Preheat the Oven: Start by preheating your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan to ensure your cake releases easily after baking.
Mix the Batter: In a large mixing bowl, combine the butter pecan cake mix, coconut pecan frosting, eggs, vegetable oil, and milk. Beat everything together until it is well combined and smooth.
Bake the Cake: Pour the batter into your prepared baking pan and bake for 30-35 minutes. To ensure it’s fully cooked, insert a toothpick into the center—if it comes out clean, it’s ready!
Poke Holes: Once the cake is baked and still warm, use a fork to poke holes all over the top. This step is crucial as it allows the frosting to seep into the cake and adds to its moistness.
Pour the Frosting: Carefully pour the remaining coconut pecan frosting over the warm cake, making sure it fills all the holes for maximum flavor.
Add Pecans: Top the frosted cake with the chopped pecans, adding a crispy element that complements the softness of the cake.
Cool and Serve: Let the cake cool completely before slicing and serving.
