The warm scent from the oven is irresistible when I bake this moist, tender Blueberry Coffee Cake. It’s simple to prepare and makes a perfect breakfast or dessert.
The cake batter uses sour cream to keep the crumb soft and moist. Fresh blueberries add a burst of natural sweetness while lemon zest brightens the flavor. This blueberry buckle is lightly sweet, so it’s perfectly acceptable to enjoy a slice with your morning coffee.

I first tried this recipe years ago after borrowing one of Ina Garten’s cookbooks. True to form, it became a favorite. At first my husband preferred a classic cinnamon streusel coffee cake without fruit, but once he tasted this blueberry version he asked me to make it every summer when blueberries are abundant.

How To Make Blueberry Coffee Cake
-
Preheat the oven and prepare a 9-inch baking pan by buttering and flouring it.
-
Cream the butter and sugar until pale and fluffy. Proper creaming adds air for a lighter cake.
-
Add the eggs one at a time, mixing after each. Stir in vanilla, lemon zest and sour cream.
-
Sift together flour, baking powder, baking soda, and salt; add to the batter on low speed until just incorporated.
-
Gently fold in the blueberries so they distribute evenly without breaking.
-
Spread the batter into the prepared pan and top with the crumb topping.
-
Bake until a toothpick inserted in the center comes out clean or with a few moist crumbs, about 40–50 minutes depending on your oven. Cool before serving.





How To Make the Crumb Topping
-
Combine flour, sugar, lemon zest and butter in a small bowl.
-
Use a pastry blender, fork or your fingers to cut the butter into the dry ingredients until coarse crumbs form.
-
Scatter the crumb mixture evenly over the cake batter and bake as directed.

Is This A Coffee Cake or a Buckle?
Terminology for fruit desserts can be confusing. A buckle is an old-fashioned cake packed with fruit and finished with a streusel. This recipe fits both descriptions, so you can call it a coffee cake or a blueberry buckle.
How Is Best to Store This Coffee Cake?
-
At room temperature: keep in an airtight container for up to 3 days.
-
Refrigeration: after cooling, store in an airtight container for up to a week.
-
Freezing: wrap tightly in plastic wrap, place in an airtight container or freezer bag, and freeze for up to 2 months.
Coffee Cake Recipe Tips
-
Measure ingredients precisely—baking is a science.
-
The batter is intentionally thick so the blueberries stay suspended; coating them with flour isn’t necessary.
-
Use room-temperature eggs so they emulsify properly with the creamed butter and sugar.
-
Add eggs one at a time and mix only until incorporated to avoid overworking the batter.
-
Check doneness with a skewer or toothpick; a few moist crumbs clinging to it indicate a well-baked, moist cake.

Can I make this recipe with frozen blueberries?
Yes. You can fold frozen blueberries into the batter without thawing; they may release more juice while baking but still work well.
Can I make this coffee cake ahead of time?
Yes. It’s delicious warm, but it can be refrigerated or frozen and reheated when needed.
Can I add a glaze to this coffee cake?
Absolutely. A simple lemon glaze made from powdered sugar and lemon juice complements the cake nicely.
