• Unsalted Butter: Adds rich, buttery depth and creates a tender texture
• Brown Sugar: Infuses the bars with deep caramel notes and chewiness
• Large Eggs: Provide structure and lift while keeping the crumb moist
• Vanilla Extract: Enhances the overall sweetness and aroma
• All-Purpose Flour: Forms the backbone of the bars, holding everything together
• Baking Powder: Ensures a slight rise and prevents the bars from becoming too dense
• Salt: Balances the sweetness and sharpens flavors
• Butterscotch Chips: Create gooey, sweet pockets throughout the bars
• Toffee Bits: Add crunchy texture and a buttery burnt-sugar finish

Smart Substitutions to Customize Your Butterscotch Toffee Cookie Bars

If you’re missing an ingredient or catering to dietary needs, try these swaps:

• Flour Swap: Use a 1:1 gluten-free baking mix for a celiac-friendly version
• Toffee Substitute: Replace with chopped caramel candies or toasted pecans for crunch
• Chip Alternatives: Swap butterscotch chips with semi-sweet chocolate or white chocolate chips for variety
• Butter Options: Use plant-based butter for a dairy-free alternative, adjusting salt as needed

Prep the Pan: Preheat your oven to 350°F (177°C). Line a 9×13-inch baking pan with parchment paper, leaving an overhang to help lift the bars out after baking.
Mix Butter & Sugar: In a large bowl, whisk melted butter and packed brown sugar together until glossy and smooth, about 90 seconds. This step ensures a chewy texture.
Add Eggs & Vanilla: Add eggs one at a time, whisking well after each. Stir in vanilla extract until the mixture is thick and custardy.
Incorporate Dry Ingredients: Sift flour, baking powder, and salt directly into the wet mixture. Fold gently with a spatula until just combined. Don’t overmix.
Add Mix-Ins: Fold in butterscotch chips and toffee bits evenly throughout the batter.
Spread & Bake: Transfer the dough to your prepared pan, smoothing the top. Bake for 25–30 minutes until the edges are golden and the center is just set.
Cool & Cut: Let the bars cool in the pan for at least 90 minutes. Lift using parchment overhang, then slice into squares for clean edges.

Can I use salted butter instead of unsalted?

Yes, you can substitute salted butter, but reduce or omit the added salt in the recipe. This helps keep the flavor balanced and prevents the bars from becoming too salty.

How do I know when the bars are done baking?

Look for golden edges and a center that’s just set. Avoid overbaking—residual heat continues to cook the bars as they cool. The center should not be jiggly, but slightly soft to the touch.

Are Butterscotch Toffee Cookie Bars freezer-friendly?

Absolutely. Once cooled and sliced, wrap the bars tightly and freeze in a single layer or separated by parchment. They’ll stay fresh for up to two months and thaw beautifully at room temperature.
