• Preheat oven to 350 degrees. Prep a 9x5 loaf pan with nonstick baking spray. Cream the butter and sugar together in a large bowl until it becomes light and fluffy. Mix in the eggs and vanilla until just combined. Add the sour cream and milk. Beat until everything is incorporated.
• Whisk the dry ingredients together in a large bowl. Slowly add the dry ingredients to the wet ingredients. Stir until just combined. Use a rubber spatula to add the sprinkles. Do not overstir. Spoon the batter into the prepared loaf pan. Spread until the top of the loaf is even.
• Bake at 350 degrees for 60 to 70 minutes. Check by inserting a toothpick in the center. Set it aside to cool for 5 minutes. Take the loaf out of the pan and place it on a wire rack to cool completely.

Glaze:

• Add powdered sugar, heavy cream, and vanilla in a medium bowl. Whisk to make the glaze. Pour the glaze over the bread. Top with Christmas sprinkles.
