Ingredients

• 280 grams all-purpose flour
• 1 teaspoon baking soda
• 1 1/2 teaspoons cornstarch
• 1/2 teaspoon salt
• 170 grams unsalted butter, melted
• 135 grams brown sugar
• 100 grams granulated sugar
• 1 large egg
• 2 teaspoons vanilla extract
• 150 grams chocolate chunks or crushed peanut M&Ms

Instructions

1. Melt the butter in a small sauce pan. Once melted put off to the side to cool to room temperature.
2. Mix the flour, baking soda, cornstarch, and salt in a large bowl.
3. In another bowl, mix the melted butter and sugar together. Add the egg and vanilla. Mix until the egg is fully incorporated.
4. Pour the wet ingredients into the dry ingredients and mix until just combined.
5. Add the chocolate chunks.
6. Ball the dough, about 40g each. Refigerate the dough for at least 2 hours but ideally overnight.
7. Preheat the oven to 160°C. Once heated, bake the cookies for 12 minutes. They'll look underbaked, but don't worry!
