Preheat oven to 375 degrees F and line a muffin tin with muffin liners. Set aside.
In a large bowl, whisk together the mix, sugar, baking powder, salt, coconut flakes, and lemon zest. Using a box grater, grate the frozen butter and toss the grated butter into the flour mixture and mix it together. Set aside.
In a small bowl, whisk the coconut milk, egg, and vanilla together.
Combine the dry and wet ingredients. Do not overmix.
When the dough starts to come together, gently fold in the white chocolate chips.
Use a cookie scoop to scoop the dough into the prepared pan.
Bake for 10-14 minutes or until the tops are golden brown and the middle has cooked through.
Cool and enjoy!
