Ingredients
Scale
- 1/2 cup unsalted butter, softened
- 1/2 cup granulated sugar
- 3/4 cup light brown sugar
- 1 egg
- 1 teaspoon vanilla extract
- 1 1/2 cups Bob's Red Mill Old Fashioned Rolled Oats
- 1 cup all-purpose flour
- 1/2 teaspoon baking soda
- 1/2 teaspoon Kosher salt
- 2 1/2 cups mini marshmallows, divided
- 2 cups chocolate chips, divided
Instructions
- Preheat oven to 350°F and grease an 11"x8" or 9"x9" baking pan.
- Cream together the butter and sugars in a medium mixing bowl with an electric mixer on medium-high speed until light and fluffy, about 3-4 minutes. Mix in egg and vanilla until fully incorporated, stirring down sides of bowl with a spatula as necessary.
- Add oats, flour, baking soda, and salt and mix on low speed until just combined. Briefly stir in 1 1/2 cups each of mini marshmallows and chocolate chips.
- Scrape out batter into prepared baking pan in an even layer. Bake in oven for 25-30 minutes, until the top is golden brown. The center will still be a bit jiggly, and will set as it cools. Let blondies cool for 10 minutes. T
- Top blondies with remaining 1 cup of marshmallows (feel free to use more as needed to completely cover the blondies in a single layer). Broil marshmallow topped blondies until marshmallows are golden brown and toasted. Remove from oven, melt the remaining 1/2 cup of chocolate chips, and drizzle over marshmallows. Let blondies cool completely (or almost completely) before serving. Devour.
