Prepare the vanilla cake mix according to the directions on the box.
Allow the cake to cool completely.
Crumble the cooled cake into fine crumbs in a large bowl.
Add the softened butter, eggs, milk, and vanilla extract to the cake crumbs and mix well.
Form the mixture into small balls and place them on a baking sheet lined with parchment paper.
Place the baking sheet in the refrigerator for about 30 minutes to firm up the cake pops.
In a separate bowl, whisk together the powdered sugar, milk, and vanilla extract until smooth.
Dip each cake pop into the glaze, allowing any excess to drip off.
Decorate the cake pops with sprinkles or other decorations of your choice.
Place the decorated cake pops back on the baking sheet and allow the glaze to set.
Serve and enjoy!
