Ingredients you’ll need
Here’s a list of ingredients you’ll need to make these cookies. You can find my recipe card at the bottom of this post for the complete list with their amounts.
- Plain/all-purpose flour
- Baking powder
- Baking soda
- Cornflour/cornstarch: Helps keep the cookies soft for days.
- Salt
- Unsalted butter: Melted.
- Light brown sugar: Using more brown sugar than white sugar makes for extra chewy cookies.
- Caster/granulated sugar
- Large egg: You’ll need 1.
- Vanilla extract
- Smooth peanut butter
- Peanut butter chips: I used Reese’s.
How to make Peanut Butter Chip Cookies
To make these cookies, simply whisk together the flour, baking powder, baking soda, cornflour, and salt. Set aside.

In a separate large mixing bowl, whisk together the melted butter and sugars until combined.

Add the egg, vanilla extract, and peanut butter, and mix until combined.

Add the dry ingredients, and mix until just combined. Fold in the peanut butter chips.
TIP: If you find the cookie dough too crumbly, add milk (1 tablespoon at a time) and mix until it comes together and is easier to manage.


Roll the dough into 2-oz balls (or use a medium cookie scoop), and place onto a baking tray lined with parchment paper or a silicone mat. Bake for 10 – 12 minutes.

Allow to cool on the baking tray for 5 – 10 minutes before transferring them to a wire rack to cool completely.
The printable recipe card with the FULL list of ingredients and instructions can be found at the bottom of this post.
NOTE: For best results, I highly recommend using the gram measurements (with a digital scale), rather than the cup measurements.
Cup measurements are simply not accurate enough, and I cannot guarantee the best results if you use them.

Hi Marsha, Can salted butter be used in place of the unsalted and can nuts be added?
Marsha

Hi Pamela! If using salted butter, I would omit the additional salt. Yes, you can add up to 1 cup of chopped nuts alongside the peanut butter chips. Enjoy! :)

Thanks for the recipe! They're tasty but I wish I read the comments first.. they didn't flatten at all. I used a scale and an oven thermometer and didn't change anything. I'll try less flour next time :)
