Mini Lavender Blueberry Cakes are my go-to treat for occasions that call for a bit of whimsy or when I want to impress guests with a delicate, floral dessert. Each cake features layers of fluffy vanilla sponge, a jammy blueberry center, and a dreamy lavender glaze, all topped with garden-inspired garnishes. These pretty cakes taste as enchanting as they look.
My first time making these was for a spring tea party with close friends. By the end of the afternoon, the little cakes were the star of the table and everyone asked for the recipe.
Ingredients
- All-purpose flour: gives the cakes a light tender crumb. Look for unbleached flour for the best texture
- Baking powder: ensures the sponge rises beautifully
- Salt: balances all the sweet and floral notes
- Unsalted butter: creates a rich buttery base. Choose high-quality butter for the best taste
- Sugar: sweetens everything just enough for a refined dessert
- Large eggs: give structure and moistness
- Vanilla extract: adds warmth and depth. Go for pure extract for real flavor
- Milk: keeps the cake tender. Whole milk works best
- Fresh or frozen blueberries: bring vibrant color and tartness
- Lemon juice: brightens the blueberry filling
- Cornstarch: thickens the filling so it holds in the layers
- Powdered sugar: melts into a smooth glaze
- Culinary lavender: gives the glaze its unique aroma. Only use food-grade dried lavender
- Purple gel food coloring: offers a pastel finish without watering down the glaze
- Fresh blueberries: decorate with extra fruitiness
- Mint leaves: add a pop of color and freshness
- Dried lavender buds: finish the look with style
- Violet sprinkles: offer sparkle and whimsy

- Make the Blueberry Filling:
