Let’s dive into what you’ll need to create this delightful coffee cake!

What you’ll need

Gather these items before getting started:

  • 2 cups all-purpose flour
  • 1 cup granulated sugar
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1/2 cup unsalted butter, softened
  • 1 cup buttermilk
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 2 cups fresh blueberries
  • 1/2 cup brown sugar
  • 1/2 cup oats
  • 1 teaspoon ground cinnamon

Don’t hesitate to substitute buttermilk with regular milk if you’re in a pinch, as it will still give you a lovely cake!

Step-by-step instructions

  1. Preheat your oven to 350°F (175°C) and grease a 9-inch round cake pan.
  2. In a large bowl, whisk together the flour, granulated sugar, baking powder, baking soda, and salt.
  3. In another bowl, cream the softened butter until smooth. Add the buttermilk, eggs, and vanilla extract, mixing until combined.
  4. Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Be careful not to overmix! Fold in the blueberries gently.
  5. In a separate small bowl, mix together the brown sugar, oats, and cinnamon for the streusel topping.
  6. Pour half of the batter into the prepared pan, sprinkle half of the streusel mixture over the top, then add the remaining batter and finish with the rest of the streusel.
  7. Bake for 45-50 minutes or until a toothpick inserted in the center comes out clean.
  8. Allow to cool slightly before serving.

After you’ve baked it, the aroma will invite everyone to the kitchen!

Best ways to enjoy it

This Blueberry Buttermilk Coffee Cake is best served warm, straight from the oven. Pair it with a dollop of whipped cream or a scoop of vanilla ice cream for a delightful dessert. If you’re planning a brunch, this coffee cake is fabulous alongside a fresh fruit salad or a light yogurt parfait. Additionally, consider serving it with coffee or tea for a lovely afternoon treat that everyone will adore.

How to store Blueberry Buttermilk Coffee Cake

Storing any leftover cake is simple. You can keep it in an airtight container at room temperature for up to 3 days. For longer storage, wrap it tightly and freeze it for up to 2 months. Remember to allow it to cool completely before wrapping it to prevent moisture buildup. Defrost overnight in the fridge when you’re ready to enjoy it again!

Helpful cooking tips

For the best results, try to use freshest blueberries possible, as they make all the difference in flavor! If you choose to use frozen blueberries, make sure to thaw and drain them first to prevent excess moisture in your cake. Lastly, for an extra flavor twist, consider adding a dash of lemon zest to the batter—this brightens the cake beautifully.

Creative twists

Feel like experimenting? You can add nuts for a crunchy texture or swap some of the blueberries for raspberries or cranberries to create a mixed berry coffee cake. Alternatively, for an extra indulgent treat, you could drizzle a simple glaze over the top after baking.

Common questions

How long does it take to prepare this coffee cake?

Preparation takes about 20 minutes, and baking takes about 45-50 minutes. So, in total, you’re looking at roughly an hour for a delicious cake.

Can I substitute the buttermilk?

Yes! If you don’t have buttermilk on hand, you can use regular milk or even yogurt. Just add a teaspoon of lemon juice or vinegar to the milk to give it a tang similar to buttermilk.

How do I know when the cake is baked?

You’ll know the cake is ready when a toothpick inserted into the center comes out clean. The edges might be golden brown as well, adding to the visual appeal of the cake!
