About this recipe
These homemade easy no bake peanut butter oatmeal cookies meet all my requirements (easy, quick and delicious!) and that’s why I’m sharing the recipe with you. You can make a big batch of these and enjoy them for the whole week! Just like my peanut butter oatmeal raisin cookies, these also keep well.
And let me let in a little secret here, these are actually no bake healthy oatmeal cookies without sugar. I know, crazy. But healthy can taste good, especially if it’s a cookie! Also, it’s naturally gluten free and dairy free as well!

Ingredients and substitutions
- Peanut butter: You can use creamy or chunky peanut butter for this recipe.
- Oatmeal: I always use quick oats to make no bake oatmeal cookies because they give a better texture to the cookies. As for Rolled oats (old fashioned) , since they’re not going to be baked, the texture might end up being a bit hard in the end.
- Maple syrup: I love the flavor of maple syrup in these cookies. However, honey or agave would work, too.

Instructions
- Place the peanut butter in a small sauce pan over medium heat and stir until heated through and soft. You can also heat the peanut butter in the microwave in 10 minute intervals.
- Add maple syrup and oatmeal to the sauce pan and stir to combine.
- Let cool for five minutes and then scoop cookies and chill in the fridge.

Variations
- Nut butters: Use almond butter, cashew butter or mixed nut butter instead of peanut butter.
- Chocolate: Add one tablespoon cocoa powder to the peanut butter mixture and add one tablespoon extra maple syrup.
- Nuts: Add 1/2 cup chopped walnuts, pecans or almonds to the cookies.
- Chocolate chips: Add 1/2 cup chocolate chips to the batter before scooping.
