Ingredients
Method
- Line an 8x8-inch baking pan with parchment paper, leaving some overhang on the sides.
- In a large microwave-safe bowl, melt the white chocolate chips in 30-second intervals, stirring between each interval until smooth.
- In a separate bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy.
- Add the vanilla extract, sweetened condensed milk, and salt to the butter mixture and blend until smooth.
- Gradually fold in the heat-treated flour until just incorporated.
- Stir in the mini chocolate chips, reserving a few tablespoons for topping.
- Pour the melted white chocolate into the cookie dough mixture and fold gently until just combined.
- Transfer the mixture to the prepared pan, spreading it evenly and sprinkling reserved chocolate chips on top.
- Refrigerate for at least 3 hours or until completely firm.
Notes
Remember to heat-treat your flour before using it. Store in an airtight container in the refrigerator for up to two weeks or freeze for up to three months.
