Step 1: Preheat and Prepare Your Baking Sheet - Start by preheating your oven to 350 degrees. Go ahead and line a large baking sheet with parchment paper so nothing sticks later on. I always do this first because once the dough is ready, you do not want to be scrambling around looking for paper while it sits there getting warm.
Step 2: Mix the Base Dough - In a large bowl, add your cake mix, vanilla extract, egg, softened butter, and cream cheese. Use a hand mixer and blend everything together for about two to three minutes. The dough will be thick and a little sticky, and that is exactly what you want. If the mixer struggles a bit, do not worry. That just means it is coming together properly.
Step 3: Fold in the Mix Ins - Now add your white chocolate chips and freeze dried raspberries. Switch to using your hands or a sturdy spoon and gently fold everything together. The raspberries will break a little, and that is fine, but try not to crush them too much. Those little pockets of raspberry are what make each bite special.
Step 4: Scoop and Shape the Cookies - Scoop out about one and a half inch balls of dough and place them on your prepared baking sheet. Leave about two inches between each one so they have room to spread. Use the palm of your hand or the bottom of a glass to gently press down each cookie just a bit. You are not flattening them completely, just giving them a little head start.
Step 5: Bake Until Just Set - Place the cookies in the oven and bake for ten to twelve minutes. Keep an eye on them toward the end. You want the edges set but the centers still soft. That is what gives them that bakery style texture.
Step 6: Let Them Rest and Enjoy - Once they come out of the oven, let them sit on the baking sheet for about ten minutes. This helps them firm up without overbaking. Then move them to a plate or cooling rack and try to resist eating three in a row. Or do not resist. I never really do.
