🥘Ingredients
See recipe card for quantities.
For the blueberry coffee cake:
- butter- soften this at room temperature for best results; 1 stick is all you need and half of it is used in the topping
- granulated sugar
- eggs- slightly beat before adding to the bowl; using room temperature eggs makes the batter more fluid and easier to mix
- milk- I typically use skim; for a creamier cake use whole
- flour
- salt & baking powder- leavening agents
- fresh blueberries- choose plump berries for best flavor
For the buckle (streusel topping):
- butter
- granulated sugar
- flour
- cinnamon
🔪Instructions
- In a large bowl, cream ½ stick of softened butter with ¾ cup sugar.
- Beat the eggs slightly in a separate bowl and add the milk. Then add this mixture to the large bowl. Stir until well blended.
- Mix the dry ingredients for the cake; then add to the large bowl. Stir to combine.
- Gently fold in the blueberries.
- Add the cake batter to your prepared Bundt pan.
- Make the streusel by melting the butter. Mix it with the remaining flour, sugar and cinnamon. Spoon this mixture over the cake batter.
- Bake and allow to cool before serving.
Hint: To accurately measure the flour, lightly spoon it in a measuring cup and gently level off for best results.
🥣Substitutions
Blueberries: You can use frozen blueberries in this recipe. Do not defrost; simply add them frozen to the batter. (Bake time might be slightly longer with this option.)
📖Variations
Cranberry Buckle: Use 2 cups fresh or frozen cranberries instead of blueberries, along with 1 T. orange zest. For even more orange flavor, replace the milk with orange juice.
Mixed Berry Buckle: Use a combination of blueberries, blackberries and chopped strawberries to total 3 cups.
🍽Equipment
- large mixing bowl
- medium mixing bowl
- small mixing bowl
- whisk
- mixing spoons
- measuring cups
- measuring spoons
- pastry cutter
- microwavable safe dish
- 2 part metal Bundt/tube pan, or springform pan
🍶Storage
Cover cake with foil on a serving plate. Let the cake sit on your countertop. Enjoy within three days.
Freezing instructions: Wrap really well in freezer safe food packaging. The cake can be frozen for up to two months. To defrost, allow the cake to defrost overnight in your fridge. It will be a little soggy, but it will still taste amazing!
💭Top tip
When adding the dry ingredients, it's important not to overmix. Stir until just combined instead. Over stirring will affect the consistency of the eggs, and cause them overbind with the ingredients, causing a chewy cake. We beat the eggs slightly before adding for this very reason.
🤔Why is it called a buckle?
As a kid, I ate this and never thought twice about the name, but now, as an adult, I ask: why buckle? If you look closely at the top of the cake after it bakes, do you see the crevices and breaks in the delicious streusel topping?
Those crevices you see are the result of a buckle! Think about a city street in the hot summer months. What happens sometimes in intense heat? The asphalt buckles from the pressure of high temperatures and a split in the road occurs.
It's no different with the buckle in Blueberry Buckle Coffee Cake (well, minus the asphalt at least). As our delicious cake bakes, the pressure and heat (mainly from the blueberries-- those rascals!) causes the topping to crackle and buckle under pressure!
