Mini Key Lime Pie Bites have become my go-to offering for parties birthdays or anytime I want a tangy-sweet treat that can be eaten without a fork. Their creamy filling and buttery crust appeal to everyone and they come together faster than a full-sized pie. They are always a little showstopper on the dessert table thanks to their playful size and bright flavor.
I first made these mini pies when I was in charge of dessert for a family reunion. Everyone loved them so much that now I am always asked to bring them for any get-together. Their size makes them so easy to serve and enjoy with minimal mess.
Ingredients
- Graham cracker crumbs: Bring a buttery crunch base that holds up well. Choose fresh crumbs for a toasty flavor
- Granulated sugar: Sweetens the crust and helps it brown evenly
- Unsalted butter: Is key for a rich crust rather than salty notes. Use high-quality for best results
- Fresh key lime juice: Offers the signature zingy lift to the filling. Squeeze your own if possible for the brightest taste
- Key lime zest: Contributes extra aroma and depth. Look for smooth-skinned limes for easy zesting
- Sweetened condensed milk: Provides rich creaminess and just the right sweetness. Choose full-fat for better texture
- Sour cream: Balances the sweetness with a gentle tang. Pick thick creamy varieties for luscious filling
- Large egg yolks: Provide silkiness and help the filling set. Use fresh eggs from a trusted source
- Heavy whipping cream: Whips into a soft cloud on top. Cold cream whips faster and holds better peaks
- Powdered sugar: Dissolves easily into the whipped cream for a smooth sweet finish
- Key lime zest or lime slices: Add a fun pop of color and even more citrus flair on top
Step-by-Step Instructions
- Prepare the Crust:
- Combine graham cracker crumbs and sugar in a mixing bowl and stir until combined. Pour in melted butter and mix until every crumb feels moistened and slightly sticky. Brush or spray a mini muffin tin with nonstick spray. Spoon crust mixture into each cup filling them two-thirds full then firmly press down using your fingers or the flat side of a shot glass so the base is compact and level. Bake in an oven preheated to three hundred fifty degrees Fahrenheit for seven to eight minutes until lightly golden and aromatic. Remove and let the crust cool completely so it is sturdy for the filling.
- Make the Filling:
- While the crust cools whisk together fresh key lime juice lime zest sweetened condensed milk sour cream and egg yolks in a clean bowl. Mix until the ingredients are fully blended smooth creamy and slightly thickened. Gently scoop or pour the filling into each cooled crust filling nearly to the top but not overflowing.
- Bake the Mini Pies:
- Slide the filled muffin tin back into the oven. Bake for ten to twelve minutes until the edges look set and the filling jiggles only slightly at the center when moved. The mini pies should not brown but will look glossy and puffy. Let the pan cool on a rack until room temperature so they finish setting. Then transfer to the fridge to chill for at least one hour making sure the bites are cold all the way through.
- Prepare the Topping:
- Chill your mixing bowl and beaters for five minutes before you whip the heavy cream. Pour the cream into the bowl and beat on medium speed until it starts to thicken. Sprinkle in powdered sugar while continuing to beat. Watch for stiff peaks to form—the cream should stand up on its own when the beaters are lifted but stay smooth and satiny.
- Assemble the Bites:
- When pies are completely chilled remove them gently from the muffin tin using a thin spatula or butter knife to loosen the edges. Either pipe or spoon a dollop of whipped cream onto each mini pie making sure each looks soft and inviting. Sprinkle with fresh key lime zest or top with a tiny wedge of lime for a final citrusy touch.
- Serve and Enjoy:
- Serve these mini pies cold and bright. Arrange on a pretty platter and watch them disappear fast. They are refreshing after a meal or as a sweet pick-me-up any time.

My favorite part about these pies is the punch of flavor from zest and juice. I have fond memories of my kids helping zest limes for me tearing around the kitchen with little spoons begging to lick the bowl at the end.
Storage Tips
Store mini pies in an airtight container in the fridge for up to three days. Keep the whipped cream topping separate if storing for later so it stays fluffy and fresh. If you need to make them ahead simply bake and chill the pies then top with cream right before serving for best texture.
Ingredient Substitutions
If you cannot find key limes use regular Persian limes for a similar fresh effect. For the crust digestive biscuits or vanilla wafer cookies make excellent alternatives. Greek yogurt can be swapped for sour cream if needed and you can use a dairy-free whipped topping for a lactose-free version.
Serving Suggestions
For special occasions display mini pies on a cake stand or in petite paper liners. They pair beautifully with fresh berries or mint leaves on the platter. At backyard gatherings I bring them chilled in a cooler so everyone can grab a treat straight from the tin.
