On weekends, my kids love helping press the mixture into the pan. They call these their power squares and always grab a couple before heading out to school or sports.

Common Recipe Questions

Can I use quick oats instead of rolled oats?

Rolled oats provide a heartier texture, but quick oats can be used for softer squares. Adjust mixing for even coating.

Are these squares suitable for vegans?

Yes—choose maple syrup and swap in vegan chocolate chips if desired. Confirm all ingredients fit your dietary needs.

How do I make them gluten-free?

Ensure you select certified gluten-free oats, as standard oats may contain traces of gluten due to processing.

Can I replace peanut butter with another nut butter?

Absolutely. Almond, cashew, or sunflower seed butter work well for different flavors and allergens.

How long will the squares stay fresh?

Store them in an airtight container at room temperature for up to 5 days. Refrigeration extends shelf life slightly.

Can I add chocolate chips or dried fruit?

Yes, mix in 1/4 cup of mini chocolate chips or dried fruit before baking for extra sweetness and texture.
