Pumpkin Streusel Coffee Cake

Step 1
Preheat the oven to 350 degrees F (175 degrees C). Spray a 9×13-inch pan with cooking spray and set aside.

Step 2
Combine brown sugar, flour, and pumpkin pie spice in a medium bowl. Add butter cubes, and use a fork or pastry blender to mix ingredients together until it resembles coarse crumbs.

Step 3
Combine cake mix and butter in a large bowl and beat with an electric mixer on medium speed until well combined. Add eggs, one at at a time, mixing well after each addition. Add pumpkin puree and cinnamon to the bowl, and mix until well blended, about 3 minutes. Stir in pecans.

Step 4
Pour batter into the prepared pan, spreading evenly. Sprinkle streusel topping over the batter.

Step 5
Bake in the preheated oven until a toothpick inserted into the center comes out clean, 40 to 45 minutes. Allow the cake to cool for about 5 minutes before serving.
