My go to easy buttercream frosting recipe is by Canadian Living. It is rather sweet but it spreads nicely and is super easy. http://www.canadianliving.com/food/vanilla_buttercream_icing.php
I made my recipe according to the recipe and then set aside about 3/4 cup of frosting to keep white. I added the raspberry syrup to the remaining frosting. to maintain the consistency, I added a few spoonful's of sifted icing sugar. The frosting picked up a subtle pink hue. Sadly, not as pink as I would have liked for my cake, so I ended up using a teensy bit of store bought food colouring gel to deepen the pink colour. Ah well! The frosting did change colour and it had a hint of raspberry flavour too which was quite lovely. If I had been making a regular layer cake and not one for a theme cake, the natural frosting would have been perfect. Next time, I will see if increasing the volume of raspberry syrup and thickening it a bit with cornstarch while cooking it will allow me to add more colour without diluting my frosting. I will keep you posted.
Making the Cat Cake
Pink Frosting for entire cake and ears
White frosting for cheeks, chine, eyes and whiskers (I set aside about 1 cup of white frosting before tintin
Licorice shoe string snipped super short for whisker dots, eye dots, and mouth
TWO round green wine gums, sliced thinly
3 Ice cream sandwich wafers (Bulk Barn) or large graham crackers, cut into triangles with a serrated knife - 2 large and 2 small for the contrast
What To Do:
Ice your cake like you would for any layer cake with the pink frosting. Put short slits into the cake where you want the ears to go. Spread a little frosting on the bottom of the triangles and gently press into the slits you made. Frost the ears, front and back.
With the back of a spoon or an offset spatula, pat the icing all over to make the icing look "fluffy".
With a large piping tip, pipe 2 large cheeks, a chin, and 2 eyes.
Place nose above cheeks, insert the licorice mouth, and pipe the whiskers. Carefully place the whisker dots on the cheeks.
Gently press the green eyes on the piped eyes, and then then place the eye dots on.
Take the smaller triangles and gently press onto the ears for the contrast.
