  • 1 tablespoon cornstarch To thicken the filling.
  • 1 tablespoon water For the cornstarch slurry.
For the Lime Cupcakes
  • 2 cups all purpose flour
  • 1 tablespoon baking powder
  • 1/2 teaspoon salt Enhances flavor.
  • 1/2 cup butter At room temperature.
  • 1 cup sugar
  • 3 large eggs At room temperature.
  • 1/2 cup milk or buttermilk
  • 1 tablespoon lime zest Freshly grated.
  • 2 tablespoons lime juice Freshly squeezed.
  • 1 teaspoon vanilla extract
For the Lime Frosting
  • 1/2 cup butter At room temperature.
  • 2 cups powdered sugar
  • 1 tablespoon lime zest Freshly grated.
  • 2 tablespoons lime juice Freshly squeezed.
  • 1 pinch salt

Method
 

Preparation
  1. Make the blackberry filling first by cooking blackberries and sugar in a small pot over medium heat. Once they begin to break down, add lime juice.
  2. Stir in a cornstarch slurry (cornstarch mixed with water) and cook for another minute or two until thickened. Let cool completely.
Baking the Cupcakes
  1. Preheat your oven to 350°F (175°C) and line a cupcake pan.
  2. Cream the butter and sugar until fluffy, then mix in the eggs one at a time.
  3. Add lime zest, lime juice, and vanilla, and mix to combine.
  4. In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add this mixture and the milk to the wet ingredients, starting and ending with the dry ingredients.
  5. Scoop the batter into the cupcake liners about two-thirds full and bake for 18 to 20 minutes. Let them cool completely.
Filling and Frosting
  1. Use a small knife or cupcake corer to remove the center of each cupcake and spoon in the cooled blackberry filling.
  2. To make the frosting, beat butter until smooth, then gradually add powdered sugar. Mix in lime zest, lime juice, and salt. If the frosting is too thick, add a splash of milk.
  3. Pipe or spread the frosting onto the cooled cupcakes. For a decorative touch, add a swirl of leftover blackberry filling on top.

Notes

Ensure ingredients are at room temperature for best mixing results. Do not overmix the batter to avoid tough cupcakes. Taste and adjust the sweetness of the blackberry filling as needed.
