For my little brother's 5th birthday I decided I wanted to throw him a real party. I did a baseball theme, so the cake was of course, a Baseball Field Birthday Cake!
I made a chocolate cake in a 9x13" pan and one vanilla cupcake (the rest of the batter I used to make another cake in the shape of a baseball). When the cake was baked and cooled I cut off a few inches from the long side to make a square. Then I frosted the whole cake in green frosting and wrapped thick strips of green fondant around the sides.
With a knife I made an outline in the frosting where the bases would be and filled it in with chocolate cake crumbs from the extra cake that I had cut off. Then I filled a pastry bag with more green frosting, and using the writing tip, I piped an outline around the where I had put the cake crumbs to make it more defined. Then I piped the grass, using the same tip.
I cut off a part of the bottom of the cupcake and smushed it a little to make it rounder. Then I frosted it in white and made the strings with red frosting. And last, but not least were the bases, which I made with white frosting piped in the shape of the bases and then filled in.
My son turned 5 this year and just finished his first season of baseball. He specifically asked for a baseball field cake, so this is what I came up with.
I used a 12x12 square cake pan, and just trimmed two sides to make it the shape of a baseball field. I crushed up graham crackers for the dirt. I would also recommend that you put the dirt go on last. If you put the dirt on first, as you add the grass (using the Wilton grass tip), it will pick up the crumbs and not stick to the cake.
I added the bases and lines on top of the 'dirt' with white decorators icing (the kind in the tube) and topped it off with a baseball (I used the mini ball pan and put two halves together). I had to cut off a small amount of the bottom of the baseball to ensure it would stay on the cake.
For my nephew Theo's 3rd birthday, he asked for a Baseball Field Cake. I baked an 8" round and an 8" square chocolate cake. After they cooled I wrapped and froze them. Frozen cakes are much easier to handle and decorate. I cut each cake in half and put round and square together, joining them at the cut edge.
Then I filled the cake with chocolate icing and topped it with the second layer. I frosted the top of the cake with chocolate icing, and sides with white butter cream tinted green. And used a star tip for the grass. The white lines were piped on to complete the field.
My husband printed a scoreboard on the computer. We taped it to a piece of cardboard and 2 lollipop sticks. I wanted to put some plastic baseball players on the field but couldn't find any that were the right size.
The birthday boy loved it anyways! It was a big hit with everyone.
