How to Make Peanut Butter Oatmeal Bars

I almost feel silly sharing this recipe because it is so simple! With only 3-ingredients, these bars come together super quick. Just mix together old-fashioned oats, peanut butter and honey or maple syrup (either works!). Some additional add-ins that are great are ground flax or chia seeds for a boost of protein, fiber and omega-3 fatty acids- add 1-2 tablespoons. Press the dough into a glass baking dish and refrigerate for 10-15 minutes until firm. Cut into bars and store in the fridge or freezer. I topped my bars with a drizzle of dark chocolate and some salted peanuts but that is optional.

I also want to make it very clear that I am not only saying that we are the biggest peanut butter and peanut fans but really prove it! My son Oliver, who is 5 years old, chooses peanut butter for most of his snacks. The other day, I realized that he really had a lot of peanuts and peanut butter so I mentally went through what he ate that day and he had EIGHT servings of peanuts and peanut butter!!!

Our pantry is stocked with tons of these since my kids love them and they are a great source of protein, fiber and other vitamins and minerals. My son is slim and I am always looking to load him up with nutrients and peanuts are a good nutrient dense option for him.

Are peanut butter oatmeal bars healthy?

Yes! These peanut butter oatmeal bars are loaded with nutrients! Oats are high in fiber and contain some protein. Peanuts and peanut butter are loaded with protein. If you want these bars to be a little lighter, you can skip the chocolate but it is very delicious!
