• 1 cup peanut butter (creamy or crunchy, your call)
• 1 cup sugar (white sugar is classic, but brown sugar or coconut sugar works too)
• 1 egg

That’s it. There is no flour, baking soda, or vanilla extract (unless you want to be extra). Just mix and bake.

How to Make Them

• Preheat your oven to 350°F (180°C). Line a baking sheet with parchment paper. 
• Mix the peanut butter, sugar, and egg in a bowl until smooth and thick like cookie dough. You can use a spoon, fork, or mixer. 
• Scoop dough balls (about a tablespoon each) onto your baking sheet. Flatten them a bit with a fork in that criss-cross pattern.
• Bake for 8–10 minutes. They’ll look soft in the middle; that’s precisely what you want. Let them cool on the sheet for a few minutes so they don’t fall apart when you pick them up.

FAQ 

Can I use natural peanut butter?

Yes, but stir it well first. Some brands are too oily or dry, which can mess with the texture.

Can I make these vegan?

Totally. Combine 1 tbsp ground flax and 2.5 tbsp water and let it sit for 5 minutes. The cookies will be a little softer but still tasty.

Do they freeze well?

Absolutely. You can freeze the dough or bake cookies.
