No-Bake Peanut Butter Bars
Ingredients
Equipment
Method
- Begin by mixing the creamy peanut butter, honey, and vanilla extract in a medium bowl until the mixture is smooth and fragrant, about 2 minutes. It should be thick but easy to stir, with a slightly sticky feel.
- Add the graham cracker crumbs to the peanut butter mixture and fold everything together with a spatula until well combined. The mixture will become thick and crumbly but should hold together when pressed.
- Line your 8-inch square pan with parchment paper, leaving some overhang for easy removal. Using the spatula, press the mixture evenly into the prepared pan, smoothing the top for a flat surface. Press firmly to compact the mixture and create an even layer.
- Place the pan in the refrigerator for at least 2 hours, or until the mixture is firm and set. The bars will become chewy and fudgy as they chill.
- Once firm, melt the chocolate chips in a microwave-safe bowl in 20-second bursts, stirring between each, until smooth and glossy. This will take about 1 minute total. The melted chocolate should be silky and shiny, ready to be poured.
- Spread the melted chocolate evenly over the chilled peanut butter mixture using a spatula or the back of a spoon. Cover the entire surface with a smooth, glossy layer of chocolate.
- Return the pan to the fridge for another 30 minutes, or until the chocolate is set and shiny. The bars will be firm, with a beautiful glossy top and a chewy base.
- Using the overhang of parchment paper, lift the entire block of bars out of the pan and place on a cutting board. Slice into 12 even squares with a warm, sharp knife for clean, neat edges.
- Serve the bars immediately or store them in an airtight container in the fridge. They keep well for up to a week and are perfect for a quick, indulgent treat.
Tips & tricks for perfect no-bake bars
- Use room temperature peanut butter for easier mixing.
- Press the mixture firmly into the pan for even thickness.
- Melt chocolate gently to avoid burning or seizing.
- Chill in a flat, even layer to prevent cracks.
- Use a warm knife for clean slices.
Common mistakes and how to fix them
- FORGOT TO CHILL: Chill longer or in a colder environment to set properly.
- DUMPED TOO MUCH CHOCOLATE: Use a thinner layer or re-melt and re-spread.
- OVER-TORCHED CHOCOLATE: Use a lower heat setting or shorter melt time.
- STICKY MIXTURE: Add a few more graham crumbs or oats to dry it out slightly.
Quick fixes for common issues
- When mixture is too sticky, add more graham crumbs.
- Splash a bit of hot water on the knife for smoother cuts.
- Patch cracks by pressing the edges with a spoon.
- Shield chocolate with a thin layer of coconut oil if it’s dull.
- Rescue a crumbly base by pressing it back into the pan firmly.
Make-ahead tips for perfect bars
- Prepare the base mixture ahead of time; keep in an airtight container for up to 2 days.
- Chill the assembled bars for at least 2 hours, or overnight, to set fully.
- Chocolate topping can be added just before serving to keep it shiny.
- Store leftovers in the fridge for up to a week; cover tightly to prevent drying out.
