Make a pack of buttercake or vanilla cake mix, whichever you prefer, according to directions. Pour mixture into 12 muffin cases and cook as directed.
Now to make the vienna cream icing :)
You need 125g butter, 1.5 cups icing sugar, 1tbs milk.
Using an electric mixer, beat butter until pale and creamy. Gradually add in all the icing sugar and milk.
I didn't add any flavouring as it is very sweet and tasty as is. I added pink food coloring but yellow also looks good.
After allowing the cupcakes to cool, spread the vienna cream icing onto each cake.
Now for decorating XD
Get a bag of mixed colors marshmallows. Each cupcake needs 5 petals/2.5 marshmallows. Cut each marshmallow in half with scissors/a knife. Squeeze both the end of the marshmallow to make it look more like a petal. Press onto icing.
I added some pink sprinkles onto some of the cupcakes for more pink :D
Add a smartie/chocolate bud in the middle of each cupcake for the centre of the flower.
