Tres Leches Cake

Preheat oven to 350 degrees F. Coat a 9-by-13-inch glass baking dish with cooking spray.

Combine all-purpose flour, whole-wheat flour, baking powder and salt in a medium bowl. Beat eggs, 1/2 cup sugar and vanilla in a stand mixer fitted with a paddle attachment (or with a hand-held electric mixer) on medium-high speed until very light and fluffy, about 10 minutes. Add half the flour mixture; mix on low speed until combined. Add milk and then the remaining flour mixture; mix until just combined. Evenly spread the batter into the prepared baking dish.

Bake the cake until lightly browned and springs back when gently pressed in the center, 20 to 25 minutes. Cool in the pan on a wire rack for 25 minutes.

Whisk condensed milk and evaporated milk in a medium bowl. Poke holes all over the cake with a fork. Slowly pour the milk mixture over the cake and around the edges. Cover and refrigerate at least 2 hours and up to 1 day.

Just before serving, beat cream in a medium bowl with an electric mixer until soft peaks form. Add the remaining 1 tablespoon sugar and continue to beat until stiff peaks form. Spread the whipped cream over the cake. Top with strawberries, if desired.
