons that take a second to blend back in Don’t rush this step; it builds the structure that helps the cake absorb the milk soak.
Reduce speed to low. Add half the flour mixture, then the milk mixture, then the remaining flour. Use a wide spatula to make sure everything is fully incorporated.
Pour the batter into the pan and smooth the top. Bake for 25 to 30 minutes, or until the center springs back and a toothpick comes out clean. Let the cake cool in the pan for 20 minutes.
Add the Milk Mixture
In a large measuring cup or bowl, whisk together the heavy cream, evaporated milk, condensed milk, and vanilla.
Use a skewer or fork to poke holes all over the warm cake.
Slowly pour the milk mixture over the cake, letting it soak in before adding more. Take your time here so it absorbs evenly. Cover and refrigerate for at least 6 hours, or overnight.
Make the Whipped Cream
Beat the heavy cream, powdered sugar, and vanilla on high speed until soft peaks form. Spread over the top of the cake. Serve with fresh berries if desired.
Notes
Room temperature eggs: Let the eggs sit out before starting. They beat up with more volume, which gives the cake its light sponge texture.Don’t rush the mixing: Beating the eggs and sugar for the full time is what builds the structure. If you cut it short, the cake won’t absorb the milk as well.Pour the milk slowly: Add the milk mixture gradually and give it time to absorb. Dumping it all at once leads to uneven soaking.Chill time matters: The cake needs several hours to fully soak and settle. It’s best made the day before serving.
