Carrot Cake Poke Cake is an incredibly easy and delicious cake, made using cake mix, and topped with a thick layer of mascarpone cream cheese frosting.
Preheat oven to 350°F. Place the oven rack in the middle of the oven.
Remove cake from the oven. Using the end of a spatula or a large straw, even a pen will work if you don't have anything on hand; poke holes all over the cake.
In a medium, microwave-safe bowl, combine white chocolate chips and sweetened condensed milk. Heat in the microwave until hot for about 1 minute. Stir and heat 30 seconds or more if needed. Whisk until fully combined, smooth and shiny.
