Heat your oven to 350°F. Line two baking sheets with parchment paper.
Using an electric mixer, beat together the butter, oil, Sukrin Gold, and 1/2 cup of granular erythritol in a large bowl until creamy.
Next, beat in the egg and vanilla extract for 1 minute.
In a separate medium bowl, mix together the almond flour, xanthan gum, baking soda, and salt.
Slowly add the dry ingredients into the wet ingredients and beating until just combined.
Gently stir in the chocolate chips.
Use a small cookie scoop, to place 1 tablespoon of dough at a time onto the parchment-lined baking sheets, spacing them at least 2 inches apart. (You can also just use your hand to roll the dought into a ball.)
In a small bowl, heat the peanut butter and the remaining 1/4 cup granula erythritol in the microwave for 30 seconds and stir to combine.
Use a spoon to scoop out 1 teaspoon of dough from the top of each cookie ball and fill it with 1 teaspoon of the peanut butter mixture.
Place the scooped out cookie dough back on top of the peanut butter mixture.
Bake for 10-12 minutes or until the edges start to brown.
Allow the cookies to cool before removing them from the baking sheets.
