Preheat the oven to 350°. Prepare a 9 x 5 inch loaf pan with parchment paper and nonstick spray.
Using a stand mixer fitted with the paddle attachment (or a handheld mixer), beat the butter and the cream cheese on medium high for about 2 minutes or until smooth.
Add the white and brown sugar and beat on medium high for about 1 minute or until well combined. Add the eggs, milk, and vanilla and mix on medium low until just combined.
Add the flour, baking powder, and salt. Mix on the lowest speed until just combined.
If you are using pink food coloring gel take a tooth pick and stick it into the pot of gel. Swirl the tooth pick around in your batter to transfer the food coloring gel. Repeat this again (with a clean toothpick) for a more intense color. Add the raspberries and white chocolate chips and mix on low until just combined.
Pour the batter into the prepared pan. Bake for 90-95 minutes. Check the loaf after about 1 hour and cover loosely with a piece of foil if it is getting too brown.
Remove the loaf from oven and place on a wire rack. Let it cool in the pan completely (2-3 hours).
Whisk the powdered sugar, lemon juice, and lemon zest together until completely smooth.
Drizzle the glaze on to the loaf in the pan after it has cooled. Remove from it from the pan by pulling on the parchment paper and serve.
