Blueberry Lemonade Cupcakes with Lemon Curd Ingredients

Ingredient Notes

  • Lemons: I recommend using good quality fresh lemon for that extra zing and citrusy flavor.
  • Butter: Butter is used for making the cupcakes, the curd, and buttercream frosting. It needs to be unsalted butter though, and to avoid lumps, it should be softened at room temperature.
  • Sour Cream: Sour cream helps to keep the cupcakes moist.
  • Sugar: I suggest using white granulated sugar and not brown sugar for this recipe; otherwise, it will change both the flavor and color of the cupcakes and curd.
  • Flour: I have used plain/all-purpose flour.
  • Baking Powder and Baking Soda: Both baking powder and baking soda are chemical leavening agents. Baking powder does most of the leavening, while baking soda is added to neutralize the acids in the recipe and add tenderness and some leavening.

Ingredient Substitutions

  • Sour cream: You can substitute the sour cream with plain yogurt.
  • Blueberries: I think blueberries and lemons are a great combination of flavors, but you may use raspberries, strawberries, or blackberries instead.

  7. Fold in the floured blueberries.

  8. Spoon the cupcake batter into the prepared muffin cups, filling them 3/4 of the way. Bake for 15 to 20 minutes, or until a toothpick inserted in the center of the cupcake comes out clean, and the cupcakes are springy to the touch. Allow cupcakes to cool in the muffin pan for 5 minutes before transferring them to a wire rack to cool completely.

  14. Transfer the curd to a bowl and cover the surface with plastic wrap to prevent skin from forming. Set aside and let it cool.

  15. Prepare the lemon buttercream. Cream the butter, salt, and lemon zest using a standing mixer for a few minutes, then gradually sift in the powdered sugar. Add the lemon juice and mix well, then transfer to a piping bag and decorate the cooled cupcakes.

Note

  • Before you start working on this recipe, allow all the ingredients for the cupcakes and buttercream to be at room temperature. Depending on the climate, this can take anywhere from 10 minutes to 40 minutes.
  • When making cupcakes, always sift the flour, as a packed flour will lead to dry and dense cupcakes.
  • To truly enhance the flavor of this recipe, use freshly squeezed lemon juice.
  • For the lemon curd, keep the heat low and constantly whisk; otherwise, the eggs will scramble. As it cools, the lemon curd will thicken. Let it cool completely before using it. If the curd seems too thin once it is cooled, you may thicken it by adding a mixture of cornstarch and water (for each tablespoon of cornstarch, mix 3 tablespoons of water). Mix it in and heat the curd, stirring continuously until it thickens. Do not use too much cornstarch mixture as the curd will thicken once cooled.
  • If the buttercream frosting is too runny, add more powdered sugar, one tablespoon at a time, until the consistency thickens up.
  • For the blueberries, you may use fresh or frozen. If you’re using frozen blueberries, don’t thaw them first.
