Ingredients:
- 1 cup All-Purpose Flour ((1 cup flour = 125 grams))
- 1/4 teaspoon Baking Powder
- 1/4 teaspoon Ground Cinnamon
- 1/4 teaspoon Kosher Salt
- 8 Tablespoons Unsalted Butter, melted and cooled slightly ((1 stick))
- 1 cup lightly packed Brown Sugar ((light or dark will work) (1 cup sugar = 200 grams))
- 1 large Egg
- 1 teaspoon Pure Vanilla Extract
- 1 cup Old Fashioned / Rolled Oats
- 1 cup Semi-Sweet Chocolate Chips ((see note))
- 1/2 cup M&Ms ((see note))
Cooking Instructions:
Step 1: Prepare Your Baking Vessel and Dry Ingredients
Before we even think about mixing, let’s get our baking pan ready. I like to use an 8×8 inch square baking pan for these bars. Line it with parchment paper, leaving some overhang on the sides. This makes it super easy to lift the entire block of baked bars out of the pan once they’ve cooled, and it also ensures a super clean release with no sticking. Once your pan is prepped, it’s time to get our dry ingredients organized. In a medium-sized bowl, whisk together the all-purpose flour, baking powder, ground cinnamon, and kosher salt. Whisking these together thoroughly ensures that the leavening agents and salt are evenly distributed throughout the batter, which is crucial for a consistent bake and great flavor. Don’t skip this step – it’s a small effort that makes a big difference!
Step 2: Cream the Wet Ingredients for a Tender Base
Now, let’s move on to the heart of our cookie bar base. In a larger bowl, combine the melted and slightly cooled unsalted butter with the lightly packed brown sugar. Using brown sugar is key here; its molasses content contributes to that wonderful chewy texture and rich, caramel-like flavor that makes these bars so irresistible. Cream these together with a whisk or a rubber spatula until they are well combined and look somewhat like wet sand. Next, crack in your large egg and add the pure vanilla extract. Whisk this mixture vigorously until it’s smooth and slightly fluffy. The vanilla extract will add a beautiful depth of flavor that complements the oats and chocolate perfectly.
Step 3: Combine Wet and Dry Ingredients and Incorporate the Stars
It’s time to bring our dry and wet ingredients together. Gradually add the dry flour mixture to the wet butter and sugar mixture. Stir gently with your rubber spatula or a wooden spoon until just combined. It’s really important here not to overmix the batter. Overmixing can develop the gluten in the flour too much, leading to tougher bars. We’re looking for a cohesive dough that’s starting to come together. Once the flour is mostly incorporated, it’s time to fold in the absolute stars of the show: the old-fashioned rolled oats, the semi-sweet chocolate chips, and the M&Ms. Gently fold them in until they are evenly distributed throughout the dough. Make sure to get all those delicious pockets of chocolate and chewy oats!
Step 4: Press the Dough into the Pan and Bake to Golden Perfection
Now, take your prepared 8×8 inch baking pan. Spoon the glorious dough into the pan. Because this dough is a bit sticky and thick, I find the easiest way to get an even layer is to use the back of my spatula or even lightly dampened hands to press the dough evenly into the bottom of the pan. Don’t worry if it’s not perfectly smooth; a slightly rustic look is part of its charm! Once evenly pressed, it’s time to bake. Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). Bake for 20 to 25 minutes, or until the edges are golden brown and the center looks set but still slightly soft. Keep an eye on them as oven temperatures can vary. You don’t want to overbake these, or they will lose their lovely chewy texture.
Step 5: Cool and Cut for Ultimate Enjoyment
This is perhaps the hardest part of making these bars: waiting! Once they come out of the oven, resist the urge to cut into them immediately. Let them cool in the pan on a wire rack for at least 15-20 minutes. This crucial cooling period allows the bars to firm up and become easier to handle. If you try to cut them while they’re too hot, they’ll likely fall apart. After they’ve cooled slightly in the pan, use the parchment paper overhang to carefully lift the entire block of baked goodness out of the pan and onto the wire rack to cool completely. Once fully cooled, use a sharp knife to cut them into your desired bar size. These bars are incredibly satisfying on their own, but they are also divine served with a glass of milk or a dollop of ice cream. Enjoy every single chewy, chocolaty bite!

Conclusion:
There you have it! These Oatmeal Chocolate Chip Bars are an absolute winner in my kitchen, and I’m confident they will be in yours too. The combination of chewy oats, melty chocolate chips, and just the right amount of sweetness makes them incredibly satisfying and perfect for any occasion. They strike that wonderful balance between wholesome and decadent, making them a fantastic choice for breakfast on the go, a satisfying afternoon snack, or even a simple dessert. I love how versatile they are, and the ease of preparation means you can whip them up without a fuss.
Enjoy these bars warm for an extra gooey chocolate experience, or let them cool completely for a firmer, more portable treat. They are also delightful crumbled over yogurt or ice cream! Don’t hesitate to get creative with variations – perhaps add some chopped nuts for extra crunch, a sprinkle of sea salt on top for a sweet and salty contrast, or even a dash of cinnamon for warmth. I truly encourage you to give these Oatmeal Chocolate Chip Bars a try. They are a guaranteed crowd-pleaser and a recipe you’ll return to again and again.
Frequently Asked Questions:
How do I store Oatmeal Chocolate Chip Bars?
You can store these bars in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week. For longer storage, I recommend wrapping them individually and freezing them for up to 3 months. They thaw beautifully at room temperature!
Can I make these bars gluten-free?
Absolutely! To make these Oatmeal Chocolate Chip Bars gluten-free, simply ensure you are using certified gluten-free rolled oats. All other ingredients are typically gluten-free, but it’s always a good idea to double-check labels if you have a severe gluten intolerance.
What kind of chocolate chips work best?
I find that semi-sweet chocolate chips offer the perfect balance of sweetness and chocolate flavor, but feel free to experiment! Milk chocolate chips will make them sweeter, while dark chocolate chips will provide a more intense chocolate taste. Mini chocolate chips also distribute well throughout the bars.
