Coffee cake was always my family’s favorite dessert growing up! It was essential for weekend brunch, especially when we had company. I’ve been making this recipe for the last few years, and it quickly became one of my go-to’s when I have friends and family visiting because everyone loves it!

This recipe uses sour cream to add moisture to the cake and fresh blueberries baked in the center for a burst of berry flavor. It reminds me of a blueberry crumb muffin, but soo much better! It’s fluffy and moist, and that cinnamon sugar crumble in every bite is what I love most.

It’s the perfect treat to pair with a hot cup of coffee any day of the week!

Ingredients

See the recipe card below for the complete recipe list and measurements.

Dry ingredients: for the cake’s dry ingredients, you’ll need all-purpose flour, salt, baking powder, baking soda, cinnamon, and coconut sugar for a natural sweetener (you can also use white sugar). Blueberries are also added to the center of the cake for fresh berry flavor!

Wet ingredients: To add moisture to the cake, you’ll need butter (both for the cake and the crumble), sour cream, vanilla extract, eggs, and a little milk.

How to Make Sour Cream Coffee Cake with Blueberries

1

Make the crumble. First, mix together the topping ingredients in a small bowl until they resemble a crumbly consistency. Then set aside for later.
2

Whip the butter and sugar. Next use a hand-held or standing mixer to whip the room temperature butter and sugar together for 2 minutes.
3

Add the remaining wet ingredients. Then add the eggs and vanilla, and mix on low until fully combined with the whipped butter and sugar. Then stir in the sour cream.

4

Add the dry ingredients to the wet ingredients. Then, in with the wet ingredients add the flour, salt, baking powder, and baking soda. Fold these ingredients together until completely combined, but do not over mix. Toward the end of stirring add the milk.
5

Add the bottom layer of the cake to the pan. Line a 8×8 baking pan with parchment paper, with the edges up so you can transfer the cake out later. Take half the cake batter and spread it out onto the pan with the parchment paper.
6

Layer half the crumble topping and blueberries. On top of the cake filling, evenly sprinkle half of the crumble topping and fresh blueberries.

Add batter over center filling. Add the remaining batter in dollops over top of the center, this will make spreading the batter easier.
8

Spread the remaining batter. Then spread the batter evenly over top of the center filling.
9

Top with crumble and bake. Sprinkle the remaining crumble over the top of the cake, then bake at 350F for 35-40 minutes. Use a toothpick to test until it comes out clean, then let the cake cool for about 15-20 minutes. Use the edges of the parchment paper to lift the cake out of the tin, then slice into 9 pieces. Serve!

Tips for Success

Spreading the batter can be tricky. Because this cake has a few layers, it can be tricky to spread the batter evenly. I like to dollop the batter in different places and then spread it. It makes for less mess and is way easier to spread!

Don’t grease the pan – use parchment paper. Lining the cake pan with parchment is the easiest way to transfer the baked cake from the pan! You can do it with oil, but getting the cake out of the pan without breaking some of the cake will be almost impossible.

Make it dairy-free. If you’d prefer to use no dairy in this cake, you can use vegan/plant-based butter, milk, and sour cream!

Instead of sour cream. This recipe would also work great using plain Greek yogurt!
