In a large bowl, beat together the monkfruit and softened butter until smooth and creamy.
Add in the egg and vanilla and beat until well combined.
In a small bowl, mix together the flour, cornstarch, baking powder and salt. Then, stir it into the butter mixture until it forms a dough.
Line a small plate with parchment paper and press 1/2 cup of the cookie dough onto it, about 1/4 inch thick. It doesn't need to be perfect. Place the plate into the freezer.
Press the remaining cookie dough flat into the bottom of an 9 inch spring form pan, and slightly up the sides, and bake until the edges are golden brown, about 20 minutes. Then, let cool to room temperature for 5 minutes and then place refrigerate for 10 minutes to really set the crust. Reduce the oven to 325 degrees.
To make the cheesecake:
While the crust sets in the refrigerator, beat together the softened cream cheese and monkfruit JUST until combined. You don't want to add in too much air.
Add in the Greek yogurt, eggs and vanilla and beat just until combined and the cream cheese is smooth.
Once the crust has cooled for 10 minutes, pour the cheesecake over top and gently smooth out.
Remove the reserved 1/2 cup of cookie dough from the freezer and crumble it in small pieces all over the top of the cheesecake. You will cover the majority of the cheesecake.
Bake until the cheesecake rises slightly and the outsides are set, and just a small circle in the center of the cheesecake is still jiggly, about 1 hour to 1 hr and 5 minutes. Then, turn off the oven, crack open the oven door and leave the cheesecake in there for 15 minutes.
Remove the cheesecake from the oven, GENTLY run a very sharp knife around the sides of the pan. Then let the cake stand until it reaches room temperature. Once it's at room temperature, cover and refrigerate for at least 6 hours to overnight.
After it's set, slice and DEVOUR.
*I used Pillsbury brand and highly recommend using the same to ensure accurate results. Also, please weigh your flour for the same reason as gluten free baking can be tricky.
