Ingredients
Base Layer
- 1 cup (226 g) unsalted butter melted
- 2 cups (400 g) light brown sugar packed
- 1 cup (240 ml) light corn syrup
- 2 tsp (10 ml) vanilla extract
- 4 cups (360 g) quick-cooking oats not old-fashioned or steel-cut
Chocolate Peanut Butter Topping
- 1 1/2 cups (260 g) semisweet chocolate chips
- 1 1/2 cups (375 g) creamy peanut butter shelf-stable, not natural
Equipment
- 9x13-inch Baking Pan
- Saucepan
- Microwave-safe bowl
- Spatula
- Offset spatula or butter knife
- Parchment paper (optional)
Instructions
- Grease a 9x13-inch pan or line it with parchment paper. Preheat oven to 350°F (175°C).
- In a large saucepan, melt the butter over medium heat. Stir in brown sugar, corn syrup, and vanilla extract. Heat until the mixture is thick and bubbling slightly at the edges, then remove from heat.
- Add oats to the saucepan and stir until fully combined. The mixture will be thick and sticky.
- Spread the oat mixture evenly in your prepared pan. Press down firmly with a spatula or the back of a spoon to create a uniform base layer.
- Bake for 15 minutes. The bars will be slightly golden but won't darken much. Remove from oven and set aside.
- To make the topping, combine chocolate chips and peanut butter in a microwave-safe bowl. Melt in 30-second intervals, stirring between each, until smooth and glossy. (Alternatively, use a saucepan over low heat.)
- Pour the chocolate-peanut butter mixture over the warm oat base. Spread evenly with an offset spatula or knife.
- Let the pan cool at room temperature until the topping begins to set, then refrigerate for at least 1 hour, or until the bars are fully chilled and the topping is firm.
- Slice into squares (or any shapes you wish) and enjoy! Store bars in the fridge for a chewy, crisp bite.
Notes
For best results, use shelf-stable creamy peanut butter—not the natural, runny kind.
These bars freeze beautifully (separate layers with parchment; freeze up to 2 months).
If desired, substitute honey for corn syrup for extra flavor (bars will be slightly softer).
Quick oats are key for the texture—avoid old-fashioned or steel-cut.
For gluten-free bars, use certified gluten-free oats and chocolate chips.
