Ingredients
Method
- Preheat and prep: Set your oven to 350°F (175°C). Line a baking sheet with parchment paper.
- Mix the wet ingredients: In a medium bowl, whisk the peanut butter, granulated sugar, brown sugar, egg, and vanilla until smooth and glossy.
- Combine dry ingredients: In a separate small bowl, stir together the flour, baking soda, and salt.
- Bring it together: Add the dry mixture to the wet and fold until just combined. If using, fold in the mini chocolate chips. The dough will be thick.
- Portion the dough: Scoop about 1 heaping tablespoon per cookie (around 24–26 grams each). Roll into balls and space them 2 inches apart on the baking sheet.
- Flatten gently: Use your fingers or the bottom of a glass to press each ball to about 1/2 inch thick. For a classic look, make a crisscross pattern with a fork.
- Bake: Bake for 8–10 minutes, until the edges look set and the tops are slightly cracked. They should still look soft in the center.
- Cool: Let the cookies rest on the sheet for 5 minutes, then move to a rack to cool completely. They firm up as they cool.
Overeating is a pattern. This helps you fix that problem. A quick reset for cravings, snacking, and “I’ll start tomorrow” moments.
Built for busy home cooks who want real-life structure. Simple steps that fit meal prep, family dinners, and late-night snack attacks.

Ingredients
- 1/2 cup natural creamy peanut butter (well-stirred)

Why This is Good for You
- Balanced indulgence: You get that cookie fix with a controlled calorie count.
- Protein and healthy fats: Peanut butter provides plant-based protein and satiating fats that help curb cravings.
- Lower sugar than most cookies: Enough sweetness to satisfy without going overboard.
- Portion awareness: Built-in portion control reduces mindless snacking.
Pitfalls to Watch Out For
- Using oily peanut butter: If your peanut butter is separated, stir well. Excess oil makes cookies spread too much.
- Overmeasuring flour: Pack it in and the cookies turn dry.
Spoon and level for accuracy.
- Overbaking: They should look slightly underdone in the center when you pull them. They set as they cool.
- Oversized scoops: Larger cookies bump up calories fast. Keep portions consistent.
- Skipping the salt: A little salt sharpens the peanut flavor and balances sweetness.
Variations You Can Try
- Peanut butter swirl: Drizzle 1 teaspoon melted peanut butter over each cookie after baking for flair.
Adjust calories if needed.
- Dark chocolate dip: Dip half of each cookie in melted dark chocolate. Chill to set. Great for gifts—higher calories but so good.
- Crunchy peanut version: Use crunchy peanut butter for texture, or add 2 tablespoons chopped roasted peanuts.
- Oat twist: Replace 2 tablespoons of flour with quick oats for a heartier bite.
- Cinnamon or espresso: Add 1/2 teaspoon ground cinnamon or 1 teaspoon instant espresso powder for a flavor boost.
- Gluten-free: Swap the flour for a 1:1 gluten-free baking blend, or try 1/2 cup fine almond flour for a softer, richer result.
FAQ
Can I use a sugar substitute?
Yes.
A granulated erythritol or allulose blend works well. Start with a 1:1 swap, taste the dough, and adjust slightly if needed. Keep in mind that some sweeteners brown less, so watch texture more than color when baking.
Do I need to chill the dough?
Usually no.
The dough is thick and bakes well right away. If your kitchen is warm or your peanut butter is very runny, a 15–20 minute chill can help prevent spreading.
What kind of peanut butter is best?
Natural creamy peanut butter made with just peanuts and salt gives the best flavor. If yours is very oily, drain a tiny bit of oil or stir thoroughly.
Standard shelf-stable peanut butters also work and may spread a little less.
How do I keep them soft?
Don’t overbake, and let them cool on the sheet before moving them. Store in an airtight container with a small piece of bread or a marshmallow to retain moisture.
How big should each cookie be to stay near 100 calories?
Aim for about 1 heaping tablespoon of dough (24–26 grams) per cookie. This batch should yield around 12 cookies.
If you make fewer, the calories per cookie will increase.
Can I make them dairy-free?
Yes. The base recipe is naturally dairy-free if you skip the chocolate chips or use dairy-free mini chips.
Can I double the recipe?
Absolutely. Double all ingredients and bake in batches.
Keep portions consistent so the bake time and calories stay accurate.
Final Thoughts
These 100-calorie peanut butter cookies deliver big comfort in a small, smart package. They’re easy to whip up, satisfy a sweet tooth, and fit neatly into a balanced routine. Keep a batch on hand for quick snacks, or freeze the dough for fresh-baked cookies anytime.
