Lemon Blueberry Cake Ingredients
For the Cake
• Vanilla Cake Mix – This forms the base structure; feel free to experiment with other flavors if desired.
• Lemon Juice and Zest – Infuses the cake with a refreshing tartness; can be swapped for lime if you’re in the mood for something different.
• Fresh Blueberries – These bursts of sweetness elevate the cake; frozen berries can be used if fresh aren’t available—just remember to thaw and drain them.
• All-Purpose Flour – Helps to coat the blueberries and keep them from sinking; no substitutes recommended for this purpose.
For the Frosting
• Butter (2 sticks) – Adds rich flavor to your frosting; margarine can be used in a pinch but for the best taste, stick with butter.
• Powdered Sugar – This sweetens and gives the frosting its smooth texture; if you’re in a bind, granulated sugar can be turned into powdered sugar using a blender.
• Heavy Cream – Provides a silky texture that makes the frosting irresistible; half-and-half works if you need a substitute.
• Pure Vanilla Extract – Enhances the overall flavor; avoid imitation vanilla for the best experience!
• Kosher Salt – Balances the sweetness and elevates the flavors; any salt can be used, but keep an eye on the quantity.
For Decoration
• Thin Lemon Slices – These slices not only add a pop of color but also a hint of citrus flavor; they’re optional but highly recommended for visual appeal.
This Lemon Blueberry Cake is not just a treat; it’s a delightful experience, perfect for any sunny gathering or picnic. Enjoy!
How to Make Lemon Blueberry Cake
Preheat the Oven: Start by preheating your oven to 350°F (175°C). Grease three 9-inch cake pans and line the bottoms with parchment paper for easy release later.
Mix the Batter: Prepare the vanilla cake mix according to the package instructions, but add the zest and juice of one lemon to the mix. This will give your cake a refreshing zing!
Coat the Blueberries: In a small bowl, toss the fresh blueberries with a bit of all-purpose flour. This simple trick helps keep the berries from sinking during baking.
Combine Ingredients: Gently fold the coated blueberries into the lemony batter, being careful not to overmix. You want those beautiful berry pockets throughout your cake.
Bake the Cakes: Divide the batter evenly among the prepared pans. Bake in the preheated oven for 18-20 minutes or until a toothpick inserted into the center comes out clean. They should be golden and spring back when touched.
Cool Completely: Once baked, let the cakes cool in the pans for 10 minutes, then carefully invert them onto wire racks to cool completely. This is crucial for a smooth frosting later.
Prepare the Frosting: In a mixing bowl, beat together 2 sticks of softened butter and powdered sugar until light and fluffy. Then, mix in the lemon juice, zest, heavy cream, vanilla extract, and a pinch of salt until the frosting is smooth and spreadable.
Assemble the Cake: Place one cake layer on a serving plate, spread a generous layer of frosting on top, and repeat with the remaining layers. Smooth frosting over the sides and top of the cake for a beautiful finish.
Garnish: Decorate with fresh blueberries, thin lemon slices, and additional lemon zest for a visually stunning presentation.
Optional: Add a sprig of mint on top for an extra pop of color and freshness.

Expert Tips for Lemon Blueberry Cake
- Cool Before Frosting: Allow your cake layers to cool completely to prevent the frosting from melting and sliding off; patience pays off here!
- Coat Blueberries Well: Toss blueberries in flour thoroughly to ensure they stay suspended in the cake batter, avoiding that sinking issue common in lemon blueberry cake.
- Use a Rotating Stand: For even frosting, a rotating cake stand helps you evenly coat the sides and top, giving your dessert a professional touch.
- Adjust Frosting Texture: If your buttercream is too soft, add more powdered sugar; for a smoother consistency, incorporate a bit more heavy cream gradually.
- Layer with Lemon Curd: For a tangy surprise, consider adding a layer of lemon curd between the cake layers for extra flavor and moisture.

Lemon Blueberry Cake Recipe FAQs
What type of blueberries should I use in the Lemon Blueberry Cake?
