Bedrock is throwing a birthday party! To celebrate its 50th birthday this year, PEBBLES cereal is launching a new limited-edition Birthday Cake PEBBLES cereal featuring festive, colorful flakes in blue, pink and yellow, and a classic vanilla birthday cake and frosting flavor. The new cereal will begin rolling out nationwide in April and will be available while supplies last.

“When it comes to birthdays, there’s nothing more iconic than a colorful cake,” said Amy Brothers, PEBBLES Cereal Brand Manager at Post Consumer Brands. “Our new Birthday Cake PEBBLES cereal is a fun and delicious twist on the traditional birthday cake, and is just one more way we’re celebrating with fans and keeping PEBBLES 50th birthday party going this year. Plus, all PEBBLES cereal varieties are gluten-free, so everyone can partake in the celebration.” 

The new Birthday Cake PEBBLES cereal is available in three package sizes – 10 ounces, 19 ounces and 40 ounces. Each box features a recipe for Dinosaur Egg Cake Pops and Flintstones-inspired Stone Age party games on the back.
