Equipment

Ingredients

  • 2 Tablespoons of ground flaxseeds
  • 5 Tablespoons of water
  • 2 ripe bananas peeled
  • ¾ cup of peanut butter
  • ¼ cup of vegetable or canola oil
  • ½ cup of plant-based milk (any variety)
  • 1 teaspoon of vanilla extract
  • 2 cups of all-purpose flour
  • ½ cup of brown sugar
  • 1 ½ teaspoons of baking powder
  • ½ teaspoon of salt
  • ¾ cup to 1 cup of fruit preserves
  • Melted peanut butter for drizzling on top optional

Instructions

  • Preheat the oven to 350 degrees F and lightly grease a 9x13 baking pan or dish.
  • In a small bowl, beat together the flaxseed meal and water for 1 minute. Place in the refrigerator for 10 minutes.
  • Using a fork or potato masher, mash the bananas and stir in the peanut butter, oil, plant milk, vanilla, flour, sugar, baking powder, salt, and flaxseed mixture until it’s well-combined.
  • Pour the batter into the prepared baking pan, use the fruit preserves to create a layer of swirls on top of the batter, and bake for 50 minutes. Test by sticking a toothpick in the middle of the loaf. If the toothpick comes out dry, the loaf is done. If it’s not, bake in 5-minute increments until the toothpick comes out dry.
  • Drizzle melted peanut butter on top, optional.

Notes

  • Don’t overmix the batter: If you overwork the gluten flour, the vegan blondies may sink in the middle. 
  • Adjust the sweetness: You could experiment with reducing the amount slightly. I don’t recommend removing too much, as it also keeps the blondies soft/moist. 
  • Adjust the baking time: If you prefer your vegan blondies to be cakier or gooier, adjust the baking time.
