Ingredients
List of Ingredients
- 2 cups all-purpose flour
- 1 cup granulated sugar
- 1/2 cup unsalted butter, softened
- 1 cup sour cream
- 3 large eggs
- 2 teaspoons baking powder
- 1 teaspoon baking soda
- 1 teaspoon vanilla extract
- 2 cups fresh blueberries, rinsed and drained
- 1/2 teaspoon salt
- 1/2 cup rolled oats
- 1/4 cup packed brown sugar
- 1 teaspoon ground cinnamon
Ingredient Substitutions
You can switch all-purpose flour with whole wheat flour for more fiber. Greek yogurt makes a great substitute for sour cream. Use coconut oil instead of butter for a dairy-free option. If you need to, you can replace granulated sugar with a sugar substitute like stevia.
Recommended Brands and Quality Tips
I prefer Bob's Red Mill for flour. Their products are high quality. For sugar, Domino is a reliable choice. When it comes to butter, use a brand like Kerrygold for rich taste. Always choose fresh blueberries that are firm and plump. Check for mold before buying. Quality ingredients make a big difference in flavor.

Step-by-Step Instructions
Preheat and Prepare
Start by preheating your oven to 350°F (175°C). Grease a 9x13 inch baking pan with butter or non-stick spray. This step helps the cake come out easily after baking.
Mixing the Batter
In a large bowl, cream together 1/2 cup softened butter and 1 cup sugar using an electric mixer. Mix for about 3-4 minutes until light and fluffy. This adds air and makes the cake soft. Then, add 3 large eggs one at a time, mixing after each. Pour in 1 cup of sour cream and 1 teaspoon vanilla extract. Stir until smooth.
In another bowl, whisk together 2 cups all-purpose flour, 2 teaspoons baking powder, 1 teaspoon baking soda, and 1/2 teaspoon salt. Gradually add this to the wet mixture, stirring gently. Don’t overmix; this helps keep the cake light.
Adding Blueberries and Crumble Topping
Carefully fold in 2 cups of fresh blueberries. Use a spatula to avoid crushing them. This step ensures sweet bursts in every bite. In a new bowl, mix 1/2 cup rolled oats, 1/4 cup brown sugar, and 1 teaspoon ground cinnamon. Add 2 tablespoons of softened butter. Use your fingers or a fork to mix until crumbly.
Baking and Cooling Process
Pour half of the batter into the prepared pan and spread it evenly. Add half of the crumble topping over this layer. Then, spread the remaining batter on top and finish with the rest of the crumble.
Bake for 45-50 minutes. Use a toothpick to check if it's done; it should come out clean. The top should be golden brown. Once baked, let the cake cool in the pan for 15 minutes. Slice into 12 pieces and enjoy warm or at room temperature.
Tips & Tricks
How to Achieve a Fluffy Texture
To make your cake fluffy, start with room temperature butter. Cream it well with sugar until light and airy. This may take about 3-4 minutes. Adding eggs one at a time helps too. It allows air to mix in. When adding flour, mix gently. Overmixing can lead to a dense cake.
Common Mistakes to Avoid
Avoid using cold ingredients. Cold eggs and butter can hinder the mixing process. Also, don’t skip the creaming step. This step adds air, which is key for fluffiness. Be careful when folding in the blueberries. If you crush them, your cake may turn blue. Lastly, don’t forget to check the baking time. Every oven is different.
Best Practices for Blueberry Handling
When using fresh blueberries, rinse them gently. Drain them well to avoid excess moisture. You can toss them with a bit of flour before adding them to the batter. This helps prevent sinking. Make sure to fold them in last. This keeps them whole and juicy in the cake. Enjoy the flavor they bring!
Pro Tips
- Use Fresh Blueberries: For the best flavor and texture, always opt for fresh blueberries. If using frozen, ensure they are thawed and drained to avoid excess moisture in the batter.
- Room Temperature Ingredients: Make sure your eggs and butter are at room temperature. This helps the batter mix more evenly, contributing to a light and fluffy cake.
- Don't Overmix: When combining the dry ingredients with the wet, mix just until incorporated. Overmixing can lead to a dense cake instead of a light and airy texture.
- Check for Doneness: Ovens vary, so start checking your cake a few minutes before the minimum baking time. A toothpick should come out clean when the cake is done.
Variations
Gluten-Free Blueberry Crumble Coffee Cake
You can make a gluten-free version of this cake. Use gluten-free flour instead of all-purpose flour. This swap works well, and the cake stays moist. Add a bit of xanthan gum to help it rise. You won’t lose the flavor or texture. Your friends will love this option too!
Vegan Blueberry Crumble Coffee Cake
To make a vegan version, swap eggs for flax eggs. Mix one tablespoon of flaxseed meal with three tablespoons of water. Let it sit until it thickens. Use plant-based butter and dairy-free sour cream as well. The blueberries will keep the cake moist and tasty. You’ll enjoy this lighter twist!
Seasonal Fruit Substitutions
Feel free to change the blueberries with other fruits. Raspberries, strawberries, or peaches work great. Just make sure the fruits are ripe and fresh. You can also mix fruits for a fun flavor. This way, you can enjoy the cake all year long!
Storage Info
How to Store Leftovers
To keep your blueberry crumble coffee cake fresh, store it in an airtight container. Place it at room temperature if you plan to eat it within two days. For longer storage, move it to the fridge. This cake stays tasty for about five days in the fridge. Just make sure to cover it well to avoid drying out.
Freezing Instructions
If you want to save some for later, freezing is a great option. First, let the cake cool completely. Then, slice it into pieces. Wrap each slice in plastic wrap, followed by aluminum foil. This helps to prevent freezer burn. You can freeze it for up to three months. When you're ready to enjoy it, just thaw it overnight in the fridge.
Reheating Tips
To bring back that fresh-baked taste, reheat slices in the oven. Preheat your oven to 350°F (175°C). Place the slices on a baking sheet and heat for about 10-15 minutes. You can also use a microwave. Heat on a low setting for about 30 seconds to one minute. This warms the cake without drying it out. Enjoy your slice warm for the best flavor!
