At Toast to Tech, the MIT150 finale in Killian Court on June 4, the MIT community was treated to birthday greetings recorded in space, fireworks, champagne, and a 24-foot cake that bore an uncanny resemblance to the MIT campus. Montilio’s Baking Company of Quincy used 420 pounds of sugar, 225 pounds of cake flour, and a whopping 235 pounds of shortening in its edible versions of six iconic campus buildings and Tim the Beaver astride Mass. Ave. bridge traffic, plus a 1,000-cupcake rendition of the Charles River. Together, the cake and cupcakes weighed in at more than 1,000 pounds.
