Can I use natural peanut butter in this recipe?

It is best to avoid natural peanut butter for this recipe. Natural peanut butter separates into oil and solids, and that excess oil creates a greasy, difficult-to-handle dough that spreads too much during baking. The cookies end up thin, oily, and crumbly rather than soft and chewy. Stick to a stabilised commercial brand like Jif, Skippy, or any store brand that lists fully hydrogenated vegetable oil in the ingredients.

Can I use a sugar substitute?

Yes — granulated erythritol or a 1:1 sugar-free baking substitute both work in this recipe. The texture will be slightly crumblier than the original, and the cookies may not spread quite as much, but the flavour is still very good. Coconut sugar also works as a 1:1 swap and gives a slightly deeper, more caramel-like taste while keeping a closer texture to the original.

Why do peanut butter cookies have a fork crisscross pattern?

The crisscross fork pattern is both practical and traditional. Because peanut butter cookie dough (especially this flour-free version) is thick and dense, it does not spread on its own in the oven the way a butter-and-flour dough does. Pressing the dough flat with a fork before baking ensures an even thickness so the cookies bake through uniformly. The tradition dates back to a 1936 Pillsbury cookbook, and it has stuck ever since.

How do I make these cookies softer?

The key to a softer cookie is underbaking. Pull the cookies from the oven when the edges look just set but the centres still appear soft and slightly underdone. They will firm up as they cool on the pan. If they still come out too firm, try using brown sugar instead of granulated — it retains more moisture during baking and produces a noticeably chewier, softer result.

Can I freeze the dough or the baked cookies?

Both work well. For baked cookies, freeze individually on a parchment-lined tray until solid, then transfer to a freezer bag. They keep for up to 3 months and thaw in about 15 minutes at room temperature. For unbaked dough, roll into balls, freeze on a tray until solid, then bag and store for up to 3 months. Bake from frozen at 350°F, adding 2–3 extra minutes to the baking time.

Can I double the recipe?

Absolutely. This recipe scales up easily. Double all four ingredients and mix in a large bowl. You will need two baking sheets and will bake in two batches unless your oven is large enough to handle both at once. If baking two sheets simultaneously, rotate them halfway through for even baking. The yield roughly doubles to about 28–32 cookies depending on your scoop size.

Cook Mode Prevent your screen from going dark

Instructions

Preheat your oven to 350°F and line a baking sheet with parchment paper or a silicone baking mat. Position the oven rack in the center.
In a large bowl, mix the peanut butter, sugar, egg, and vanilla extract until smooth and fully combined.
Scoop tablespoon-sized portions of dough and roll into balls. Place them on the prepared baking sheet about 2 inches apart.
Lightly grease a fork and gently press each dough ball to flatten, creating a crisscross pattern on top.
Bake for 10 minutes, until the edges are lightly golden. The centers will look soft but will firm up as they cool. Avoid overbaking.
Let the cookies cool on the baking sheet for a few minutes, then transfer to a wire rack to cool completely.

Notes

Cookies will appear soft when removed from the oven but will set as they cool.
Do not overbake or they may turn dry and crumbly.
Store in an airtight container at room temperature for up to 4 days.
Natural peanut butter can be used, but stir well before measuring for best consistency.
