'World's largest' cannabis brownie weighting 62st baked in US - and it's up for sale

The world’s largest weed brownie has been baked by a firm in the US weighing almost 62st.

The hefty confection, which measures three feet wide by three feet long is 15 inches tall and weighs a staggering 850 pounds (400 KG).

MariMed, based in Massachusetts, say it contains 20,000mg of THC: the main psychoactive compound in cannabis that produces the high sensation.

The firm unveiled the oversized treat to commemorate the launch of their Bubby’s Baked brand of brownies: a single-serving brownie containing a more manageable 5mg of THC.

Ryan Crandall, chief product officer and SVP sales for the US company said: “For many of us, homemade brownies were our first taste of cannabis-infused edibles.

Bubby’s recreates and elevates that nostalgic experience, infusing full-spectrum, craft-quality cannabis into timeless recipes, for a reliable high reminiscent of simpler times.”

The firm's website says the cake is inspired by the original cannabis-infused, homemade brownie and is made from scratch in small batches, and infused with precision-dosed, full spectrum cannabis.

It says they are "perfect for sharing high times with friends this holiday season."

The company has classic confectionery recipes – brownie, chocolate chip, and snickerdoodle.

It claims to use natural ingredients, starting with the basics: flour, butter, eggs, and sugar with no artificial flavours or preservatives.

Each brownie contains 5mg of THC in Massachusetts which complies with state regulations.

Mr Crandall added: “Bubby’s Baked fills a big hole in the edibles market that cannabis consumers crave – high-quality, delicious baked goods that stay moist and chewy.
