Instructions

Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and flour a 9-inch round or square baking pan to prevent sticking and ensure even baking.
Make the Cake Batter: In a large bowl, combine the yellow cake mix, sour cream, vegetable oil, eggs, and vanilla extract. Beat with a hand mixer or whisk vigorously for about 2 minutes until the mixture is smooth and fully combined.
Make the Streusel Topping: In a separate small bowl, mix together the brown sugar, all-purpose flour, and ground cinnamon. Add the softened unsalted butter and blend everything with a fork or your fingers until the mixture becomes crumbly and coarse.
Layer the Cake and Streusel: Pour half of the cake batter into the prepared baking pan and level it evenly. Sprinkle half of the streusel topping evenly over the batter.
Add Remaining Batter and Streusel: Spread the remaining cake batter on top of the first streusel layer, smoothing it out evenly. Then, sprinkle the remaining streusel mixture on top for a crunchy finish.
Bake: Place the pan in the preheated oven and bake for 35-40 minutes. Check doneness by inserting a toothpick into the center; it should come out clean. If the top browns too quickly during baking, cover loosely with aluminum foil to prevent burning.
Cool and Serve: Allow the coffee cake to cool in the pan for about 10 minutes, then transfer it to a wire rack to cool slightly. Slice into 12 servings and serve warm or at room temperature alongside your favorite coffee or tea.

Notes

Use a hand mixer or whisk to ensure the cake batter is smooth without overmixing.
Softening the butter for the streusel helps achieve the crumbly texture needed for topping.
If you prefer a gluten-free version, substitute the cake mix and flour accordingly.
Storing leftovers in an airtight container keeps the coffee cake fresh for up to 3 days.
For added texture, you can sprinkle chopped nuts such as walnuts or pecans into the streusel mixture.
