Health Benefits of the Stars: A Closer Look at the Ingredients
While these blondies are undeniably indulgent, let’s highlight the good stuff! Brown sugar offers a slightly more complex flavor profile than white sugar and contains small amounts of molasses, which adds a touch of iron and antioxidants. Butterscotch chips, while sweet, add a rich, caramel-like flavor. And don’t forget the wholesome goodness (okay, maybe not so wholesome!) of the marshmallows and white chocolate for extra happiness. Remember, moderation is key when indulging in treats like this!
A personal touch: My grandmother used to make blondies for every family gathering, and the kitchen always smelled magical. This recipe is my updated version of her classic, with added butterscotch and marshmallows for extra joy.

Making Magic: Step-by-Step Instructions for Butterscotch Marshmallow Blondies
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C). Line your 8×8 or 11×7 inch baking dish with foil, leaving an overhang on the sides to help with lifting out the finished blondies. Spray the foil with cooking spray to prevent sticking. Tip: Using foil makes for super easy cleanup!
Step 2: Melt the Butterscotch Bliss
In a small saucepan over low heat, melt the butter and butterscotch chips together, stirring frequently until smooth and completely melted. Remove from heat and set aside to cool slightly. Tip: Low and slow is key to preventing burning!
Step 3: Dry Ingredients Unite
In a large bowl, whisk together the flour, salt, baking powder, and brown sugar until well combined. This ensures even distribution of the leavening agents. Tip: Make sure there are no lumps of brown sugar.
Step 4: Bringing it All Together
Add the cooled butterscotch mixture to the dry ingredients and stir until just combined. Be careful not to overmix; a few lumps are okay. Tip: Don’t overmix the batter. Overmixing can lead to tough blondies.
Step 5: Wet Ingredients and Mix-ins
Stir in the egg and vanilla extract until the batter is smooth. Then, gently fold in the marshmallows and white chocolate chips. Tip: Be gentle when folding in the marshmallows to avoid breaking them.
Step 6: Bake to Perfection
Spread the batter evenly into the prepared pan. Bake for 20-25 minutes, or until a toothpick inserted into the center comes out with just a few moist crumbs attached. Don’t overbake, or you’ll end up with dry blondies. Tip: Oven temperatures can vary, so keep an eye on them towards the end of the baking time.
Step 7: Cool and Enjoy!
Let the Butterscotch Marshmallow Blondies cool completely in the pan before lifting them out using the foil overhang. Once completely cool, cut into squares and enjoy! Tip: Cooling completely prevents the blondies from crumbling when you cut them.
Storage and Serving Suggestions
Store leftover Butterscotch Marshmallow Blondies in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week. They are delicious served at room temperature or slightly warmed up.
