How to Make Blueberry Coffee Cake
Making blueberry coffee cake requires a handful of ingredients you likely already have on hand.
- Whipping Up the Streusel Topping: Using the largest slots on a cheese grater, shred frozen or very cold butter directly into the flour. Stir in brown sugar, tossing several times to make sure everything is combined.
- Making the Coffee Cake Batter: Grab a large bowl. Add in butter and sugar, beating constantly. Add egg and vanilla extract. Beat to combine. Grab a small bowl and combine flour with baking powder. In small portions and with a slow hand, gradually add flour/baking powder mixture into the egg/vanilla extract mixture, alternating with a bit of milk. Continue adding until you run out of both the flour mixture and milk.
- Add Blueberries and Streusel: Fold in your blueberries. Pour the batter into an oiled baking dish, ensuring it is well distributed. Add the streusel mixture right on top of the batter.
- Bake and Enjoy: Pop the baking dish into the oven for about an hour. To check doneness, do the “toothpick trick”. For the vast majority of baked goods, you want to ensure a toothpick inserted into the center of the cake comes out clean. This is a great indicator that it’s fully cooked. Once your cake is ready, let it cool for 10 minutes, slice, and enjoy!
Tips for the Best Blueberry Coffee Cake
Below, find the top tips for making the best blueberry coffee cake.
- Using the Right Butter. For the cake batter, you’ll want to use softened butter. This will help it mix well with the sugar. On the other hand, the streusel requires ultra-cold butter.
- Be gentle with your fresh blueberries. When adding your blueberries to the dough, be careful not to smash them. You’ll want most of your blueberries to remain whole so you get nice pockets of juice as you bite into your cake.
- Make the batter ahead of time. Since this cake doesn’t use yeast, feel free to make the batter a day ahead of time. Leave it covered overnight in the refrigerator. Add streusel topping right before baking.
- Choosing the right flour. There’s no need for fancy cake flour here. All-purpose flour is the best for this recipe, as it creates the densest coffee cake. Bob’s Redmill flour tends to be the best quality.
- Glaze the cake. This is fully optional but if you’d like to decorate your cake with a glaze, here is how to make a simple powdered sugar glaze.
Storing Blueberry Coffee Cake
- Room Temperature: Blueberry coffee cake will remain fresh at room temperature for a few days. Just make sure to store it in an airtight container on your counter.
- Refrigerating: If you still have leftovers, make sure to pop them in the refrigerator after three days.
- Freezing: You can also freeze your blueberry coffee cake by placing it in a freezer-safe plastic bag. Coffee cake will stay fresh for up to 3 months when frozen.
Reheating Tip: Whether your leftover coffee cake is frozen or refrigerated, reheat it in a conventional oven or microwave to warm it through. Just be careful to not overcook it, as it will turn rubbery and the streusel could potentially burn.
Does a blueberry cake need to be refrigerated?

What is the difference between coffee cake and crumb cake?
The difference between coffee cake and crumb cake lies in the amount of streusel. Coffee cake tends to have less, while crumb cake touts a thick topping of streusel.
Can I add frozen blueberries to cake mix?
Do not add frozen blueberries to cake mix. Frozen blueberries have a high water content that will release during the baking process and thin your batter out. Always use fresh blueberries when baking.
How do you keep a coffee cake moist?
The key to moist coffee cake is not skimping on the butter. Additionally coffee cakes comes out dry when too much flour is added. Avoid this by always using a measuring cup or spoon when portioning out your ingredients for baking. Remember: baking is science. You need to be as exact as possible to get the best results.
Can I make this without the streusel?
You can make this coffee cake without the streusel, but keep in mind that it will be more like a “sweet bread” than a cake.
