Key Lime Pie Cupcakes!

I love these little sunshine cakes! I started with baking a yellow cake base in a cupcake pan with colorful cupcake tins.  You can use either boxed cake mix or use your own recipe.  Traditionally, this cupcake is made with white cake but I thought yellow might be a good combination too.  Next, I filled my cupcake injector with a mixture of 1 14 oz. canned sweetened condensed milk, 1/3 cup key lime juice, & a lot of lime zest.  Mix all ingredients together and chill in the fridge...it took mine 30 mins to form a pudding type of filling and even then I left it in the fridge until I was ready to fill and serve the cupcakes.  Anyway, inject your cupcake with as much filling as you desire and pipe whipped cream (you can make it yourself or use store bought I used Sugar free Cool Whip & it turned out delicious!)  Sprinkle with smashed graham crackers (I just put two in a ziplock bag and basically beat them with the handle of my knife) and top with a fresh cut lime slice. And there you have it the perfect treat for a hot summer day!
