For the funfetti dough: Add milk, butter, and sugar to a small pot; mix and warm up over medium heat just until butter melts. Add the flour, yeast, salt, and eggs into a stand mixer’s bowl. Mix on lowest speed with hook attachment just until combined. Pour in the melted butter/milk/sugar mixture in a slow thin stream while the mixer is going on low speed. Increase the speed to medium-high and knead for 10 minutes. Stop the mixer, add sprinkles and mix on low speed just until combined.
Warm up the oven to 200F, then turn it off. Transfer the dough into a separate greased bowl; cover with kitchen plastic, towel, and allow to rise in the warm oven for 2 hours.
To make the filling: whisk together the melted butter, sugars and cinnamon; set aside.
To make the frosting: whip the cream cheese and butter in a stand mixer fitted with the paddle attachment, 5 min. Reduce the mixer's speed to lowest and add vanilla, salt, powdered sugar, and pink food coloring. Mix until combined.
Once the dough has risen, roll it into a 1/4" thick rectangle. Evenly spread the cinnamon filling and top with sprinkles (if desired). Starting from the shorter end, roll the dough into a tight log. Slice into 1" pieces using a thread and arrange in a greased bunny pan; cover with plastic and towel, and place into warm oven for 30 minutes.
Once rolls have risen, bake on 350°F on middle rack for 15-18 minutes. Spread the cream cheese frosting and sprinkles while the rolls are still warm. Enjoy!🐰🎊
