Recipe Ingredients & Mental Health Benefits

  • Peanut butter or another nut butter
  • Honey
  • Vanilla extract
  • Salt
  • Rolled oats (old-fashioned oats)
  • Chopped nuts your choice
  • Mini semi-sweet chocolate chips
  • Flax meal

While these squares are not low in calories, they are high in fiber, protein, B vitamins, folate, vitamin E, iron, magnesium, selenium, and zinc. Most of these are antidepressant nutrients according to research. I also included flax meal to increase the amount of omega-3 fats in the squares. Consuming foods rich in these nutrients supports not only physical health but also mental health.

Tips, Variations, & Substitutions

Feel free to experiment and make these oatmeal peanut butter squares truly your own. They’re forgiving enough for novice bakers and versatile for the experienced to play with. Remember, the key to these squares is combining flavors you love with nutritious ingredients.

  • Cut each square in half to make 18 bars or in quarters to make 36 mini squares, if desired.
  • For an added twist, try incorporating different mix-ins, such as dried fruits, seeds, or different nuts.
  • If you have a peanut allergy, try almond butter, sunflower seed butter, or pumpkin seed butter.
  • For a vegan-friendly version, substitute maple syrup or agave nectar for the honey.
  • Substitute chia seeds for the flax meal if desired. They still provide those valuable omega-3 fats.

Oatmeal Peanut Butter Squares FAQ

How do I store the oatmeal peanut butter squares? Can I freeze them?

I love to make these on the weekend and store them in the refrigerator in a sealed container. Then they are ready to grab and go. I have also frozen the squares. Cut them to your desired size, separate them with wax paper, and place them in an airtight container or freezer bag. When you’re ready to eat them, thaw them at room temperature or in the refrigerator before eating.

Are these oatmeal peanut butter squares gluten free?

Yes, because oats are gluten free, you can enjoy these scrumptious squares without any worries. While oats are naturally gluten-free, they are sometimes processed in facilities that handle gluten-containing grains, which can lead to cross-contamination. For those with celiac disease or a severe gluten intolerance, use oats that are certified gluten-free just to be sure.

Can I use quick oats instead of rolled oats?

Yes, you can use quick oats in place of rolled oats for this recipe. Keep in mind that quick oats have a finer texture and may make the squares a bit denser. They also absorb moisture faster, so you might need to adjust the wet ingredients slightly for the perfect consistency.
