These soft, chewy peanut butter cookies deliver all the nostalgic flavor of the classic with none of the sugar or flour. With just a handful of pantry ingredients and one bowl, they come together in under half an hour and stay perfectly keto.
Ingredients
- 1 cup natural peanut butter (unsweetened, no added oil)
- 3/4 cup almond flour (super-fine, blanched)
- 1/2 cup granulated monk fruit sweetener (erythritol blend)
- 1 large egg, room temperature
- 1 tsp pure vanilla extract
- 1/2 tsp baking soda
- 1/4 tsp fine sea salt
- 2 tbsp chopped roasted peanuts (for topping, optional)
Instructions
- 1
Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.
- 2
In a large bowl, stir together the peanut butter, monk fruit sweetener, egg, and vanilla until smooth and glossy.
- 3
Add the almond flour, baking soda, and sea salt. Mix until a thick, slightly sticky dough forms.
- 4
Roll the dough into 12 equal balls and space them evenly on the sheet. Flatten each with a fork in a crisscross pattern, pressing chopped peanuts on top if using.
- 5
Bake for 11–12 minutes, until the edges are set and lightly golden. The centers will look soft.
- 6
Let the cookies cool on the sheet for at least 10 minutes — they firm up as they cool — then transfer to a rack.
Tips & notes
- Use a natural peanut butter where the only ingredients are peanuts and salt; brands with added sugar or palm oil will throw off the carb count and texture.
- The cookies are fragile straight from the oven and need the full cooling time to set, so resist moving them early.
- Store in an airtight container at room temperature for up to 5 days, or freeze for up to 3 months.
