Pour the soak over the cake; I use a ladle to help and allow to sit until the liquid is absorbed.
While you wait, make the topping, and add the heavy cream, powdered sugar, and vanilla to the body of a stand mixer with the whisk attachment or in a large bowl with an electric hand mixer. Beat until stiff peaks form.
1 1/2 cup heavy whipping cream, 3/4 cup powdered sugar, 1 teaspoon vanilla extract
Smooth the topping over the cake, cover, and place in the fridge for at least 8 hours or overnight.
Sprinkle a little ground cinnamon over the top if desired, slice, and serve.
ground cinnamon for garnish
Notes
Beat those egg whites to stiff peaks—it’s the secret to an airy sponge cake!
Use a large bowl for mixing—gives you room to fold without a mess!
Poke holes all over with a fork.
Whisk the milk mixture in a medium bowl.
Let it chill overnight—makes the cake cool and the flavors pop!
Spread the whipped cream frosting evenly—looks pretty and tastes great!
