Does type of peanut butter matter?

Pure peanut butter: If you want to make this cookie healthier, I highly recommend choosing pure peanut butter. You’ll know it’s pure peanut butter because there should only be one ingredient: peanuts. Non-pure peanut butter often has extra sugar, extra oils, and preservatives.

Many pure peanut butters have oil at the top and are runnier. You can use it as is (after mixing in the oil) and it will only result in slightly crumblier cookies. Another option is placing the peanut butter in the fridge until it solidifies into thicker peanut butter.

Creamy vs crunchy: Honestly, either works! The only difference is that you’ll have some crunchy peanuts in your cookies if you use crunchy peanut butter. Personally, I’m a creamy girl though.

Does type of sugar matter?

My husband asked if we could swap maple syrup in place of the sugar and the answer is no. Liquid sweeteners such as pure maples syrup or agave nectar would just cause the batter to stay more like PB soup. The coconut sugar helps to create a thicker batter that you can actually roll into a ball for cookies.

Coconut sugar vs. white cane sugar: If you only have regular white cane sugar it’ll be fine, I just suggest cutting the amount in the recipe in half first. Cane sugar is very sweet and also highly processed. Coconut sugar is still a processed sugar but it has not gone through as much of a process to be made, so there are still some nutrients in it.

Health benefits of the cookie

You read that right, eating one of these cookies could be beneficial to your health. That being said, don’t go crazy LOL. Everything in moderation, there is still sugar in these and too much peanut butter can be a lot of calories and saturated fat.

The main source of nutrition is of course, the peanut butter. That is why I stress choosing a quality pure one. Peanut butter provides 7 grams of protein per 2 tbsp, and contains magnesium, zinc, phosphorous, and vitamin B-6. One peanut butter cookie and you’re good to go!

In addition to the peanut butter, the egg also adds protein and a list of vitamins and nutrients.
