Ingredients
Cake Base
- 1 package Betty Crocker Wild Blueberry Muffin Mix (It is important to use this specific mix for the right texture and flavor)
- ⅔ cup sour cream
- 1 egg
- ⅓ cup milk
Streusel Topping
- ½ cup brown sugar, packed
- ⅓ cup all-purpose flour
- ½ teaspoon cinnamon
- ¼ cup butter, cold and cut into small cubes
Instructions
1. Preparing the Ingredients
Start by preheating your oven to 400°F (200°C). Grease an 8×8-inch baking pan with butter or non-stick spray to prevent sticking.
Open the Betty Crocker Wild Blueberry Muffin Mix and remove the contents. The mix will contain a small can of blueberries—drain and rinse them thoroughly, then set them aside.
2. Mixing the Batter
In a large mixing bowl, whisk together sour cream and egg until smooth. Gradually add the milk, stirring continuously until fully combined.
Next, add the muffin mix to the wet ingredients. Stir gently just until combined—avoid overmixing, as this can lead to a dense, tough cake. The batter should be slightly lumpy but well incorporated.
3. Making the Streusel Topping
In a separate bowl, combine brown sugar, flour, and cinnamon. Add the cold butter cubes and use a fork or pastry cutter to mix until a coarse, crumbly texture forms. The butter should be evenly distributed, creating small clumps.
4. Assembling the Coffee Cake
Pour half of the batter into the greased 8×8-inch pan, spreading it evenly. Sprinkle half of the streusel mixture over the batter.
Pour the remaining batter over the streusel layer and carefully spread it evenly. Top with drained blueberries and the remaining streusel topping.
5. Baking the Coffee Cake
Place the pan in the preheated oven and bake for 35 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean.
Remove from the oven and let the cake cool for 15–20 minutes before slicing and serving.a
Notes
1. Avoid Overmixing the Batter
Overmixing the batter can lead to a dense, tough cake. Stir the ingredients just until they are combined to keep the cake light and fluffy.
2. How to Tell if the Cake is Fully Baked
To check if the cake is done, insert a toothpick or skewer into the center. If it comes out clean or with a few crumbs (but no wet batter), the cake is ready. If the top is browning too quickly but the inside isn’t fully cooked, loosely cover the pan with foil and continue baking.
3. Make-Ahead Option
If you want to save time in the morning, you can assemble the cake the night before and store it in the refrigerator. When ready to bake, place it in the oven and add a few extra minutes to the baking time.
4. Customizing the Recipe
- Add chopped nuts (such as walnuts or pecans) to the streusel for extra crunch.
- For a citrus twist, add lemon zest to the batter.
- Swap blueberries for raspberries, blackberries, or chopped strawberries for variety.
