This is the best lavender cake recipe ever! If you are looking for a homemade lavender cake with an incredible lavender flavor, then this cake recipe is for you.
Preheat the oven to 350°F. Grease and line a 9×9-inch pan (or two 8-inch round pans).
In a small bowl, combine 1 1/4 cups whole milk and 2 teaspoons dried lavender. Let sit for 15 minutes, then strain and discard the lavender.
In a bowl, sift together 2 1/4 cups cake flour, 1 tablespoon baking powder, and 1 teaspoon salt. Set aside.
In a mixer, beat 3/4 cup unsalted butter and 2 cups granulated sugar on medium speed until light and fluffy.
In a measuring cup, whisk together the strained lavender milk, 4 egg whites, 1 teaspoon vanilla extract, and 1 teaspoon lavender extract.
With the mixer on low speed, alternate adding the dry ingredients and wet ingredients until just combined. Scrape down the bowl as needed.
Pour batter into the prepared pan and bake for 25–30 minutes, until a toothpick inserted in the center comes out clean.
Once the cake has baked and cooled, carefully turn it upside down. Using a wooden toothpick, poke about 12 small holes evenly over the cake.
Using a pastry brush, brush about 1/2 of the lavender syrup (recipe below) evenly over the cake, allowing it to soak in.
Let the cake rest for a few minutes so the syrup fully absorbs before frosting.
