Ingredients

Here’s what you’ll need to whip up these delicious blondies:

1 cup unsalted butter, melted: Gives that rich, buttery base that’s essential for chewy blondies.
2 cups packed brown sugar: Adds sweetness and moisture, plus that deep caramel-like flavor.
2 large eggs: Binds everything together and adds to the chewiness.
2 teaspoons pure vanilla extract: Enhances the butterscotch flavor with a warm, fragrant note.
2 cups all-purpose flour: The structure of your blondies.
½ teaspoon baking powder: Just enough lift to keep them from being too dense.
½ teaspoon salt: Balances the sweetness and enhances flavor.
1½ cups butterscotch chips: The star of the show, melting beautifully into each bite.

How to Make Grandma’s Chewy Butterscotch Blondies

Ready to get baking? Let’s walk through it step-by-step:

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan or line it with parchment paper, leaving an overhang to make removing the blondies a breeze.
In a large bowl, mix the melted butter and packed brown sugar until the mixture is smooth and glossy — this is where the magic begins!
Add the eggs and vanilla extract, then beat well until your batter looks shiny and fully combined.
Stir in the flour, baking powder, and salt just until everything is combined — be careful not to overmix or your blondies might turn out tough.
Gently fold in the butterscotch chips, making sure they’re evenly spread through the batter.
Pour the batter into your prepared pan and smooth the top with a spatula for even baking.
Bake for 25 to 30 minutes. You want the edges to be lightly golden and set, with the center still soft but not jiggly — that’s the key to chewy blondies!
Allow the blondies to cool completely before slicing into squares. This helps them hold together and prevents crumbling.

Substitutions & Additions

Feel like mixing things up or adapting to what you have on hand? Here are some ideas:

Swap butterscotch chips for white chocolate chips or semi-sweet chocolate chips for a different but still delicious twist.
Add chopped nuts like pecans or walnuts for a delightful crunch and extra texture.
For a fun seasonal touch, sprinkle mini marshmallows on top before baking — they’ll get slightly toasted and gooey, similar to this no-bake marshmallow slice.
If you want to make these gluten-free, try swapping the all-purpose flour for a 1:1 gluten-free baking flour blend.

Tips for Success

Don’t overmix the batter. Once you add the flour, gently fold until just combined to keep your blondies tender.
Watch your baking time carefully. Every oven bakes a little differently, so start checking at 25 minutes. The center should be soft but not gooey.
Line your pan with parchment paper. This makes lifting the blondies out easy and keeps the edges from getting too crispy.
Let them cool completely. It may be tempting to dig in right away, but cooling helps them set perfectly.
Prep ahead. You can mix the batter the night before and keep it covered in the fridge. Just give it a gentle stir before baking.

How to Store Grandma’s Chewy Butterscotch Blondies

Once baked and cooled, you want to keep these blondies fresh and chewy. Here’s how:

Store them in an airtight container at room temperature for up to 4 days.
If you need to keep them longer, you can freeze the blondies cut into squares for up to 3 months. Thaw them at room temperature before serving.
To keep them soft, place a slice of bread in the container with the blondies — it helps retain moisture!

FAQs

Can I use salted butter instead of unsalted?: Yes, just skip adding extra salt or reduce it slightly since salted butter adds some saltiness already.
What makes blondies chewy instead of cakey?: The combination of melted butter, brown sugar, and careful mixing creates that moist, chewy texture rather than a light and fluffy one.
Can I add other mix-ins besides butterscotch chips?: Absolutely! Chocolate chips, nuts, or even dried fruit can be great additions to customize your blondies.
How do I know when the blondies are done?: Look for golden edges and a slightly soft center that’s not jiggly. A toothpick inserted should come out with a few moist crumbs, not wet batter.

If you love recipes that bring that classic, cozy feeling with a sweet twist, you might also enjoy trying some of my other favorites like the no-bake orange creamsicle cheesecake or even experimenting with different baking pans like in this guide on baking brownies in a bread pan to mix up your baking routine.
