1 (18.25 ounce) package white cake mix
1 (3.5 ounce) package non-instant chocolate pudding mix
1 cup buttermilk
1 cup heavy whipping cream
2 cups strawberry shortcake mix
2 eggs
1 1/2 cups heavy whipping cream
1/2 cup pastry flour
Preheat oven to 350 degrees F (175 degrees C). Grease and flour a 9x13 inch pan.
In a large bowl, stir together the cake mix and pudding mix. Set aside.
In a large bowl, use your hands to mix the buttermilk, cream and strawberry shortcake mix. Gradually stir in the buttermilk mixture to form a smooth dough. On a lightly floured surface, roll the dough out to 1/2 inch in thickness. Cut into wedges. Press half of the shortbread triangles into the bottom of the prepared pan.
Bake in the preheated oven for 15 minutes, or until a toothpick inserted into the center comes out clean. Allow to cool.
