Ingredients:
For the Oat Layer:*
1 cup (2 sticks) unsalted butter
3¼ cups old-fashioned oats
½ cup brown sugar, packed
½ teaspoon ground cinnamon
2 teaspoons vanilla extract
For the Chocolate Layer:*
1 bag (about 12 oz) dark chocolate chips
⅔ cup creamy peanut butter
Instructions:
Step 1: Prepare the Oat Mixture*
In a large saucepan over medium heat, combine the butter, brown sugar, and vanilla. Cook, stirring occasionally, until the butter and sugar are completely melted and smooth.
Step 2: Add the Oats*
Add the oats and cinnamon to the saucepan. Stir well to coat the oats with the butter mixture and cook for 2-3 minutes, until the oats are fragrant and slightly toasted.
Step 3: Layer the Oats*
Grease a 9×9-inch baking dish well with butter or non-stick spray. Press half of the oat mixture firmly into the bottom of the prepared dish, spreading it evenly.
Step 4: Melt the Chocolate*
In a microwave-safe bowl, combine the dark chocolate chips and peanut butter. Microwave in 30-second increments, stirring between each, until the chocolate is fully melted and the mixture is smooth.
Step 5: Assemble the Bars*
Spread most of the chocolate mixture over the oat layer in the baking dish, reserving a small amount for drizzling on top. Press the remaining oat mixture over the chocolate layer, then drizzle the reserved chocolate over the top.
Step 6: Chill and Slice*
Place the baking dish in the freezer for at least 1 hour to set. Once firm, slice into bars and serve.
Tips:
- Use Old-Fashioned Oats: They provide a chewy texture and hold up better than quick oats.
- Press Firmly: Pressing the oat layers firmly into the pan helps the bars hold together.
- Chill Thoroughly: The bars need at least an hour in the freezer to set properly.
- Customize the Chocolate: Use semi-sweet or milk chocolate chips if you prefer.
- Add a Crunch: Stir in chopped nuts or shredded coconut for extra texture.
Serving Suggestions:
- Serve with a glass of cold milk or a cup of coffee.
- Pack in lunchboxes for a sweet treat.
- Drizzle with extra melted chocolate or caramel before serving.
Storage Options:
- Refrigerator: Store in an airtight container in the refrigerator for up to 1 week.
- Freezer: These bars freeze well for up to 2 months. Store in a freezer-safe container and thaw before serving.
- Room Temperature: They can be kept at room temperature for a few hours, but refrigeration is recommended for longer storage.
No-Bake Chocolate Oat Bars are a simple, delicious, and satisfying treat that comes together in minutes with no oven required. Chewy, chocolatey, and packed with peanut butter flavor, they’re perfect for any occasion. Enjoy!
