The Ultimate Rainbow Cake Singapore

Rainbows symbolise peace, love and the sweetest moments - they’re common blessings given at birthday parties and baby showers alike. Whether it be for a christening cake, baby’s full month cake, baby shower cake, baby girl’s first birthday cake, or young girls’ cakes, Bob the Baker Boy has a Rainbow Cake catered to every occasion!

Expect to see an explosion of colours if you’re looking for a 1st birthday cake for girls or 1st birthday cake for boys. We use food colors of the highest quality in our cake recipe. With some extra cake pans, our signature vanilla cake layers, powdered sugar and a little magic, we delight kids with a beautiful mix of red, orange, yellow, green and blue!

Our cake recipe is lower in sugar and contains no maple syrup in the cake mix - perfect for your precious little ones! We’ve got a wide range of Rainbow Cakes - from vibrant and colorful, to abstract and less literal - all while being equally scrumptious!
