I used 4 layers of 8x8 cakes to make each block (1 box mix of cake filled two 8x8 pans). I just trimmed off all four sides to make a nice flat edge and used buttercream icing.
I used candy melts to make the letters and characters. Just melted them in a ziploc bag in the microwave and added my food coloring. Then snipped the corner off and traced my pattern on the wax paper. Make sure to use skewers in the baby blocks cake so it doesn't fall over.
I made this Baby Block cake for my daughter's first birthday. I used 4 square cakes, layered. I did use a cake leveling tool to ensure the cakes layered nicely.
I used a mini loaf pan cut in half and then layered for the "smash" cake. I liked the look of fondant, but don't care for the taste, so to make this cake smooth, I dipped my spatula in hot water, dried it and then smoothed the cake. It's also a must to do a crumb coat.
I made this ABC Blocks Shower Cake for my daughter in law's baby shower. I made 3 13x9 sheet cakes, cut them into squares and stacked them into the block shapes. I placed the bottom two blocks and iced, then placed the 3rd block on top before icing it.
I used homemade buttercream frosting (my family dislikes fondant), iced them very smooth, and spelled out the baby's name. I used a tootpick to lightly trace the letters in the icing before piping them on.
This is a Baby blocks cake that I made for my Daughter, and the theme was rubber duckies. So I made baby blocks and frosted each one in pastel colors,(with buttercream icing)and wrote B A B Y on each one.
Next I added the rubber duckies and lots of icing bubbles all over the blocks and board. This cake was very easy to make and everyone loved it. "Welcome Baby Brooklyn"
