{ Chocolate Zucchini Sheet Cake }

This delectable cake is chocolatey, moist and satisfying. It can be made with any form of courgette (zucchini/patty pan/summer squash), and is an easy picnic or bbq pack-a-long. Don’t you just love when those savoury garden veggies incorporate into something sweet like this to add a tasty topper to a delicious meal? We sure do.

This cake is super simple to make and completely crowd pleasing, but our favourite thing about it is that it calls for the very veg that most gardeners wind up with an over abundance of– zucchini. When it comes to the summer squash family, those vigorous plants will continually produce for as long as you continually pick them— all the way up until that cold hard bite of frost comes and withers them. Our courgette crop this year happens to be slow in starting, but once it hits you can guarantee they will be shared and made into many of these delicious cakes.

Thank you to Edmonton food blogger Jessica Musslewhite of MUSHROOMS & THYME blog for serving us up this wonderful recipe. (Check out her page for more exquisite recipes and food photography.) We couldn’t be more excited to try this here at the farm kitchen. Warm cake doesn’t last long in this family! We hope you enjoy it too.
