I’m so excited to share these Lemon Blueberry Cupcakes with Blueberry Buttercream with you today for the Seasonal Simplicity Series hosted by my friend Krista of The Happy Housie!

Lemon Blueberry Cupcakes with Blueberry Buttercream

The Lemon Blueberry Cupcakes come from a modified version of Martha Stewart’s Lemon Meringue Cupcake recipe. It is my go-to lemon cake recipe, with some changes I have made over time.


The blueberries are a perfect tangy addition to these creamy cupcakes! The Blueberry Buttercream is based on my own personal buttercream recipe. The blueberry puree takes the place of the heavy cream I usually add to my frosting (and I’ve also made it with raspberry, strawberry, and blackberry puree- yum!). One thing I should add, I find these cupcakes to be very sweet. So if that isn’t so much your thing, you can consider cutting back on the sugar in the recipe.

I hope you enjoy these fun summer treats. I know my family did!

Lemon Blueberry Cupcakes

Servings 24 Cupcakes


Lemon Blueberry Cupcake Ingredients:

  • 3 cups self-rising flour I love White Lily Self-Rising Flour or 3 cups all-purpose flour + 1 tbsp baking powder
  • 1/2 tsp salt
  • 1 cup 2 sticks unsalted butter room temperature
  • 2 cups sugar
  • 4 large eggs room temperature
  • 3 tbsp finely grated lemon zest about 3 lemons
  • 4 tbsp fresh lemon juice
  • 1 tsp pure vanilla extract
  • 1 cup milk
  • 1 cup fresh blueberries

Blueberry Buttercream Ingredients:

  • 1 cup 2 sticks unsalted butter room temperature
  • 2 lbs confectioners sugar
  • 1 tsp pure vanilla extract
  • 1/2 cup of blueberry puree
  • 1 tbsp lemon juice


Lemon Blueberry Cupcakes Directions:

  1. Preheat oven to 325 degrees. Prepare standard cupcake pan with liners.

  2. In a separate bowl, mix flour (or flour + baking powder) and salt. Set aside.
  3. In the bowl of your stand mixer, cream together butter and sugar until fluffy. I prefer the paddle attachment for this recipe.
  4. Add eggs one at a time until combined. Once mixed, add zest, lemon juice, and vanilla extract. Mix until incorporated. Use spatula to scrape sides of the bowl until batter is well combined.
  5. With your mixer on slow (to avoid a flour cloud), add the flour mixture one quarter at a time. 

  6. Slowly add a cup of milk. Mix until combined.
  7. Gently fold in blueberries using a spatula.

  8. Add batter to cupcake pan until tins are 3/4 full. Bake for 20-25 minutes.

Blueberry Buttercream Directions:

  1. To make blueberry puree: place 1 cup of blueberries in your blender or food processor.
  2. Cream butter in your stand mixer using paddle attachment until fluffy.
  3. Add 1/2lb. of the confectioner's sugar (1/4 of the bag). Mix until creamy.
  4. Next, add vanilla extract until combined. Add another 1/2lb of the confectioner's sugar. Mix until grains of frosting begin to form.
  5. Add 1/4 cup of the blueberry puree and mix until creamy. Alternate between the remaining confectioner's sugar and blueberry puree until you achieve the desired consistency. It is okay to not use all of it! You are looking for a peanut butter consistency for optimal frosting.
  6. Once cupcakes are cooled, frost using the tip of your choice and a frosting bag.
