Chewy, chocolatey peanut butter granola bars made with hearty oats, crispy rice cereal, and a luscious honey–peanut butter binder. Perfect for make-ahead snacks, school lunches, or a sweet treat on the go.
Line an 8x8 inch baking pan with parchment paper, leaving overhang for easy lifting. Lightly grease the parchment.
In a large bowl, combine oats, crispy rice cereal, chopped peanuts, and 0.33 cup of the mini chocolate chips. Toss to distribute.
In a small saucepan over low heat, add peanut butter, honey, brown sugar, coconut oil, and fine sea salt. Warm, stirring constantly, until smooth and the sugar is dissolved, about 2 to 3 minutes. Remove from heat and stir in vanilla.
Immediately pour the warm peanut butter mixture over the dry ingredients. Mix with a spatula until every bit is evenly coated and sticky.
Transfer mixture to the prepared pan. Press very firmly into an even layer using a greased spatula or the bottom of a measuring cup to compact the bars.
Sprinkle the remaining mini chocolate chips over the top and press lightly so they adhere. Add flaky sea salt if using.
Refrigerate until set, about 15 to 20 minutes.
Lift out using the parchment overhang and cut into 16 bars. Store bars in an airtight container at room temperature for 3 days or refrigerate up to 1 week.
Notes
For cleaner slices, chill a bit longer before cutting and wipe the knife between cuts. Swap peanut butter with almond or sunflower seed butter as desired; thickness and sweetness may vary, so adjust honey slightly if needed.
