Peanut Butter Chocolate Chip Cookies
Soft peanut butter cookies loaded with chocolate chips — they stay soft for days.
What's going on here
This cookie's staying power is a direct consequence of the peanut butter. Staling in baked goods is largely starch retrogradation — cooked starch molecules gradually recrystallising and pushing water out, which is why a plain cookie goes hard on day two. Peanut butter's fat coats those starch granules and physically slows that reorganisation, so the crumb stays soft measurably longer than a butter-only cookie. The same fat suppresses gluten development, giving a tender cookie without needing a light hand. What you give up is spread and lift: peanut butter dough is heavy and stiff, so the recipe leans on brown sugar for moisture and keeps the flour lower than a standard chocolate chip cookie to stop it going cakey. Chips rather than chunks here, because chopped chocolate pools would compete with an already rich, dense crumb.
Ingredients
Dough
- 1/2 cupButter, softened
- 1 cupPeanut butter
- 1 cupBrown sugar, packed
- 1/3 cupGranulated sugar
- 2Eggs
- 2 tspVanilla extract
- 2 cupsAll-purpose flour
- 1 tspBaking soda
- 1/2 tspSalt
- 1 1/2 cupsChocolate chips
Instructions
Dough
- Cream the butter, peanut butter, and both sugars until light and fluffy, about 3 minutes.
- Beat in the eggs and vanilla.
- Whisk the flour, baking soda, and salt together, mix in just until combined, then fold in the chocolate chips.
Chill
- Cover and chill 45 minutes.
Bake
- Scoop into mounds on a lined sheet and bake at 175°C (350°F) until the edges are set and the centres still look soft.
- Cool on the pan 5 minutes before moving to a rack.

Exploits peanut butter's anti-staling effect properly and balances the flour down to compensate for the stiff dough. Very forgiving.

Tips for this recipe
These keep better than most
Stored airtight at room temperature these stay soft for four or five days, well past a standard chocolate chip cookie — the peanut fat slows the starch from recrystallising. A slice of bread in the tin isn't necessary here.
Cookies came out cakey
Too much flour. This dough is already stiff from the peanut butter, so an over-packed measuring cup tips it straight into cake territory. Spoon and level, don't scoop.
