Preheat oven to 350° degrees.
Line a cookie sheet with parchment paper. This will keep the cookies from spreading into each other.
In a mixing bowl, add the cake mix, baking powder, eggs and vegetable oil. Mix until well combined.
Stir in the white chocolate chips.
Add the Valentine M&M's and stir to distribute through out the cookie dough.
Using a tablespoon or cookie dough scoop, transfer the dough onto the baking sheet.
Bake at 350 degrees for 10 minutes only. (FYI - If you leave the cookies in longer than 10 minutes, the white chocolate chips begin to brown and the M&M's start to crack)
Let the cookies cool for 5 minutes on the cookie sheet before transferring them to a wire rack to completely cool.
ENJOY!
