Ingredients

Oatmeal Crust

  • 3/4 cup all-purpose flour
  • 3/4 cup rolled oats
  • 1/4 cup packed brown sugar
  • 1/8 teaspoon salt
  • 1/2 cup melted vegan butter

Peanut Butter Filling

  • 1 1/2 cups creamy peanut butter not the natural kind with oil separation

US Customary - Metric

Instructions

  • Preheat the oven to 350 degrees F and line a 8-inch square pan with parchment paper, leaving some overhang for easy removal later. Set aside.
  • In a medium-sized bowl, stir together the flour, rolled oats, brown sugar and salt. Add the melted butter and stir until the mixture resembles moist crumbs.
  • Press the crumbs into the prepared pan and press firmly and evenly. Bake for 11-13 minutes until the edges turn slightly golden brown. Remove from oven and let cool while you prepare the filling.
  • To the bowl of a stand mixer with the paddle attachment (or using an electric hand mixer), add the peanut butter and softened vegan butter. Mix until combined, or for about 1 minute. Add the powdered sugar and mix until combined, scraping the sides as needed.
  • Spread the peanut butter mixture evenly onto the crust and place in the refrigerator to chill while you prepare the chocolate topping.
  • In a microwave-safe bowl, melt the chocolate chips and oil in 30-second increments, stirring in between, until melted and smooth.
  • Spread the chocolate over the peanut butter layer, sprinkle with coarse salt (optional), and return to the refrigerator to chill for at least 30 minutes.
  • Cut into squares, serve and enjoy!

Notes

  1. Gluten-free: Substitute a quality gluten-free all-purpose flour and make sure to use gluten-free certified rolled oats.
  2. You may substitute almond or sunflower seed butter, if needed.
