Key Ingredients
For the cake: All-purpose flour creates the perfect tender crumb, while sour cream adds richness and keeps everything incredibly moist. Butter brings flavor and structure, and fresh blueberries provide pops of sweetness throughout.
For the streusel: Cold butter is essential for creating those coveted crumbly chunks. Brown sugar adds caramel notes, cinnamon brings warmth, and a touch of flour holds everything together.
Pantry staples: Eggs bind the batter, vanilla enhances flavor, and baking powder gives a gentle lift. A pinch of salt balances the sweetness and makes all the flavors shine.
How to Make It
Start by preparing your streusel topping so it’s ready when you need it. Mix the dry ingredients, then cut in cold butter until the mixture resembles coarse crumbs—this creates those perfect clumps.
For the cake batter, cream butter and sugar until light and fluffy, then beat in eggs and vanilla. Alternate adding the dry ingredients and sour cream, mixing just until combined to avoid tough cake.
Gently fold in the blueberries, pour into your prepared pan, and sprinkle generously with streusel. Bake until golden and a toothpick comes out clean—your kitchen will smell absolutely heavenly.

Notes
- Storage: Cover tightly and store at room temperature for up to 3 days, or refrigerate for up to 5 days.

Serving Suggestions
This coffee cake shines at room temperature but is absolutely divine when slightly warm. Serve it with a hot cup of coffee or tea for the classic pairing that never disappoints.
Add a dollop of whipped cream or a dusting of powdered sugar for an extra-special presentation. For brunch gatherings, pair it with fresh fruit and yogurt for a complete spread.
Leftovers make an excellent afternoon snack or even a sweet breakfast-for-dinner option. Toast individual slices lightly for a crispy edge that brings new life to day-old cake.
Storage Tips
Keep this cake covered at room temperature for up to three days—the streusel stays surprisingly crisp. For longer storage, wrap tightly and refrigerate for up to five days.
The cake freezes beautifully for up to three months. Wrap individual slices in plastic wrap, then store in a freezer bag for grab-and-go breakfast options.
To reheat, warm slices in a 300°F oven for 5-7 minutes or microwave for 20-30 seconds. The streusel softens slightly when reheated but the cake itself stays wonderfully moist.
Frequently Asked Questions
Can I use frozen blueberries instead of fresh?
Absolutely! No need to thaw frozen blueberries just toss them with a tablespoon of flour before folding into the batter. This prevents excess moisture and color bleeding. Your cake will turn out just as delicious.
Why is my streusel topping not crumbly?
The butter needs to be cold for perfect crumbly texture. If your butter is too soft, the mixture will become paste-like instead of forming those desirable clumps. Pop it in the freezer for 5 minutes if needed before cutting it into the dry ingredients.
Can I make this coffee cake the night before?
Yes! This cake actually improves overnight as the flavors meld together. Bake, cool completely, then cover tightly and store at room temperature. The texture remains perfect and it’s ready to serve for morning guests.
