Tips and Tricks
- Use room temperature ingredients. Let the eggs, butter, and dairy warm on the counter before starting this easy lemon blueberry cake recipe.
This helps the batter come together smoothly and prevents lumps.
The exception is the heavy cream — that should be cold when whipped!
- Coat the berries first! Tossing the blueberries in a little bit of flour helps them to stay dispersed throughout the batter and not sink to the bottom of your lemon blueberry cake.
If using frozen berries, it also prevents color bleeding!
- Don’t have buttermilk? You can make a buttermilk substitute!
Add 1 tablespoon of vinegar or lemon juice to a measuring cup, then fill with regular milk until it reaches 1 ¼ cup total.
Let it sit for about 5 minutes, then give it a stir and use as directed.
- Whipped cream substitute: Instead of making your own, simply fold 2 cups of thawed Cool Whip into the cream cheese mixture.
How to Convert Sheet Cake into a Layer Cake
You can easily convert this lemon blueberry cake into a stunning layered dessert!
Divide the batter between two 9-inch round pans and bake for 20 to 25 minutes.
Transfer each layer to a wire rack, then poke holes in both cakes and drizzle with citrus glaze.
Once cooled, spread the cream cheese frosting between the layers and sprinkle in some blueberries.
Then, frost the outside of the blueberry lemon cake and top with additional fresh berries.
Blueberry Lemon Cake Recipe FAQ
Absolutely! Prepare a yellow or lemon box mix according to the package directions, but add 1 teaspoon of lemon extract and 1 tablespoon of zest.
Before baking, toss 2 cups frozen or fresh blueberries in 1 tablespoon of flour and fold them into the batter.
Unwrap the blocks completely and place them on a heat-safe plate. Microwave for 10 to 15 seconds until you can easily press your finger into the center.
There are usually two culprits for dry, dense cake: not measuring properly and overmixing.
Use the spoon and level method to measure out your flour and mix the batter just until combined. When it’s time to add the blueberries, gently and slowly fold them in.
