Creating a delicious Pecan Pie Cake is easy if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking pan.
2. Mix Dry Ingredients: In a large bowl, whisk together the flour, baking powder, baking soda, and salt until combined.
3. Cream Butter and Sugar: In another bowl, using an electric mixer, cream the softened butter and granulated sugar until light and fluffy.
4. Add Eggs and Vanilla: Beat in the eggs one at a time, mixing well after each addition. Then, blend in the vanilla extract.
5. Combine Wet Ingredients: Alternately add the dry mixture and buttermilk to the butter mixture, starting and ending with the dry ingredients. Mix until just combined.
6. Stir in Pecans: Gently fold the chopped pecans into the batter until evenly distributed.
7. Pour Batter: Pour the batter into the prepared baking pan, smoothing the top for even baking.
8. Bake: Place in the preheated oven and bake for 40-50 minutes or until a toothpick inserted in the center comes out clean.
9. Prepare Topping (while the cake bakes): In a bowl, combine the light corn syrup, brown sugar, melted butter, and additional vanilla extract to create the topping.
10. Add Topping: Once the cake is done baking, remove it from the oven and immediately pour the pecan topping over the cake while it is still warm.
11. Return to Oven: Bake the cake for an additional 10-15 minutes until the topping is bubbly and set.
12. Cool the Cake: Allow the cake to cool in the pan for at least 30 minutes before serving.

By following these steps, you will create a sensational Pecan Pie Cake that brings delightful flavors and joy to any gathering!
