Classic Peanut Butter Cookies
The fork-marked original — tender, sandy, and heavily peanut.
What's going on here
The criss-cross is not decoration, it is a fix. Peanut butter brings a large load of fat and protein but almost no water, so this dough is stiff and barely spreads — left as a ball it bakes with a raw, dense centre while the outside sets. Flattening with a fork increases surface area and cuts the thickness so the middle actually cooks. The sandy, short texture comes from peanut oil coating the flour and blocking gluten formation, the same shortening effect as in shortbread, which is why overmixing matters less here than in most doughs but overbaking matters more: with so little water there's very little margin before it goes dry. Both sugars are used deliberately — white for crisp edges and spread, brown for moisture and the molasses note that reads as more peanutty than peanut butter alone.
Ingredients
Dough
- 1/2 cupButter, softened
- 1 cupPeanut butter
conventional, smooth
- 3/4 cupBrown sugar, packed
- 1/2 cupGranulated sugar
- 1Egg
- 1 tspVanilla extract
- 1 3/4 cupsAll-purpose flour
- 1 tspBaking soda
- 1/2 tspSalt
Coating
- 1/4 cupGranulated sugar, for rolling(optional)
Instructions
Dough
- Cream the butter, peanut butter, and both sugars together until light and fluffy, about 3 minutes.
- Beat in the egg and vanilla.
- Whisk the flour, baking soda, and salt together and mix in just until combined. The dough will be stiff.
Chill
- Chill 30 minutes so the dough rolls cleanly without sticking.
Bake
- Roll into walnut-sized balls (roll in granulated sugar if you like a crisp shell), space on a lined sheet, and flatten each with a fork pressed twice at right angles.
Tip: Dip the fork in sugar between cookies and it won't stick to the dough.
- Bake at 175°C (350°F) until the edges are set and just golden. The centres should still look soft.
Tip: These have very little water in them, so they cross from tender to dry fast. Err a minute short.
- Cool on the pan 5 minutes before moving to a rack.

Tips for this recipe
Why your cookies came out dry
Peanut butter doughs have far less water than a butter-only dough, so they don't have the buffer to survive a long bake. Pull them when the centres still look underdone — they finish setting on the hot pan.
Using natural peanut butter
Stir it thoroughly first, and expect more spread and a looser dough because of the extra free oil. Adding 2 tbsp more flour and chilling an extra 30 minutes brings it back into line.
