When you grow zucchini to win blue ribbons for size at the Alaska State Fair, the result is delicious zucchini recipes from all the huge – but not quite prize-winning – zucchinis left in the garden.  Okay, so it was only the children’s division, there was NO WAY I could outgrow those amazing farmers and their GIANT vegetables, but man, did we grow some zucchini.


The here and now of zucchini

Fast-forward a couple of decades, and here I am harvesting a bumper crop of zucchini from my own garden in Washington state with the help of my older daughter.  Not growing them for size, I harvest them much before they would win any ribbons for size these days, but those tender zucchinis certainly lend themselves to delicious recipes. One of my favorite recipes to pull out from the family recipe folder this time of year is ‘Chocolate Zucchini Bundt Cake’.


The tradition of cake – the best tradition

My sister, having a summer birthday, would often request this as her birthday cake because, and I’ll quote her, she is “a genius with impeccable taste and an unparalleled palate.” Also, she is very humble…obviously.  From the tender texture of the cake to its perfectly balanced flavor of zucchini and chocolate; this cake is perfectly suited to be a summer dessert. It has won over many a dessert AND zucchini nay-sayer as it isn’t cloyingly sweet. Also, it tastes decadent enough to be enjoyed as a special treat but light enough to snack on all day. Yes, all day, if baked goods at any hour isn’t for you, it was nice meeting you but I don’t see a future for us. It has a vegetable in it.



No more locking your doors during church just to keep people from GIVING you zucchini! Enjoy that overabundance of zucchini from your garden, or your local farmers market or grocery store for that matter. You won’t regret it!

**Mix one cup of chocolate chips and 1 Tbs coconut oil or shortening in a microwave safe bowl and heat on 30 second intervals, stirring each time until the chocolate has reached perfect drizzling consistency.
