Directions: No-Bake Oatmeal-Peanut Butter Chocolate Chip Bars

Step 1: Prepare the Pan
Start by greasing a 9×13 inch baking dish with a little butter or lining it with parchment paper for easy removal later.
Step 2: Melt the Butter and Sugar
In a microwave-safe bowl, combine the unsalted butter and granulated sugar. Microwave in 30-second intervals, stirring in between, until the mixture is completely melted and smooth.
Step 3: Mix in the Peanut Butter and Milk
Once the butter and sugar mixture is melted, stir in the creamy peanut butter and milk. Mix until well combined and smooth.
Step 4: Add Vanilla and Salt
Next, add the vanilla extract and salt to the mixture. Stir until everything is well incorporated.
Step 5: Combine with Oats and Chocolate Chips
In a large mixing bowl, combine the old-fashioned oats with 1 cup of the semisweet chocolate chips. Pour the peanut butter mixture over the oats and chocolate chips, stirring until everything is well coated.
Step 6: Transfer to the Baking Dish
Pour the mixture into the prepared baking dish and press it down firmly with a spatula to create an even layer.
Step 7: Add Remaining Chocolate Chips
Sprinkle the remaining 1 cup of chocolate chips on top of the pressed mixture, gently pressing them in so they stick.
Step 8: Refrigerate
Cover the dish with plastic wrap and refrigerate for at least 2 hours, or until the bars are firm.
Step 9: Cut into Squares
Once set, remove the bars from the refrigerator. Lift them out of the dish using the parchment paper (if used), and cut into squares or rectangles.
Smart Substitutions

If you don’t have all the ingredients on hand or are looking to customize your bars, consider these substitutions:
- Nut Butters: Swap peanut butter for almond butter or sunflower seed butter for a different flavor.
- Sweeteners: Use honey or maple syrup instead of granulated sugar for a natural sweetener.
- Oats: Quick oats can be used in a pinch, though the texture will be slightly different.
- Dairy-Free Options: Use coconut milk or almond milk instead of regular milk.
Insider Tips
- For a richer chocolate flavor, you can use dark chocolate chips instead of semisweet.
- Let the bars chill overnight for the best texture.
- For added crunch, mix in some chopped nuts or seeds.
- Be sure to press the mixture down firmly in the baking dish for a denser bar.
How to Store & Reheat
These No-Bake Oatmeal-Peanut Butter Chocolate Chip Bars can be stored in an airtight container in the refrigerator for up to a week. If you’d like to keep them longer, they also freeze well for up to three months. Just cut them into squares, wrap them individually in plastic wrap, and place them in a freezer-safe bag. When you’re ready to enjoy, simply let them thaw in the refrigerator or at room temperature.
Handy Q&A
Can I use quick oats instead of old-fashioned oats?
Yes, you can use quick oats, but the texture of the bars will be slightly different. Old-fashioned oats provide a chewier bite.
How do I make these bars gluten-free?
To make these bars gluten-free, ensure you use certified gluten-free oats and check that your chocolate chips are also gluten-free.
Can I add other mix-ins?
Absolutely! Feel free to add dried fruits, shredded coconut, or chopped nuts for added flavor and texture.
How can I make these bars healthier?
To make these bars healthier, consider reducing the sugar amount, using natural sweeteners like honey, and adding seeds or additional oats for more fiber.
