How to Make Cornflake Toffee Cookies
Prepare the Pan: Line a sheet pan with parchment paper. This ensures your cookies won t stick, making cleanup a breeze!
Make the Toffee: In a heavy-bottomed saucepan, combine 40 grams water, 115 grams unsalted butter, 100 grams granulated sugar, and 1/4 teaspoon diamond crystal kosher salt. Heat over medium heat, stirring until the butter melts.
Cook to Temperature: Once melted, let the mixture cook until it reaches 240°F. Use a candy thermometer for accuracy!
Avoid Sugar Crystals: If sugar crystals form on the sides of the pan, don t panic! Wipe them down with a damp pastry brush to keep your toffee smooth.
Finish the Toffee: Continue stirring constantly with a wooden spoon until the mixture reaches 305°F. It should turn a beautiful amber brown color.
Cool the Toffee: Carefully pour the hot toffee onto the prepared parchment-lined sheet pan, then let it set completely.
Store Extra Toffee: If you have any leftover toffee, store it in an air-tight container for future snacks!
Melt the Butter: In a light-colored saucepan over medium heat, melt 280 grams unsalted butter until golden brown, which enhances its flavor.
Whisk in Milk Powder: Add 1 tablespoon + 1 teaspoon milk powder to the melted butter, whisking until fully combined and the mixture becomes aromatic.
Cook the Mixture: Continue to cook and whisk until the milk solids turn a deep umber color and the mixture stops steaming. Transfer it to a heat-proof bowl to cool.
Combine Dry Ingredients: In a medium bowl, whisk together 400 grams all-purpose flour, 2 teaspoons diamond crystal kosher salt, 1/2 teaspoon baking powder, and 3/4 teaspoon baking soda.
Prepare Toppings: Finely chop 100 grams of toffee and mix it with 125 grams of Frosted Flakes in a separate bowl to create your texture blend.
