Homemade Blueberry Coffee Cake
To make this blueberry coffee cake recipe, I used an easy, no-mixer cake that’s adapted my favorite buttermilk cake base that I’ve used for so many cakes including: Homemade Funfetti Cake, Vanilla Cake with Vanilla Bean Browned Butter Glaze, Lemon Buttermilk Cake with Lemon Glaze, The Best Pineapple Upside-Down Cake, Caramelized Banana Upside-Down Cake and many more. There’s a reason this is a favorite cake base and that’s because not only is it a no-mixer cake that’s so fast and easy to make, but also because the cakes always turn out supremely moist, springy, and fluffy thanks to buttermilk, sour cream, and oil. That trifecta of moisturizing and tenderizing ingredients makes it impossible to have a dry cake. For the streusel topping, I used the same crumb topping in this Pumpkin Crumb Coffee Cake, without the nuts, but you could incorporate them if you you’d like.
I have a thing for crumble or streusel topping and this blueberry sour cream coffee cake was right up my alley. It was still warm when I dug into my first piece on a chilly morning (I made this cake a few months back in anticipation of blueberry season) and it so delicious. The homemade coffee cake itself is incredibly soft, tender, and moist and it’s studded with juicy blueberries throughout. The streusel topping adds the perfect amount of crunchy texture to an otherwise soft and tender cake. Those big buttery crumbles are the best and because I went a little heavier handed than the one-half teaspoon of salt that the recipe calls for, they were like biting into little salty-sweet-buttery-sugary nuggets and for me personally, that’s heavenly. The cake isn’t overly sweet, making it a perfect for mornings with a cup of coffee or tea, for a (holiday) brunch you’re hosting, as a little afternoon snack, or even after dinner when you want a little something sweet but don’t want to go overboard. What I also love about this blueberry coffee cake is that even 5 days later, I had extra pieces wrapped in plastic wrap, which normally makes crumb topping very soggy and soft, but not here. Crumbly perfection even days later.
What’s in Blueberry Coffee Cake?
To make this blueberry streusel coffee cake, you’ll need:
All-purpose flour Granulated sugar Light brown sugar Salt Unsalted butter Baking powder Egg Buttermilk Sour cream Canola oil Vanilla extract Fresh blueberries
How to Make Blueberry Coffee Cake
You’ll first need to make the streusel topping, making sure not to make the pieces too small (you want some to be the size of small pebbles or marbles). Then, stir together the coffee cake batter before folding in the blueberries. Sprinkle the streusel topping onto the cake before baking it. Let the blueberry sour cream coffee cake cool before slicing and serving.
Can I Use Frozen Blueberries?
I made this easy coffee cake with fresh blueberries and haven’t tested it with frozen. My guess, however, is that frozen berries will be fine, but if you’re not familiar with baking with frozen blueberries, they tend to turn the batter and resulting cake a bit blue and sometimes green and it’s not the prettiest. The taste is fine but the appearance won’t necessarily win any awards. If you do use frozen, I would add them straight from the freezer (do not thaw) and you will likely need to add additional baking time since the batter will be cold.
Can I Double This Recipe?
Yes, you’d simply need to double the ingredients and bake this blueberry streusel coffee cake in a 9×13-inch pan.
Tips for Making Blueberry Coffee Cake
If you’d rather not use sour cream, you’re welcome to use plain Greek yogurt instead. Also note that lite sour cream works well in this recipe too. Be careful not to over mix the streusel topping before sprinkling it atop the cake. The streusel should be a sandy mixture with larger, marble-sized pieces running throughout. If your blueberries are on the bigger side and/or you want to prevent some sinking, roll them lightly in flour before adding them to the batter.
