Step-by-Step Cooking Instructions
Pre-Cooking Prep
Preheat your oven to 325°F. Lightly grease a springform pan or line the bottom with parchment paper.
In a bowl, mix almond flour, melted coconut oil, and a small amount of honey or maple syrup. Press firmly into the bottom of the pan. Bake the crust for 8–10 minutes, then set aside to cool slightly.
Cooking Method
-
Beat cream cheese until smooth
-
Add Greek yogurt and mix until creamy
-
Beat in eggs one at a time
-
Mix in key lime juice, zest, sweetener, vanilla, and salt
Pour filling over the crust and smooth the top.
Bake for 40–45 minutes, until edges are set and the center slightly jiggles.
Turn off the oven, crack the door, and let the cheesecake cool inside for 30 minutes to prevent cracking.
Doneness or Texture Check
The cheesecake is ready when:
-
Edges are firm
-
Center jiggles slightly but isn’t wet
-
Top looks set, not browned
It will firm up more as it chills.
Resting or Final Touches
Cool completely at room temperature, then refrigerate for at least 4 hours (overnight is best).
Before serving, add extra lime zest or a light dollop of Greek yogurt if desired.
