German Chocolate Poke Cake

Make The Frosting:: Beat the softened butter until light and fluffy, about 2 minutes. Add powdered sugar one cup at a time, alternating with small amounts of milk to maintain a spreadable consistency. Mix in the remaining caramel sauce until fully incorporated.
Add The Signature Mix-ins:: Gently fold in the chopped pecans and coconut with a spatula, being careful not to deflate the frosting. Leave some texture rather than mixing until completely smooth for that classic German chocolate cake experience.
Frost And Chill:: Spread the frosting evenly over the entire cake, creating decorative swirls if desired. Refrigerate for at least one hour before serving to allow the flavors to meld and the filling to set properly.
