Fresh farm eggs are my go-to breakfast, but I love whipping up an easy coffee cake when I'm craving something sweet. And this blueberry sour cream coffee cake is at the top of my list. My kids and husband love it just as much for an everyday breakfast.

Blueberry coffee cake is tender and moist, complete with a layer of cinnamon streusel filling, blueberries, crunchy topping, and a simple glaze for the finishing touch! This cake is baked in a square pan, making it the perfect size for a family breakfast with some leftovers (or perhaps a late night treat!). It’s sure to be a hit (and it’s our secret how easy it is to prepare!).

If you have extra blueberries left over, you might also enjoy trying these lemon blueberry cookies, whole wheat blueberry muffins, or these perfect sized blueberry hand pies.

What Makes This The Best Blueberry Coffee Cake?

This coffee cake has four components. Sounds complicated? I promise you, it’s not. It’s a simple coffee cake to make for a delicious treat any time of day. Here’s why it’s soooo good: 

1. Streusel topping: Buttery and sweet streusel quickly comes together and adds a lovely swirl to the center of the cake with a beautiful, crunchy topping.
2. Moist & tender cake: Sour cream is the key to this irresistible, moist, and light cake.
3. Blueberries: Sweet blueberries add the perfect pop of flavor for a delicious twist to a classic.
4. Simple glaze: Four basic ingredients create the perfect finish for this blueberry sour cream coffee cake. The glaze adds a beautiful touch and a sweet complement to the crunchy streusel.

Ingredients You'll Need

• All-purpose flour: Nothing fancy here. Regular, all-purpose flour will do the trick. I always use unbleached and unbromated flour (King Arthur flour is my go-to!).
• Sugar: You’ll need both brown sugar (light or dark) and granulated sugar for the streusel topping and the cake.
• Cinnamon: Adds a warm, spice flavor to your streusel topping and glaze. I go heavy and use 2 heaping teaspoons for the topping. Depending on your preference, adjust the amount accordingly.
• Salt: Enhances the flavors of the other ingredients in the batter.
• Unsalted butter: You’ll need one stick of butter at room temperature. If substituting with salted butter, reduce the salt to ¼ teaspoon.
• Leaveners: A combo of baking powder and baking soda makes the perfect tender cake that rises evenly.
• Eggs: You’ll need two eggs for this recipe (I suggest large eggs for all my recipes). Bring the eggs to room temperature for a smooth batter.
• Vanilla: Splurge on a good quality pure vanilla extract! It’ll make a difference.
• Sour Cream: Use full-fat sour cream for the best flavor and texture (make sure it’s at room temperature). I don’t recommend substituting it with milk or buttermilk (it will affect the texture of your cake!), but you can use Greek yogurt.
• Blueberries: We’re using frozen blueberries (no need to thaw!). Feel free to swap them with fresh blueberries.
• Glaze ingredients: Powdered sugar plus any milk you have on hand will do!

How To Make Blueberry Sour Cream Coffee Cake

Before you begin: Preheat the oven to 350°F/375°C. Line an 8x8-inch square baking pan with parchment paper.

Make the glaze: Stir the powdered sugar with the milk and drizzle over the cake.

The Best Pans For Baking Coffee Cake

There are so many baking pans to choose from. But to help narrow down the options, here’s what I recommend using for baking this blueberry coffee cake:

1. Size: an 8x8-inch square pan is my go-to. It creates a lovely thick-layer cake, but you can also use a 9x9-inch square pan for a thinner cake (and slightly less baking time). Alternatively, use a 9-inch springform pan for a beautiful round presentation and easy removal (or a regular 9-inch cake pan).
2. Material: Choose a metal or glass baking pan for an evenly baked cake (a ceramic pan will take longer). Avoid using a dark-coated metal pan, or it will bake too quickly and cause the edges to overbake.

Don't Forget These Tips For The Best Blueberry Coffee Cake

Coffee cake is quick and easy to make (just like this cinnamon roll coffee cake!). Mixing pantry staples for this delicious breakfast treat only takes a few simple steps. But the difference between an ok coffee cake and a GREAT coffee cake is in the details.

So here’s how you get a fluffy, moist, and tender cake:

1. Pay attention to ingredient temperature: Pop the streusel topping in the fridge to firm up while making the cake, and use room temperature ingredients for the batter.
2. Don’t overmix the batter: This is key to preventing a dense cake. To get a perfectly moist, tender crumb, mix the dry ingredients on LOW speed until JUST combined!
3. Check for doneness: Start checking for doneness around the 47-50 minute mark. All ovens run differently, so checking early is key! Gently press the center of the cake, if it bounces back and the streusel is golden brown, then you’re good to go!

How To Store Coffee Cake

If you have leftover coffee cake, it will stay fresh at room temperature for up to 2-3 days if stored in an airtight container. You can also store it in the fridge sealed tightly for up to a week. Make sure to let the cake cool completely before covering.

Can You Freeze This Blueberry Coffee Cake?

Absolutely! Let the cake come to room temperature before placing it in a freezer-safe bag or container. You can freeze it for up to 3 months. When you're ready to serve it, thaw the cake in the refrigerator overnight, then let it come to room temperature before adding the glaze and serving it.
