Grandma's Chewy Butterscotch Blondies

Why You’ll Love This Recipe

I love this recipe for how perfectly soft and chewy the blondies turn out, with just the right balance of sweetness and texture. The butterscotch chips melt into gooey pockets throughout the bars, and the brown sugar gives the whole batch a caramel-like depth. It’s a one-bowl recipe with no mixer needed, and it’s great for parties, bake sales, or just a weeknight dessert craving.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

1 cup unsalted butter, melted
2 cups brown sugar, packed
2 large eggs
2 teaspoons vanilla extract
2 cups all-purpose flour
1/2 teaspoon baking powder
1/2 teaspoon salt
1 1/2 cups butterscotch chips

Directions

I start by mixing the melted butter and brown sugar together in a large bowl until smooth and glossy.
Then I add the eggs and vanilla extract, stirring until everything is fully combined.
I gently stir in the flour, baking powder, and salt until the batter is just mixed.
Once the base is ready, I fold in the butterscotch chips evenly.
I spread the batter into a greased 9×13-inch baking pan, making sure it’s leveled out to bake evenly.
I bake it in a preheated oven at 350°F (175°C) for 25 to 30 minutes, or until the top is golden and a toothpick comes out with a few moist crumbs.
After baking, I let the blondies cool completely in the pan before cutting them into squares for serving.

Servings and timing

This recipe makes about 24 blondie squares. From start to finish, it takes around 40 minutes — about 10 minutes of prep time and 25 to 30 minutes of baking.

Variations

I sometimes swap half the butterscotch chips for chocolate chips when I want a richer flavor. If I’m feeling festive, I add chopped pecans or walnuts for some crunch. For a salted twist, I like to sprinkle a pinch of flaky sea salt on top before baking. It’s also easy to cut this recipe in half for a smaller batch using an 8×8-inch pan.

Storage/Reheating

Once cooled, I store the blondies in an airtight container at room temperature for up to 5 days. They stay soft and chewy. If I want to reheat them, I just pop a square in the microwave for 10–15 seconds to bring back that fresh-baked texture. They also freeze well — I wrap them individually and store in a freezer bag for up to 2 months.

FAQs

How do I know when the blondies are done baking?

I check for a golden top and use a toothpick — if it comes out with a few moist crumbs (not wet batter), they’re ready.

Can I use salted butter instead of unsalted?

Yes, I’ve done that in a pinch. I just reduce the added salt to about 1/4 teaspoon.

Can I make these blondies gluten-free?

Absolutely. I substitute the flour with a 1:1 gluten-free baking flour blend and the results are still delicious.

Why are my blondies too cakey?

If I overmix the batter or bake too long, they can turn cakey. I mix just until combined and keep an eye on the bake time.

Can I double this recipe for a crowd?

Yes, I double the ingredients and use two 9×13-inch pans or a larger sheet pan. I just watch the bake time since it may vary slightly.

Conclusion

Grandma’s Chewy Butterscotch Blondies are a timeless treat that always brings a sense of comfort and joy to the table. I love how easy they are to make and how every bite delivers that chewy, buttery sweetness. Whether for a holiday, a special occasion, or just a cozy afternoon, these blondies are always a hit.
