Ingredients You’ll Need

These ingredients work really well together to create that chewy, soft texture with just a touch of wholesome goodness. A mix of oats and whole wheat flours gives you fiber and a natural hearty flavor, while the melted coconut oil keeps things moist without being greasy.

• Old fashioned oats: These add chewiness and help bind the bars while keeping them hearty and wholesome.
• All-purpose flour: Provides structure but you won’t want to swap it all for whole wheat to keep these from getting too dense.
• White whole wheat or whole wheat pastry flour: Adds fiber and a slightly nutty flavor, a great healthier flour option.
• Light brown sugar: Adds natural molasses flavor and moisture; I usually stick to the lower sugar amount to keep it healthier.
• Granulated sugar: For a bit of extra sweetness and to balance the richness of the chocolate.
• Baking soda: Helps the bars rise just enough for great texture without puffing up too much.
• Kosher salt: Balances the sweetness and enhances all the flavors.
• Melted coconut oil: I love coconut oil here because it keeps the bars moist and adds a subtle flavor that blends beautifully with the oats.
• Eggs: Bind everything together; be sure to use large eggs for the right consistency.
• Vanilla extract: Elevates the whole flavor profile with warmth and sweetness.
• Dark chocolate chunks: My favorite part! Use a quality dark chocolate for richness and the perfect gooey pockets throughout.

Variations

I love tweaking this Healthier Dark Chocolate Chunk Oatmeal Cookie Bars Recipe to suit different moods or what I have on hand. Don’t hesitate to make it your own – that’s part of the fun!

• Add nuts: I’ve tossed in chopped walnuts or pecans to add crunch and boost healthy fats—my family goes crazy for that extra texture.
• Swap the chocolate: Use semi-sweet or bittersweet chocolate chunks depending on your sweetness preference, or even try adding dried cherries or cranberries for a fruity twist.
• Gluten-free: You can substitute the flours with a gluten-free blend and use certified gluten-free oats, which works well if you’re gluten-sensitive.
• Make it vegan: Replace eggs with flax eggs and use a vegan dark chocolate to keep it plant-based and still delicious.

How to Make Healthier Dark Chocolate Chunk Oatmeal Cookie Bars Recipe

Step 1: Prep Your Ingredients and Pan

Start by preheating your oven to 350°F (175°C). Grease a 9×13 inch baking dish with butter or line it with parchment paper. Lining it makes cleanup super simple and helps these bars slide out easily, especially since the dough is a bit crumbly.

Step 2: Mix All the Dry and Wet Ingredients

In a large mixing bowl or a stand mixer bowl, combine the oats, all-purpose flour, whole wheat flour, brown sugar, granulated sugar, baking soda, and salt. Then add the melted coconut oil, eggs, and vanilla extract. Mix everything together until the dough is just combined. It will look crumbly but hold together when pressed—that’s exactly what you want. If it feels too dry, a tiny splash of almond milk or water can help, but usually, the coconut oil and eggs do their job.

Step 3: Fold in the Dark Chocolate Chunks

Gently fold in the dark chocolate chunks so they’re evenly distributed throughout the dough. This part is my favorite because you get those pockets of rich chocolate in every bite.

Step 4: Press and Bake

Press the dough evenly into the prepared baking dish. Remember, it will seem crumbly but just keep pressing firmly to create an even layer. Bake for 18–20 minutes, or until the edges are set and the top is lightly golden—you can gently shake the pan to check for firmness. Avoid overbaking so they don’t dry out. A sprinkle of flaky sea salt on top before baking adds a beautiful savory contrast and makes the chocolate pop.

Step 5: Cool and Cut into Bars

Let the bars cool completely before slicing into squares. Cooling helps them firm up, so your bars hold together without falling apart. I usually cool them in the pan for about 30 minutes, then lift them out with the parchment paper and finish cooling on a rack.

How to Serve Healthier Dark Chocolate Chunk Oatmeal Cookie Bars Recipe

Garnishes

I love sprinkling a little flaky sea salt on top right after baking—it really amps up the chocolate flavor and adds a lovely contrast. Sometimes, I’ll dust them lightly with cinnamon for an extra cozy note or add a drizzle of melted dark chocolate for a fancy finish on special occasions.

Side Dishes

These cookie bars pair beautifully with a cup of coffee or herbal tea for afternoon snacks. You can also serve them alongside a bowl of fresh fruit or yogurt to keep things balanced and fresh-tasting.

Creative Ways to Present

When I’ve taken these bars to parties, I like to cut them into bite-sized squares and arrange them on a pretty platter with scattered chocolate chunks and whole oats for rustic charm. Wrapping individual bars in parchment paper and tying them with twine makes a lovely homemade gift too!

Make Ahead and Storage

Storing Leftovers

I store these bars in an airtight container at room temperature for up to 4 days, and they stay just as chewy and delicious. If your kitchen is warm, keeping them in the fridge also works well and preserves their texture.

Freezing

These bars freeze beautifully! I usually wrap individual bars tightly in plastic wrap, then place them in a freezer-safe bag. They keep well for up to 3 months, and I love having a stash of homemade treats on hand.

Reheating

To enjoy frozen bars, I let them thaw at room temperature or zap them in the microwave for 20-30 seconds to get that fresh-baked warm gooeyness back. You can also pop them in a toaster oven for a minute or two if you want a slight crisp on the edges.
