Ingredients
For the Lemon Cupcakes
- 1 1/2 cups all-purpose flour
- 2 teaspoons baking powder
- 1/4 teaspoon salt
- 1/4 cup milk, room temperature
- 1/4 cup sour cream, room temperature
- 1 cup granulated sugar
- 1 Tablespoon lemon zest (approximately 1 large lemon)
- 1/2 cup unsalted butter, room temperature
- 2 large eggs, room temperature
- 1/4 cup fresh lemon juice (approximately 1 1/2 large lemons)
- 1 teaspoon pure vanilla extract
For the Lavender Buttercream
- 1 cup unsalted butter, room temperature
- 3-4 cups powdered sugar
- 1-2 teaspoons ground dried lavender (culinary grade)
- 2-3 Tablespoons milk, room temperature
- 1 teaspoon pure vanilla extract
- Pink and violet food coloring (optional)
- Lavender buds for garnish (optional)
Instructions
- Mise en place: Measure and prepare all ingredients. Preheat your oven to 350°F (175°C). Line a cupcake tin with cupcake liners to prepare for baking.
- Prepare dry ingredients: In a medium bowl, whisk together the all-purpose flour, baking powder, and salt. Set aside for later use.
- Combine wet ingredients: In a separate measuring cup, mix the milk and sour cream together until well blended.
- Infuse the sugar with lemon zest: Place the granulated sugar and lemon zest in the bowl of a stand mixer. Rub them together between your fingers for about one minute to release the lemon oils, enhancing the flavor.
- Cream butter and sugar: Add the unsalted butter into the stand mixer bowl with the infused sugar. Using the paddle attachment, beat on medium speed until the mixture is light and fluffy, about 2 to 3 minutes. Stop once to scrape down the sides of the bowl to ensure even mixing.
- Add eggs and flavorings: Beat in the eggs one at a time until fully incorporated. Then add the fresh lemon juice and vanilla extract, mixing until combined. Scrape the bowl as needed to ensure everything is evenly mixed.
- Combine dry and wet mixtures: Gradually add the flour mixture and the milk-sour cream mixture in alternating batches to the batter, starting and ending with the flour mixture. Mix only until just combined to keep the cupcakes tender and light.
- Fill cupcake liners: Spoon the batter evenly into the 12 prepared cupcake liners, filling each about two-thirds full to allow for proper rising.
- Bake and cool: Bake the cupcakes in the preheated oven for 18 to 20 minutes, or until a toothpick inserted into the center comes out clean. Remove from the oven and let cool completely in the cupcake pan set on a wire rack.
- Prepare lavender buttercream: While cupcakes cool, grind dried lavender buds by placing them in a zip-top bag and crushing with a rolling pin. In a clean mixing bowl with the paddle attachment, beat the butter on medium speed until creamy (about 1 minute).
- Add lavender and vanilla: Stir in 1 teaspoon of the ground lavender along with the vanilla extract. Continue mixing until fully incorporated and creamy, about another minute.
- Incorporate powdered sugar and milk: Add 3 1/2 cups (about 400g) powdered sugar and 2 Tablespoons milk to the butter mixture. Beat on low speed for 30 seconds, then increase speed to medium-high and beat for 2 minutes. Scrape down the sides and bottom of the bowl thoroughly.
- Adjust frosting consistency and flavor: If the frosting is too thin, add powdered sugar up to 1/2 cup more, 1/4 cup at a time. If too thick, add more milk in 1/2 Tablespoon increments. Add more lavender (up to 1 additional teaspoon) if needed and a pinch of salt (1/8 teaspoon) if it tastes overly sweet. Beat and taste frequently to finalize flavor and texture.
- Color the frosting: Optional: Add a small amount of pink and violet food coloring (using a toothpick to control quantity) to achieve a soft pastel lavender shade. Mix until evenly colored.
- Frost the cupcakes: Fill a piping bag with the prepared buttercream. Starting in the center of each cooled cupcake, pipe a swirl upwards using medium pressure. Garnish with whole lavender buds if desired for an elegant finish.
Notes
- Use room temperature ingredients for optimal batter consistency and cupcake texture.
- Be careful not to overmix the batter once dry ingredients are added to avoid dense cupcakes.
- Ground lavender is culinary-grade and should be used sparingly for a pleasant floral note without bitterness.
- Adjust frosting thickness by varying powdered sugar and milk gradually for best results.
- These cupcakes can be stored in an airtight container at room temperature for up to 2 days or refrigerated for up to 5 days.
- Allow refrigerated cupcakes to return to room temperature before serving for best taste and texture.
