If you're searching for a creative birthday cake idea for your favourite prince or princess, avoid cake crumbs and create a castle with Rice Krispie treats. No matter how many desserts you have constructed, a Rice Krispie treat castle will stand out as memorable. The gooey consistency, sweet flavour and unusual presentation will rival cupcake and cake towers. The sticky texture and thickness of Rice Krispie treats allow for simple construction, since the treats stack easily to form tower-like structures.

Cool four batches of Rice Krispie treats. Place one batch on a large cake plate or tray to form the bottom layer of the castle. Use an icing spatula to spread a layer of frosting on top, then add another batch of Rice Krispie treats on top of the first layer for extra height.

Cut 2-inch squares of Rice Krispie treats with a serrated knife to form turrets. Stack the squares onto each corner of the castle, alternating between frosting and treats so the squares stick together.

Cut and stack two or three 4-inch squares in the middle of the tower to represent the castle's keep. Cut 1-inch squares to stack at the corners of the keep to create turrets.

Frost the Rice Krispie tower, if desired. Pipe frosting, using a frosting bag, onto the tower to create details such as an arched door, crawling vines and decorated turrets

Top the Rice Krispie turrets with frosted, upside-down ice cream cones to resemble spires. Place a miniature flag at the top of each spire. Add an upside down ice cream cone in the middle of the keep with a flag sticking out of it.


Embellish the Rice Krispie castle with candy such as gumdrops and lollipops for added colour and detail.
