What is five feet long, weighs 200 pounds and serves 700 people?
Answer: Barrie's Canada 150 birthday cake.
The masterpiece is being finalized as we speak at Cakes By Design on Toronto St.
"The design is very celebratory," said shop owner Jennifer Mayrl. "It has to serve two purposes: look really cool but be easy enough to slice for everyone."
The large dessert is made with 150 eggs, 50 pounds of flour and close to 40 pounds of butter cream frosting alone in addition to fondant and royal icing.
The details of the design are a secret but Mayrl did reveal the flavour is red velvet.
"This year we're sticking with a red theme for Canada's 150. We're doing the whole cake red velvet. It's just Canadian," she said.
Her team is working to the Saturday deadline and only so much of the massive cake can be made in advance to keep it fresh.
The cake will be about five feet long and two and a half feet high.
And will weigh a lot.
"Normally the cake is a couple of hundred pounds. We get about four guys to lift it because it weighs that much and then we add some additional cakes too," explains Mayrl.
"We end up making multiple slab cakes and tiered cakes so it's not baked as one big cake. We bake it as multiple smaller cakes and then assemble them together so it looks like one big cake in the end."
The giant birthday cake will be served on a 60 inch by 30 inch board that will be carefully loaded into Maryl's SUV to be transported downtown.
"We make enough cake that you could probably serve, depending how big they're going to cut, but I would say at least 600 to 700 people," she said.
It takes a few minutes to do the final assembly on site but Maryl knows from experience that sweet anticipation.
"People get really excited when the cake comes down there so they don't want to take a lot of time waiting for us to get it done. There's always people taking a lot of photographs."
The locally-owned bakery has been serving up huge cake creations for Canada Day in Barrie for years, including really elaborate slabs of sweet goodness for about the past nine.
Like all Cakes By Design sweets, the birthday cake is nut free.
The cake cutting will take place at 6 p.m. downtown on Dunlop Street.
