For the Blueberry Buckle

Butter or Shortening – Adds richness and moisture to the batter. You can use either based on preference.

White Sugar – Sweetens the cake and the crumb topping.

Egg – Helps bind the batter and adds structure.

All-Purpose Flour – The base of the cake and topping. Gives the buckle its soft texture.

Baking Powder – Helps the cake rise and stay fluffy.

Salt – Balances the sweetness and enhances flavor.

Milk – Adds moisture to the batter. Whole milk works best, but any milk will do.

Fresh Blueberries – The star of the show! Juicy bursts of sweetness throughout the cake.

For the Crumb Topping

White Sugar – Adds sweetness and that classic crumble crunch.

All-Purpose Flour – Combines with butter to create a crumbly texture.

Butter (Softened) – Makes the topping rich and helps it brown beautifully.

Ground Cinnamon – Adds warm, cozy spice to the topping.

Ingredients

Cake Batter:

¾ cup white sugar
¼ cup butter or shortening
1 large egg
2 cups all-purpose flour
2 tsp baking powder
½ tsp salt
½ cup milk
2 cups fresh blueberries

Crumb Topping:

½ cup white sugar
⅓ cup all-purpose flour
¼ cup butter, softened
½ tsp ground cinnamon

Instructions

Preheat your oven to 375°F (190°C). Lightly grease an 8x8-inch baking pan.
In a large bowl, beat together the sugar, butter, and egg using an electric mixer until the mixture is light and fluffy.
In a separate bowl, whisk together the flour, baking powder, and salt.
Add the dry ingredients to the creamed mixture in two parts, alternating with the milk. Mix briefly after each addition until just combined.
Fold in the blueberries gently with a spatula. Pour the batter into the prepared pan and spread evenly.
To make the topping, combine sugar, flour, butter, and cinnamon in a small bowl. Use your fingers or a fork to mix until crumbly.
Sprinkle the topping evenly over the batter.
Bake for 30 to 40 minutes, or until a toothpick inserted in the center comes out clean.
Cool slightly before serving. Enjoy warm or at room temperature.

1. Can I use frozen blueberries instead of fresh ones?
Yes! Frozen blueberries work well. Just be sure not to thaw them before mixing into the batter, as thawing can cause bleeding and discolor the cake. Keep in mind they may release more moisture, which could result in a slightly softer texture.

2. How can I prevent the blueberries from sinking to the bottom of the cake?
Toss the blueberries with about 1 tablespoon of flour before folding them into the batter. This helps create a light coating that suspends the berries evenly and minimizes sinking as the cake bakes.

3. What should I do if I don’t have shortening for the batter?
You can use all butter in place of shortening. Butter will add a richer, more flavorful taste, while shortening typically gives a softer crumb. Either option will work—your buckle will still be delicious!

4. How do I store leftover Blueberry Buckle?
Keep leftovers in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate it and bring it back to room temperature before serving to restore the best texture and flavor.

5. Can I prepare the batter in advance?
Yes! You can assemble the batter directly in the baking pan, cover it, and refrigerate overnight. When you’re ready to bake, simply sprinkle on the crumb topping and pop it in the oven. Perfect for an easy make-ahead breakfast or brunch treat.
