Dry Ingredients
- 2 3/4 cups all-purpose flour
- 2 teaspoons baking powder
- 1 teaspoon baking soda
- 1 teaspoon salt
Wet Ingredients for Cake
- 3 large eggs
- 1 cup granulated sugar
- 1 cup light brown sugar, loosely packed
- 1 cup unsalted butter, melted and cooled
- 1/3 cup canola or vegetable oil
- 2 tablespoons vanilla extract
- 1 cup sour cream
- 3/4 cup whole milk
Buttercream Frosting
- 1 1/2 cups unsalted butter, softened to room temperature
- 5 cups powdered sugar
- 2 teaspoons vanilla extract
- 1 tablespoon whole milk
- Pinch of salt
- Pink food coloring
- Yellow food coloring
- Purple food coloring
Lavender Syrup
- 3/4 cup water
- 3/4 cup sugar
- 1/4 cup dried culinary lavender
Dark Chocolate Ganache
- 1 (3.2 ounce) bar dark Chocolove dark chocolate, chopped
- 4 tablespoons heavy cream
Optional Garnish
- Make the lavender syrup: In a medium saucepan, combine water, sugar, and dried culinary lavender. Bring to a boil and stir for 30 seconds or until sugar dissolves. Remove from heat and let the syrup cool completely. Once cooled, strain through a fine mesh sieve into a bowl, discarding the lavender buds.
- Prepare cake pans and preheat oven: Preheat the oven to 350°F. Grease and flour three 8-inch round cake pans, then line the bottoms with parchment paper for easy removal.
- Mix dry ingredients: In a medium bowl, whisk together all-purpose flour, baking powder, baking soda, and salt until evenly combined. Set aside.
- Combine wet ingredients: In a large mixing bowl, whisk the eggs with granulated sugar and brown sugar until smooth. Add melted butter, vegetable oil, vanilla extract, and sour cream, whisking until fully incorporated. Stir in the whole milk until combined.
- Combine wet and dry ingredients: Gradually fold the dry ingredient mixture into the wet mixture using a rubber spatula, mixing until just combined to avoid overmixing.
- Bake the cake layers: Evenly divide the batter among the prepared pans and smooth the tops. Bake for 22-25 minutes or until a toothpick inserted in the centers comes out clean. Let cakes cool in pans for 10 minutes, then transfer to a wire rack to cool completely.
- Make the buttercream frosting: Using a stand mixer fitted with a paddle attachment, whip softened butter on medium-high for 2-3 minutes until light and fluffy. Reduce speed to low and gradually add powdered sugar. Add vanilla extract and milk, then whip again on medium-high for 2-3 minutes. Add a pinch of salt and whip for an additional 2-3 minutes until super fluffy. Divide the buttercream into three bowls and tint each separately with pink, yellow, and purple food coloring, mixing until fully combined.
- Assemble the cake: Place one cake layer on a plate or cooling rack. Spoon several spoonfuls of lavender syrup over the layer and allow it to soak in for a minute or two. Spread one color of buttercream evenly over the top. Repeat this process with the second layer—syrup soak, then spread with a different colored frosting. Add the third layer and repeat the syrup soak and frosting step. Use remaining frosting to create a semi-naked effect on the cake sides by applying the three colors randomly with an offset spatula or bench scraper, then smooth the sides evenly.
- Prepare the dark chocolate ganache: Place chopped dark chocolate in a medium bowl. Heat heavy cream in a small saucepan over medium heat until it simmers (do not boil). Pour the hot cream over the chocolate and let it sit for 2-3 minutes to soften. Stir gently until the ganache is smooth and pourable.
- Finish the cake: Let the ganache cool briefly, then pour it evenly over the top of the assembled cake, allowing it to drip down the sides decoratively. Garnish with edible flowers if desired. Serve immediately and enjoy!
Notes
- Use room temperature ingredients for smooth batter and frosting.
- Be careful not to overmix the batter to keep cakes tender.
- Adjust food coloring drops gradually to achieve desired frosting shades.
- The lavender syrup can be stored in the refrigerator for up to 1 week.
- Ganache sets as it cools; pour carefully for decorative drips.
- Allow cake layers to cool completely before assembling to prevent melting the frosting.
- For best results, use high-quality unsalted butter and dark chocolate.
