Directions for Cupcakes

Preheat your oven to 350°F (175°C). Line a cupcake pan with cupcake liners.
In a bowl, mix together the flour and baking powder. Set aside.
In a large bowl, cream the butter and sugar until light and fluffy.
Add in the eggs one at a time, mixing well after each addition.
Stir in the milk, lemon juice, lemon zest, and vanilla extract.
Gradually add the flour mixture to the wet ingredients, stirring until combined.
Gently fold in the fresh blueberries.
Fill each cupcake liner about two-thirds full with the batter.
Bake for 18-20 minutes or until a toothpick comes out clean.
Allow the cupcakes to cool completely before frosting.

Directions for Buttercream

In a bowl, beat the stick of unsalted butter until creamy.
Gradually add the powdered sugar, mixing until well combined.
Add the vanilla extract and a splash of milk if needed. Mix until the buttercream is smooth and fluffy.
Gently fold in the remaining blueberries for a touch of flavor and color.

How to Serve Lemon Cupcakes with Blueberry Buttercream

Once your cupcakes are cool, generously frost each one with the blueberry buttercream. For an extra touch, top each cupcake with a few fresh blueberries. These cupcakes are perfect for serving at parties or as a special treat after dinner.

How to Store Lemon Cupcakes with Blueberry Buttercream

Store leftover cupcakes in an airtight container at room temperature for up to three days. If you prefer to keep them longer, you can store them in the refrigerator for up to a week. Just be sure to bring them to room temperature before serving for the best taste.

Tips to Make Lemon Cupcakes with Blueberry Buttercream

Use fresh blueberries for the best flavor; frozen blueberries can be used but may alter the texture.
Make sure your butter is at room temperature for easier mixing and a creamier buttercream.
Don’t overmix the cupcake batter; mix just until combined to keep them light and fluffy.

Variation

You can switch the blueberries for different fruits, such as raspberries or strawberries, to create your preferred flavor. You can also add poppy seeds for an added texture.
