Cool Homemade 1st Birthday Cake with Wilton Cake Pan

When my son turned 1 year old, I wanted to make him a special 1st Birthday Cake that featured the number 1. I baked a 12×18 sheet cake, then cut out the sides to make a big number one. I frosted the number one white using buttercream frosting, then took those cake pieces that I had cut out from the sides and cut them into five blocks.

I placed those blocks onto the frosted number one, then frosted them too. I edged each block with a color, then added a letter on top of each one. The final touch was to add a bit of color around the edges of the number one, which really made it stand out.

After we sang Happy Birthday to him, Caleb was given just the C block to eat for his special first piece of cake, which made for some cute pictures.

  1. I love your cake! My son turns 1 in Aug. and I’d like to do the same thing. Did you use a cake mix? or 2? Wasn’t sure how much batter for that size pan. Also, where did you find your pan?

  2. Thanks! I did use a boxed cake mix- FOUR, actually! That 12×18 pan take a lot of batter to fill it up enough. I got the pan at Party City, and the directions were on it for how many cups of batter to put in and how long to bake it for. I just followed those directions and it turned out very moist and delicious! Good luck with your cake too!

  3. omg, I’m nervous but want to attempt this cake, I may have my bakery make it, then I could cut out for the blocks & “semi home design it”!! thanks & I hope it turns out!lol!!!

  4. I and my daughter were looking through all the 1st birthday cakes and found yours. Looks simple, yet is adorable. My grandson turns one this weekend and we are excited to make this for him. Thank you for adding that you used four cake mixes. We would have been short, as we were only going to buy two. Thanks again for sharing!

  5. Hi what did you use for the edging on the small blocks on top of the one, l love your design and want to attempt it for my sons 1st birthday in a months time
