Ingredients You’ll Need

For the Streusel Topping

You’ll need flour for structure, brown and granulated sugars for sweetness and caramel flavor, and cinnamon for warmth. Cold butter is the key ingredient that creates that crumbly, bakery-style topping as it bakes.

For the Cake

Dry ingredients: all-purpose flour gives stability, baking powder and baking soda provide lift, and a pinch of salt balances flavor.
Wet ingredients: butter adds richness, sugar and lemon zest create sweetness and fragrance, eggs build structure, and sour cream gives perfect moisture. Vanilla adds depth, and blueberries bring fruity bursts. Tossing berries in flour keeps them from sinking.

Ingredient Substitutions

You can use Greek yogurt instead of sour cream, vegan butter for a dairy-free option, or a gluten-free flour blend for those with sensitivities. Lime zest can replace lemon for a fun flavor change.

How to Make Blueberry Coffee Cake Step-by-Step

Prep the Pan and Oven

Preheat your oven to 350°F and line a 9×9-inch baking pan with parchment paper. This helps with easy removal and clean edges.

Make the Streusel

In a small bowl, combine flour, both sugars, and cinnamon. Cut in the cold butter using a fork or your hands until the mixture is crumbly. Keep it in the refrigerator while preparing the batter.

Prepare the Batter

In a bowl, whisk together the flour, baking powder, baking soda, and salt. In another large bowl, mix the sugar and lemon zest until sandy. Add the butter and beat until creamy and light. Next, add eggs and vanilla, mixing just until smooth. Alternate adding dry ingredients and sour cream, starting and ending with the dry mixture. Mix gently to keep the batter tender.

Add the Blueberries

Fold in the floured blueberries with a spatula. Be careful not to crush them to avoid coloring the batter.

Assemble and Bake

Spread the batter evenly into the prepared pan. Sprinkle the cold streusel evenly on top. Bake for 45 to 55 minutes, until golden brown and a toothpick comes out clean or with a few crumbs. Let the cake cool for about 20 minutes before slicing.

Expert Baking Tips

Use room temperature ingredients for the best texture. Avoid overmixing the batter so the crumb stays soft. Always coat blueberries in flour to prevent them from sinking. Keep the streusel cold until baking so it stays crumbly. Start checking for doneness at 45 minutes since oven temperatures vary. For a beautiful finish, dust the cake with powdered sugar or drizzle it with a simple lemon glaze before serving.

Storage, Freezing, and Make-Ahead Tips

Keep the cake in an airtight container at room temperature for up to three days. If you need to store it longer, refrigerate it for up to a week. For freezing, wrap individual slices in plastic wrap and freeze for up to two months. Thaw slices at room temperature or reheat in the microwave for 30 seconds to enjoy that fresh-baked taste again. It’s a great make-ahead treat for brunch or holiday mornings.

Variations to Try

Try baking this recipe in a Bundt pan and layering half the streusel in the middle for a lovely surprise. Add a lemon glaze for a citrus twist or mix in raspberries and blackberries for extra color. You can even toss in a handful of chopped nuts for crunch. Just adjust the baking time if you use a different pan size.
