Blueberry Crumb Cake

This Blueberry Crumb Cake is moist, fluffy and has a delicious jammy layer of blueberries tucked under a layer of crunchy, buttery cinnamon crumb topping. This cake can be mixed in one bowl in just a few minutes. Enjoy this for breakfast, brunch or dessert with a scoop of vanilla ice cream.

The details

make the streusel

This Blueberry Crumb Cake comes together quickly, and since the streusel topping uses melted butter and needs time to cool/set up, you’ll want to make this first. I find it is easier to mix the streusel topping evenly with melted butter. Certainly you can use softened butter instead.

To make the streusel, you’ll simply add all ingredients to the bowl, then pour in the melted butter. Use a fork to sort of claw/mix the ingredients together until combined. Set the mixture aside, while you make the crumb cake.

Now, it’s time to make the cake batter for the Blueberry Crumb Cake! As always, I made this process as simple as possible, so it comes together in minutes, and is tough to mess up :). You’ll begin by basically adding all of the wet ingredients +the sugar to your mixing bowl, then mixing to combine. Add the melted butter, sugars, eggs, sour cream, milk and vanilla extract. Whisk to combine.

Next, you’ll add the dry ingredients – the flour, baking powder and soda, cinnamon and salt. Whisk just until combined.

Assemble the cake, then bake!

I like to line my 8×8 pan with parchment paper and spray with nonstick spray to ensure the Blueberry Crumble Cake doesn’t get stuck. What’s worse than putting in all the work only to have the cake get stuck to the pan!?

Pour the batter into your prepared pan, and smooth the top with a spatula to make it smooth. It doesn’t have to be perfect. Next, add your blueberries to a bowl and toss with 1 tablespoon flour. This will help to ensure the blueberries don’t sink. The batter is thick, so they should stay at the top of the cake, but adding the flour helps to ensure that. As the cake bakes, the flour absorbs the extra juices that the blueberries release, thus helping to prevent them from sinking. You’re left with an extra jammy layer of blueberries at the surface of the cake, and it’s so good!

Sprinkle the blueberries evenly over the cake. Now, using your hands, crumble the streusel mixture over the cake. Bake in a 350F preheated oven for 38-42 minutes or until a toothpick inserted into the center comes out clean.

drizzle with icing and enjoy

Once the cake is completely cool, and you are ready to serve it, drizzle with vanilla icing.
