Blueberry Lavender Cake Recipe

I recently made this Blueberry Lavender Cake Recipe, and it instantly became a new favorite.

The aroma of lavender while it bakes is simply heavenly, and the flavor combination is so elegant and unique.

It’s the kind of simple, beautiful cake that brings a sense of calm and is perfect for any occasion.

This recipe is surprisingly straightforward, and the result is a moist, flavorful cake that I’m so excited to share with you. Every bite feels like a special treat.

Ingredients You’ll Need

Here are the ingredients that come together to create this delightful cake. Using fresh, high-quality ingredients will give you the best results.

For the Cake:

• 1 ½ cups unsalted butter, at room temperature – Using room temperature butter is crucial for a light and fluffy texture, as it creams with the sugar much more effectively.
• 2 cups granulated sugar – This provides the sweetness and contributes to the cake’s moist crumb.
• 3 large eggs, plus 3 egg yolks – The extra yolks add richness, moisture, and a tender texture to the cake.
• 1 teaspoon vanilla extract – A classic flavor enhancer that complements the other ingredients beautifully.
• 3 cups cake flour, plus 2 tablespoons for dusting blueberries – Cake flour has a lower protein content, which results in a finer, more delicate crumb.
• 1 ½ teaspoon baking powder – This is the primary leavening agent that helps the cake rise.
• ⅛ teaspoon baking soda – Works with the baking powder to ensure a perfect lift and tender texture.
• ½ teaspoon salt – Balances the sweetness and enhances all the other flavors in the cake.
• 1 cup 2% milk – Provides moisture and helps bind the ingredients together. Whole milk can also be used for a richer cake.
• 1 ¼ cup fresh blueberries – It’s best to use fresh blueberries as frozen ones can add too much moisture and bleed color into the batter.

For the Lavender Simple Syrup:

• ¼ cup water – The liquid base for creating the syrup.
• ¼ cup granulated sugar – Dissolves into the water to create the sweet syrup.
• 2 tablespoons dried lavender – Be sure to use culinary-grade lavender for the best flavor and to ensure it’s safe for consumption.

For the Blueberry Buttercream:

• 1 cup unsalted butter, at room temperature – Just like in the cake, room temperature butter is key for a smooth, creamy frosting.
• 2 ½ cups confectioners’ sugar – Also known as powdered sugar, it dissolves easily to create a silky-smooth buttercream.
• 2 tablespoons 2% milk – Helps to thin the buttercream to the perfect spreading consistency.
• 15 fresh blueberries – These are mashed into the frosting to give it a natural blueberry flavor and a beautiful, pale purple hue.

Note: The quantities provided will yield one 8-inch, two-layer cake, serving approximately 12-16 people.

Variations

This recipe is wonderful as is, but you can easily adapt it to suit your tastes or dietary needs.

• Dairy-Free Option: Substitute the unsalted butter with a high-quality vegan butter substitute and use a plant-based milk like almond, soy, or oat milk in both the cake and the buttercream.
• Gluten-Free Flour: You can swap the cake flour for a 1-to-1 gluten-free baking flour blend. Ensure your blend contains xanthan gum to help with the structure.
• Other Berries: While blueberries are classic, you could experiment with fresh raspberries or finely chopped strawberries for a different flavor profile.
• Lemon Zest: Add the zest of one lemon to the cake batter along with the wet ingredients for a bright, citrusy note that pairs beautifully with blueberry and lavender.
• Sugar-Free Alternative: For a lower-sugar version, you can use a granulated sugar substitute like erythritol or stevia in the cake and syrup, and a powdered sugar substitute in the buttercream. Keep in mind that this may alter the texture slightly.

Cooking Time

• Prep Time: 30 minutes
• Cook Time: 50-60 minutes
• Total Time: 1 hour 30 minutes (plus cooling time)

Equipment You Need

• Two 8-inch round baking pans – To bake the two layers of the cake evenly.
• Stand mixer or hand mixer – For creaming the butter and sugar and mixing the batter and frosting efficiently.
• Small saucepan – To prepare the lavender simple syrup on the stovetop.
• Offset spatula – This tool makes it much easier to spread the buttercream smoothly over the cake layers.
• Wire cooling rack – Essential for allowing the cakes to cool completely without getting soggy on the bottom.

Prepare the Oven and Pans

First, preheat your oven to 350°F (177°C). Grease and flour two 8-inch round baking pans. For extra insurance against sticking, place a round piece of parchment paper on the bottom of each pan.

