Line an 8x8 or 9x9 square baking pan with parchment paper. Set aside.
In a medium saucepan set over low heat, combine 1 cup creamy peanut butter and ½ cup maple syrup. Stir until smooth.
Remove from the heat and stir in the 1 teaspoon vanilla extract and ¼ teaspoon salt.
Add the 4 cups rice crispy cereal and using a spatula fold the cereal in to evenly coat it.
Transfer the mixture to the prepared square baking pan.
Press the mixture firmly and evenly into the pan using the spatula. Set aside.
For the chocolate layer:
In a microwave safe bowl, add the 1 ½ cups semi sweet chocolate chips, ¼ cup creamy peanut butter and 1 tablespoon coconut oil.
Heat the chocolate in 20 second intervals, stirring between each interval, until chocolate is melted. Pour the chocolate mixture over the peanut butter crispy base and spread evenly with a spatula.
Warm the reserved 2 tablespoon creamy peanut butter in the microwave for 20 seconds. Then drizzle over the chocolate and use a toothpick or knife to create swirls. Top with ¼ teaspoon flaky sea salt, if desired.
Notes
Natural peanut butter with oil separation is not recommended unless it has been well mixed with a hand mixer and is no longer separated. Use your favorite chocolate chips, milk chocolate or semi sweet works well. You can also use chocolate chunks or a bar.Use solid coconut oil, not refined melted coconut oil because it solidifies again after cooling which helps hold the bars together.These bars hold best when chilled. Let them sit at room temperature for a few minutes before serving if you prefer a softer texture.
