How to Make Keto Key Lime Pie

Step 1: Make the Crust

In a bowl, mix almond flour, shredded coconut, sweetener, melted butter, and vanilla extract until it resembles wet sand. Press the mixture firmly into a pie dish, making sure to create an even layer. Pop it in the fridge to chill while you whip up the filling.

Step 2: Whip Up the Filling

Beat the sweetener and cream cheese together in a big bowl until smooth and fluffy. Add the key lime zest, key lime juice, and vanilla extract, beating until combined well. The smell alone will have you digging in!

In a separate bowl, beat the heavy cream until stiff peaks. Fold it lightly into the lime mixture so that it does not lose its lightness and airiness. For a more firm texture, dissolve the gelatin in a tbsp of warm water and stir it in.

Step 3: Assemble & Chill

Pour the creamy filling into your chilled crust, smoothing out the top with a spatula (or your spoon if you’re feeling impatient). Cover and refrigerate for at least 4 hours, but overnight is even better for that perfect slice!

Step 4: Whip Up That Topping

Just before serving, whip the sweetener and heavy cream until light and fluffy. Spread or pipe onto pie and sprinkle with additional lime zest. Slice, serve, and get ready for the rave reviews to roll in!

FAQ

Can I use bottled lime juice instead of fresh?
Technically, yes, but fresh key limes give the best flavor! Regular limes work too if key limes aren’t available.

What can I use instead of almond flour?
Crushed pecans or coconut flour (adjusting for absorbency) make great alternatives.

How do I make it dairy-free?
Use coconut cream instead of heavy cream and a dairy-free cream cheese alternative!

What if I like my keto key lime pie a little sweeter?
Just add an extra tablespoon of sweetener to the filling! No judgment here—sweet tooths unite.

Tips & Variations

• Add even more lime zest for an extra tangy kick.
• Swap the crust for a toasted coconut base for a tropical twist.
• Sprinkle some crushed pecans on top for a little crunch action.
• Turn it into bars by pressing the crust into an 8×8 pan instead of a pie dish.
• Want a fancy touch? Pipe extra whipped cream around the edges before serving.
