Ingredients
Scale
- 1 cup unsalted butter, softened
- 1 cup packed light brown sugar
- 1/2 cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 2 1/2 cups all-purpose flour
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1 cup butterscotch chips
- 1 cup toffee bits (look for sturdy ones that hold up in baking)
- Optional substitution: For a gluten-free version, swap the all-purpose flour with a 1-to-1 gluten-free baking flour blend.
- Optional substitution: Use coconut oil in place of butter for a dairy-free twist, but expect a slightly different texture.
Instructions
- Preheat your oven to 350°F (175°C) and line a 9×13-inch baking pan with parchment paper, leaving some overhang for easy removal later. This step always reminds me of my grandmother’s meticulous preparation—it’s the small things that make cleanup and serving so much easier.
- In a large bowl, cream together the softened butter, light brown sugar, and granulated sugar until the mixture is light, fluffy, and well combined—about 3 to 4 minutes. I like to use an electric mixer for this, but a sturdy wooden spoon works just fine if you want a little upper body workout!
- Beat in the eggs one at a time, making sure each is fully incorporated before adding the next. Then stir in the vanilla extract. The aroma at this point always fills my kitchen with that comforting, “home is here” feeling.
- In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. Slowly add the dry ingredients to the wet mixture, mixing just until combined. Over-mixing can make the bars tough, so I always remind myself to stop as soon as the flour disappears.
- Fold in the butterscotch chips and toffee bits gently, saving a handful of each to sprinkle on top before baking. This extra touch always makes the bars look as good as they taste, and my kids love being part of this step—it’s our little tradition.
- Press the dough evenly into your prepared baking pan. This is where I find using a piece of parchment paper or a flat spatula helps to smooth the surface without sticking to your hands.
- Sprinkle the reserved butterscotch chips and toffee bits evenly on top, pressing them lightly into the dough. This creates those irresistible pockets of gooey sweetness once baked.
- Bake for 25 to 30 minutes, or until the top is golden brown and a toothpick inserted near the center comes out with just a few moist crumbs. I’ve learned from experience that ovens vary, so keep an eye starting around 22 minutes to avoid overbaking.
- Allow the bars to cool completely in the pan on a wire rack. This patience is tough, especially when the smell is tempting everyone nearby, but it’s crucial for clean slices and the perfect chewy texture.
- Once cooled, lift the bars out using the parchment overhang and cut into 16 squares. Serve with a big glass of milk, or share with family and friends to make those everyday moments a little sweeter.
