A few weeks ago, I made Chocolate Zucchini Bread and it was an instant hit in my home. My fiancé, Matty, cannot resist anything chocolate. I swear I’ve never met a guy who loves desserts as much as he does….

I always have zucchini on hand because I love to make zoodles. Matty isn’t a fan unfortunately so instead I made him this luscious Chocolate Zucchini Cake. I didn’t tell him it had zucchini in it at first. It was after a few bites that I mentioned it and he didn’t seem to care at all. All he tasted was the chocolate!

I didn’t have buttermilk so I used the old trick to add lemon juice to regular milk to let it go sour. Works in a pinch when you can’t find ingredients!

    We’ve been debating growing a garden in the yard this year. I’ve never had one before, but I remember my mom saying they were a ton of work. She had a garden for one year when we were kids. I used to help her pick the weeds from the garden and got so excited to see the veggies we grew. I didn’t eat them though being the veggie hatin’ kid that I was. 

    Not now though. I love my veggies!
