These key lime bars are baked on top of a buttery crust and taste similar to everyones favorite lemon bars. Make a bunch of these for summer parties and potlucks!
It wasn't until I recently hd a slice of key lime pie, that I remembered how much I missed it. That creamy and tart combination makes any key lime dessert always so good.
My key lime bars follow the same steps as lemon bars but I can definitely taste the difference, I think limes are much more tart or maybe it's just the amount of lime zest I added to this recipe. I'm all about the extreme tart taste.
Tips for making these easy key lime bars
- When you press the pastry into the base of the 9 x 13 inch, make sure to craft a small lip along the sides. This will prevent the filling leaking over the sides and sticking to the pan as it bakes.
- Use an electric whisk or stand mixer to beat the sugar and eggs together to create as much volume as you can.
- You'll know the key lime bars are ready if you shake the pan gently and the center no longer jiggles.
- The bars will firm up as they cool, so let them rest for an hour before slicing them into squares.
- Line your pan with parchment paper and leave an overhang all around the pan, this will make lifting the slab out of the pan much easier.
- Use a sharp knife to slice them making sure to clean it after every couple of cuts, otherwise the filling will stick to the knife and become messy.
- Make sure to zest your limes before juicing them!
