Key Lime Pie Cupcakes

White cupcakes filled with tangy key lime mousse, topped with whipped cream cheese lime frosting and toasted graham cracker crumble

Prepare and cool a batch of White Cupcakes. Using a paring knife, cut a little cone out of the center of each cupcake. Remove the cone and cut away all but the top, leaving a small disk of cake. Fill the inside of each cupcake with Lime Mousse and top with the cake disk. Top cupcake with Whipped Cream Cheese Lime Frosting. Roll sides of frosting in Graham Cracker Crumble. Top with sliced lime or berry if desired. Refrigerate until ready to serve.



White Cupcakes


1 box of white cake mix

1 cup all-purpose flour

1 cup sugar

¾ teaspoon salt


1 cup water or milk

¼ cup oil

1 teaspoon vanilla extract

4 egg whites (or 3 eggs)

1 cup sour cream


Heat oven to 375 degrees. Place dry ingredients in a large mixing bowl and stir to combine. Add the remaining ingredients and beat on medium speed for 2 minutes, scraping bowl occasionally.


Scoop batter into cupcake pans, prepared with paper liners. Bake each pan for 18 to 20 minutes, or until toothpick inserted in middle comes out clean. Makes about 36 cupcakes.



Lime Mousse

1 (14 ounce) can sweetened condensed milk

½ cup lime juice

1 cup whipping cream

Green food coloring (optional)


Stir condensed milk and lime juice in large bowl to blend. In a separate bowl, use an electric mixer to beat whipping cream until firm peaks form. Fold whipped cream into the lime mixture and gently combine until smooth. Add a couple drops of green food coloring if desired.



Whipped Cream Cheese Lime Frosting

8 ounces of cream cheese

1 cup granulated sugar

2 tablespoons lime juice

Pinch of salt

1 ½ cup whipping cream


In a medium bowl, beat cream cheese, sugar, lime juice, and salt several minutes until smooth and glossy. (Sugar should dissolve.) In another bowl, beat whipping cream until firm peaks form. Fold into cream cheese mixture.



Graham Cracker Crumble

6 tablespoons butter

⅓ cup sugar

1 cup graham cracker crumbs


Melt butter in heavy skillet over medium heat. Mix in sugar and stir until bubbling, about 1 minute. Mix in crumbs; stir until color deepens, about 3 minutes. Turn out onto tray and cool.
