Step-by-Step Instructions
For the Lemon Cupcakes:
- Preheat and Prepare: Preheat your oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners or grease and flour the cups thoroughly.
- Combine Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. Set aside.
- Cream Butter and Sugar: In a large bowl, using an electric mixer (stand mixer or hand mixer), beat the softened unsalted butter and granulated sugar on medium-high speed until light and fluffy, about 3-4 minutes.
- Add Eggs and Flavor: Beat in the eggs one at a time, mixing well after each addition. Stir in the finely grated lemon zest and fresh lemon juice until incorporated.
- Combine Wet Ingredients: In a small bowl or liquid measuring cup, whisk together the buttermilk and vanilla extract.
- Alternate Adding Dry and Wet: Gradually add the dry ingredients to the butter mixture in three additions, alternating with the wet ingredients in two additions, beginning and ending with the dry ingredients. Mix on low speed until just combined after each addition. Be careful not to overmix. Scrape down the sides of the bowl as needed.
- Fill Muffin Cups: Divide the batter evenly among the prepared muffin cups, filling each about two-thirds full.
- Bake: Bake for 18-22 minutes, or until a wooden skewer or toothpick inserted into the center of a cupcake comes out clean.
- Cool: Let the cupcakes cool in the muffin tin for 5-10 minutes before transferring them to a wire rack to cool completely. Ensure they are completely cool before frosting.
For the Blueberry Buttercream:
- Cream Butter: In a large bowl, using an electric mixer, beat the softened unsalted butter until creamy and smooth.
- Add Powdered Sugar: Gradually add the sifted powdered sugar, about a cup at a time, mixing on low speed until just combined. Then, increase the speed to medium-high and beat until smooth and well incorporated.
- Incorporate Blueberry Puree: Add the pureed blueberries, milk or cream, vanilla extract, and a pinch of salt.
- Beat Until Fluffy: Beat on medium-high speed for 2-3 minutes until the buttercream is light, fluffy, and the color is a vibrant, appealing blue. If the frosting is too thick, add a little more milk, a teaspoon at a time. If it’s too thin, add a little more powdered sugar.
- Frost Cupcakes: Once the lemon cupcakes are completely cool, generously frost them with the blueberry buttercream using a piping bag or a spatula.

Storing and Reheating Tips
Storing Lemon Cupcakes with Blueberry Buttercream:
- Refrigeration for Buttercream: Because the buttercream contains dairy, it’s best to store frosted cupcakes in an airtight container in the refrigerator.
- Chilled Cupcakes: They will stay fresh in the refrigerator for up to 3-4 days.
- Bring to Room Temperature: Before serving chilled cupcakes, allow them to sit at room temperature for about 15-30 minutes. This will ensure the cake is tender and the buttercream is soft and spreadable.
- Unfrosted Cupcakes: If you have unfrosted cupcakes, they can be stored in an airtight container at room temperature for up to 2 days or frozen for up to 1 month.
Freezing:
- Freeze Unfrosted Cupcakes: For best results, freeze unfrosted cupcakes. Wrap them individually in plastic wrap, then place them in a freezer-safe airtight container or bag.
- Freezing Buttercream: You can also freeze leftover blueberry buttercream. Place it in an airtight container or a freezer bag, pressing out as much air as possible.
- Thawing: To thaw unfrosted cupcakes, remove them from the freezer and let them come to room temperature. To thaw buttercream, refrigerate it overnight, then let it soften at room temperature before re-whipping.
Reheating:
- These cupcakes are best enjoyed at room temperature and do not require reheating. However, if they have been refrigerated and you wish to quickly soften the buttercream, you can place them in a slightly warmed oven (around 200°F / 95°C) for just a couple of minutes, keeping a very close eye on them to prevent over-baking or melting the frosting.
Final Thoughts
These Lemon Cupcakes with Blueberry Buttercream are a beautiful symphony of vibrant flavors and cheerful colors, perfect for any occasion that calls for a sweet celebration. Encourage yourself to bake these at home; the joy of creating such delightful treats is as rewarding as their delicious taste!
