Step-by-Step Instructions 📖
1. Preheat & Prepare
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
2. Mix the Dough
In a bowl, combine peanut butter, sugar, and egg. Stir until smooth and well incorporated. The dough will be thick and slightly sticky.
3. Scoop & Shape
Scoop out tablespoon-sized portions of dough and roll them into balls. Place them on the prepared baking sheet, leaving space between each.
4. Crisscross Pattern
Using a fork, gently press down each cookie, making a crisscross pattern on top. This helps flatten them and creates the classic peanut butter cookie look.
5. Bake to Perfection
Bake for 8-10 minutes until the edges are set. They may look soft, but they will firm up as they cool.
6. Cool & Enjoy
Let the cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack. Enjoy warm or store for later!
Pro Tips for Success ✅
- Use natural peanut butter for a stronger peanut taste, but stir well before using.
- Don’t overbake! These cookies firm up as they cool.
- If the dough is too sticky, refrigerate for 10 minutes before shaping.
- For uniform cookies, use a cookie scoop.

FAQs ❓
1. Can I use almond butter instead of peanut butter?
Yes! Almond butter or cashew butter works, but the texture may vary slightly.
2. Why are my cookies crumbly?
Natural peanut butter can make cookies crumbly; add 1 tsp of honey or maple syrup for better binding.
3. Can I make these vegan?
Yes! Replace the egg with a flax egg (1 tbsp flaxseed meal + 3 tbsp water).
4. Do I need to chill the dough?
No chilling required! However, refrigerating for 10 minutes can help if your dough is sticky.
5. What type of peanut butter is best?
Both natural and processed peanut butter work. Natural peanut butter gives a more intense flavor, while processed peanut butter provides a smoother texture.
