Step 1

Preheat the oven to 350 degrees.

Step 2

In a mixing bowl, beat together the egg, sugar substitute, baking powder and vanilla for about a minute.

Step 3

Add the peanut butter and water and beat together.

Step 4

The mixture will be pretty dry; just make sure the peanut butter is blended in with the other ingredients.

Step 5

Measure out a heaping teaspoon of batter for each cookie and place on a baking tray that has been sprayed with non-stick cooking spray or lined with parchment paper.

Step 6

Then using a fork, make indentations into each cookie. Spray the fork with cooking spray so it doesn't stick to the cookie.

Step 7

Bake 12 - 15 minutes until cookies feel firm and are slightly browned.

Step 8

Transfer the cookies to a baking rack and cool.
