Tropical Dulce de Leche Cake

Two weeks ago, my parents and I were invited to go have dinner at some friends' house. My mom, as always, volunteered to bring dessert. Then she came to me, saying that she had thought of a cake recipe based on a Brazilian dessert. 

Here's the recipe:

1 9x13" white sheet cake

1 recipe buttercream frosting

1 jar dulce de leche

1 can crushed pineapple

sweetened coconut shavings (the kind you get in bags at the grocery store)

First, cut the cake into two layers and then in half. Put one quarter of the cake on your cake board. Put one layer of dulce de leche on. Put another quarter of the cake on top, then a layer of crushed pineapple. Then the third quarter and another layer of dulce de leche. Put on the final layer and cover the entire cake with buttercream. Before the buttercream hardens, pat the coconut all over. Makes 20 servings.
