Peanut Butter Oatmeal Cookies

by Laura

I have a sweet treat recipe for you today, just in time for the weekend. You are gonna love these peanut butter oatmeal cookies. I love a cookie that includes oatmeal. It makes me feel like I am choosing a better treat if it has oatmeal.

This cookie also has peanut butter. This makes me feel like this cookie is even better with the protein you get from the peanut butter. I don’t feel too bad when I am eating a cookie with healthier ingredients included.

These peanut butter oatmeal cookies include both brown sugar and white sugar. Brown sugar adds a chewy factor. However, the secret to these cookies is it is made with dark brown sugar. You could use regular brown sugar, but the dark version gives this cookie and added richness to the flavor.

You do need to just place 8 cookies on a baking sheet at a time. These cookies do spread so you want them to have room on the baking sheet. I have made these cookies smaller and it works good too. Just cook them a little less to compensate for the smaller size. I put 12 on a cookie sheet with the smaller size.
