Fresh Blueberry Coffee Cake Recipe
This blueberry sour cream coffee cake is an anytime treat — just like classic rhubarb coffee cake or a cinnamon streusel coffee cake. It’s quick to assemble: the batter combines pantry staples with sour cream for extra moisture, then the streusel with chopped pecans adds a crunchy finish.
Using fresh blueberries gives the best texture and flavor, but frozen berries will work if thawed and patted dry first. The recipe below includes a simple optional glaze to add a pretty finishing touch.

Ingredients Needed
This recipe uses common pantry items and fresh blueberries. Refer to the ingredient list below for exact amounts.
- All-purpose flour – measure by spooning into the cup and leveling for accuracy.
- Baking powder & baking soda – both help the cake rise.
- Salt – enhances overall flavor.
- Unsalted butter – softened for the cake; cold and cubed for the streusel.
- Granulated and brown sugar – sweetness for both cake and streusel.
- Eggs – add structure and richness.
- Vanilla extract – a small amount brightens the batter and glaze.
- Sour cream – keeps the cake moist and adds subtle tang; Greek yogurt may be substituted.
- Whole milk – optional 1/4 cup for a softer crumb.
- Fresh blueberries – about 1 1/2 cups; thawed and dried if using frozen.
- Streusel – flour, granulated and brown sugar, cinnamon, cold butter, chopped pecans, and a pinch of salt.
- Glaze (optional) – powdered sugar, a splash of milk, and a touch of vanilla.
How To Make Blueberry Coffee Cake
A quick overview of the steps follows. Full ingredient measurements and a printable recipe card are included below.
- Preheat and prep. Heat the oven to 350°F and grease an 8×8-inch square pan.
- Combine dry ingredients. Whisk flour, baking powder, baking soda, and salt in a bowl.
- Cream butter and sugar. Beat softened butter with sugar until light and fluffy. Add eggs one at a time, then vanilla.
- Mix batter. Alternate adding the dry ingredients and sour cream, finishing with milk if using. Fold in the blueberries gently to avoid breaking them.
- Make streusel. Mix flour, brown and granulated sugar, cinnamon, and salt. Cut in cold butter until crumbly, then stir in chopped pecans. Sprinkle evenly over the batter.
- Bake. Bake 45–55 minutes at 350°F, until a toothpick in the center comes out clean and the streusel is golden.
- Cool and glaze. Cool completely on a wire rack. Whisk powdered sugar with milk and vanilla for a drizzle; thin with more milk if needed, then pour over the cooled cake.
Tips & Variations
- Add lemon. Stir in lemon zest to the batter for a fresh citrus note.
- Swap berries. Use raspberries, blackberries, or chopped strawberries in place of blueberries.
- Change the nuts. Substitute walnuts or almonds for pecans, or omit nuts for a nut-free version.
- Make the streusel ahead. Prepare and refrigerate the streusel, then sprinkle it on just before baking to save time.
Proper Storage
- Room temperature: Store in an airtight container for 1–2 days.
- Refrigerator: Keeps 5–7 days when covered and chilled.
- Freezer: Wrap tightly and freeze whole or in slices for 2–3 months; thaw before serving.
