Description

Vegan Oatmeal Peanut Butter Cookie Bars (GF): the best salty & sweet oatmeal cookie bars, with chewy, crispy edges, chopped peanuts and major Peanut Butter flavor! Gluten-Free, Dairy-Free, Refined Sugar-Free.


Ingredients

Scale

Dry Ingredients

  • 1 cup gluten free rolled oats
  • ¼ cup gluten free oat flour – if using homemade oat flour, make sure it’s finely ground and not coarse*
  • 2 tablespoons ground flaxseed
  • 1 teaspoon ground cinnamon
  • ¼ teaspoon salt

Wet Ingredients

  • 2 tablespoons melted coconut oil
  • ¼ cup + 2 tablespoons unsalted, natural creamy peanut butter or homemade peanut butter
  • 3 tablespoons pure maple syrup
  • 3 tablespoons coconut sugar
  • 1 teaspoon pure vanilla extract

Add-ins

  • ½ cup peanuts, finely chopped

Instructions

  1. Preheat oven to 350°F. Line an 8-inch square baking pan with parchment or greased foil. Set aside.
  2. In a large bowl, whisk together all of the dry ingredients: oats, oat flour, flaxseed, cinnamon and salt.
  3. In a medium bowl, whisk together the wet ingredients: coconut oil, peanut butter, maple syrup, coconut sugar and vanilla.
  4. Pour the wet mixture over the dry mixture. Using a rubber spatula, stir and fold until well mixed. Fold in peanuts, if using.
  5. Pour this mixture into the prepared baking pan. Using the rubber spatula, spread into an even, tightly-packed layer.
  6. Bake for 16-24 minutes, until golden brown on top. Mine took 20 minutes. Place baking pan on a cooling rack, allowing to cool for 30 minutes. Then, pinch the edges of parchment/foil and lift bars onto the rack to continue cooling completely (about 1-2 hours). Slice into 16 bars. Enjoy!

Notes

  • A Note on Homemade Oat Flour: *If using homemade oat flour, make sure to blend the flour until very fine and sift the flour to remove coarse bits of oats that could create grainy bars.
  • Where to Buy Ingredients: Gluten Free Rolled Oats | Gluten Free Oat Flour or try Homemade Oat Flour | Ground Flaxseed | Coconut Oil | Natural Peanut Butter | Pure Maple Syrup | Coconut Sugar
  • Storing Notes: Store in an airtight container for 1-2 weeks. I like using these reusable zip bags to keep the bars fresh.

      I haven’t tried it myself, but some readers have used honey and brown rice syrup in other recipes with good results. If you do try it, let me know how it goes!

    I have made these a couple times now and love them as a granola-bar cookie type snack. Good with some shredded coconut. Drier than the breakfast balls, and freeze well for a quick snack.
