Not a common pairing, chocolate and lime… Let me tell you, it’s divine! Here, the subtle chocolate from the cookie crust is a great introduction to this combo. A bright, fresh and creamy lime filling, floating on a super crunchy chocolately layer… one bite and you’ll be hooked!

** This post is part of the special Key Lime KIDS series, designed to help kids during these challenging times by providing entertaining and engaging activities for families to do together at home. RECIPES WILL BE ENJOYED BY KIDS AND ADULTS, ALIKE.

You all know, citrus and especially ZEST (❗) is one of my favorite ingredients. It amplifies flavor and brightens up dishes like nothing else. These lime bars are inspired by a family favorite dessert treat, the lemon bar –  but this is NOT your standard recipe, it’s even easier!

It’s funny, when they first came out of the oven, my husband was really thrown off that they were yellow! I assured him they were lime flavored, but that the egg yolks give them their sunny hue.

Separating Egg Yolks from Whites

Lucy helped me demonstrate how to separate eggs for this episode of Key Lime Kids, and as you’ll see in the video, sometimes the yolk breaks. It happens to us all.

For this recipe, it’s not a big deal if some egg white gets in your yolks. (And here we are only using the yolks- the whites are set aside and can be used in another recipe like my Forgottens or Chocolate Pavlova).

Yolk in your egg whites… well that’s an entirely different story! Even the tiniest bit of egg yolk will keep an egg white recipe from getting fluffy. If there is a break, I suggest using the whites plus broken yolk for scrmbled eggs or french toast, or as we did later that night, a batch of chicken schnitzel. Yum!

What happens if the store doesn’t have Key Limes?

If you can’t find key limes (and I couldn’t this time! ?) you can use the juice of regular limes. Just be sure to add a little of the lime zest to amp up the flavor, as noted in the recipe.

Key Lime Bars with Chocolate Crust

Prep Time20 mins

Cook Time15 mins

Chill Time2 hrs

Servings: 16 Bars

Ingredients

For the crust:

• 3 cups ground chocolate cookies (200 grams), I used one box of Annie’s Chocolate Bunnies
• 1 stick unsalted butter melted
• 2 tablespoons light or dark brown sugar

For the filling:

• 1 14- ounce can sweetened condensed milk
• ½ cup fresh key lime juice or regular lime juice plus zest from 1 lime
• 4 egg yolks

Instructions

• Begin by making the crust. Preheat your oven to 325. Line a 9 x 9” baking pan with two sheets of parchment paper so that each piece fits in the bottom of the pan and comes up two sides.
• Combine the chocolate cookies, melted butter, and brown sugar in a bowl and mix well. Press into the bottom of the prepared pan and bake for 7-10 minutes. Remove and set aside while you prepare the filling.
• Put the egg yolks in a bowl and whisk. Add the condensed milk and lime juice and zest and stir.
• Pour the filling into the crust and return it to the oven and bake another 12-15 minutes until set but still jiggly. Let cool completely, then refrigerate for 2-4 hours, or overnight, before cutting into squares. Dust with powdered sugar if desired.
