🛒 Ingredients (Makes 16 Cookies)
-
1 cup natural creamy peanut butter (unsweetened, no added sugar)
-
½ cup powdered keto sweetener (erythritol or monk fruit blend)

1 large egg (room temperature)

1 tsp vanilla extract
-
½ tsp baking soda

🥄 Ingredient Notes & Tips
Peanut Butter:
Use natural peanut butter with only peanuts (and salt). Avoid brands with added sugar or hydrogenated oils.
Sweetener:
Powdered sweetener works best for smooth texture. If using granulated, pulse it in a blender first to prevent graininess.
Egg:
Room temperature eggs blend better and create a smoother dough.
🔥 Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
Step 2: Mix the Dough
In a medium mixing bowl:
-
Add peanut butter and sweetener.
-
Mix until smooth and creamy.
-
Add egg, vanilla extract, baking soda, and salt.
-
Stir until a thick cookie dough forms.
The dough will be slightly sticky but easy to scoop.
Step 3: Shape the Cookies
-
Scoop about 1 tablespoon of dough per cookie.
-
Roll into balls and place on the lined baking sheet.
-
Flatten gently with a fork to create the classic crisscross pattern.
Leave about 1–2 inches between cookies.
Step 4: Bake
Bake for 10–12 minutes, or until the edges are lightly golden.
The centers may look slightly soft — that’s perfect. They will firm up as they cool.
Step 5: Cool Completely
Let cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack.
They will become perfectly chewy as they set.
