Key Lime Pie Cupcakes

For last month’s book club I had to make a southern food to fit the theme of the night. Whenever my family goes to Florida (though it’s been many years for me) we make a point to “test out” the key lime pie at basically every restaurant we go to. We are always on the search for the best one, though none are bad.

I thought I should try making key lime pie cupcakes. Please note – I understand that in no way should this recipe be called “key lime” maybe I should just name it “lime cupcakes” but for some reason that doesn’t sound appetizing to me. Take a look at my version of super simple key lime pie cupcakes.

Step 1

Preheat your oven to 350 degrees and line your muffin tin with baking cups.

Step 2

In a medium-sized bowl beat together the cake mix, milk, eggs, melted butter, and 1 tablespoon of lime zest.

Step 3

Pour the cake batter into the baking cups filling each about 2/3 full.

Step 4

Bake for approximately 15 minutes or until a toothpick comes out clean.

Step 5

Make the filling by beating together the cream cheese, sweetened condensed milk, and lime juice.

Baking Tip: If your store has key lime juice buy it instead of regular lime juice.

Step 6

Use your cupcake corer to remove the center of each cupcake. Eat the cake that is removed – just kidding, you don’t have to but why not?

Step 7

Fill with the cream cheese filling (I just use a spoon to do this step).

Baking Tip: You will most likely have extra filling left over. I like to dip graham crackers in it to have as a snack throughout the week.

Step 8

Make the whipped cream by beating the heavy whipping cream until soft peaks form. Then add the powdered sugar and vanilla until stiff peaks form.

Baking Tip: Use clear vanilla extract if you want your whipped cream to look white. I always forget.

Pipe the whipped cream on top of each cupcake. I used this tip for my cupcakes but you can certainly frost the cupcakes however you wish.

Step 9

Make a crumbly topping by mixing together the melted butter, sugar, and graham cracker crumbs. Sprinkle over the whipped cream.

Step 10

Garnish with a lime triangle and lime zest. Store in the refrigerator.

      Thank you for bringing this to my attention. I have now fixed it. The back of the cake mix box says to use three eggs but I almost always use one more egg any type I use a boxed cake mix. For this recipe I used a total of four eggs.
