A little history behind your favorite no-bake snack
- These bars are inspired by classic American peanut butter treats from the 70s, simplified for modern kitchens.
- Corn syrup, a key ingredient, was historically used to help bind and sweeten candies and confections efficiently.
- Chocolate-covered peanut butter confections date back to the early 1900s, evolving into many forms, including these bars.
- The combination of peanut butter and chocolate is often referred to as a classic flavor duo, dating back to the famous Reese’s Peanut Butter Cups.
Ingredient insights and tweaks
- Peanut butter: I prefer natural, oily kinds for a richer, more authentic flavor. Swap with almond or cashew butter for variety.
- Chocolate: Use semi-sweet or dark for depth. Milk chocolate can be too sweet and thin when melted.
- Butter: Adds richness and helps the chocolate melt smoothly. Substitute with coconut oil for a dairy-free version.
- Graham cracker crumbs: They give structure and a slight sweetness. Crushed cookies or oats can work if you’re out.
- Powdered sugar: It binds everything nicely and adds sweetness. You can reduce or replace with honey or maple syrup, but it changes the texture.
Spotlight on Peanut Butter and Chocolate
Chocolate: Melts into a shiny, smooth layer that crackles when cooled. Use good quality for the best snap.:
- Natural peanut butter: It’s oozy and oily, creating a rich, authentic peanut flavor. Stir well before measuring.
- During melting, it turns glossy and smooth, making spreading easy and mess-free.
Coconut oil: Adds a glossy sheen and helps the chocolate layer set smoothly, with a subtle coconut scent.:
- Peanut butter: It has a slightly sticky texture that helps the layers adhere. Warm it slightly for easier mixing.
- Chocolate: When melted, it shimmers and has a deep, smoky aroma that signals it’s ready.
Ingredient swaps for different diets and flavors
- Dairy-Free: Use coconut oil instead of butter for a dairy-free chocolate layer, maintaining a shiny finish.
- Sweetener: Swap powdered sugar with honey or maple syrup for a softer, more complex sweetness.
- Crunchy Texture: Mix in chopped nuts or rice cereal for added crunch.
- Flavor Boost: Add a pinch of sea salt or vanilla extract to enhance flavor depth.
- Vegan Option: Use dairy-free chocolate and plant-based butter or coconut oil.

- Microwave or double boiler: Melting chocolate and butter evenly.
- Spatula or spoon: Spreading and smoothing layers.

- 1 cup natural peanut butter smooth or crunchy
- 1 cup powdered sugar sifted
- 1 1/2 cups graham cracker crumbs
- 1 cup semi-sweet chocolate chips
- 1 tablespoon coconut oil optional, for sheen
Instructions
- Line your 20cm (8-inch) pan with parchment paper, leaving overhang on the sides for easy removal.
- In a microwave-safe bowl, combine the melted butter and peanut butter. Microwave in 30-second bursts, stirring until smooth and glossy with a fragrant nutty aroma.

- Press the peanut butter mixture evenly into the prepared pan, using the back of a spatula or your fingers to smooth the top and create a firm, flat surface. You should hear a satisfying resistance as you press, and the layer will feel dense and sticky.
- In a separate bowl, melt the chocolate chips and coconut oil together using short bursts in the microwave, stirring well after each to achieve a shiny, smooth chocolate sauce with a rich aroma. This should take about 1 minute in total.
- Pour the melted chocolate over the peanut butter layer, spreading it evenly with a spatula or the back of a spoon. You want a smooth, glossy surface that crackles slightly as you spread, signaling a perfect coating.
- Place the pan in the fridge and chill for at least 2 hours, or until the chocolate is firm and the bars are set. For quicker results, freeze for about 1 hour.
- Once chilled and firm, lift the bars out of the pan using the parchment overhang. Use a sharp knife to cut into 12 even squares, pressing down firmly for clean edges.
- If desired, melt a little extra chocolate and drizzle over the tops of the bars for an extra decorative touch. Allow the drizzle to set slightly before serving.
