* regular white flour may be used instead.

**melted butter/buttery spread or canola/avocado oil can be used instead.

  • Fresh or frozen berries can be used, as well as any type of berry you’d like if you’re not so indecisive like me. Do not thaw the berries if using frozen, and add an extra teaspoon of sugar if using fresh.
  • If you want a thicker bar, you can make these in a loaf pan instead. The cook time may be a 5-10 minutes longer.
  • Need to make them gluten-free? Simply swap out the flour for a gluten-free alternative, and use certified gluten-free oats.
