What Kind of Cake Mix Should I Use?

The base of this coffee cake is surprisingly straightforward: a box of yellow cake mix. It saves time and guarantees that soft, moist texture Starbucks lovers expect. While you can use your favorite brand, just make sure it’s a classic yellow mix—not butter golden or vanilla—to keep the flavor profile true to the original.

How To Make the Easy Copycat Starbucks Coffee Cake

Step 1: Prepare the Cake Batter

Start by preheating your oven to 350°F and greasing a 9×13-inch baking pan. In a large mixing bowl, combine the yellow cake mix, eggs, sour cream, and oil. Beat until the mixture is smooth and well-blended.

Step 2: Make the Cinnamon Filling

In a small bowl, mix together brown sugar and cinnamon. Pour half the cake batter into the prepared pan, then evenly sprinkle the cinnamon sugar mixture over it. Pour the remaining batter over the top and gently spread it out.

Step 3: Create the Crumb Topping

Using a fork or pastry cutter, combine brown sugar, flour, cinnamon, and cold butter until the mixture is crumbly and resembles coarse sand. Generously sprinkle this over the entire cake batter.

Step 4: Bake to Perfection

Bake the cake in the preheated oven for 35 to 40 minutes, or until a toothpick inserted in the center comes out clean. The topping should be golden and slightly crisp.

Step 5: Drizzle the Icing

Once the cake has cooled slightly, mix powdered sugar with milk to create a smooth glaze. Drizzle it over the top of the cake for that classic Starbucks look and a little extra sweetness.
