Why This Recipe Works

These Oatmeal Chocolate Chip Bars are not your average dessert. The combination of old-fashioned oats and semi-sweet chocolate chips creates a texture that is both chewy and satisfying. The use of brown sugar adds a deep, caramel-like flavor, while the granulated sugar helps achieve that perfect balance of sweetness. The addition of an egg and an extra yolk gives these bars a moisture that makes them irresistibly soft. The sprinkling of flaky sea salt on top elevates the flavor profile, making every bite a little more exciting. Simple ingredients combine to create a magical treat that everyone will love.

Oatmeal Chocolate Chip Bars — Do This Next

Step 1: Preheat Your Oven
Preheat your oven to 350°F (175°C). This ensures that your Oatmeal Chocolate Chip Bars bake evenly and come out with the perfect texture.
Step 2: Prepare the Baking Pan
Line a 9×13-inch baking pan with parchment paper, leaving some overhang on the sides. This will make it easier to lift the bars out once they’re baked.
Step 3: Cream the Butters and Sugars
In a large mixing bowl, combine the cut-up butter, packed brown sugar, and granulated sugar. Using a hand mixer or stand mixer, beat the mixture on medium speed until it is light and fluffy, about 2-3 minutes.
Step 4: Add the Eggs and Vanilla
Add the large egg, egg yolk, and vanilla extract to the butter-sugar mixture. Beat until well combined, scraping down the sides of the bowl as necessary.
Step 5: Combine the Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, baking powder, sea salt, and ground cinnamon. Slowly add this dry mixture to the wet ingredients, mixing just until combined.
Step 6: Fold in Oats and Chocolate Chips
Gently fold in the old-fashioned oats and semi-sweet chocolate chips using a spatula. Be careful not to overmix, as this can make the bars tough.
Step 7: Spread the Batter
Pour the batter into the prepared baking pan and spread it evenly. Use a spatula to smooth the top.
Step 8: Add the Finishing Touch
Sprinkle a pinch of flaky sea salt across the top of the batter. This will enhance the flavors and give a delightful contrast to the sweetness.
Step 9: Bake
Bake in the preheated oven for 25-30 minutes, or until the edges are lightly golden and a toothpick inserted in the center comes out with a few moist crumbs.
Step 10: Cool and Serve
Allow the bars to cool in the pan for about 10 minutes before lifting them out using the parchment paper overhang. Transfer to a wire rack to cool completely. Cut into squares and enjoy!
Flavor-Forward Alternatives

- Nutty Variations: Add 1/2 cup of chopped nuts like walnuts or pecans for a delightful crunch.
- Fruit Additions: Mix in 1/2 cup of dried fruits like cranberries or raisins for a chewy texture.
- Different Chocolate: Swap out semi-sweet chocolate chips for dark chocolate or white chocolate for a different flavor profile.
- Spice It Up: Experiment with spices by adding a pinch of nutmeg or ginger for a warm flavor kick.
Insider Tips
- Use high-quality chocolate chips for the best flavor in your Oatmeal Chocolate Chip Bars.
- Don’t skip the flaky sea salt—its contrast to the sweetness is what makes these bars truly special.
- For softer bars, slightly underbake them; they’ll continue to firm up as they cool.
- Let the bars cool completely before cutting for cleaner edges and squares.
Refrigerate, Freeze, Reheat
These Oatmeal Chocolate Chip Bars are perfect for meal prep! Store them in an airtight container at room temperature for up to a week. If you want to keep them longer, they freeze beautifully. Just wrap individual bars in plastic wrap and place them in a freezer-safe bag. They can be frozen for up to three months. When you’re ready to enjoy, simply remove a bar and let it thaw at room temperature or pop it in the microwave for a few seconds to warm it up.
Ask & Learn
Can I use quick oats instead of old-fashioned oats?
While you can use quick oats, be aware that the texture of the bars will be different. Old-fashioned oats provide a chewier texture that complements the chocolate nicely.
What can I do if my bars are too crumbly?
If your Oatmeal Chocolate Chip Bars turn out crumbly, it might be due to overbaking or not enough moisture. Next time, try reducing the baking time or adding a bit more butter or egg to the mixture.
Can I make these bars gluten-free?
Yes! Substitute the all-purpose flour with a 1:1 gluten-free flour blend, and ensure your oats are certified gluten-free.
How do I know when the bars are done baking?
The bars are done when the edges are lightly golden and a toothpick inserted into the center comes out with a few moist crumbs. They may look slightly underbaked in the center, but they will firm up as they cool.
