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 GlazeLemon Buttermilk Cake with Lemon GlazeThe 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.

Yield: 9
Prep Time 10 minutes
Cook Time 48 minutes
Additional Time 32 minutes
Total Time 1 hour 30 minutes

Ingredients

Streusel Topping

  • 3/4 cup all-purpose flour, plus 1 to 2 tablespoons more if needed
  • 1/4 cup granulated sugar
  • 1/4 cup light brown sugar, packed
  • 1/2 teaspoon salt, or to taste
  • 6 tablespoons unsalted butter, melted

Cake

  • 1 cup all-purpose flour
  • 3/4 cup granulated sugar
  • 2 teaspoons baking powder
  • 1/2 teaspoons salt, or to taste
  • 1 large egg
  • 1/2 cup buttermilk
  • 1/3 cup sour cream, lite is okay (plain Greek yogurt may be substituted)
  • 1/4 cup canola or vegetable oil
  • 2 teaspoons vanilla extract
  • 1 cup fresh blueberries, plus 1/4 cup more for sprinkling on top if desired

Instructions

  1. Preheat oven to 350F. Line an 8-by-8-inch baking pan with aluminum foil, spray with cooking spray; set aside.

Streusel Topping:

  1. To a medium bowl, add 3/4 cup flour, sugars, salt, and stir with fork to combine.
  2. Drizzle in the melted butter and mix and fluff very lightly with a fork to combine until small marbles and pebbles form. You are not ‘stirring’, you are fluffing lightly and gently. If the dough is very wet and is not fluffing into small pebbles and marbles, add 1 to 2 additional tablespoons of flour; set aside.

Cake:

  1. In a large bowl, whisk together the flour, granulated sugar, baking powder, and salt; set aside.
  2. In a separate small bowl, whisk together the egg, buttermilk, sour cream, oil, and vanilla.
  3. Add the wet mixture to the dry, mixing lightly with a spoon or folding with a spatula until just combined. Small lumps will be present, don’t overmix or try to stir them smooth.
  4. Add 1 cup blueberries and stir to combine. Tip – 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.
  5. Turn batter out into prepared pan.
  6. Evenly sprinkle the topping and bake for about 45 to 50 minutes (start checking at 40 minutes), or until center is set and not jiggly, and a toothpick inserted in the center comes out clean or with a few moist crumbs, but no batter. Since all fruit, pans, ovens, climates, etc. vary if your cake takes longer than 50 minutes to bake through, then bake as needed.
  7. Place pan on a wire rack and allow cake to cool before slicing and serving.

  4. I can’t print the recipe. please help THANK YOU [email protected]

  5. Hi my name is Cathy, just to let you know, you forgot to write in the recipe, about adding the topping. You didn’t write it in the recipe when to add it. Please tell me.

  6. I read the recipe for the Blueberry Streusel Coffee Cake but I don’t see anything in the instructions that say when to put the streusel topping on it. Are you supposed to bake the cake part a little while before putting it on or do you put it on before you start baking the cake?

  7. I am going to try it with apples. I have apples. I will add cinnamon and a bit of nutmeg.

  8. This sounds amazing! I love all things blueberry …. and streusel!
