No Bake Peanut Butter Oatmeal Bars have a crunchy, buttery brown sugar oatmeal top and bottom with a fudgy peanut butter filling. They’re easy to make and whip up in just 20 minutes!
Line a 9 by 5-inch loaf pan with 2 pieces of parchment paper so it hangs over all 4 sides.
Add the butter, brown sugar, and salt to a medium saucepan over medium heat. Cook until the butter is melted, stirring occasionally. Stir in the oats and vanilla and cook until the oats are toasted, about 2 to 3 minutes, stirring occasionally.
Add half of the oat mixture to the prepared loaf pan. Spread it out evenly, and then press it down with a metal spatula.
Melt the white chocolate chips and peanut butter together in a medium bowl in the microwave or double boiler. Stir to combine.
Pour the white chocolate/peanut butter mixture on top of the oat mixture in the loaf pan. Spread it out evenly.
Sprinkle the remaining oat mixture on top.
Refrigerate until set, about 2 hours.
Cut into bars, and then drizzle the melted semi-sweet chocolate on top. Sprinkle on the flaky sea salt.
Serve.
Notes
Recipe Yield and Serving Size: This recipe makes 1 (9 by 5-inch) loaf pan, which is 8 servings.
Storage: Store leftovers in an airtight container in the fridge for up to 5 days.
Serving Tip: These bars have a more solid consistency straight from the fridge. If you let them sit at room temperature for 15 minutes, they have a fudgy consistency. Don’t leave them outside in the heat because they will melt.
For a Chocolate Filling Instead: Melt together 1 cup of semi-sweet chocolate chips + ½ cup of heavy whipping cream.
