Classic tres leches cake is INCREDIBLY easy to make at home and you won't be able to resist this luscious cake that's soaked in three kinds of milk and topped with fluffy whipped cream.
Preheat oven to 350F. Line a 9x13 pan with parchment paper and set aside.
Separate eggs and place egg whites in a large bowl. Place egg yolks in a large separate bowl. Whisk sugar into egg yolks and beat until mixture is very thick, about 1 minute. Beat in milk and vanilla extract. In a separate bowl, whisk flour, baking powder, and salt. Fold flour mixture into egg mixture.
Using an electric beater, beat egg whites on high speed until stiff peaks are reached. Very gently fold egg whites into egg yolk batter until just combined.
Spread batter into prepared pan and smooth top. Bake cake at 350F 25-30 minutes or until toothpick inserted in middle comes out clean. Let cake cool completely on a wire cooling rack.
Milk Mixture
In a medium bowl, whisk milks together until smooth. Turn cake out onto tray and peel off parchment paper. Using a fork, prick cooled cake all over top.
Slowly pour milk mixture over cake, ensuring milk soaks into every inch of the cake. Cover cake loosely with plastic wrap and refrigerate at least 8 hours or overnight to let the cake soak up all the milk.
Whipped Cream
In a medium bowl with an electric mixer, beat whipping cream on high speed until soft peaks form. Add powdered sugar and vanilla and whip until stiff peaks form.
Spread whipped cream over tres leches cake. Lightly sprinkle with ground cinnamon. Slice cake and enjoy!
