Peanut butter, sugar, an egg, and chocolate chips: that is the whole list, and it is four things, not three. What follows is the recipe that circulates as a "3 ingredient chocolate chip cookie" — the three-ingredient peanut butter base is real, and chocolate is the fourth thing that goes into the bowl.
Four ingredients, counted honestly
The peanut-butter base contains peanut butter, sugar and one egg. Adding chocolate chips makes four ingredients. Optional salt, vanilla or other mix-ins increase that count further.
Each ingredient explains the texture. Peanut butter supplies the fat and the protein, which is why there is no butter here and no flour. Sugar dissolves as they bake, which helps keep the middles soft and gives the edges something to set against. The egg holds everything together and adds the moisture that turns a stiff paste into scoopable dough.
What you need
Four ingredients, for roughly 18 cookies at this size:
- Creamy peanut butter — 1 cup (256 g). A no-stir style is the most predictable. If yours is natural, stir the oil back in before you measure; dry, separated peanut butter is a common reason these cookies crumble.
- Granulated sugar — 1 cup (200 g), or 3/4 cup (150 g) for a less sweet cookie. Packed brown sugar works too.
- One large egg — about 50 g without the shell. Room temperature if you have time.
- Chocolate chips or chopped chocolate — 1/2 cup (85 g), plus a small handful for pressing on top.
Optional extras — additional ingredients, not part of the four: 1/2 teaspoon vanilla extract, a pinch of fine salt, and flaky salt for the tops. You will also want a medium bowl, a sturdy spoon, a rimmed baking sheet, parchment paper, and a 1.5-tablespoon scoop.
How to make them
1. Mix the peanut butter, sugar, and egg
Stir the peanut butter, sugar, and egg together with the spoon, adding the vanilla and fine salt if you are using them. It looks sandy at first, then comes together into a thick, glossy paste in about a minute.
2. Stir in the chocolate chips
Fold in the 1/2 cup of chips with a few strokes. If you are pressing chips onto the tops later, set that small handful aside now.
3. Chill the dough for 30 minutes if you can
Cover the bowl and refrigerate it for about 30 minutes, or up to two days. Cold dough spreads less, so the cookies tend to bake up thicker with softer middles. In a hurry, expect slightly thinner cookies.
4. Heat the oven and set up
Heat the oven to 350°F (175°C) with a rack in the middle. Line a baking sheet with parchment. Scoop 1.5-tablespoon balls, set them about 2 inches apart, and press two or three reserved chips onto each one.
5. Bake for 10 to 12 minutes
Treat 10 to 12 minutes as a starting guide and check for doneness rather than watching the clock: edges set and barely golden, centers still puffed, pale, and slightly underdone. Turn the pan halfway through if your oven runs uneven.
6. Let them set on the pan
Leave the cookies on the pan for 5 minutes before you move them; that rest is what lets a fragile, puffy cookie firm up enough to lift.
What to expect
Expect edges that are pale gold and set, a middle that still looks a little puffy, and a few shallow cracks on top. Warm, they are likely to bend before they break; cooled, they tend to stay soft with a gentle chew and a lightly crisp rim.
With no flour and no butter, these are tender and a little dense — closer to a soft peanut butter cookie than to a crisp, bakery-style chocolate chipper. For a crisper result, bake them 1 to 2 minutes longer.
Troubleshooting
What happened | Why it happens | What to do |
|---|---|---|
Cookies spread into flat discs | Warm dough or separated peanut butter | Chill the dough, stir natural peanut butter before measuring, and cool the pan between batches |
Dough is crumbly and will not hold | Cold, dry peanut butter, or a little too much sugar | Knead in a teaspoon of water; measure by weight next time |
Cookies taste dry or hard | Baked past the soft-center stage | Check them at 10 minutes while the middles still look underdone |
Variations that stay simple
Brown sugar cookies. Swap the granulated sugar for 1 cup packed light brown sugar (200 g) for a softer, more caramel-like result.
Mix-ins. Chopped toasted nuts, white chocolate, or dried cherries all work; keep the total to about 3/4 cup.
Make ahead, storage, and freezing
Dough in the fridge: covered, up to two days; bake from cold, adding a minute.
Baked cookies: airtight at room temperature for four to five days.
Frozen dough: freeze scooped balls, then bag for up to three months. Bake from frozen at 350°F (175°C), adding 2 to 3 minutes.
Because the dough contains a raw egg, do not taste it before baking. See the FDA egg and raw-dough guidance.
Questions that come up
Are these cookies gluten free? Only if every package is certified gluten free. These four ingredients contain no wheat, but labels vary, so check the packages if it matters.
Do I really have to chill the dough? No. Chilling mainly controls spread, so without it you get slightly thinner cookies.
How long do they stay soft? Four to five days in an airtight container, and longer in the freezer.
If you want to keep baking
If this batch disappears quickly, there are more simple formulas to try. Easy Cookie Recipes With Few Ingredients: 5 Simple Formulas sorts cookies by the base that does the work — nut butter, shortbread, coconut, and meringue — and each one needs only three to five ingredients. For a softer, more neutral cookie to compare against this one, the Drop Sugar Cookie Recipe uses a 30-minute chill and the same pull-early habit.
