Preheat the oven to 350 degrees Fahrenheit and spray a 9X13 baking pan with non-stick cooking spray.

Mix together the topping ingredients and set aside.

In a large mixing bowl, beat together the butter and sugar with a hand held mixer or stand up mixer until light and fluffy.  Add in the eggs, one at a time.

Then add in the sour cream, vanilla extract and mix until combined and smooth.

Then hand stir in the flour, baking powder, baking soda and salt until just combined.  Be careful to not over mix.

Pour half of the batter into the prepared pan.  Top with half of the topping mixture.

Then pour the remaining batter into the pan and top with the remaining topping mixture.

Bake for 30-35 minutes until the top of the cake is golden brown and a toothpick inserted into the center of the cake comes out clean.

Remove the cake from the oven.  Allow it to cool for 10-15 minutes.  Then it’s ready to serve and enjoy!
