These mini key lime cheesecakes are my ultimate summer treat for gatherings sunny afternoons and celebratory dinners. Cool creamy tangy and completely no bake each cup captures everything I love about key lime pie but with a lighter texture and just-right size for individual indulgence.
I first made these on a warm July afternoon for a birthday picnic. Everyone loved having their very own little cup and there were no leftovers at all.
Ingredients
- Graham cracker crumbs: They create the classic buttery pie crust base Make sure the crumbs are fresh and not stale for maximum crunch
- Melted butter: Binds the crumbs together and gives the crust a delicious richness Use real butter for the best flavor
- Cream cheese: The creamy core of any cheesecake Choose full fat for smoothest texture
- Sweetened condensed milk: Adds silkiness and a subtle sweetness Check for a thick velvety condensed milk with no lumps
- Key limes: Zest and juice infuse every bite with sharp zippy flavor If you cannot find key limes regular limes are a great substitute but make sure they are juicy and aromatic
- Whipped cream: Light fluffy topping that balances the tart filling Whip your own for a fresher taste
- Lime slices: Simple garnish to make each cup look extra special Choose small unblemished limes for pretty slices
Step-by-Step Instructions
- Prepare the Crust:
- Mix together graham cracker crumbs and melted butter in a bowl using a spoon until all crumbs are moistened and clump together easily This combination should smell toasty sweet
- Press Into Glasses:
- Spoon the crumb mixture into the bottom of each small glass or jar Use the back of a spoon or your fingers to gently pack it down forming an even compact layer for the base
- Make the Cheesecake Layer:
- In a clean mixing bowl beat cream cheese with sweetened condensed milk lime zest and lime juice Keep mixing until you have a completely smooth and creamy mixture with no lumps This step ensures the filling will set well and have the right balance of tang
- Assemble the Cups:
- Spoon or pipe the cream cheese mixture on top of each crust layer Smooth the top using the back of the spoon and gently tap the cups to settle the mixture evenly
- Chill Until Set:
- Place all assembled cups in the fridge and chill for at least three hours The longer they sit the firmer and creamier the texture becomes
- Add Toppings:
- Just before serving top each mini cheesecake with a swirl of whipped cream and a fresh lime slice for a beautiful finish

The burst of lime flavor is my favorite part Each bite is creamy and tart at the same time and reminds me of visiting my grandparents in Florida and tasting fresh key limes right from their backyard tree
Storage Tips
These cheesecakes keep wonderfully in the fridge for up to three days Keep them covered to prevent the tops from drying out They are perfect to make the night before you host a brunch or party
Ingredient Substitutions
You can use digestive biscuits in place of graham crackers if needed Lemon juice works nicely for a different citrus twist and low fat cream cheese will work but the texture will be a bit lighter
Serving Suggestions
Serve chilled right from the fridge and add an extra dollop of whipped cream just before bringing them to the table These look especially pretty with a sprinkle of extra lime zest
