Tiramisu Layer Cake

So, my parents 30th Anniversary was on Tuesday and I wanted to bake them a Tiramisu Cake
( my mom's favorite), but by the time I got home from work there really wasn't any time left for me to bake it that night. I had a half day on Wednesday, so I decided to do it that day along with the pies I was baking for Thanksgiving.

I have no idea who I got this recipe from, I know it was from someone's blog.. but no idea who. If this is your recipe or if you know who's recipe this is please let me know, so I can give proper credit to the owner.

This cake was delicious and very easy to make, this recipe is a keeper!

Tiramisu Layer Cake

CAKE

1 (18.25oz) package moist white cake mix
1 teaspoon instant coffee
1/4 cup coffee
1 tablespoon coffee flavored liqueur ( I used Kahlua, the original one)

FILLING
1 (8oz) container mascarpone cheese
1/2 cup confectioners sugar
2 tablespoons coffee flavored liqueur

FROSTING
2 cups heavy cream
1/4 cup confectioners sugar
2 tablespoons coffee flavored liqueur

GARNISH
2 tablespoons unsweetened cocoa powder
1 (1oz) square semisweet chocolate

1. Preheat oven to 350 degrees F. Grease and flour 3 (9in) pans.
2. Prepare the cake mix according to package directions. Divide two thirds of batter between 2 pans. Stir in instant coffee into remaining batter; pour into remaining pan.
3. Bake in the preheated oven for 20-25 min. or until a toothpick inserted into the center of the cake comes out clean. Let cool in pan for 10 minutes, then turn out onto a wire rack and cool completely. In a measuring cup, combine brewed coffee and 1 tablespoon coffee liqueur; set aside.
4. To make the filling: In a small bowl, using an electric mixer set on low speed, combine mascarpone, 1/2 cup confectioners sugar and 2 tablespoons coffee liqueur; beat just until smooth. Cover with plastic wrap and refrigerate.
5. To make the frosting: In a medium bowl, using an electric mixer set on medium-high speed, beat the cream, 1/4 cup confectioners sugar and 2 tablespoons coffee liqueur until stiff. Fold 1/2 cup of cream mixture into filling mixture.
6. To assemble the cake: Place one plain cake layer on serving plate. Using a thin skewer, poke holes in cake, about 1 inch apart. Pour one third of the reserved coffee mixture over cake, then spread with half of the filling mixture. Top with coffee flavored cake layer, poke holes in cake, pour another third of the coffee mixture over the second layer and spread with the remaining filling. Top with remaining cake layer; poke holes in cake. Pour remaining coffee mixture on top. Spread sides and top of cake with frosting. Place cocoa in a sieve and lightly dust top of cake. Garnish with chocolate curls. Refrigerate at least 30 minutes before serving.
7. To make the chocolate curls, use a vegetable peeler and run it down the edg of the chocolate bar.
