This delicious Coffee Cake is made with a yellow cake mix, layered w/ a cinnamon, butter and pecan swirl, and topped with vanilla glaze! So easy to make!
Preheat oven to 350 degrees and prepare a 9x13 inch pan by spraying with baking spray.
In a medium bowl, combine ⅔ cup of the dry yellow cake mix with the cinnamon, melted butter, brown sugar and chopped pecans. Mix with a fork until the mixture looks like wet sand. Set aside.(Yes, it is 2 tablespoon of cinnamon, not a typo)
2 Tbsp. cinnamon, 3 Tbsp. butter, ½ cup brown sugar, ½ cup chopped pecans
In a separate large mixing bowl, combine the remaining dry yellow cake mix with the eggs, sour cream and vanilla. Mix on low speed with an electric mixer until just combined. Then mix for 1 minute on medium speed.
3 eggs, 1 ½ cups sour cream, 2 tsp. vanilla
Time to layer the coffee cake, an offset spatula can make this a little easier! Pour half of the batter into the prepared 9x13 inch pan. Spread evenly. Sprinkle half of the brown sugar mixture over the batter.
Top with the rest of the batter and try to spread as evenly as possible.
Sprinkle the remaining brown sugar mixture over the top.
Bake at 350℉ for approximately 30 minutes or until golden brown and when a toothpick inserted into the middle of the cake comes out clean.
While the cake is baking prepare the icing. Mix all the icing ingredients in a bowl and stir until it becomes a thick drizzling consistency.
