My son wanted to have a birthday party themed after his favorite toy- LEGOS! The supplies I used for this Homemade LEGO Birthday Cake: Pillsbury Funfetti box cake mix, my own homemade butter cream frosting recipe, Wilton Ready-to-use rolled fondant in primary colors and white, Play-Doh letter cutters, and actual toy LEGO bricks of various sizes (don't worry I washed the toys).
I used 2 cake mixes. I poured about an inch of the batter into one 9x12 cake pan, one 9x9 cake round, and the remainder into cup cakes (I followed the box directions for baking). For the 9x12 green LEGO brick cake I just waited until it was cool, cut 3 shallow holes on top, and set a cupcake in each hole. I dyed butter cream frosting green (my son's favorite color) and covered the whole thing. Next I decorated the round 9x9 individual birthday boy cake. I covered the cake in butter cream frosting and let it chill in the fridge while I prepared the white fondant. I put vanilla flavoring in mine for a better taste. I put the layer of white fondant on the cake and trimmed the excess around the edges with a pizza cutter. I opened the packages of colored fondant, rolled out the blue fondant and used Play-Doh letter cutters to make "HAPPY BIRTHDAY CONNER - 5." Then rolled out the other colors of fondant. I took LEGO bricks of various sizes and gently pressed them into the fondant (face up) to make impressions that looked like LEGO bricks. I cut around the bricks with a butter knife and gently placed them onto the cake at various angles. I did this on some plain white frosted cupcakes as well. I used the leftover fondant scraps to make a trim around the bottom of the cake. I just rolled chunks into marble sized balls and placed them along the bottom, tried not to repeat the same color in a row.
It was really fun to make, and Conner loved his LEGO birthday!
