Ingredient Breakdown & Tips

• Peanut butter: I prefer creamy for smooth bars, but crunchy adds a nice texture.
• Honey or maple syrup: I use honey for its rich sweetness and stickiness, but agave works.
• Graham cracker crumbs: They give a subtle sweetness and crunch, but crushed biscuits are fine.
• Chocolate chips: Semi-sweet are my favorite, but dark or milk chocolate can change the flavor.
• Salt: A pinch enhances the overall taste, especially if using unsalted peanut butter.

Spotlight on Peanut Butter and Chocolate

Chocolate chips:

• Peanut butter: Rich, oozing, and slightly salty. It melts into the mixture, giving a creamy texture.
• It behaves during melting—smooths out quickly, so don’t overheat.
• Choose natural or processed—both work, but natural can add a peanut oil sheen.

Optional toppings or drizzles:

• Chocolate chips: Melty and shiny when warm, they set to a smooth, crackly surface.
• Use high-quality chips for better flavor and shine.
• Avoid over-microwaving to prevent burning or seizing.

Ingredient Substitutions

• Dairy-Free: Use coconut or almond butter instead of peanut butter, for a nutty flavor without dairy.
• Vegan: Swap honey for maple syrup or agave, and use dairy-free chocolate.
• Gluten-Free: Ensure graham crackers or biscuits are gluten-free, or use crushed rice cereal.
• Sweetener: Maple syrup or agave can replace honey for a different sweetness profile.
• Extra Crunch: Add chopped nuts or seeds on top before chilling.

Equipment & Tools

• 8-inch square pan: To hold and shape the bars
• Parchment paper: For easy removal and cleanup
• Microwave or double boiler: To melt chocolate and peanut butter
• Spatula or spoon: To spread and press the mixture

Step-by-Step Guide to No-Bake Peanut Butter Bars

1. Line an 8-inch square pan with parchment paper, leaving a bit overhang for easy lifting.
2. In a microwave-safe bowl, melt 1 cup of peanut butter with 1/2 cup of honey or maple syrup for 30 seconds. Stir until smooth.
3. Add 2 cups of graham cracker crumbs or crushed digestive biscuits to the peanut butter mixture. Mix well.
4. Press the mixture evenly into the prepared pan, smoothing the top with the back of a spoon. Chill for 30 minutes.
5. Meanwhile, melt 1 cup of chocolate chips in a bowl over a double boiler or microwave in short bursts, stirring often.
6. Pour the melted chocolate over the chilled peanut butter layer, spreading evenly. Chill for at least 1 hour, until firm.
7. Once set, lift the whole block out using the parchment overhang. Slice into squares with a sharp, warm knife.
8. Store in an airtight container in the fridge for up to a week. For softer bars, let sit at room temp for 10 minutes before eating.

Chill the bars in the fridge for at least 1 hour before slicing. Use a warm knife for clean cuts.
