I am trying to get some ideas on what to do for my daughters first birthday cake. Here is the theme I am using. http://www.1stbirthdayparty.com/onderful-birthday-girl-dinner-plate.html

I was thinking about doing a 10x10 cake but will that feed 12 people? And I want to do a little cake for her to eat.

I could use any ideas you may have please!

They have beautiful, fun cakes.

I would do a two tier, 8 inch and 6 inch squares. The bottom one have it pink to match the design around the outside of the plates. Then the top one do the white to match the inside of the plates. I would also have stars and jewels sticking out of the cake on wires and a number one as a "topper". (make sure the wires themselves aren't touching the actual cake, use straws and royal icing to hold the wires) Then for a "smash" cake I would do a number 1. I would also have each cake have a bottom border edge of the green with polka dots.
That's if you really want it to match the plates!!

I think it would be cool to do a round two tiered cake. The circles and colors airbrushed on and then the stars and burst cut out of fondant, and then some stars on wires as a topper.

10x10 single layer square, when cut in 2x2x2" squares means the cake will be cut in 5 rows by 5 columns = 25 pieces.

Plenty of cake.
