Imagine a crisp morning where the sun is just peeking over the horizon, and the smell of freshly brewed coffee fills the kitchen. There’s a special kind of magic in those quiet moments, especially when a warm, tender coffee cake is involved. Blueberry Streusel Coffee Cake isn’t just a treat—it’s a slice of comfort, a nostalgic nod to slow mornings and family gatherings.

This cake reminds me of summers spent at my grandmother’s house. She always had some kind of baked good waiting on the counter, but when blueberries were in season, it was guaranteed there would be a blueberry coffee cake tucked under a glass dome. She believed in starting the day with a little sweetness—and who could argue with that?

The streusel topping was always my favorite part—golden, buttery, and just the right amount of crunchy. Paired with bursts of juicy blueberries and a tender, moist crumb, this coffee cake is a timeless treasure. It’s a perfect companion to a steaming mug of coffee, a cozy brunch centerpiece, or a special afternoon treat.

This recipe has all those old-fashioned cozy vibes, but it’s easy enough for even a beginner baker to pull off. Let’s make something delicious together!

HOW TO MAKE Blueberry Streusel Coffee Cake:

STEP-BY-STEP INSTRUCTIONS:

1. Prepare Your Baking Dish:
Preheat your oven to 350°F (176°C) and grease a 9×13-inch baking dish. I like to line it with parchment paper too, just to make lifting the cake out a little easier later on.

2. Mix the Dry Ingredients:
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set it aside—you’ll be folding it in later.

3. Cream the Butter, Oil, and Sugar:
In a large mixing bowl, beat the butter, oil, and sugar together until the mixture is light and fluffy. This step builds the base for a wonderfully tender cake. Don’t rush it; give it a good few minutes.

4. Add Eggs and Flavor:
Mix in the eggs one at a time, making sure each is fully incorporated before adding the next. Stir in the vanilla extract. By now, your batter should smell heavenly.

5. Alternate Adding Flour Mixture and Sour Cream:
Add half of the dry ingredients, then mix until just combined. Add the sour cream, mixing it in gently, and then add the rest of the flour mixture. Don’t overmix—just stir until there are no big flour streaks left.

6. Fold in the Blueberries:
Carefully fold the blueberries into the batter. Try to be gentle so you don’t smash them—you want those bright, juicy pops in every bite.

7. Make the Streusel:
In a small bowl, combine the flour, brown sugar, and cinnamon. Pour in the melted butter and mix it with a fork until crumbly. The smell alone will make you want to sprinkle it on everything!

8. Assemble and Bake:
Spread the batter evenly into the prepared dish, then sprinkle the streusel topping all over. It might seem like a lot, but trust me, you want every bite covered!
Bake for 35–40 minutes, or until a toothpick inserted into the center comes out clean. Your kitchen will smell absolutely incredible.

9. Cool and Serve:
Let the coffee cake cool for at least 10–15 minutes before slicing. It’s perfect warm, but just as delicious at room temperature.

HELPFUL TIPS:

• Fresh vs. Frozen Blueberries: If you’re using frozen berries, don’t thaw them first. Toss them in a little flour before folding into the batter to keep them from sinking.
• Sour Cream Substitute: Greek yogurt works in a pinch if you don’t have sour cream.
• Extra Crunchy Streusel: For even more texture, sprinkle a few chopped nuts into the streusel topping.
• Even Baking: Make sure to spread the batter evenly in the pan to avoid uneven cooking.

FREQUENTLY ASKED QUESTIONS:

Can I make this coffee cake ahead of time?
Absolutely! It actually tastes even better the next day once the flavors have had time to meld.

Can I freeze Blueberry Streusel Coffee Cake?
Yes! Wrap individual slices tightly in plastic wrap, then foil, and freeze for up to 2 months. Thaw at room temperature when ready to enjoy.

Can I use other berries?
Totally! Raspberries, blackberries, or a mix would all work beautifully.

How do I prevent the streusel from sinking into the cake?
Make sure your streusel mixture is crumbly and your batter isn’t too wet. Also, try not to press the streusel into the batter—just gently sprinkle it over the top.

STORAGE INSTRUCTIONS:

Store your blueberry coffee cake in an airtight container at room temperature for up to 3 days. If you want it to last longer, pop it into the fridge where it’ll stay fresh for about 5 days. Just warm up a slice before eating to bring back that just-baked coziness.
