Key Lime Pie Bars with Graham Crust Recipe (Light, Creamy & Zesty!)

True confession: I made these Key Lime Pie Bars for a girls’ night… and ended up hiding two in the back of the fridge just for me. ๐Ÿ˜…

They’re that good.

Creamy, tangy, and perfectly sweet with a buttery graham crust that tastes just like the classic version — but lightened up and made with clean, real-food ingredients. Think tropical vacation meets comfort dessert… but no processed junk, no crazy steps, and zero baking needed if you use a no-bake crust.

If you love zesty, citrusy flavors and easy make-ahead treats, this one’s for you.

 

๐Ÿ‹ Ingredients:

For the crust:

  • 1 ½ cups almond flour or crushed graham-style crackers (grain-free if needed)

  • 3 tbsp melted coconut oil or butter

  • 1 tbsp maple syrup or honey

  • Pinch of sea salt

For the filling:

  • ½ cup fresh key lime juice (or regular lime juice if needed)

  • Zest of 1 lime

  • 1 can (13.5 oz) full-fat coconut milk (just the thick cream part) or 1 cup Greek yogurt

  • ¼ cup maple syrup or honey

  • 1 tbsp arrowroot starch or cornstarch

  • 1 tsp vanilla extract

  • Optional: a few drops natural green food coloring for a classic look

To garnish:

  • Fresh lime zest or thin lime slices

  • Coconut whipped cream (optional)

 

๐Ÿฅฃ Instructions:

  1. Make the crust: In a medium bowl, mix almond flour, melted oil, sweetener, and salt until crumbly. Press firmly into a lined 8x8 pan. Chill in the fridge or bake at 350°F for 8–10 minutes if you want it toasted (optional).

  2. Make the filling: In a saucepan, whisk together lime juice, zest, coconut cream (or yogurt), maple syrup, starch, and vanilla. Cook over medium heat, stirring constantly, until thickened (about 5–7 minutes).

  3. Assemble: Pour the warm filling over the crust and smooth the top. Chill in the fridge for 4+ hours or until set.

  4. Slice & serve: Cut into bars, top with lime zest or coconut whipped cream, and enjoy that creamy zingy bite!

 

๐Ÿด Sarah’s Notes & Tips:

  • Coconut cream tip: If using canned coconut milk, chill it first and scoop out just the thick part.

  • Make it dairy-free: Use coconut cream instead of yogurt.

  • Gluten-free? Yep, just use almond flour or GF graham crackers.

  • Storage: Store in the fridge for up to 5 days. Great for prepping ahead!

 

Flavorful Conclusion:

These Key Lime Pie Bars are the perfect blend of creamy, tart, and sweet — without the sugar overload or complicated steps. I love making them when I need something refreshing, make-ahead, and pretty enough to share (or stash for yourself… no judgment here!).

Whip these up for your next brunch, backyard dinner, or sunny afternoon treat. ๐Ÿ’š
