How to Make Oatmeal Cookie S’mores Bars
Step 1: Prepare Your Ingredients
Gather all ingredients and preheat your oven to 350°F (175°C). Lightly grease or line a baking pan with parchment paper for easier cleanup and perfect bar removal.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together old-fashioned oats, flour, baking soda, and salt. This helps evenly distribute the leavening agents and salt throughout the mixture.
Step 3: Cream Butter and Sugar
In a separate large bowl, beat softened butter and brown sugar together until creamy and fluffy, about 2-3 minutes. This step ensures your bars have a tender and rich crumb.
Step 4: Add Vanilla and Combine
Mix vanilla extract into the creamed butter and sugar, then gradually incorporate the dry ingredients until fully combined and a sticky dough forms.
Step 5: Layer the Bars
Press half of the dough into the bottom of the prepared pan to form an even base. Sprinkle half of the chocolate chips and marshmallows over the layer, then top with the remaining dough, pressing gently to seal.
Step 6: Bake to Perfection
Bake in the preheated oven for 20-25 minutes until golden brown and marshmallows are lightly toasted. The result should be crispy edges with a chewy, gooey center.
Step 7: Cool and Slice
Allow the bars to cool completely in the pan before slicing into squares. This helps the bars to set and hold together beautifully.
Pro Tips for Making Oatmeal Cookie S’mores Bars
- Use Room Temperature Butter: Ensures smooth mixing and even texture in the dough.
- Don’t Overbake: Removing the bars just as the edges turn golden helps keep the center soft and gooey.
- Press Evenly: Firmly pressing dough layers prevents gaps in the bars and promotes great layering.
- Customize Chocolate: Experiment with mini chips or chunks for different melty textures.
- Cool Completely: Let bars cool fully before cutting to avoid crumbling.
How to Serve Oatmeal Cookie S’mores Bars

Make Ahead and Storage
Storing Leftovers
Keep leftover Oatmeal Cookie S’mores Bars in an airtight container at room temperature for up to three days to maintain freshness and chewiness.
Freezing
Wrap bars tightly in plastic wrap and place in a freezer-safe container for up to three months. Thaw at room temperature before serving for the best texture.
Reheating
Warm individual bars in the microwave for 15-20 seconds or in a low oven (300°F) for about 5-7 minutes to revive the gooey marshmallow and melty chocolate layers.
FAQs
Can I use quick oats instead of old-fashioned oats?
Old-fashioned oats work best because they hold their texture and chewiness; quick oats tend to create a softer, less satisfying bite, but you can substitute if needed.
Are these bars suitable for kids?
Absolutely! Oatmeal Cookie S’mores Bars are kid-friendly treats with familiar flavors and a fun, gooey texture that children love.
Can I make these bars nut-free?
Yes, this recipe doesn’t include nuts by default, but always check the chocolate and other ingredients for cross-contamination if allergies are a concern.
How long do these bars stay fresh?
Stored in an airtight container, they stay fresh for about three days at room temperature and up to a week in the fridge.
Can I double the recipe?
Yes, doubling works great — just use a larger baking pan or bake in two batches to ensure even cooking.
