In the bowl of a stand mixer , add butter, brown sugar, sweetener, vanilla extract, orange extract, egg, and applesauce. Mix on medium-high speed until combined.
Then, add the flour and protein powder and mix on low just until the dry ingredients are combined. Fold in the white chocolate chips and dried cranberries.
Pour batter into the prepared dish and even out so the top is smooth. Place the pan in the oven and bake for 15-20 minutes or until a toothpick inserted in the center comes out mostly clean.
