1/2 cup creamy peanut butter
1 small, very ripe banana, mashed (about 1/3 cup)
1/3 cup maple syrup
2 1/2 cups quinoa flakes
1/4 cup milk
1/8 teaspoon kosher salt
1/2 cup chopped dark chocolate
Line a baking sheet with wax or parchment paper.
Place the peanut butter, banana, and maple syrup in a medium saucepan over low heat and stir until melted together and well-combined, 1 to 2 minutes.
Remove from the heat and stir in the quinoa flakes, milk, and salt. Cool the mixture until no longer warm, about 10 minutes.
Stir in the chocolate. Scoop the mixture by the tablespoon onto the prepared baking sheet. Use your hands to shape and flatten each scoop into a roughly 1/2-inch-thick round disc. Chill in the refrigerator until firm, at least 1 hour.
