For the cake pops, finely crumble the cake. Mix the butter with the powdered sugar and cream cheese and rum until creamy.
Now add enough of the cream to the cake crumbs to make a soft mass that does not stick to your hands, but also does not fall apart.
Form 18 equal-sized balls from the mixture and chill in the refrigerator for about 15 minutes. In the meantime, melt the chocolate coating.
Remove the balls from the refrigerator and dip a wooden stick about 1 cm into the chocolate coating and stick it into one ball.
Continue in this way with all the balls. Chill again for about 15 minutes. Then dip the balls into the chocolate coating and distribute the chocolate evenly over the balls by turning and shaking them.
While the chocolate is still soft, decorate the cake pops with the cake decorations.
