Chocolate zucchini cake – notes

My husband recently went for another run – this time it was Chudy Wawrzyniec – so as usual, I wanted to bake him a cake that would give him energy before the run. For trips, the best cakes are those that are easy to transport and won’t spoil if they’re not refrigerated.

I happened to have a lot of zucchini, so I decided to use it and bake American Zucchini Bread. I found a recipe online and got to work.

How to make chocolate zucchini cake – tips

The recipe itself is incredibly simple and requires only basic ingredients. Prepare the cake entirely without using a mixer. A spoon and a bowl are enough. I’ve prepared a short video of the preparation especially for you and added step-by-step photos. During preparation, I noticed that the batter from this recipe turned out terribly thick, and even adding moist zucchini didn’t allow me to mix the batter thoroughly. That’s why I added a little milk, and then everything combined nicely. Remember – if you have problems with overly thick batter (any kind), you can always add a little milk to it in portions!

What kind of zucchini for the cake?

Here I most recommend green zucchini – not too large, so it doesn’t have big seeds and is juicy. Cut off both ends of the zucchini and grate it with the skin on using a large-holed grater. During grating, or after standing for a while, water may form in the zucchini. Do not drain it and do not squeeze the zucchini. This cake, as I wrote above, is very dense, and this water will add moisture to it.

How many calories does zucchini cake have?

One serving of cake (when cut into 13 pieces) will have about 310 calories – and that’s the calorie count with chocolate glaze. If you want to lower the calorie count a bit, a slice without chocolate glaze will have about 260 calories. It’s up to you which version you choose, but chocolate zucchini cake tastes divine with that sweet chocolate glaze on top.

I made the glaze with milk chocolate, but you can also use dark chocolate – in that case, melt it in about 75 ml of heavy cream.

I hope this chocolate zucchini cake tastes as good to you as it did to me, my husband, and his running buddies! Be sure to let me know in the comments.

P.S. By the way, I recommend my other chocolate cake recipes – there’s a wide selection, so everyone is sure to find something for themselves. You can also buy my e-book “Beata’s Chocolate Bakes” where you’ll find delicious chocolate sweets not available on the blog!
