With less than 10 minutes of active prep time, this easy recipe is a great way to save you time in the mornings! (gluten-free, dairy-free, vegetarian)


  • 2 medium ripe bananas, mashed (about 1 cup)
  • 2/3 cup natural peanut butter (look for kinds made with just peanuts and salt)
  • 2 large eggs
  • 1 3/4 cups Silk Unsweetened Vanilla Almondmilk
  • 2 cups rolled oats
  • 3 tbsp ground flaxseed
  • 1/2 tsp ground cinnamon


  1. Heat oven to 350°F. Lightly grease a 9-inch square or round baking dish.
  2. In a large bowl, mash the bananas with a fork or potato masher.
  3. Stir in peanut butter, eggs and almondmilk. Mix well.
  4. Stir in oats, flaxseed and cinnamon until well combined. Pour mixture into prepared pan.
  5. Bake 25-30 minutes, or until center is set. Cool before cutting into squares.
  6. Store in an airtight container in the refrigerator up to 5 days.


  • Look for natural peanut butter (the kind with just peanuts and salt) to keep this recipe free of added sugar. 
  • You want really ripe bananas for this recipe. They’ll be easier to mash and give you the best flavor.
  • This recipe can easily be doubled in a 9x13 inch pan if you have a big family or want to freeze some for later.
  • This recipe also works with peanut butter powder. If you go with powdered peanut butter, use 1 cup powdered peanut butter and increase the almondmilk to 2 cups.
  • Make sure to use certified gluten-free oats if you or a family member has celiac or a gluten intolerance.
  • Feel free to add any extras, such as chopped peanuts or walnuts for crunch, or chocolate chips. Stir them in with the rest of the dry ingredients.
