how to make Key Lime Pie Cupcakes
Ingredients:
- ½ cup granulated sugar
- ¼ cup bottled Key lime juice
- 1 large egg
- 1 egg yolk
- 2 Tbsp salted butter, cut into pieces and chilled
- 1 (15–16 oz.) box white cake mix (plus required ingredients per box, usually eggs, oil, and water)
- 1 stick (½ cup) salted butter, softened to room temperature
- 8 oz. cream cheese, softened to room temperature
- ¼ cup bottled Key lime juice
- 4 cups powdered sugar (approximate; adjust to taste/consistency)
- Graham cracker crumbs
- Thin lime slices
Directions:
-
Prepare the Key Lime Curd: In a small saucepan, whisk together sugar, Key lime juice, 1 whole egg, and 1 egg yolk. Place the saucepan over medium-low heat, stirring constantly for about 5–7 minutes, or until the mixture thickens enough to coat the back of a spoon. Remove from heat and stir in chilled butter pieces until melted. Transfer to a bowl and cover with plastic wrap, pressing it directly onto the surface of the curd. Refrigerate until cool.
-
Make the Cupcakes: Preheat the oven to the temperature indicated on your cake mix box (usually 350°F/177°C). Line two standard cupcake pans with paper liners. Prepare the white cake mix batter according to the package instructions. Fill each cupcake liner about ⅔ full. Bake for 18–22 minutes, or until a toothpick inserted into the center comes out clean. Cool cupcakes in the pan for a few minutes, then transfer to a wire rack to cool completely before filling or frosting.
-
Prepare the Cream Cheese Frosting: In a large mixing bowl, beat the softened butter and cream cheese together on medium speed until smooth (about 2 minutes). Add Key lime juice, then gradually beat in the powdered sugar on low speed. Increase to medium-high and beat until light and fluffy, adjusting sweetness or lime juice to your preference.
-
Assemble & Decorate: Once cupcakes are cool, use a small knife or apple corer to remove a small “well” from the center of each cupcake. Spoon or pipe about a teaspoon of chilled Key lime curd into each well. Pipe or spread the cream cheese frosting on top of the cupcakes. Sprinkle graham cracker crumbs over the frosting and garnish with thin lime slices (optional).
