Equipment

Ingredients

2 cups (80 g) cornflakes
1 cup (226 g) unsalted butter softened
1 cup (200 g) light brown sugar firmly packed
½ cup (100 g) granulated sugar
1 large egg + 1 egg yolk room temperature preferred
1 ½ teaspoons vanilla extract
2 ¾ cups (350 g) all-purpose flour
1 Tablespoon cornstarch
1 teaspoon baking soda
1 teaspoon table salt
1 ½ cups (85 g) mini marshmallows

Instructions

Preheat oven to 350F (175C) and line a baking sheet with parchment paper. Set aside.
Once oven is preheated, spread cornflakes evenly over a baking sheet and transfer to center rack of oven, bake for 10-15 minutes, checking and stirring every 5 minutes until cornflakes are toasted and have darkened slightly in color (after the 10 minute mark, keep a close eye if they need additional time as they can burn fast). Set aside to cool while you prepare the cookies.
2 cups cornflakes
In a large mixing bowl, use an electric mixer to cream together butter and sugars.
1 cup unsalted butter, 1 cup light brown sugar, ½ cup granulated sugar
Add egg, egg yolk, and vanilla extract and stir to combine.
1 large egg + 1 egg yolk, 1 ½ teaspoons vanilla extract
In a separate mixing bowl, whisk together flour, cornstarch, baking soda, and salt.
2 ¾ cups all-purpose flour, 1 Tablespoon cornstarch, 1 teaspoon baking soda, 1 teaspoon table salt
Gradually add flour mixture to butter mixture, stirring thoroughly after each addition until all ingredients are thoroughly combined.
Add the toasted cornflakes and mini marshmallows and use a spatula to fold together ingredients until evenly distributed.
1 ½ cups mini marshmallows
Scoop dough by 2 Tablespoon-sized scoops (40g) and roll gently between your palms to form a smooth ball. Place on baking sheet, spacing cookies at least 2” (5cm) apart and transfer to center rack of 350F (175C) preheated oven for 10-11 minutes, until the edges just start to turn a light golden brown.
Allow to cool completely on baking sheet before enjoying!
