ingredients on back of cake box
1/4 cup Irish Cream
Filling:
1 (14-ounce) can sweetened condensed milk
1/3 cup heavy cream
1/3 cup unsweetened cocoa powder
1/4 cup Irish Cream
Frosting:
2 cups heavy cream
3/4 cup powdered sugar
1/4 cup unsweetened cocoa powder
2 tablespoons Irish Cream
grated chocolate for garnish, optional
Make cake in a 9x13-inch pan according to package directions, EXCEPT trade out 1/4 cup of water for Irish Cream. (For example, if box says to add 1 1/4 cups water, add 1 cup water and 1/4 cup Irish Cream.) Let cake cool for 10 minutes and then poke holes all over the top with the end of a wooden spoon. In a medium bowl, whisk together sweetened condensed milk, heavy cream, cocoa powder, and Irish Cream. Slowly pour over cake. Refrigerate for 1 hour. To make frosting, place all ingredients in a mixing bowl. Beat with electric mixer until mixture gets thick. Spread over cake. Keep refrigerated. Sprinkle with grated chocolate if desired.
