Blueberry Crumble Cake Recipe

Blueberry Crumble Cake Recipe

There’s something undeniably comforting about a slice of Blueberry Crumble Cake. It combines the best of two worlds — a moist, buttery cake filled with sweet blueberries, and a golden, crunchy crumble topping that adds texture and flavor with every bite.

This cake is ideal for casual gatherings, family breakfasts, or an afternoon tea treat. It’s rustic yet refined, and the tartness of the berries beautifully balances the sweet, spiced crumb. Plus, it’s easy to make and can be prepped ahead of time. Serve it warm with a dollop of whipped cream or a scoop of vanilla ice cream for the ultimate indulgence.

Ingredients

For the Cake:

• 1 ½ cups all-purpose flour
• 1 tsp baking powder
• ½ tsp baking soda
• ¼ tsp salt
• ½ cup unsalted butter, softened
• ¾ cup granulated sugar
• 2 large eggs
• 1 tsp vanilla extract
• ½ cup sour cream or plain yogurt
• 2 cups fresh or frozen blueberries (tossed with 1 tbsp flour)

For the Crumble Topping:

• ½ cup all-purpose flour
• ⅓ cup brown sugar
• ½ tsp cinnamon
• Pinch of salt
• ¼ cup unsalted butter, cold and cubed

Optional Glaze (for drizzling):

• ½ cup powdered sugar
• 1–2 tbsp milk
• ¼ tsp vanilla extract

How to Make Blueberry Crumble Cake

Step 1: Prep the Oven and Pan

Preheat your oven to 350°F (175°C).

Grease and flour an 8-inch square or round baking pan, or line it with parchment paper.

Step 2: Make the Crumble Topping

In a bowl, mix flour, brown sugar, cinnamon, and salt.

Cut in the cold butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs.

Refrigerate the topping while preparing the batter to keep it firm.

Step 3: Make the Cake Batter

In a medium bowl, whisk together the flour, baking powder, baking soda, and salt.

In a large bowl, beat butter and sugar until light and fluffy (about 3 minutes).

Add eggs one at a time, mixing well after each addition. Stir in vanilla extract.

Mix in the sour cream until smooth.

Add the dry ingredients to the wet ingredients and mix until just combined.

Gently fold in the blueberries (tossed in flour to prevent sinking).

Step 4: Assemble and Bake

Pour the batter into the prepared pan and smooth the top.

Sprinkle the chilled crumble topping evenly over the batter.

Bake for 40–45 minutes, or until a toothpick inserted into the center comes out clean and the crumble is golden brown.

Allow to cool in the pan for 15–20 minutes before slicing.

Step 5: Optional Glaze

Mix powdered sugar, milk, and vanilla until smooth.

Drizzle over the cooled or slightly warm cake for a sweet finish.

Chef’s Notes

Fresh vs. Frozen Blueberries: Both work well. If using frozen, do not thaw before folding into the batter to prevent color bleeding.

Sour Cream Substitution: Plain yogurt or buttermilk can be used for similar moisture and tang.

Crumble Tip: Keep the butter cold when mixing the crumble — it ensures a crisp, bakery-style topping.

Flavor Boost: Add lemon zest to the batter or crumble for a fresh twist.

Serving Suggestion: Serve slightly warm with whipped cream, crème fraîche, or vanilla ice cream.

Frequently Asked Questions (FAQs)

1. Can I use other berries instead of blueberries?

Yes! Raspberries, blackberries, or chopped strawberries all work well. Just make sure to toss them in a little flour before adding to the batter.

2. How do I store this cake?

Store in an airtight container at room temperature for up to 2 days or in the refrigerator for up to 5 days. Reheat slices gently before serving if you like it warm.

3. Can I freeze Blueberry Crumble Cake?

Absolutely. Let the cake cool completely, wrap tightly in plastic wrap, then foil, and freeze for up to 2 months. Thaw overnight in the refrigerator before serving.

4. Can I make this as muffins?

Yes! Spoon batter into a lined muffin tin (about ¾ full), top with crumble, and bake at 350°F for 20–25 minutes. This recipe makes about 10–12 muffins.

5. Why is my crumble topping sinking into the cake?

If the crumble is too soft or warm when added, it may melt and sink. Chill the topping until firm before sprinkling it over the batter to keep it crisp and separate.
