Ingredients
This quick and easy keto peanut butter cookie recipe is soft, chewy, and delicious, with no sugar or eggs required.
Ingredients:
– 1/2 cup peanut butter, or nut butter of choice
– 1 tbsp milk of choice
– 2/3 cup finely ground almond flour
– 3 tbsp powdered erythritol or powdered sugar
– 1/8 tsp salt
– 1/8 tsp baking soda
How to Make Keto Peanut Butter Cookies
Step 1: Preheat the Oven
Preheat your oven to 325°F (160°C). This ensures that your cookies bake evenly.
Step 2: Prepare Your Nut Butter
If your nut butter is not easily stir-able, gently heat it until it becomes runny. This will make mixing easier.
Step 3: Mix Dry Ingredients
In a mixing bowl, combine the following dry ingredients:
2/3 cup finely ground almond flour
3 tbsp powdered erythritol
1/8 tsp salt
1/8 tsp baking soda
Stir them well to ensure they are evenly mixed.
Step 4: Combine Wet Ingredients
Add the following wet ingredients to the dry mixture:
1/2 cup peanut butter
1 tbsp milk of choice
Stir until you form a smooth dough.
Step 5: Shape the Cookies
Roll the dough into balls and then flatten them into thick cookie shapes. Place them on a baking sheet lined with parchment paper if desired.
Step 6: Bake
Bake in the preheated oven for about 10 minutes. Remove them when they are still slightly undercooked as they will firm up while cooling.
Step 7: Cool Completely
Allow the cookies to cool completely on the baking sheet before serving. This step is crucial as it helps achieve that perfect chewy texture.
