Vegan Key Lime Pie Bars
These bars nail that tangy-sweet balance without any dairy or eggs. The cashew-based filling gets seriously creamy after a good chill.
You’ll get clean slices and zero guilt about seconds.
Cashews Create the Magic
Soaked cashews blend into silk when you give them enough time. Four hours minimum, but overnight works better. Hot water speeds things up if you’re impatient. The longer soak means less blending time and smoother texture. Skip this step and you’ll taste gritty bits in every bite.

Highly Recommended
Press That Crust Down Hard
Your graham cracker base needs serious compression or it’ll crumble when you cut. Use the bottom of a measuring cup and really lean into it. Work from center outward, then press the edges up slightly. A loose crust means messy bars that fall apart on your plate.
Temperature Controls Everything
Room temperature coconut cream blends smoothly while cold cream stays chunky. Let your lime juice come to room temp too – it mixes better with the cashews. But chill your finished bars completely before cutting. Two hours minimum, though overnight gives you perfect slices.
Getting Clean Bar Cuts
- Warm your knife under hot water and wipe dry between each cut for professional-looking edges.
- Regular limes work fine if key limes aren’t available – just use 2 tablespoons less juice.
- Freeze bars for 30 minutes before cutting if they seem too soft after chilling.
Frequently Asked Questions
Will regular lime juice work instead?
Absolutely. Regular limes are less tart, so your bars will be slightly sweeter. The texture stays exactly the same.
How long do these keep in the fridge?
Five days covered tightly. The lime flavor actually gets better after the first day as everything melds together.
Do I need to soak cashews that long?
Four hours minimum for smooth blending. If you have a high-powered blender, you might get away with two hours.
