Ingredients
List of Ingredients
– 2 cups all-purpose flour
– 1 cup granulated sugar

– 1 cup fresh blueberries (or frozen, thawed)
– 2 large eggs
– 1 teaspoon vanilla extract
– 1 teaspoon baking powder

Measurement Details
When you measure flour, scoop it into a cup and level it off. This helps avoid too much flour. For sugar, spoon it into your measuring cup and level it too. Use room temperature butter for easy mixing. Eggs should be medium or large size. The sour cream adds moisture, so don’t skip it. Lemon zest brightens the flavor and adds a nice twist.
Alternative Ingredient Suggestions
If you want a gluten-free option, you can use a gluten-free flour blend. You can swap sour cream with Greek yogurt for a similar texture. For a dairy-free option, use coconut oil instead of butter and a plant-based yogurt. You can also try different fruits like raspberries or strawberries for a fun twist.

Step-by-Step Instructions
Preheat the Oven
First, preheat your oven to 350°F (175°C). This step is key for even baking. Grease a 9×13 inch baking dish or line it with parchment paper. This helps with easy removal later.
Prepare the Crumb Topping
In a small bowl, mix together ½ cup of flour, ⅓ cup of brown sugar, ¼ cup of melted butter, and ½ teaspoon of cinnamon. Stir until it looks like coarse crumbs. Set this mixture aside. It adds a nice crunch to your cake.
Make the Cake Batter
In a large bowl, cream ½ cup of softened butter with 1 cup of granulated sugar. Mix well until it is light and fluffy. This should take about 3-4 minutes. Creaming helps to add air into the batter.
Add Eggs and Vanilla
Now, beat in 2 large eggs, one at a time. After that, add 1 teaspoon of vanilla extract and 1 teaspoon of lemon zest. Mix until everything is well combined. The lemon zest gives a fresh taste.
Mix Dry Ingredients
In another bowl, whisk together 2 cups of flour, 1 teaspoon of baking powder, ½ teaspoon of baking soda, and ½ teaspoon of salt. Mixing these dry ingredients first helps to ensure they are evenly distributed.
Combine Mixtures
Gradually add the dry mixture to the wet mixture, alternating with 1 cup of sour cream. Start and end with the dry mix. Stir until just combined. This keeps the batter from becoming too tough.
Fold in Blueberries
Now, gently fold in 1 cup of fresh or thawed blueberries. Be careful not to break them. This adds bursts of flavor in every bite.
Transfer to Baking Dish
Pour the batter into the prepared baking dish. Spread it evenly with a spatula. This helps the cake to bake evenly.
Add Crumb Topping
Sprinkle the crumb topping evenly over the batter. Make sure it covers the entire surface. This will create a nice, crunchy layer.
Bake and Cool
Place the coffee cake in your preheated oven. Bake for about 40-45 minutes. Use a toothpick to check if it’s done. It should come out clean. Let the cake cool in the pan for 15 minutes, then transfer it to a wire rack to cool completely. Enjoy your delicious treat!
Tips & Tricks
Baking Tips for Moisture
To keep your coffee cake moist, use sour cream. It adds creaminess and flavor. Remember to measure your flour correctly. Too much flour can make it dry. Scoop and level your flour, rather than packing it down. This way, you get just the right amount.
How to Avoid Sinking Blueberries
To prevent sinking blueberries, toss them in a bit of flour before adding them to the batter. This helps them stay suspended while baking. Also, fold them in gently. This keeps them whole and bright in your cake.
Ensuring Even Baking
To ensure your coffee cake bakes evenly, rotate the pan halfway through baking. This helps with hot spots in the oven. Use an oven thermometer to check your temperature accuracy. Each oven is different, and small changes can impact your bake. Let it cool in the pan before moving it. This step helps set the texture and makes slicing easier.
Pro Tips
- Fresh Blueberries are Best: Whenever possible, use fresh blueberries for the best flavor and texture. If using frozen, ensure they are thawed and drained before adding to the batter.
- Room Temperature Ingredients: Make sure your butter, eggs, and sour cream are at room temperature to ensure a smooth batter and even baking.
- Don’t Overmix: When combining wet and dry ingredients, mix just until combined. Overmixing can lead to a dense cake.
- Perfect for Make-Ahead: This coffee cake can be made a day ahead. Just store it covered at room temperature and reheat slices in the microwave for a few seconds before serving.
Variations
Substitutions for Gluten-Free Option
You can easily make this cake gluten-free. Use gluten-free all-purpose flour instead of regular flour. Check the blend to ensure it has xanthan gum. This helps mimic the texture of wheat flour.
Alternative Fruits for Flavor
While blueberries shine in this cake, you can switch them out. Try raspberries, chopped strawberries, or diced peaches. Each fruit brings a new taste. Just keep the same amount as the blueberries called for in the recipe.
Seasonal Variations: Adding Spices
You can add spices to match the seasons. In fall, try cinnamon or nutmeg for warmth. In spring, add a hint of cardamom for a fresh twist. These spices can elevate your coffee cake, making it special for any time of year.
