These were so easy it's not even funny.
I used a pound cake box mix and baked them in a mini muffin pan. After levelling off the top flip them over and place on cooling rack. Once completely cool put cooling rack over cookie sheet. Mix up glaze and pour over. Make sure you cover every bit of cake because it's impossible or very hard to touch up without it looking yucky. The coating is very thick and sweet, but I got only raves on flavor. Let dry for an hour or two and gently move to cupcake papers with a large offset spatula. I used regular buttercream to do the rose buds and calyx on top.
6 C powdered sugar
1/2 C water
2 T corn syrup
1 t vanilla or almost extract
Mix together. Adjust thickness by adding powdered sugar to make thicker or water to make thinner. Should be really thick, but pourable. I do not heat mine at all.
You can fill these with a bag and tip just like you would cupcakes.
Hope that helps.
