For the Cake Batter
- All-purpose flour – Forms the structure of the cake; can substitute with gluten-free flour.

- Cinnamon – Provides warmth and depth; omit if it’s not your preference.

- Baking powder – Aids in rising the cake; don’t substitute with baking soda without adjusting the acids.
- Salt – Enhances overall flavor; essential for a balanced cake.
- Eggs (room temperature) – Help structure and moisture in the cake; aquafaba can work as a vegan substitute.

- Vegetable oil (room temperature) – Contributes to moisture; can substitute with coconut oil.

For the Lemon Glaze
- Powdered sugar – Sweet base for the glaze; can swap with coconut powdered sugar.
- Lemon juice – Infuses tanginess; fresh juice is preferable for best flavor.
This careful selection of ingredients will ensure your Blueberry Coffee Cake is mouthwateringly delicious, so let’s get baking!
Step‑by‑Step Instructions for Blueberry Coffee Cake
Step 1: Preheat Your Oven
Preheat your oven to 175ºC (350ºF) to ensure it’s ready for your Blueberry Coffee Cake. While the oven heats, prepare a 23 cm (9-inch) springform pan by lining the bottom with parchment paper. This will prevent sticking and make it easier to remove the cake later.
Step 2: Make the Crumble Topping
In a medium bowl, combine the crumble ingredients to create the topping for your coffee cake. Use your fingers or a fork to mix them together until the mixture resembles coarse crumbs, taking about 5 minutes. Set the crumble aside, allowing it to firm up while you prepare the cake batter.
Step 3: Prepare the Cake Batter
In a large mixing bowl, cream the room temperature butter and granulated sugar using an electric mixer for about 3 minutes until light and fluffy. Then, add eggs one at a time, mixing well after each addition. Gradually incorporate half of the sifted dry ingredients, then stir in the lemon zest, sour cream, vegetable oil, and vanilla until just combined.
Step 4: Incorporate Remaining Ingredients
Add the remaining dry ingredients to the batter, mixing until just combined to ensure a tender Blueberry Coffee Cake. Avoid over-mixing, which can toughen the cake. Once the batter is ready, toss your blueberries with cornstarch—this prevents them from sinking—and gently fold half of them into the mixture.
Step 5: Assemble the Cake
Pour the batter into the prepared springform pan, smoothing the top gently with a spatula. Sprinkle the remaining blueberries evenly over the batter, and then, generously distribute the crumble topping on top. This creates a beautiful layer of crunch that contrasts perfectly with the moist cake.
Step 6: Bake Your Cake
Carefully place the pan into the preheated oven and bake for 45-50 minutes. Check for doneness by inserting a cake tester or toothpick into the center; it should come out clean when your Blueberry Coffee Cake is ready. Once done, allow the cake to cool in the pan for about 10 minutes.
Step 7: Cool and Prepare the Glaze
After 10 minutes, remove the cake from the pan and transfer it to a wire rack to cool completely. While the cake cools, prepare the lemon glaze by mixing the powdered sugar and lemon juice in a small bowl until smooth. This zesty glaze will add the final touch to your delicious blueberry creation.
Step 8: Drizzle and Serve
Once your Blueberry Coffee Cake has cooled, drizzle the lemon glaze generously over the top. Let it set for a couple of minutes, then slice your cake into wedges to serve. This delightful combination of moist cake, juicy blueberries, and zesty glaze is ready to be enjoyed with a cup of coffee or tea!

Blueberry Coffee Cake Recipe FAQs
What blueberries should I use for the best flavor?
Absolutely! Fresh blueberries are ideal for this cake as they provide a burst of juicy sweetness. If fresh isn’t available, you can use frozen blueberries, but don’t thaw them before adding them to your batter, as this can lead to a soggy cake.
How should I store my Blueberry Coffee Cake?
Very simple! Store your Blueberry Coffee Cake in an airtight container at room temperature for up to 2-3 days. If you need to keep it longer, consider refrigerating it for about 5 days but let it come to room temperature before serving to restore its moist texture.
Can I freeze Blueberry Coffee Cake, and if so, how?
Yes, you can freeze it! To do this, wrap individual slices in plastic wrap and then place them in a freezer-safe bag or container. This method preserves the cake’s flavor and can keep it fresh for up to 2-3 months. When you’re ready to enjoy a slice, just thaw it in the fridge overnight.
What should I do if my cake sinks in the middle?
If your Blueberry Coffee Cake sinks in the middle, it might be due to over-mixing the batter or not allowing it to bake long enough. Make sure to mix just until combined after adding the flour, and always check with a toothpick for doneness before removing it from the oven. A clean toothpick should indicate the cake is fully baked.
Are there any allergy considerations for this recipe?
Yes, if you’re preparing this Blueberry Coffee Cake for someone with dietary restrictions, there are options! You can replace the butter with vegan butter and use aquafaba instead of eggs for a vegan version. If nut allergies are a factor, make sure to avoid any nuts in the crumble topping.
Can I make substitutions for sugar in this Blueberry Coffee Cake?
While I recommend sticking with granulated sugar for the best results, you might want to experiment with alternatives like coconut sugar or a sugar substitute. Just be aware that this may change the texture and color slightly, and it’s often best to use recipes specifically designed for those ingredients.
