3 Ingredients for peanut butter cookies
Who would have thought you can make cookies with just three pantry staple ingredients! These cookies are gluten free and oh so delicious!
- Peanut butter: Use smooth peanut butter for the best results. It’s best to avoid natural peanut butter as it doesn’t contain any salt and the cookies tend to spread more and come out slightly crispier.
- Granulated sugar: Granulated sugar not only adds sweetness, but it also helps the cookies brown as the sugar caramelizes.
- Egg: Use fresh eggs. You can check if an egg is fresh placing it in a bowl of water. If it sinks it is good to use. Use free run / organic eggs if possible.
How to make 3 ingredient peanut butter cookies
Start by placing the three ingredients together in a bowl. You’ll need 1 cup of peanut butter, 1 egg and 3/4 cup of granulated sugar. You can whisk them with a whisk attachment, paddle attachment, or simply by hand with a fork or spoon. When you’re done mixing, you’ll notice the cookie dough mixture will be soft and moist.
Next, use a small ice cream scooper to scoop the cookie dough into small balls. Place them on the prepared baking sheet a least a couple inches a part.
Flatten the cookies with your hands or the bottom of a glass, then use the back of a fork to press down and create criss-cross lines. That’s the iconic look of 3 ingredient peanut butter cookies, so we gotta represent!
Bake, cool and and grab a cookie or two! They’re soft, sweet and incredibly flavorful!
Tips for making peanut butter cookies
- Customize the peanut butter cookies by adding some chocolate chips, 1/2 teaspoon of vanilla extract, an additional egg (for a softer cookie), or a sprinkle of salt on top.
- Don’t use crunchy peanut butter. I’ve tried this, and unfortunately the cookie texture becomes too crumbly. A lot of people will swear by the old fashioned cheap peanut butter jars like Skippy or Jiff. I found that the Maranatha one works well and is made with quality ingredients. What they all have in common though is they are not only made with ground peanuts. So you’re looking for something more smooth.
- Don’t over-bake the cookies. Check on them after 8 minutes, and if the edges start to turn golden, you know they’re done. And keep in mind, these 3 ingredient peanut butter cookies will continue to harden as they cool on the baking sheet.
Frequently Asked Questions
I recommend storing them at room temperature in an airtight container. They’ll easily last 5 days. If you want them to stay extra soft, try the bread trick! Basically, if you add a piece of slice bread in the cookie container, it will help the cookies stay chewy since the cookies absorb the moisture from the bread.
You can freeze the baked cookies for up to 3 months. Place them on a baking sheet in the freezer until they are completely frozen. Then transfer them to freezer bags or an airtight container. To reheat the frozen cookies, bake in a 350°F oven for 5 minutes, or until until warmed through.
Or, you can make the peanut butter cookie dough ahead of time, wrap tightly in plastic wrap, and freeze. When ready to bake, allow the dough to thaw in the fridge until you’re ready to form and bake the cookies.
These cookies will take around 10 minutes to bake and I like to start checking them at around 8 minutes. They should be firm to the touch and browning at the edges ever so slightly.
These naturally gluten-free flourless peanut butter cookies couldn’t be easier to make or enjoy! You only need three staple ingredients, which you probably already have. So, I hope you whip up 3 ingredient peanut butter cookies sometime! They’ll satisfy your craving for the rich taste of peanut butter any day.
