Lemon-Blueberry Cake Ingredients

For the Cake
• Vanilla Cake Mix – This is the base of your cake, providing sweetness and moisture; substitute with gluten-free cake mix if needed.
• Lemons (Juice and Zest) – Adds that irresistible acidity and fresh flavor, but feel free to use limes as a substitute.
• Fresh Blueberries – These little gems burst with natural sweetness; frozen blueberries can work too, just reduce the baking time.
• All-Purpose Flour – Coats the blueberries to prevent them from sinking; omit if you’re using a gluten-free flour blend.

For the Frosting
• Butter (Softened) – Essential for achieving a rich and creamy frosting; margarine can be used for a dairy-free option.
• Powdered Sugar – Sweetens and thickens your frosting; coconut sugar is a nice, less refined alternative.
• Heavy Cream – Provides smoothness and texture to your frosting; milk or a non-dairy alternative will work for a lighter version.
• Pure Vanilla Extract – Enhances the overall flavor of the frosting; almond extract can add an interesting twist.
• Kosher Salt – Balances the sweetness; it’s optional, but I recommend it for added depth.

This Lemon-Blueberry Cake is sure to become a summer favorite in your kitchen!

Step‑by‑Step Instructions for Lemon-Blueberry Cake

Step 1: Preparation
Begin by preheating your oven to 350ºF (175ºC). While the oven warms, grease three 9-inch round cake pans thoroughly and line the bottoms with parchment paper. This important step prevents the layers of your Lemon-Blueberry Cake from sticking, guaranteeing a smooth release after baking.

Step 2: Mix Batter
In a large mixing bowl, prepare the vanilla cake mix according to the package instructions, incorporating the zest and juice of your lemons for that zesty kick. Mix until combined and smooth, ensuring that it’s free of lumps. The vibrant batter will hint at the delightful flavor awaiting you when baked.

Step 3: Blueberry Prep
In a separate bowl, take your fresh blueberries and toss them with a small amount of all-purpose flour. This coating is crucial, as it will help prevent the blueberries from sinking in the batter while baking. Set this mixture aside to ensure the blueberries maintain their position for an even distribution throughout the cake.

Step 4: Combine Ingredients
Gently fold the coated blueberries into your prepared cake batter. Use a rubber spatula and make sure not to overmix, as you want to maintain the light and airy texture of the batter. The vibrant blue berries will create a beautiful marbled effect once baked, making every slice a feast for the eyes.

Step 5: Bake
Divide the lemon-blueberry cake batter evenly among the three prepared pans. Place them in the preheated oven and bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean. Watch for a golden hue on the edges, revealing that your cakes are perfectly baked.

Step 6: Cool Down
After baking, remove the cake layers from the oven and let them cool in the pans for about 10 minutes. Carefully transfer the cakes to a wire rack to cool completely. This step is crucial to avoid melting your frosting when you assemble your Lemon-Blueberry Cake later on.

Step 7: Make Frosting
While the cakes cool, prepare the frosting by beating the softened butter in a mixing bowl until creamy. Gradually add the powdered sugar, followed by lemon juice, zest, heavy cream, vanilla extract, and a pinch of salt. Continue blending until the mixture is smooth and fluffy, creating a luscious topping for your cake.

Step 8: Assemble Cake
Once the cake layers are completely cool, place one layer on a cake stand or plate. Generously frost the top with your creamy lemon frosting, then carefully add the second layer, repeating the process. Finally, frost the top and sides of the entire cake and decorate with fresh blueberries and lemon slices for a stunning presentation.

How to Store and Freeze Lemon-Blueberry Cake

Room Temperature: Store the cake for up to 3 days at room temperature, wrapped tightly in plastic wrap to maintain freshness and moisture.

Fridge: If you prefer, you can refrigerate the cake for up to a week; just ensure it’s covered properly to prevent it from drying out.

Freezer: For longer storage, freeze the cake layers for up to 3 months. Wrap each layer individually in plastic wrap, then place in a freezer bag to prevent freezer burn.

Reheating: When ready to enjoy, thaw the layers in the fridge overnight, then frost and serve your lemon-blueberry cake chilled or at room temperature.

Make Ahead Options

These delicious Lemon-Blueberry Cakes are perfect for busy home cooks looking to streamline their meal planning! You can bake the cake layers up to 3 days in advance; simply let them cool completely, then wrap each layer tightly in plastic wrap and refrigerate to keep them fresh. The buttercream frosting can also be made ahead, lasting up to 2 weeks in the fridge. Just remember to re-whip it before frosting the cake to restore its creamy texture. When you’re ready to serve, assemble the layers and frost them with the prepared buttercream, and your Lemon-Blueberry Cake will taste just as delightful as if made fresh that day!

Lemon-Blueberry Cake Recipe FAQs

How do I choose ripe blueberries for my Lemon-Blueberry Cake?
Absolutely! When selecting blueberries, look for plump, firm berries that are deep blue in color with a slight matte finish. Avoid any with dark spots or signs of moisture, as these can indicate overripeness. Fresh blueberries are best, but if you can’t find them, frozen blueberries can be a suitable alternative—just remember to reduce the baking time slightly to avoid overcooking.

What’s the best way to store leftover Lemon-Blueberry Cake?
Very! If you have leftovers, wrap your cake tightly in plastic wrap and store it at room temperature for up to 3 days. For longer preservation, you can refrigerate it for up to a week, but be sure to keep it covered to prevent it from drying out. When serving cake from the fridge, let it sit at room temperature for about 30 minutes to restore its fluffy texture.

Can I freeze my Lemon-Blueberry Cake?
Absolutely! To freeze the cake layers, wrap each layer individually in plastic wrap and place them in an airtight freezer bag. This helps prevent freezer burn and keeps them fresh. The cake can be stored in the freezer for up to 3 months. When you’re ready to enjoy it, thaw the layers in the fridge overnight before frosting!

What if my cake layers are sticking to the pans?
No worries! To prevent sticking, ensure that you grease and line your cake pans with parchment paper. If you’ve already baked them and they’re stuck, run a knife around the edges to loosen them. Additionally, let the cakes cool in the pans for about 10 minutes before transferring them to a wire rack—a little patience goes a long way!

Can dietary restrictions affect this Lemon-Blueberry Cake recipe?
Very much so! You can easily customize this cake for various dietary needs. For a gluten-free version, simply use a gluten-free cake mix and flour. If someone has dairy sensitivities, substitute butter with margarine or use a non-dairy butter alternative for the frosting. Always check the labels of your ingredients to ensure they fit your dietary restrictions.

How far in advance can I make the Lemon-Blueberry Cake?
Absolutely! You can make the cake layers up to a week in advance. Store them tightly wrapped at room temperature. For the buttercream frosting, feel free to prepare it up to two weeks ahead; just refrigerate it and give it a quick re-whip before frosting the cake. This planning will save you time and stress ahead of summer celebrations!
