This Blueberry Coffee Cake is so yummy! It’s super soft and packed with juicy blueberries. Plus, it’s made with sour cream, which makes it extra fluffy and delicious. And let’s not forget that amazing streusel on top and the creamy cream cheese glaze.
The best part? It’s a breeze to whip up! In just 30 minutes, you’ll have this delightful cake ready to pop in the oven. Then, all that’s left to do is bake it and wait a bit for it to cool before slicing—temptation alert!
Here are some tips to ensure your coffee cake turns out perfect every time:
- When you add the flour, be gentle! Over-mixing can make the batter dry or tough.
- Make sure your ingredients are at room temperature—your butter, eggs, and sour cream will thank you.
- Keep an eye on your baking time. You want the edges and top of your cake to be nicely browned, and a toothpick inserted in the center should come out clean. No jiggly middle allowed!
