Tiramisu Poke Cake

Ingredients 

1. 4 large eggs
2. 2 cups sugar 
3. 1 teaspoon vanilla extract 
4. 2-1/4 cups all-purpose flour 
5. 2-1/4 teaspoons baking powder 
6. 1-1/4 cups 2% milk 
7. 10 tablespoons butter, cubed 
8. 8 ounces espresso coffee 
9. 1 14-ounce can sweetened condensed milk 

Directions 

In a large bowl, beat eggs on high speed for 5 minutes or until thick and lemon-colored. Gradually add sugar, beating until mixture is light and fluffy. Beat in vanilla. Combine flour and baking powder; gradually add to batter; beat at low speed until smooth.
In a small saucepan, heat milk and butter just until butter is melted. Gradually add to batter; beat just until combined.
Pour into a greased 13x9-in. baking pan. Bake at 350° for 30-35 minutes or until a toothpick inserted in the center comes out clean. Cool on a wire rack. Yield: 12-16 servings.

Frosting 

1. 1 1/2 sticks unsalted butter, softened 
2. 1 1/2 teaspoon pure vanilla extract 
3. Kosher salt 
4. 1 1/2 cups mascarpone cheese 
5. 3 cups confectioners’ sugar 

In a large bowl, using a hand mixer, beat the butter with the confectioners sugar, vanilla and a pinch of salt until smooth. Add the mascarpone and beat at high speed just until smooth; do not overbeat. Refrigerate the frosting until just set, about 30 minutes.
