Ingredients
To make these incredible Butterscotch Oat Bars, you will need:

- 1 1/2 cups all-purpose flour: For structure. Feel free to substitute with a gluten-free blend if needed.
- 2 cups old-fashioned oats: Gives that chewy texture. Avoid quick oats as they won’t yield the same result.
- 1/2 teaspoon baking soda: Adds lift to your bars.
- 1/2 teaspoon baking powder: Works alongside the baking soda for a fluffy texture.
- 1/2 teaspoon kosher salt: Balances the sweetness.
- 1/2 cup unsalted butter, room temperature: I recommend using a high-quality butter like Kerrygold for extra creaminess.
- 1 cup light brown sugar, packed: This gives that deep butterscotch flavor.
- 2 large eggs, room temperature: Bring eggs to room temperature for better mixing.
- 1 tablespoon molasses: Adds a touch of depth; this ingredient is key!
- 1 teaspoon vanilla extract: Always use pure vanilla extract for the best flavor.
- 2 cups butterscotch chips, divided: The star of the show! I love using Guittard or Nestlé’s for a delicious melt.
- Butterscotch sauce for topping (optional): Drizzle over the bars for an indulgent finish.
Preparation note: Ensure your butter and eggs are at room temperature for easier blending and a smoother consistency.
Step-by-Step Instructions
1. Preheat
Preheat your oven to 350°F (175°C) and spray a 9×13-inch baking dish with baking spray, ensuring the bars won’t stick.
2. Mix Dry Ingredients
In a large mixing bowl, stir together the flour, oats, baking soda, baking powder, and salt. Set aside.
3. Cream Butter and Sugar
In the bowl of a stand mixer fitted with a paddle attachment, combine the room-temperature butter and brown sugar. Beat on low speed until smooth and creamy, usually about 2-3 minutes.
4. Add Eggs and Flavorings
Add the eggs, molasses, and vanilla extract to the mixing bowl, mixing until fully incorporated. You should see a beautiful golden mixture!
5. Combine Wet and Dry Ingredients
Slowly add the dry ingredients to the wet mixture. Mix gently until everything is just combined. Avoid overmixing to maintain a perfect texture!
6. Add Butterscotch Chips
Stir in 1 1/2 cups of butterscotch chips until evenly distributed throughout the batter.
7. Press and Sprinkle
Transfer the mixture into your prepared baking dish, pressing it evenly into the corners. Sprinkle the remaining 1/2 cup of butterscotch chips on top for that extra melty goodness!
8. Bake
Bake for 25-30 minutes, or until the edges are golden brown and a toothpick inserted comes out with a few moist crumbs. Keep an eye on it during the last few minutes!
9. Cool and Serve
Allow the bars to cool in the pan for about 15 minutes before drizzling with butterscotch sauce if desired. Cut into squares, serve, and enjoy!

Expert Tips & Tricks
Room Temperature Ingredients: This can’t be stressed enough—ensure that your butter and eggs are at room temperature for an even mix, contributing to that perfect texture.
Storage: Store your cooled Butterscotch Oat Bars in an airtight container at room temperature for up to 5 days. For longer storage, you can freeze them for up to 3 months.
Make-ahead Instructions: Feel free to prepare the dry ingredients a day in advance. Just combine and keep them in an airtight container until you’re ready to mix!
Troubleshoot Common Issues: If your bars turn out too dry, check your oven’s accuracy. And if they crumble when cutting, they might need more cooling time. Take a breath—you’ve got this!
Texture Tips: If you prefer chewier bars, bake for a bit less time. If you like crispy edges, add an extra minute or two to the baking time.
Elevate Your Bars: For an impressive presentation, cut them into signature shapes or drizzle additional butterscotch sauce over the top just before serving.

FAQ SECTION
Can I substitute the butterscotch chips?

Can I make these bars gluten-free?
- Yes, just use a gluten-free all-purpose flour blend with xanthan gum for best results.

- Bake for a shorter time. These bars should be set but soft in the center for a chewier texture.
Can I add fresh fruits?
- You can add fresh fruits like banana or apple slices, just be cautious of the added moisture, which could affect the texture.
What do I do if my bars are too crumbly?
- This can happen if there’s not enough moisture or if they were overbaked. If you bake them again, make sure to add a touch more butter or an extra egg.

Why are my bars not holding together?
- If they didn’t hold together, they might not have baked long enough, or you might want to ensure you’ve packed your brown sugar correctly.
Can I add spices for flavor?
- Yes! A teaspoon of cinnamon or a pinch of nutmeg can elevate the flavor profile beautifully.
How should I cut these bars?
