Instructions

  1. Preheat oven to 350°F (175°C). Line a 12-cup muffin pan with cupcake liners or lightly grease the cups.
  2. In a medium bowl, whisk together flour, baking powder, and salt. Set aside.
  3. In a large bowl, beat softened butter and granulated sugar until light and fluffy, about 3-4 minutes.
  4. Beat in eggs one at a time, then add vanilla extract, mixing well after each addition.
  5. Alternately add dry ingredients and milk to the butter mixture, starting and ending with dry ingredients. Mix gently until combined.
  6. Fold in key lime zest and fresh key lime juice gently.
  7. Spoon batter evenly into cupcake liners, filling about 2/3 full.
  8. Bake for 18-22 minutes or until a toothpick inserted in the center comes out clean. Cool completely on a wire rack.
  9. While cupcakes bake, mix crushed graham crackers, melted butter, brown sugar, and cinnamon in a small bowl. Set aside.
  10. Beat softened cream cheese with powdered sugar until smooth. Add key lime juice and fold in whipped heavy cream gently.
  11. Hollow out the center of each cooled cupcake about 1 inch deep using a cupcake corer or small knife.
  12. Pipe or spoon lime cream filling into each hollowed cupcake, topping flush with the surface.
  13. Sprinkle graham cracker crumble generously over the filled cupcakes and press lightly to adhere.
  14. Refrigerate cupcakes for at least 30 minutes to set filling and topping. Serve chilled or at room temperature.
