Why You’ll Love Gluten-Free Blueberry Coffee Cake with Pecan Streusel Recipe

This recipe delivers everything a great coffee cake should have: a soft, moist crumb, plenty of fruit, and a sweet, crunchy topping. The combination of oat flour, sorghum flour, sweet rice flour, and tapioca flour creates a tender texture without gluten, while sour cream keeps the cake rich and fluffy.

You’ll also love how the layers come together. Blueberries are tucked into the center for bursts of jammy sweetness, and the streusel bakes into golden clumps that add just the right crunch. It is a lovely make-ahead option for breakfast, brunch, or dessert, and it works with fresh or frozen blueberries.

Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

For the streusel topping:

⅓ cup blanched almond flour
⅓ cup coarsely chopped or broken pecans
¼ cup old fashioned rolled oats
¼ cup gluten-free oat flour
1 tablespoon tapioca flour
⅓ cup packed light brown sugar
½ teaspoon kosher salt
¼ teaspoon ground cinnamon
⅛ teaspoon freshly grated nutmeg
4 tablespoons melted unsalted butter

For the cake:

8 tablespoons unsalted butter, softened, plus 1 teaspoon for the pan
¾ cup light brown sugar
2 large eggs, at room temperature
½ cup sweet white rice flour
½ cup sorghum flour
½ cup gluten-free oat flour
2 tablespoons tapioca flour
2 teaspoons baking powder
½ teaspoon baking soda
½ teaspoon fine sea salt
½ cup sour cream, crème fraîche, or Greek yogurt
1½ teaspoons vanilla extract
2¼ cups fresh or frozen blueberries, plus a few extra for the top
Zest of half a large lemon

Optional for serving:

Powdered sugar
Blueberry glaze
Extra sour cream or yogurt

Directions

Preheat the oven to 350°F. Butter a 9-inch round cake pan or springform pan and line it with parchment paper.
Make the streusel by stirring together the almond flour, pecans, oats, oat flour, tapioca flour, brown sugar, salt, cinnamon, and nutmeg in a medium bowl. Add the melted butter and stir until large clumps form. Set aside.
In a large mixing bowl, cream the softened butter and brown sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
In a separate bowl, whisk together the sweet rice flour, sorghum flour, oat flour, tapioca flour, baking powder, baking soda, and salt.
In a small bowl, stir together the sour cream and vanilla.
Add half the dry ingredients to the butter mixture and mix until combined. Add the sour cream mixture and mix again. Add the remaining dry ingredients and beat just until the batter is smooth and fluffy.
Spread a little more than half of the batter into the prepared pan.
Scatter the blueberries evenly over the batter and sprinkle with lemon zest.
Dollop the remaining batter over the berries and gently spread it to cover.
Sprinkle the streusel over the top, squeezing some of it into clumps as needed. Add a few extra blueberries on top if desired.
Bake for 45 to 55 minutes, or until golden brown and a toothpick inserted near the center comes out clean or with a few moist crumbs.
Let the cake cool completely or until just warm before removing it from the pan.
Slice and serve as is, or finish with powdered sugar or blueberry glaze if you like.

Variations

A few easy changes can make this recipe fit different tastes and occasions. Swap the blueberries for chopped rhubarb for a more tart version. You can also use a mix of blueberries and raspberries for extra color and brightness.

For a nuttier topping, try walnuts in place of pecans. If you want a little more warmth, add a pinch of extra cinnamon to the cake batter. A simple lemon glaze can also be drizzled over the cooled cake for a sweeter finish.

Frozen blueberries work well too. Add them straight from the freezer without thawing, and be prepared to add a little extra baking time.

Storage/Reheating

Store leftover coffee cake covered in the refrigerator for up to 3 days. The topping is crispiest on the day it is baked, but the cake stays moist and delicious for the next few days.

To serve leftovers, let a slice come to room temperature or warm it gently in the microwave for about 10 to 15 seconds. For a crisper top, reheat slices in a low oven for a few minutes instead of using the microwave.

FAQs

Can I use frozen blueberries?

Yes, frozen blueberries work very well in this recipe. Use them straight from the freezer without thawing so they do not bleed too much into the batter.

What pan should I use for this coffee cake?

A 9-inch round cake pan or a 9-inch springform pan works best. Lining the pan with parchment also helps the cake release easily.

Does this coffee cake taste like coffee?

No, coffee cake does not usually contain coffee. It is called coffee cake because it is meant to be served alongside coffee.

Can I make this recipe ahead of time?

Yes, you can bake it a day in advance and store it in the refrigerator. Let it come to room temperature or warm it slightly before serving.

Can I replace the pecans?

Yes, walnuts are a good substitute, or you can leave the nuts out if needed. The streusel will still be flavorful and crumbly.

What does sour cream do in the batter?

Sour cream adds moisture and richness while helping create a soft, tender crumb. Greek yogurt or crème fraîche can be used instead.

Why is my batter thick?

This batter is supposed to be fairly thick. That thickness helps support the blueberry layer and keeps the cake from becoming soggy.

Can I make this cake dairy-free?

You can experiment with dairy-free butter and a thick dairy-free yogurt, though the texture and flavor may change slightly.

How do I know when the cake is done?

The top should look golden brown, and a toothpick inserted near the center should come out clean or with a few crumbs attached.

Can I add a glaze?

Yes, a simple blueberry or lemon glaze is a great finishing touch. It adds sweetness and makes the cake feel even more special for brunch or dessert.

Conclusion

Gluten-free blueberry coffee cake with pecan streusel is the kind of bake that feels both cozy and impressive. The tender cake, juicy berries, and crisp topping make every slice satisfying, whether you serve it for breakfast, brunch, or a simple dessert.
