How to Make Oatmeal Chocolate Chip Bars Recipe

Step 1: Preheat and Prepare Your Pan

Start by preheating your oven to 350 degrees Fahrenheit. This ensures it’s the ideal temperature to bake the bars evenly. Meanwhile, grease a 9×13-inch baking pan or line it with parchment paper to make sure your bars come out effortlessly once baked.

Step 2: Mix the Dry Ingredients

In a medium mixing bowl, combine the oats, flour, light brown sugar, granulated sugar, baking soda, salt, and ground cinnamon. Whisk these together until evenly blended; this mixture forms the heart of the bars’ texture and foundational flavor.

Step 3: Add the Wet Ingredients

Pour in the melted butter, followed by the eggs and vanilla extract. Mix all the ingredients together thoroughly until the dough is uniformly combined. It will be thick and a little sticky, which is exactly what you want for these bars.

Step 4: Fold in the Chocolate Chips

Gently fold the semi-sweet chocolate chips into the batter. This is the moment the recipe truly begins to shine, as those chocolate pockets distribute evenly throughout the oat mixture, promising gooey bites in every square.

Step 5: Bake to Perfection

Transfer the dough into your prepared pan and spread it into an even layer. Bake the bars for about 18 to 20 minutes, or until they turn a lovely light golden color and feel set in the middle. Avoid overbaking to keep that coveted chewy softness.

Step 6: Add the Finishing Touch

As soon as the bars come out of the oven, sprinkle the top with coarse sea salt. This little detail might seem small, but it brings out the chocolate’s sweetness and gives the bars a grown-up twist. Allow the bars to cool completely in the pan before slicing them into squares, so they hold their shape perfectly.

Garnishes

A light dusting of powdered sugar or an extra sprinkle of sea salt makes these bars visually irresistible and adds a subtle contrast to their sweet chewiness. Fresh berries on the side can also bring a refreshing pop of color and flavor.

Side Dishes

Serve these bars with a cold glass of milk, a scoop of vanilla ice cream, or even a cup of coffee or tea. Their hearty texture pairs beautifully with creamy or warm beverages, elevating snack or dessert time to a whole new level.

Creative Ways to Present

Cut them into fun shapes using cookie cutters for parties or pack them as treats in lunchboxes layered with parchment paper. For a fancier touch, drizzle melted chocolate or caramel over the bars, turning this humble recipe into a showstopper.

Make Ahead and Storage

Storing Leftovers

Once cooled, store your oatmeal chocolate chip bars in an airtight container at room temperature. They keep wonderfully for up to 4 days, maintaining their chewy texture and fresh flavors with no extra effort.

Freezing

If you want to make these ahead or save extras, freeze the bars in a single layer wrapped tightly in plastic wrap and stored inside a freezer-safe bag or container. They freeze beautifully for up to 2 months without losing any of their charm.

Reheating

Thaw frozen bars overnight at room temperature or warm them gently in the microwave for about 20 seconds. The chocolate chips will soften again, giving you that fresh-baked feel whenever the craving hits.

FAQs

Can I use quick oats instead of old-fashioned oats?

While old-fashioned oats lend the perfect chewiness in this recipe, you can substitute with quick oats in a pinch. The texture will be a bit softer and less hearty, but still delicious.

What type of chocolate chips works best?

Semi-sweet chocolate chips offer the ideal balance of sweetness and richness, but you can experiment with dark, milk, or even white chocolate chips depending on your preference.

Can I make these bars gluten-free?

Absolutely! Use a gluten-free all-purpose flour blend and ensure your oats are certified gluten-free, and this Oatmeal Chocolate Chip Bars Recipe will still come out perfect.

Is it possible to reduce the sugar?

You can slightly reduce the granulated and brown sugar amounts, though the texture might change a bit since sugar contributes to moisture and chew.

How do I know when the bars are done?

Look for a light golden color on top and edges that are just set. The center should no longer look wet, but a slight softness is what keeps them chewy.
