Ingredients
List of Ingredients
- 2 cups all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup unsalted butter, softened
- 1 cup granulated sugar
- 2 large eggs
- 1 tablespoon freshly grated lemon zest
- 1/4 cup freshly squeezed lemon juice
- 1 cup sour cream
- 1 1/2 cups fresh blueberries (or frozen)
- Powdered sugar (optional for dusting)
Substitutions for Ingredients
If you don’t have sour cream, you can use plain yogurt. This will keep the cake moist. If you need a dairy-free option, try coconut yogurt. For gluten-free needs, use a gluten-free flour blend. You can also swap blueberries for other berries, like raspberries or blackberries.
Importance of Fresh Ingredients
Using fresh ingredients makes a big difference. Fresh blueberries burst with flavor and moisture. Fresh lemons add bright taste and aroma. When you use these, your cake will taste amazing. If you use older ingredients, the cake may not rise well or have the same flavor. Always check the quality of your ingredients before baking. Freshness ensures your lemon blueberry coffee cake is a hit every time!

Step-by-Step Instructions
Prepping the Oven and Cake Pan
Start by preheating your oven to 350°F (175°C). This ensures even baking. Take a 9-inch round cake pan and grease it with butter. Dust the pan with flour or use parchment paper at the bottom. This helps the cake come out easily after baking.
Mixing Dry Ingredients
Grab a medium bowl. Combine 2 cups of all-purpose flour, 1 teaspoon of baking powder, 1/2 teaspoon of baking soda, and 1/4 teaspoon of salt. Whisk these dry ingredients until they are mixed well. Set this bowl aside for later.
Creaming Butter and Sugar
In a large bowl, take 1/2 cup of softened unsalted butter and 1 cup of granulated sugar. Use an electric mixer to beat them together at medium speed. Mix until the mixture becomes light and fluffy. This takes about 3 to 4 minutes.
Combining Wet and Dry Ingredients
Add the eggs, one at a time, to the creamed butter and sugar mixture. Make sure each egg blends in fully before adding the next one. Then add 1 tablespoon of lemon zest and 1/4 cup of lemon juice. Mix well. Now, take the dry mixture and gradually add it to the wet mix. Alternate with 1 cup of sour cream, starting and ending with the dry mix. Mix on low speed until just combined.
Incorporating Blueberries
Now, it’s time to add 1 1/2 cups of fresh blueberries. Use a spatula to fold them gently into the batter. Be careful not to crush the berries, as you want to keep them whole.
Baking and Cooling the Cake
Pour the batter into your prepared cake pan. Smooth the top with a spatula. Place it in the oven and bake for 40 to 45 minutes. To check for doneness, insert a toothpick into the center. It should come out clean or with a few moist crumbs. Once baked, let the cake cool in the pan for about 10 minutes. After that, transfer it to a wire rack to cool completely. This helps keep it from getting soggy.
Tips & Tricks
How to Get a Light and Fluffy Cake
To get a light and fluffy cake, cream the butter and sugar well. Use an electric mixer on medium speed for about 3-4 minutes. This process adds air to the mix. The more air, the fluffier the cake! Make sure your butter is softened, as cold butter won’t blend well.
Avoiding Overmixing
Mix just until combined when adding the dry ingredients. Overmixing can make your cake tough. You want a tender crumb, not a dense brick. After adding each egg, mix just enough to blend it. This keeps the cake light and airy.
Best Practices for Folding Blueberries
When adding blueberries, use a spatula to fold them in gently. This prevents them from breaking apart. Start from the bottom and lift the batter over the berries. Do this carefully, so you keep the berries whole. Whole blueberries add great texture and flavor to your cake!
Pro Tips
- Use Room Temperature Ingredients: Ensuring your butter, eggs, and sour cream are at room temperature helps create a smoother batter and contributes to a light, fluffy texture in your coffee cake.
- Fresh vs. Frozen Blueberries: While fresh blueberries are ideal, if using frozen, do not thaw them. Adding them directly to the batter helps prevent the cake from becoming too wet and ensures a burst of flavor in every bite.
- Mixing Technique: Be gentle when folding in the blueberries. Overmixing can break them apart and result in a colored batter rather than the beautiful swirls of blueberry throughout the cake.
- Storage Tips: To keep your cake fresh, store it in an airtight container at room temperature for up to 3 days. For longer storage, you can freeze individual slices wrapped in plastic wrap and foil for up to 2 months.
Variations
Lemon Blueberry Muffins Option
You can easily turn this coffee cake into muffins. Just use the same batter. Fill muffin cups about two-thirds full. Bake for 18 to 20 minutes. Check with a toothpick to see if they are done. This way, you can enjoy lemon blueberry muffins any time.
Adding Nuts or Toppings
Want some crunch? Add nuts like walnuts or pecans. Mix about half a cup into the batter. You can also sprinkle some on top before baking. For a sweet touch, try streusel topping made from flour, sugar, and butter. It adds texture and flavor.
Transforming into a Layered Cake
To make a layered cake, double the recipe. Bake two round cakes and let them cool. Place one on a plate, spread lemon frosting or whipped cream on top, and add berries. Then, add the second cake on top. This makes a stunning dessert for special occasions.
Storage Info
How to Store Leftovers
To keep your lemon blueberry coffee cake fresh, wrap it tightly in plastic wrap. You can also place it in an airtight container. Store it at room temperature for up to three days. If you want to keep it longer, refrigeration is a good option. However, it may dry out a bit in the fridge.
Freezing the Coffee Cake
Freezing is a great way to save your coffee cake. First, let it cool completely. Then, wrap individual slices in plastic wrap. Place the wrapped slices in a freezer-safe bag or container. This way, you can enjoy a slice whenever you want. The cake can stay fresh in the freezer for up to three months.
Reheating Tips for Best Freshness
When you're ready to enjoy your cake, reheating it can bring back its fresh flavor. For best results, heat a slice in the microwave for about 10-15 seconds. You can also warm it in an oven set to 350°F (175°C) for about 10 minutes. This helps restore its moist texture and bright flavor.
FAQs
Can I use frozen blueberries?
Yes, you can use frozen blueberries in this coffee cake. They work great when fresh ones are not in season. Just fold them in without thawing. This helps keep the batter from turning blue.
How do I know when the cake is done baking?
To check if the cake is done, insert a toothpick into the center. If it comes out clean or with a few moist crumbs, the cake is ready. I usually start checking at 40 minutes.
What can I substitute for sour cream?
You can use plain yogurt as a substitute for sour cream. It gives a similar texture and taste. Buttermilk also works well, adding a nice tang to the cake.
How long does the coffee cake last?
The coffee cake lasts about 3 to 4 days when stored in an airtight container. If you want it to last longer, you can freeze it. Just wrap slices tightly in plastic wrap.
