Egg
Vanilla extract

Mix until smooth and fully incorporated.

Step 5: Make the Batter

Gradually add the flour mixture, alternating with the milk.

Pro Tips & Cooking Secrets

Use room-temperature butter for a lighter, fluffier cake batter.
Toss the blueberries with a teaspoon of flour before folding them into the batter to help prevent them from sinking.
Do not overmix the batter after adding the flour or the cake may become dense.
Cut the butter into the streusel while it’s cold to create crisp, buttery crumbs.
Fresh blueberries provide the best texture, but frozen blueberries work well without thawing.
Check the buckle around the 35-minute mark since oven temperatures vary.
Let the cake cool slightly before slicing so it holds together better.
Add a little lemon zest to the batter for extra freshness.
Store leftovers tightly covered to maintain moisture.
Warm individual slices in the microwave for about 15 seconds before serving to refresh the buttery texture.

Serving Suggestions

This Blueberry Buckle is incredibly versatile and can be enjoyed throughout the day. Serve it warm with a scoop of creamy vanilla ice cream for a comforting dessert that’s perfect after dinner. A generous dollop of freshly whipped cream also complements the juicy blueberries and buttery streusel beautifully.

For breakfast or brunch, pair a slice with hot coffee, cappuccino, or tea. The lightly sweet cake makes an excellent morning treat without being overly rich. It also pairs wonderfully with Greek yogurt and fresh berries for a more balanced breakfast.

Hosting friends or family? Arrange slices on a dessert platter with fresh blueberries, mint leaves, and a light dusting of powdered sugar for an elegant presentation. During the holidays, serve it alongside cinnamon-spiced coffee or hot chocolate for a cozy seasonal dessert everyone will love.

How to Store Blueberry Buckle With Brown Sugar Topping

Store leftover Blueberry Buckle in an airtight container at room temperature for up to 2 days.
