What You Need to Make This Recipe
Brown sugar — this gives the streusel a caramel-like flavor. Butter — I recommend using unsalted butter as the salt content in salted butter is inconsistent between different brands. Flour — you will need flour for both the streusel and coffee cake, so make sure you have enough on hand. You don’t need anything fancy, just all-purpose flour. Baking powder — this blueberry coffee cake batter is dense, but the baking powder helps it rise. Make sure it is fresh and not expired! Blueberries — you can use fresh or frozen blueberries. If you’re using frozen blueberries, do not thaw. If using frozen blueberries, keep in mind that they add more moisture to the coffee cake, making the cake softer and may take an extra minute or so to bake. Vanilla extract — have you tried my homemade vanilla extract? It’s perfect for adding a subtle sweetness to the cake. Milk — I recommend using whole milk to add the most moisture, richness, and flavor.
How to Make Blueberry Coffee Cake
In a large mixing bowl or the bowl of a stand mixer fitted with the paddle attachment, combine the butter, sugar, and lemon zest. Beat on high speed until light and fluffy, about 4 minutes.
Add the eggs, one at a time, beating until each is fully incorporated. Stop occasionally and scrape down the bowl. Beat in the vanilla.
Whisk together the flour, baking powder, and salt. Add a third of the flour mixture to the butter mixture with the mixer on low speed. Pour in half of the milk, beating until just incorporated. Repeat, alternating with the remaining milk and flour mixture.
Fold in blueberries.
Spread the batter into a buttered 9-inch square baking pan.
Whisk together the brown sugar, flour, cinnamon, and salt in a medium mixing bowl. Add the butter. Using a fork or your fingers, incorporate the butter into the dry mixture until a crumbly texture forms. Sprinkle the top of the batter with streusel topping. Bake for 55 minutes, then let cool for at least 15 minutes before slicing and serving.
Pro Tips for Making This Recipe
The butter should be soft enough to incorporate into the rest of the streusel topping effortlessly. It’s key for a crumbly, clumpy crumble topping. Careful not to over mix the streusel topping, or it may become paste-like in texture. You want there to be some crumbly texture to the topping of your blueberry coffee cake. The streusel topping gets toasty and brown. If you prefer it less toasty, cover the top of the coffee cake with foil at the 40-minute mark. Make sure to measure your flour correctly. I highly recommend always using a scale to measure. However, if you don’t have a scale, be sure to fluff your flour with a spoon and then spoon it into your cups before leveling it off with a knife. This method is the best way to measure flour without overpacking the measuring cup. When adding the blueberries, use a spatula to fold them in gently. As the batter is quite thick, you don’t want to break apart the blueberries with the mixer. You should bring ingredients out of the fridge, such as eggs and milk, to room temperature. It’s much easier for ingredients to incorporate when they’re at room temperature. Swap with lime zest if you don’t have a fresh lemon to zest!
Can I make this ahead of time?
If you want to start your morning with a fresh slice of blueberry coffee cake, you can make the batter as instructed and pour it into a buttered pan the night before. Cover and store in the refrigerator. Remove from refrigerator and bring to room temperature for around 30 minutes before adding the streusel topping and baking. This method does not work if you use frozen blueberries as you do not want the berries to thaw in the batter.
How do I store leftover coffee cake?
This cake keeps for up to a week in the refrigerator. Make sure to wrap it tightly or transfer it to an airtight container. Warm up the coffee cake in the microwave or oven before serving.
Can I freeze this?
This blueberry coffee cake recipe is freezer-friendly! To freeze, allow the cake to cool to room temperature before wrapping it tightly with plastic wrap and then in a layer of tin foil. Store for up to 2 months. When ready to eat, thaw in the fridge overnight, bring to room temperature, or reheat in the oven or microwave.
