Step 1

Place your butter, sweetener, vanilla extract and egg in a stand mixer or large bowl and use an electric hand mixer to combine well.

Step 2

In another bowl, whisk all the dry ingredients together. Pour half of the dry ingredients into the wet ingredients and blend until combined. Add remaining dry to wet and combine.

Step 3

Line a large baking sheet pan with parchment paper.

Step 4

Use a tablespoon or measure out 18 grams or .5 ounce of dough and roll into a ball. Place balls about 2 inches apart on sheet pan. Once all balls are made, use your thumb or a rounded 1/2 teaspoon and make an indent into the center of each cookie. Freeze for 1 hour.

Step 5

Preheat oven to 350 degrees F. Remove cookies form freezer and bake for 7-8 minutes. Remove from oven and indent the centers of the cookies again. Add 1/2 teaspoon of your filling of choice. Place bake into the oven for 1-2 minutes more. Remove from oven but do not touch until they are completely cool. Please note; if using sugar free chocolate chips, if they don't melt together enough, simply use a toothpick to swirl the chips together.

Step 6

Once cooled, you can keep them on the counter for 2-3 days, but they will stay fresher and soft and moist, if you keep them stored in an airtight container in the refrigerator for up to 7 days. You can also freeze for up to a month.