Mix the Wet and Dry Ingredients

In the bowl of a stand mixer, beat the room temperature butter and granulated sugar for about 5 minutes until the mixture is light and fluffy. In a separate small bowl, whisk together the eggs, egg yolks, and vanilla extract. With the mixer on low, slowly pour this egg mixture into the butter and sugar until just combined. In a larger bowl, whisk together 3 cups of cake flour, baking powder, baking soda, and salt.

Combine to Make the Batter

Alternate adding the dry flour mixture and the milk to the wet ingredients, beginning and ending with the flour. Add about one-third of the flour mixture and mix, then half of the milk and mix. Repeat with another third of the flour, the rest of the milk, and finally the last of the flour, mixing until just incorporated after each addition.

Fold in the Blueberries

In a small bowl, toss the fresh blueberries with the remaining 2 tablespoons of cake flour. This light coating helps prevent them from sinking to the bottom of the cake during baking. Gently fold the flour-dusted blueberries into the batter with a spatula.

Bake the Cakes

Divide the batter evenly between your two prepared pans. Bake for 50-60 minutes, or until a wooden skewer inserted into the center comes out clean. Let the cakes cool in the pans for about 15 minutes before inverting them onto a wire rack to cool completely.

Make the Lavender Simple Syrup

While the cakes are baking, prepare the simple syrup. Combine the water and sugar in a small saucepan and bring it to a gentle simmer, stirring until the sugar dissolves completely. Remove from the heat, add the dried lavender, and gently press the flowers with the back of a spoon to release their flavor. Let the syrup steep for at least 30 minutes, then strain out the lavender pieces.

Prepare the Blueberry Buttercream

In a clean stand mixer bowl, beat the room temperature butter, confectioners’ sugar, and milk until smooth and creamy. Add the fresh blueberries and continue to mix on low. The blueberries will burst, adding flecks of color and a subtle fruity flavor to the frosting.

Assemble the Cake

Once the cake layers are completely cool, place one layer on your cake stand. Brush half of the lavender simple syrup over the top, allowing it to soak in. Spread a generous layer of the blueberry buttercream over the syrup-soaked cake. Place the second cake layer on top, brush it with the remaining syrup, and frost the top and sides of the entire cake with the remaining buttercream.

Additional Tips for Making This Recipe Better

Having made this cake a few times, I’ve picked up a few tricks that really elevate the final result.

• Don’t skip sifting: I always sift my dry ingredients (flour, baking powder, soda, and salt) together. This step seems small, but it guarantees there are no lumps and helps create a much lighter, more tender cake crumb.
• Muddle the lavender: Before adding the lavender to the warm syrup, I like to gently muddle it in the saucepan. This helps release more of its essential oils, resulting in a more fragrant and flavorful simple syrup that really shines through in the cake.
• Use a cake strip: For perfectly flat cake layers, I sometimes use cake strips soaked in water and wrapped around the outside of my pans. This helps the cakes bake more evenly from the edge to the center, preventing doming and reducing the need for trimming.
• Apply a crumb coat: For a cleaner final look, I apply a very thin layer of buttercream all over the cake first—this is called a crumb coat. I then chill the cake for about 20 minutes before applying the final, thicker layer of frosting. This traps any loose crumbs and makes the final frosting application much smoother.

How to Serve Blueberry Lavender Cake?

This cake’s simple elegance speaks for itself, but a few touches can make it even more special. Serve slices at room temperature to ensure the buttercream and cake are soft and flavorful.

For a beautiful presentation, garnish the top with a sprinkle of fresh blueberries and a few fresh lavender sprigs. You can also create a small wreath of blueberries in the center of the cake before serving.

A dollop of freshly whipped cream or a scoop of vanilla bean ice cream on the side is a wonderful complement to the flavors.

Make Ahead and Storage

Proper storage will keep your cake fresh and delicious for days.

Storing

Store the cake in an airtight container in the refrigerator for up to 5 days. For the best flavor and texture, allow slices to come to room temperature for about 20-30 minutes before serving.

Freezing

You can freeze the unfrosted cake layers by wrapping them tightly in plastic wrap and then aluminum foil for up to 3 months. To freeze the frosted cake, place it in the freezer uncovered for an hour until firm, then wrap it well.

Reheating

Thaw frozen cake layers or a frosted cake in the refrigerator overnight. There is no need to reheat the cake; it should be served at room temperature for the best experience.
