These chewy white chocolate chip cookies have a secret ingredient - toasted milk powder—the milky caramel notes of this pair perfectly with white chocolate. You can leave it out and still have a perfectly chewy white chocolate chip cookie. But if you're up for it, add the milk powder!
Preheat the oven to 350°F/180°C and line a cookie sheet with parchment paper.
Combine flour, baking soda, baking powder, and salt in a small bowl and whisk. Set this flour mixture aside.
In a large mixing bowl, cream the softened butter, the sugars, toasted milk powder and vanilla.
Next, beat the egg into the sugar mixture until combined.
Add the dry ingredients and white chocolate chips and stir together with a wooden spoon into a thick dough.
Use a cookie scoop or tablespoon to make about 1.5 tablespoons of dough per cookie. Roll the dough into balls and place them on the prepared baking sheet, spaced at least two inches/5 cm apart.
Bake for around 10 minutes until lightly golden brown but still soft. The bake time will depend on your oven.
After baking, while the cookies are still hot, press a few extra white chocolate chips into the top.
