    why this blueberry crumb cake is the best

    • Blueberry cake: This cake has a delicious blueberry jam layer that is made with real blueberries! It's the blueberry version of my popular strawberry crumb cake!
    • Easy recipe: While there are three components of the cake, they come together easily with just a few staple ingredients.
    • Tender cake: It has a soft, moist, and perfectly tender texture!
    • Serve it for any occasion: While it's perfect for dessert if you need a breakfast or brunch treat, it's basically a fancier version of blueberry coffee cake!

    ingredient notes & substitutions

    ingredients needed to make blueberry cake in bowls with labels.

    Blueberries: You can use frozen or fresh blueberries. I prefer frozen wild blueberries for the best blueberry flavor and jammy texture like my blueberry crumble blondies.

    Buttermilk: I recommend using store-bought full-fat buttermilk, I don't recommend substituting this ingredient.

    Butter: If you want to use salted butter, omit ½ teaspoon of salt from the recipe.

    Full ingredient measurements and instructions can be found in the recipe card below!

    recipe instructions

    Before you start: Line a square 8x8 baking pan with parchment paper. In a large bowl, whisk together the flour, salt, and baking powder and set it aside. Then preheat the oven to 350 F/180 C.

    Step 1: Make the crumb topping. In a medium bowl, combine the all-purpose flour, granulated sugar, light brown sugar, and melted butter until large crumbs form. Place the bowl in the fridge to chill until ready to use (image 1 below).

    Step 2: Prep the blueberries. In a separate bowl, combine the frozen wild blueberries, all-purpose flour, sugar, and lemon juice until evenly coated. Set aside (image 2 below).

    Step 3: Make the cake batter. In a stand mixer, cream the unsalted butter and granulated sugar with the paddle attachment on low speed until light and fluffy, about 5 minutes.

    Slowly stream in the eggs and vanilla extract, mixing until completely combined.

    Then add in half of the dry ingredients, the buttermilk, and the rest of the flour mixture, mixing until just combined.

    Evenly spread the thick batter into the prepared baking dish with a rubber spatula or offset spatula (image 3 above).

    Step 4: Layer the blueberries. Evenly distribute the frozen blueberries on top of the cake batter (image 4 above).

    Step 5: Bake! Evenly sprinkle the crumb topping over the top of the blueberries. Bake on the middle rack of the oven until the middle is puffy and a toothpick inserted into the center comes out clean (image 5 above).

    For cakes made with fresh blueberries: Bake for 55-60 minutes.

    For cakes made with frozen blueberries: Bake for 65-75 minutes.

    Let the cake pan cool on a wire rack for 20-30 minutes, then pull the parchment sides to lift it out of the pan and allow it to cool completely before serving.

    expert baking tips

    • Use a kitchen scale: Baking with a scale is faster, easier, and overall much more accurate than cup measurements.
    • Use room temperature ingredients: Using room temperature ingredients creates a smooth, fully blended batter that will result in a uniform texture and even baking.
    • Chill the crumb: If you don't chill it before baking, the butter will melt too quickly and the crumb will melt together.
    • Baking times may vary: Frozen vs. fresh blueberries will bake differently! Because the frozen berries are juicier and hold more water, the cake will bake for at least 10-15 minutes longer than with fresh berries.

    storage & freezing

    For best results, store any leftover cake in an airtight container or ziplock bag in the fridge for 3-4 days.

    You can also freeze the cake as a whole or individually sliced, in a freezer bag or airtight container for up to one month.

    recipe faqs

    Can I use fresh blueberries instead?

    Definitely! I recommend using only 2 cups of fresh blueberries instead of 2 ½ cups.

    Can blueberry crumble cake be made with gluten-free flour?

    I have not tested this recipe with gluten-free flour but I would love to hear how it turns out if you do!

    I don't like blueberries, can I use a different berry?

    Yes! You can make strawberry crumble cake or substitute the blueberries for blackberries or raspberries.

    Why does my cake crumble when I cut it?

    Too much flour can cause the cake to be dry and crumbly. My #1 tip when baking is to use a kitchen scale for accuracy!

    Notes

    Step-by-step process photos are provided above, in the body of this post.
    *To substitute fresh blueberries, use 2 cups (280 g) and bake for 55-60 minutes.
    *Measure your flour properly. This is my #1 baking tip! Do not ever scoop a measuring cup into your flour as this always leads to using too much flour. Instead, use the spoon-level method. This means fluffing the flour first, then spooning it into your measuring cup/spoon. For the BEST results, use a kitchen scale!*

      Every recipe I follow from this website turns out amazing. The steps are so easy to follow, and I love that you put the amounts of eat item in the instructions, it makes following this recipe so much easier.
      I made this recipe for the first time and now I realize I have to triple the recipe if I want to have more than 1 slice for myself.
      I live with a bunch of health nuts and they couldn’t even resist.

      Made this with mixed berries. Turned out great! Next time, I’ll play with the flavors a bit to add some complexity to the cake…lavender, almond extract etc…

        Hi Rachel! I haven't tested it myself but I think it should work just fine! The baking time may be a little bit different though.

      Oh my goodness, it is so delicious, perfectly moist and loved the bursts from the blueberries. Love how buttery the cake part this and then the small bits of crunch from the crumble part adds a nice textural mouth feel. 10/10 would make this again. I will say I used fresh blueberries instead of frozen, it was what I had on hand and the recipe turned out great. Thanks for this beautiful recipe!
