🍪 Butterscotch Oatmeal Pumpkin Bars: The Ultimate Fall Treat

(Author: Jason Griffith)

When the leaves start turning and the air gets that crisp, comforting chill, only one scent truly captures the season for me: pumpkin and spice. Forget the fancy pies—this year, I’m leaning into the pure, unadulterated comfort of these Butterscotch Oatmeal Pumpkin Bars. They take everything you love about an oatmeal cookie, a pumpkin spice latte, and a decadent bar dessert, and combine them into one incredibly easy, chewy, and deeply flavorful square.

These bars are my secret weapon for fall gatherings. They manage to be both hearty and tender, packed with that unmistakable blend of cinnamon, nutmeg, and ginger, but lifted by the unexpected sweetness of melted butterscotch chips. Best of all? They’re made in a 9×13 pan, meaning you get a generous batch perfect for sharing at a potluck or simply keeping your cookie jar stocked for cozy nights in.

Why I Love This Recipe

I’ve baked a lot of fall treats, from my favorite Easy Pumpkin Spice Muffins to classic pumpkin breads, but these bars stand out for a few key reasons:

• Texture Perfection: Thanks to the combination of melted butter, brown sugar, and old-fashioned oats, these bars are incredibly chewy without being dense.
• Speed and Simplicity: They mix up quickly in one bowl and bake in a single pan. No need for rolling out dough or individual cookies!
• The Butterscotch Factor: The butterscotch chips melt slightly during baking, creating gooey pockets of caramel-like flavor that complement the warm spices of the pumpkin perfectly. It’s an upgrade from the typical chocolate chip bar.
• Make-Ahead Magic: These bars actually improve overnight, making them an ideal dessert to prepare 24 hours before a party.

🥣 Ingredients You’ll Need

This recipe uses simple pantry staples, especially if you keep a good stash of fall baking spices on hand.

For the Bars
Unsalted Butter, melted	1/2 cup (1 stick)	Using melted butter helps achieve that chewy texture.

Swaps and Notes

• Oats: You must use old-fashioned (rolled) oats for the best texture. Quick oats will absorb too much moisture and make the bars dense.
• Spices: If you don’t have individual spices, you can substitute the cinnamon, nutmeg, and ginger with 1 3/4teaspoons of pre-mixed pumpkin pie spice.
• Chips: No butterscotch chips? Feel free to swap them for white chocolate chips, dark chocolate chips (like I use in my Chocolate Chip Banana Bread), or even chopped pecans.
• Make it Dairy-Free: Use a plant-based butter alternative and dairy-free butterscotch chips (or another dairy-free chip variety).

👩‍🍳 Step-by-Step Instructions

1. Preheat and Prep

Preheat your oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan, or line it with parchment paper, leaving an overhang on the long sides for easy lifting.

2. Wet Ingredients

In a large bowl, whisk together the melted butter, brown sugar, and granulated sugar until smooth. Add the pumpkin purée, eggs, and vanilla extract, and mix until everything is thoroughly combined.

3. Dry Ingredients

In a separate medium bowl, whisk together the flour, baking powder, baking soda, cinnamon, nutmeg, ginger, and salt. Whisking ensures the leavening and spices are evenly distributed.

4. Combine and Fold

Gradually add the dry ingredients to the wet ingredients, mixing only until just combined. Overmixing will develop the gluten and make your bars tough. Finally, gently stir in the oats and butterscotch chips.

5. Bake

Spread the batter evenly into your prepared baking pan. Bake for 25-30 minutes, or until the edges are set and a toothpick inserted into the center comes out clean or with just a few moist crumbs attached.

6. Cool

Let the bars cool completely in the pan on a wire rack before cutting into squares. Cooling is crucial for the bars to set and for the best texture.

7. Glaze (Optional)

If using the glaze, whisk together the powdered sugar, milk, and vanilla extract in a small bowl until smooth. Drizzle it decoratively over the cooled bars right before serving.

💡 Tips for Success

• Measure Flour Correctly: I always recommend the spoon and level method. Lightly spoon the flour into your measuring cup, then level off the top with a straight edge. Scooping directly from the bag can pack in too much flour, resulting in dry bars.
• Use Room Temperature Eggs: This helps them incorporate smoothly into the batter without seizing the melted butter.
• Parchment Paper is Your Friend: Lining the pan with parchment paper that hangs over the sides makes removing and cutting the bars incredibly easy and tidy.
• Don’t Overbake: The center of the bars should look slightly soft when you pull them out. They will continue to set as they cool. Overbaking is the quickest way to dry out any bar or brownie recipe (even The Best Peanut Butter Brownies).

Serving Suggestions and Pairings

These bars are substantial enough to be a standalone dessert, but they shine when paired with the right company:

• Coffee & Tea: A hot cup of black coffee or a spiced chai latte.
• Ice Cream: A scoop of vanilla bean ice cream or cinnamon ice cream on top turns this into an à la mode experience.
• Cocktails: For the adults, a cozy, sweet sipper like The Slippery Drank is the perfect match.

Storage and Leftover Tips

• Storage at Room Temp: Store the cooled, cut bars in an airtight container at room temperature for up to 4 days. If they are glazed, separate layers with parchment paper.
• Refrigeration: You can extend their life by refrigerating them for up to 1 week. Bring them back to room temperature before serving for the best texture.
• Freezing: These bars freeze beautifully! Once cooled and cut, wrap individual bars tightly in plastic wrap, then place them in a freezer-safe zip-top bag or container. They can be frozen for up to 3 months. Thaw overnight in the refrigerator or on the counter.
