This vibrant vegan key lime pie comes together with simple ingredients and a totally plant-based filling, yet still pulls off an authentic tangy citrus flavor and creamy texture that everyone loves. I discovered this recipe when searching for a dairy-free holiday dessert that would feel bright and festive without a lot of fuss. Since then, it has been the surprise hit at summer parties and cozy winter gatherings alike.

I first served this at a birthday where most guests were not vegan and not a single slice was left by the end of the night. If you are craving something refreshing but crave a classic dessert experience this recipe absolutely delivers.

Ingredients

  • Vegan graham crackers: for a crisp nostalgic crust look for a golden brown color and avoid brands with palm oil for a more ethical choice
  • Vegan light brown sugar: gives delicate sweetness and a touch of molasses flavor choose one that is not overly clumpy to ensure easy mixing
  • Vegan butter sticks: such as Earth Balance provide richness and help bind the crust pick unsalted so you control the final flavor
  • Sweetened condensed coconut milk: makes the filling extra creamy and sweet check brands carefully as sweetness and consistency may vary
  • Non dairy Greek yogurt: plain and unsweetened brings the tangy structure important for a custardy texture almond based works beautifully
  • Key lime juice: delivers floral and bright citrus flavor fresh Key limes are ideal but bottled can work if they are pure juice with no added sweeteners
  • Cornstarch: for thickening the filling sift before measuring to avoid lumps
  • Ground turmeric (optional): just a pinch provides classic yellow color without affecting taste look for one that smells fresh and earthy

Step by Step Instructions

08 1 pinch ground turmeric (optional, for color)

How to Prepare

Step 01

Set oven temperature to 190°C.

Step 02

Process vegan graham crackers in a blender or food processor until fine crumbs form. Transfer to a large bowl and add light brown sugar. Mix until homogeneous.

Step 03

Melt vegan butter in a small saucepan over medium-low heat and pour over crumb mixture. Stir until all crumbs are fully moistened.

Step 04

Press the crumb mixture evenly into the base and up the sides of a 23-cm pie pan or tart pan. Use a flat-bottom glass or fingers to ensure compactness and even thickness.

Step 05

Place pan on a tray and bake for 10 minutes. Remove and cool completely on a wire rack.

Step 06

In a saucepan without heat, whisk together sweetened condensed coconut milk, non-dairy Greek yogurt, and Key lime juice until smooth. Add cornstarch and optional turmeric; whisk thoroughly to eliminate lumps.

Step 07

Bring mixture to a gentle boil over medium heat, stirring constantly. After 8-10 minutes, when bubbling begins, continue to stir for an additional minute until slightly thickened. Remove from heat. If clumps are present, strain through a metal sieve.

Step 08

Pour the hot filling into the cooled crust. Smooth the surface with an offset spatula or knife.

Allow to cool at room temperature for 30 minutes. Refrigerate for approximately 3 hours, or until the filling is firm.
