Place your cake or cupcakes in the freezer overnight.
Roughly chop frozen cake into small cubes.
In a large bowl whip cream on high until stiff peaks form.
No mixer? No problem! Whisk in a chilled bowl instead.
Stir in sweetened condensed milk and vanilla.
Fold in cake cubes and sprinkles.
Pour into a loaf pan. Top with additional sprinkles if desired.
Freeze for 4-6 hours
