Ingredients:

How to Make Keto Peanut Butter Cookies
Step 1: Preheat the Oven
Preheat your oven to 325°F (165°C). This ensures that your cookies bake evenly from the start.
Step 2: Prepare Your Dough
- If your nut butter isn’t easily stir-able, gently heat it until runny.
- In a mixing bowl, stir together the dry ingredients: almond flour, powdered erythritol, salt, and baking soda.
- Add in the warm nut butter and milk. Stir until a dough forms.
Step 3: Shape the Cookies
- Roll the dough into balls about 1 inch in diameter.
- Flatten each ball into thick cookies on the baking sheet.
Step 4: Bake the Cookies
Place the cookies on the center rack of the preheated oven. Bake for 10 minutes. They should be taken out when still slightly undercooked as they will firm up as they cool.
Step 5: Cool Completely
Let your cookies cool completely on the baking sheet. Enjoy them fresh or store them in an airtight container for later!
