3-Ingredient Peanut Butter Cookies — The Easiest Cookie You'll Ever Bake

Some cookies ask for creamed butter, chilled dough, a list of dry ingredients measured just right. This one asks for a bowl, a spoon and three things you probably already have: peanut butter, sugar and an egg. No flour, no butter, no waiting around — just twenty minutes from start to finish.

Why This Recipe Works

Peanut butter does double duty here, standing in for both the fat and the flour that a normal cookie dough needs. That's what makes this method so forgiving: there's no gluten to overwork, no butter temperature to worry about. The one thing that matters is pulling the cookies from the oven while the centers still look a little underdone — they firm up fully as they cool on the hot pan, which is exactly what keeps them soft instead of dry.

What Goes Into It

Just three ingredients: creamy peanut butter, granulated sugar and one egg to bind it together. The classic fork crisscross on top isn't just decorative — it started as a practical way to flatten the thick dough so it bakes evenly all the way through.
