Tips and tricks for no bake peanut butter oatmeal cups:
Peanut butter to use:
Use whatever peanut butter you have on hand. Creamy peanut butter, natural peanut butter, or even crunchy peanut butter if you want a little extra crunch in these no bake treats.
If you want to use a nut butter like almond butter, cashew butter, or sunflower butter in place of the peanut butter you can!

Topping for peanut butter cups:
You can really make this no bake snack your own by adding toppings. Here are a few suggestions:
- Jelly on top to make peanut butter and jelly oatmeal cups
- Pinch of flaky sea salt if you use the chocolate over the peanut butter layer
- Mini m&m’s
- Chopped nuts
Oats to use:
I love using the old fashioned oats with this recipe because they hold their shape and mix well with peanut butter mixture, but if you only have quick-cooking oats on hand, they can work as well.
Make mini oatmeal cups:
Instead of using a baking dish, use a mini muffin tin with paper liners and press a little bit of the oat mixture into the bottom of the liner and then follow the rest of the recipe as written.
