When I need a quick sweet bite that still fits a lower-carb routine, these 3-ingredient peanut butter cookies are one of the first things I make. They come together fast, use pantry basics, and bake up soft in the center with those classic fork marks on top. They are especially handy for busy weekends, game-day spreads, or anytime you want a simple homemade treat without dragging out a long ingredient list.
Serve these cookies with hot coffee, cold milk, or a simple afternoon tea. For a game-day table, I like to set them out alongside salty snacks like mixed nuts, cheese crisps, or a fruit tray so there is a nice balance of sweet and savory. They also pack well for potlucks and tailgates since they do not need frosting or any extra fuss.
Low Carb 3-Ingredient Peanut Butter Cookies
Servings: 12 cookies
Ingredients
1 cup natural peanut butter
1/2 cup granulated low-carb sweetener
1 large egg
Directions
1. Preheat your oven to 350°F and line a baking sheet with parchment paper.
2. In a medium mixing bowl, stir together the peanut butter, low-carb sweetener, and egg until a thick, smooth dough forms.
3. Scoop tablespoon-sized portions of dough onto the prepared baking sheet, spacing them about 2 inches apart. Gently flatten each one with a fork in a crisscross pattern.
4. Bake for 10 to 12 minutes, or until the cookies are lightly golden around the edges.
5. Let the cookies cool on the baking sheet for 5 minutes, then transfer them to a wire rack to cool completely before serving.
Variations & Tips
Make them sweeter: If you prefer a more dessert-like cookie, choose a low-carb sweetener blend that measures like sugar and tastes good baked. Some blends are sweeter than others, so a small test batch can help if you are trying a new brand.
Use creamy peanut butter: Creamy peanut butter gives the most consistent texture for this simple dough. Natural peanut butter works too, but stir it very well first so the oil is fully incorporated before measuring.
Do not overbake: These cookies can go from soft to dry pretty quickly. I pull them when the edges are just turning golden, because they continue to set as they cool on the pan.
Easy add-ins: If you are okay moving beyond the 3-ingredient version, a splash of vanilla extract or a few sugar-free chocolate chips can add extra flavor without much extra work.
Make-ahead tip: These cookies keep well in an airtight container for several days, which makes them great for party prep or busy workweeks when you want a quick grab-and-go treat.
