Pin It These lime bars showcase a zesty, fresh lime filling balanced by a rich, buttery graham cracker crust. The mixture is baked until set, then chilled to achieve the perfect texture. With subtle notes of lime zest and optional festive green tint, they make an eye-catching and refreshing treat. Dusting with powdered sugar and garnishing with thin lime slices adds a touch of elegance, ideal for holiday gatherings or any occasion craving a bright, sweet dessert.
My roommate burst into the kitchen last March 17th, eyes wide: we needed something green for the party in twenty minutes. I scrambled through the pantry, found graham crackers and a bag of limes, and threw together what I hoped would work. People hovered around that pan all night, asking for the recipe.
Last summer I made these for my nieces birthday, and she kept sneaking back to the fridge. When I caught her with lime zest on her chin, she just grinned and said the green ones taste better than the yellow lemon bars I usually make.
Ingredients
- Graham cracker crumbs: Fresh crumbs work better than store bought, they hold together beautifully
- Salted butter: The salt deepens the crust flavor and keeps it from tasting too sweet
- Sweetened condensed milk: This is what creates that silky, custard like texture we love
- Egg yolks: Room temperature yolks whisk in more smoothly and prevent curdling
- Fresh lime juice: Bottled juice never gives you that bright punch you get from squeezing
- Lime zest: The oils in the zest carry all the aromatic intensity
Instructions
- Preheat your oven and line the pan:
- 350F works perfectly, and parchment overhang makes lifting so much easier later
- Mix the crust ingredients:
- Stir until the crumbs look like wet sand, they should hold together when you squeeze a handful
- Press the crust into the pan:
- Use the bottom of a measuring cup to press it flat and even, this prevents thin spots
- Bake the crust:
- Ten minutes is enough, you want it golden and fragrant, not dark or crispy
- Whisk the filling:
- Take your time here, whisk until completely smooth to avoid little white specks of egg
- Pour and bake again:
- The center should still wobble slightly, like Jell-O, when you gently shake the pan
- Chill completely:
- At least an hour in the fridge makes cutting clean squares so much easier
- Dust and serve:
- Powdered sugar right before serving keeps it from absorbing into the bars
Pin It These showed up at every family gathering last year. My dad waits by the oven now, asking if the lime bars are done yet.
Getting The Right Green Color
Two drops of food coloring is plenty, any more and it looks artificial. The natural lime zest already gives you that gorgeous pale green tint.
Making Them Ahead
These actually taste better after sitting overnight, the lime flavor deepens and the texture firms up nicely.
Serving Ideas
These work for everything from birthdays to holiday parties.
- Serve with Irish breakfast tea for a cozy afternoon treat
- Pair with a stout beer for a grown up dessert course
- Cut them smaller for bite sized party appetizers
Pin It Hope these bring a little brightness to your kitchen. The green color is just a bonus.
