Step-by-Step Instructions for Blueberry Streusel Coffee Cake

Making this Blueberry Streusel Coffee Cake is a simple process that takes less than an hour to prep and bake. Follow these easy steps to create your new favorite treat.

1. Prepare the Streusel

In a small mixing bowl, combine the flour, brown sugar, ground cinnamon, and a pinch of salt. Stir until everything is well mixed. Then, drizzle in the melted butter and use a fork or your hands to mix until the streusel becomes crumbly. Set aside.

2. Make the Coffee Cake Batter

In a separate large mixing bowl, cream together the room-temperature butter and sugar using an electric mixer (or whisk) until light and fluffy. This usually takes about 2-3 minutes.

Add in the egg and vanilla extract and continue mixing until fully combined. Then, add the sour cream and milk, mixing until smooth.

In a separate bowl, whisk together the all-purpose flour, baking powder, and salt. Gradually add the dry ingredients to the wet mixture, mixing just until incorporated. Be careful not to overmix.

Gently fold in the blueberries using a spatula. This will help distribute the fruit evenly without smashing the berries.

3. Assemble the Coffee Cake

Preheat your oven to 350°F (175°C). Grease a 9-inch round cake pan or line it with parchment paper for easy removal. Spoon the batter into the prepared pan and spread it out evenly.

Sprinkle the streusel topping generously over the cake batter. Don’t worry if it looks a little uneven— the streusel will create a delicious, crumbly top as it bakes.

4. Bake the Coffee Cake

Place the cake in the preheated oven and bake for 40-45 minutes, or until a toothpick inserted into the center of the cake comes out clean (or with just a few moist crumbs). The streusel should be golden brown and slightly crisp.

Once baked, remove the cake from the oven and allow it to cool in the pan for about 10 minutes. Then, transfer it to a wire rack to cool completely.

5. Prepare the Glaze

While the cake is cooling, prepare the glaze by whisking together powdered sugar, milk, and vanilla extract in a small bowl. Start with 1 tablespoon of milk and add more if you want a thinner glaze. Drizzle the glaze over the cooled coffee cake just before serving for a sweet finish.

How to Serve Blueberry Streusel Coffee Cake

This coffee cake is perfect for serving at breakfast or brunch gatherings. But it’s also a fantastic dessert to have on hand for whenever you want a sweet treat.

Here are some serving ideas:

• With Coffee or Tea: Pair this cake with a hot cup of coffee or a pot of your favorite tea. The sweetness of the cake complements both beverages beautifully.
• For Breakfast: Serve it warm with a dollop of whipped cream or a side of Greek yogurt for extra protein.

Storing Blueberry Streusel Coffee Cake

If you have leftovers (though I doubt you will!), here’s how to store them:

• Room Temperature: Store the coffee cake in an airtight container at room temperature for up to 2 days. This will keep the cake moist and fresh.
• Refrigeration: For longer storage, you can refrigerate the coffee cake for up to 5 days. Make sure it’s in an airtight container to prevent it from drying out.
