How to Make Lavender Cake – Step by Step

Step 1: Prepare Your Pans
Preheat oven to 350°F (177°C).

Grease and line two 8-inch cake pans with parchment paper.

Step 2: Mix the Dry Ingredients
In a bowl, whisk together flour, baking powder, salt, and crushed lavender. Set aside.

Step 3: Cream Butter and Sugar
Beat softened butter and granulated sugar together until light and fluffy.

Add whole eggs one at a time, followed by egg yolks and vanilla extract.

Step 4: Combine Wet and Dry
Alternate adding dry ingredients and buttermilk into the creamed mixture, starting and ending with dry.

Mix on low until just combined.

Step 5: Bake the Cake Layers
Divide batter evenly between pans. Bake 25–30 minutes, or until a toothpick comes out clean.

Cool in pans for 10 minutes, then transfer to wire rack.

Step 6: Make the Lavender Syrup
In a small saucepan, combine sugar, water, and lavender.

Simmer until sugar dissolves, steep 15–20 minutes, strain, and let cool completely.

Step 7: Make the Buttercream
Beat softened butter until creamy.

Gradually add powdered sugar, then lavender syrup and vanilla. Beat until fluffy.

Step 8: Assemble the Cake
Once cake layers are fully cool, level if needed.

Place one layer on your serving plate.

Brush generously with syrup, then spread a layer of buttercream.

Top with second layer (upside down), brush with syrup.

Step 9: Frost and Decorate
Apply a thin crumb coat and chill for 15–20 minutes.

Frost the entire cake with remaining buttercream and decorate as desired.
