Ingredients

For the Crunch Base & Topping:

2 cups (200g) crisp rice cereal (e.g., Rice Krispies)
1 ½ cups (180g) quick-cooking oats (certified gluten-free if needed)
½ cup (70g) roasted, salted peanuts, roughly chopped
⅓ cup (45g) hemp seeds or chia seeds (optional, for added nutrition)
1 pinch of fine sea salt

For the Chocolate-Peanut Butter Binding:

1 ¼ cups (210g) high-quality dark chocolate chips or chopped baking chocolate (60-70% cocoa)
⅔ cup (165g) smooth, natural peanut butter (well-stirred)
⅓ cup (80ml) pure maple syrup or agave nectar
1 teaspoon pure vanilla extract

Optional Add-ins & Toppings:

Flaky sea salt for sprinkling
2 tablespoons melted peanut butter for drizzling

Equipment Needed

8×8 inch (20×20 cm) square baking pan
Parchment paper
Large heatproof mixing bowl
Medium saucepan or heatproof bowl for double boiler
Spatula
Measuring cups and spoons

Step-by-Step Instructions

Step 1: Prepare the Pan

Line your 8×8 inch pan with a sheet of parchment paper, leaving some overhang on two opposite sides. This “sling” will make it incredibly easy to lift the entire set block out of the pan later for clean cutting. Lightly grease the exposed sides of the pan with a neutral oil or cooking spray.

Step 2: Mix the Dry Ingredients

In your large mixing bowl, combine the crisp rice cereal, quick oats, chopped peanuts, hemp/chia seeds (if using), and the pinch of salt. Stir with a spatula until everything is evenly distributed. Set aside.

Step 3: Create the Chocolate Binding

This is a one-pot process. Choose your method:

Saucepan Method: Combine the chocolate chips, peanut butter, and maple syrup in a medium saucepan. Place over low heat, stirring constantly with a spatula until the chocolate is completely melted and the mixture is smooth, glossy, and uniform. This should take 3-5 minutes. Do not let it boil.
Double Boiler Method: If worried about scorching, place the ingredients in a heatproof bowl set over a pot of simmering water (ensure the bowl doesn’t touch the water). Stir until melted and smooth.

Once melted, remove from heat immediately and stir in the vanilla extract.

Step 4: Combine & Press

Pour the warm, liquid chocolate mixture over the bowl of dry ingredients. Using your spatula, fold and stir until every single piece of cereal and oat is thoroughly coated in the chocolate-peanut butter magic.

Transfer the mixture to your prepared pan. Use the spatula, and then your fingers or the bottom of a flat glass (lightly greased), to press the mixture down firmly and evenly into an compact, uniform layer. This firm press is crucial for bars that hold together.

Step 5: Add Finishing Touches & Set

If desired, sprinkle the top with a few flakes of sea salt and drizzle with extra melted peanut butter. This not only looks professional but adds great flavor contrast.

Place the pan, uncovered, in the refrigerator. Allow the bars to chill and set completely for at least 1 hour. For a firmer, cleaner-cut bar, you can leave them for 2-3 hours or overnight.

Step 6: Slice & Serve

Using the parchment paper sling, carefully lift the entire block out of the pan and onto a cutting board. With a sharp knife, slice into 12 rectangular bars (or 16 squares for smaller portions). For the cleanest cuts, wipe the knife with a hot, damp towel between slices.
