Marshmallow Toffee Blondies

Why These Marshmallow Toffee Blondies Are My Go-To Chewy Bar

Marshmallow Toffee Blondies are my favorite when I want a chewy, buttery bar packed with mix-ins. The combination of melty marshmallows, crunchy toffee bits, and semi-sweet chocolate chips in a soft brown sugar base is hard to beat. Best of all, they come together in one bowl and bake in about 30 minutes.

Three Reasons These Easy Blondies Win Every Time

• Gooey marshmallow pockets get slightly toasted on top for a s’mores-like touch.
• Toffee bits add a buttery crunch that contrasts with the soft chewy base.
• You only need one bowl and a spoon, no mixer required if you melt butter and stir by hand.

Key Ingredients for These Chewy Blondies

• Brown sugar: Provides moisture and a deep caramel flavor that makes these blondies chewy. Use light or dark; dark gives more intense flavor. Do not substitute with granulated sugar.
• Mini marshmallows: They melt into gooey pockets. Regular marshmallows cut into pieces work too, but mini ones distribute more evenly.
• Toffee bits: Look for English toffee bits in the baking aisle, or chop up Heath or Skor bars. They add buttery crunch.

Kitchen Tools for Making Toffee Blondies

• 9×13-inch baking pan
• Stand mixer or hand mixer (or a large bowl and wooden spoon)
• Rubber spatula for pressing dough evenly

Tips for Perfectly Chewy Blondies Every Time

For the chewiest blondies, mix the batter just until the flour disappears. Overmixing can make them tough. Use room temperature eggs so they blend evenly into the butter and sugar. When you press the dough into the pan, wet your hands slightly to prevent sticking. Sprinkle a little sea salt on top before baking, it balances the sweetness. Bake until the edges are golden and the center is just set, about 30 to 32 minutes. A toothpick inserted near the center should come out with a few moist crumbs, not raw batter.

Understanding What Makes These Blondies Special

Brown sugar is key to the texture and flavor. It provides both sweetness and moisture, which gives these blondies their signature chew. If you substitute granulated sugar, the bars will turn out crisper. Toffee bits are widely available, but you can also chop up Heath or Skor candy bars for the same effect, they melt slightly and create little caramelized pockets. Mini marshmallows distribute more evenly than larger ones, so you get a bit in every bite.

Marshmallow Blondies Variations to Try

Swap the semi-sweet chocolate chips for milk chocolate or white chocolate for a different flavor. Add half a cup of chopped pecans or walnuts for extra crunch. If you love peanut butter and chocolate, drizzle melted peanut butter over the batter before baking. For a spicy twist, add a quarter teaspoon of cinnamon to the dry ingredients.

Best Ways to Serve Toffee Blondies

Serve these blondies warm with a scoop of vanilla ice cream for an indulgent dessert. They’re also great with a cold glass of milk or a cup of coffee. For game day, arrange them on a platter with other finger desserts, they hold up well at room temperature and travel easily.

How to Store Leftover Chocolate Chip Blondies

Store the blondies in an airtight container at room temperature for up to 5 days. If you need to stack them, place a sheet of wax paper between layers to prevent sticking. They’ll stay soft and chewy.

Can You Freeze Marshmallow Toffee Blondies?

To freeze, wrap the cooled blondies individually in plastic wrap, then place in a freezer-safe bag. They’ll keep for up to 3 months. Thaw at room temperature or warm briefly in the microwave before serving.

Best Way to Reheat Blondies for That Fresh-Baked Taste

For just-baked warmth, reheat individual blondies in the microwave for 10 to 15 seconds, or place them on a baking sheet in a 300°F oven for 5 minutes. The marshmallows will get gooey again.
