Blueberry Crumb Cake: The Ultimate Guide
If you’re looking for a nostalgic, crowd-pleasing bake that highlights the juicy freshness of blueberries and the comfort of a buttery, crumbly topping, look no further than blueberry crumb cake. With layers of tender cake, bursts of blueberries, and an irresistible sweet streusel, this classic treat is ideal for breakfast, coffee breaks, or dessert. In this comprehensive guide, you’ll learn everything from ingredients and step-by-step baking instructions to expert tips and answers to common questions.
Why This Blueberry Crumb Cake Stands Out
Blueberry crumb cake perfectly merges a moist, buttery cake with the natural sweetness of fresh blueberries and a golden, cinnamon-kissed topping. The contrasting textures—soft crumb and crunchy streusel—make each bite satisfying and memorable. The cake is highly adaptable; it is just as delicious served warm with a pat of butter for breakfast as it is paired with a scoop of vanilla ice cream for dessert.
What Makes a Great Crumb Cake?
- Light, fluffy base that cradles the berries without becoming soggy.
- Even distribution of juicy blueberries for bursts of fruit in every bite.
- A buttery, slightly crunchy crumb topping made from simple pantry staples.
- Simple preparation—no special baking skills required.
Blueberry Crumb Cake Ingredients
Here’s what you’ll need to make the classic blueberry crumb cake:
For the Cake:
- 2 cups all-purpose flour
- 2 1/4 teaspoons baking powder
- 1/2 teaspoon salt
- 5 tablespoons unsalted butter, softened
- 3/4 cup sugar
- 1 large egg
- 1/2 teaspoon vanilla extract
- 3/4 cup whole milk
- 2 cups fresh blueberries
- Nonstick baking spray (for the pan)
- Softened butter, for serving (optional)
For the Crumb Topping:
- 6 tablespoons unsalted butter
- 1/2 cup plus 2 tablespoons sugar (divided for extra topping after baking)
- 1/2 teaspoon cinnamon
- 1/2 cup all-purpose flour
- 1/4 teaspoon salt
Optional: Add 1/2 cup finely chopped pecans to the topping for extra crunch and flavor.
Step-by-Step Blueberry Crumb Cake Recipe
Step 1: Prep Your Pan and Oven
Preheat the oven to 350°F (175°C). Grease a 13-by-9-inch baking pan thoroughly with nonstick baking spray, ensuring the cake comes out smoothly later.
Step 2: Make the Cake Batter
- In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
- Using an electric mixer, cream butter and sugar together until light and fluffy. This creaming step aerates your batter, setting the stage for a tender cake.
- Add the egg and vanilla extract, mixing until well combined and smooth in texture.
- With the mixer on low speed, alternate adding the flour mixture and whole milk into the butter mixture. Begin and end with the flour, mixing only until just incorporated to avoid overdeveloping gluten (which could make the cake tough).
- Gently fold in the blueberries, taking care not to crush them—this helps prevent the batter from turning blue or purple.
Step 3: Make the Crumb Topping
- In a separate bowl, combine the butter (cut into chunks), 1/2 cup of sugar, cinnamon, flour, and salt.
- Using a pastry cutter or two knives, cut the ingredients together until the mixture resembles damp, coarse sand with a few larger clumps. If using nuts, stir them in at this point.
Tip: A pastry cutter gives the crumb topping the ideal consistency. The two-knife method works in a pinch, but can be less consistent.
Step 4: Assemble the Cake
- Pour the batter into your prepared pan, smoothing the top with a spatula.
- Sprinkle the crumb topping evenly over the batter, covering the entire surface for even crunch and flavor in every bite.

Step 5: Bake
- Bake in the preheated oven for 40 to 45 minutes. The cake should be golden brown, and a toothpick inserted in the center should come out clean or with a few moist crumbs attached (avoid hitting a blueberry for a true test).
- Remove from oven and immediately sprinkle the remaining 2 tablespoons of sugar over the hot cake for a delicate, sweet crunch.
Step 6: Cool and Serve
- Let the cake cool in the pan for at least 20 minutes before slicing. This helps set the crumb and prevents the cake from falling apart.
- Serve warm with a pat of softened butter, or cool completely for neater slices. Coffee, tea, or a scoop of ice cream make fine companions.
Expert Tips for Perfect Blueberry Crumb Cake
- Fresh blueberries work best for firm, juicy bursts. Frozen berries can be used (no need to thaw), but lightly toss them in a little flour to prevent excess moisture and sinking.
- Do not overmix the batter after adding flour; gentle folding leads to a more tender crumb.
- Customization: Pecans or walnuts add richness to the crumb. A touch of lemon zest brightens the cake and complements the berries.
- For easy cleanup: Line your baking pan with parchment, leaving extra on the sides to lift the cake out.
- Storage: Wrap leftovers tightly; cake will remain fresh at room temperature for up to 2 days or refrigerated for 4 days. Briefly warm slices before serving for best flavor.

Baking FAQs
Can I use frozen blueberries?
Yes. Use them straight from the freezer and toss in a tablespoon of flour before adding to the batter. This helps prevent them from sinking and reduces purple streaks in your cake.
How do I store blueberry crumb cake?
Wrap the cake tightly in plastic wrap or foil. Store at room temperature for up to 2 days, or refrigerate for up to 4 days. To reheat, microwave individual slices for 15–20 seconds.
Can I make crumb cake in advance?
Absolutely. Blueberry crumb cake can be baked up to a day ahead. Cool completely and store, tightly wrapped. For best results, add the final sugar sprinkle just after baking to keep the crust crisp.
Why is my crumb topping sinking or merging into the cake?
A crumb topping that’s too wet will absorb into the batter rather than remain crumbly. Ensure the butter is cut in—not melted—and use a light hand when sprinkling the topping over the batter.
Is this cake sweet enough for dessert?
Yes. While not cloyingly sweet, the additional sugar sprinkle at the end ensures the cake doubles beautifully as a dessert. For a more decadent treat, serve with whipped cream or ice cream.
Can I add spices or other fruits?
A touch of nutmeg or allspice in the batter warms up the flavor profile. Swap in other berries or mix for a “berry medley” take on the cake.
Pro Tips, Tricks, and Troubleshooting
- Room Temperature Ingredients: Butter, eggs, and milk at room temperature blend more easily and create a uniform batter.
- Check Doneness: Every oven is different; start checking a few minutes before the suggested bake time. Look for golden edges and a center that springs back lightly under a fingertip.
- Lining the Pan: For easy removal, line the baking pan with parchment with an overhang. This also creates cleaner slices.
- Low-Fat Substitutions: You may use low-fat milk, though the cake will be less rich. For a dairy-free version, substitute with a plant-based milk and vegan butter.
