• ¼ cup granulated sugar – Enhances sweetness and crispness
• 1 large egg – Binds ingredients and contributes structure
• 1 teaspoon vanilla extract – Adds warmth and flavor depth
• 1½ cups all-purpose flour – Forms the structure of the cookies

Optional Toppings

Step-by-Step Instructions

• Preheat the oven – Set to 350°F (175°C) and line a baking sheet with parchment paper.
• Cream butter and sugars – Beat butter, brown sugar, and granulated sugar for 2–3 minutes until light and fluffy.
• Add egg and vanilla – Mix in the egg and vanilla extract until fully incorporated.
• Combine dry ingredients – Whisk flour, baking soda, and salt in a separate bowl, then gradually fold into the wet mixture until just combined.
• Fold in cornflakes and toffee – Gently incorporate cornflakes and toffee bits, preserving the crunch.
• Scoop the dough – Drop 1-tablespoon-sized balls onto the baking sheet, spacing 2 inches apart.
• Bake the cookies – Bake for 10–12 minutes until edges are lightly golden; centers may look slightly soft.
• Cool and garnish – Allow to cool on the baking sheet for 10 minutes, then transfer to a wire rack. Drizzle with chocolate and sprinkle sea salt if desired.

Recipe Notes & Tips

• Gentle folding – Avoid crushing cornflakes to maintain crunch.
• Softened butter – Ensures even creaming with sugars.
• Check baking time – Remove cookies when edges are lightly golden; centers firm as they cool.
• Spacing on sheet – Allow 2 inches between cookies to prevent spreading.
• Optional toppings – Add chocolate drizzle while warm for easy adhesion.
• Storage – Store in an airtight container at room temperature for up to 5 days.

Slightly underbaking ensures the cookies remain tender inside, while chocolate drizzle or sea salt provides flavor contrast. Each cookie delivers about 180 calories of crunchy, buttery indulgence.
