Some of the most buttery treats are also the densest, such as lead toast, petrified fruitcake, and pan-fried black holes. Harness the power of butter with today’s Groupon: for $8, you get a dozen buttery shortbread cookies (a $17 value, HST included) from Mary Macleod’s Shortbread, located on Queen Street East.

Behind the lace-framed windows of her shop’s old-timey storefront, Scottish-born Mary Macleod hand-crafts her crumbly signature confections in small, careful batches. Perfected over the course of thirty years, her secret recipes blend Canadian flour, creamery butter, and, in some cases, Belgian chocolate, for an all-natural treat free from preservatives, additives, and cosmic dust. To compose their set of a dozen sweets, snack-seekers can mix and match eight original flavours—from innovations such as rolled coconut mixed with a spritz of Madagascar vanilla, to classic milk chocolate crunch dusted with icing sugar. Nestled in a beribboned, cardboard baker’s box, the cookies make a neatly packaged gift or catapult projectile.
