 Zucchini Brownie Mug Cake

Since so many of you babe’s love making my zucchini brownie recipe, I thought that it only seemed fitting to make a mug cake similar!

If you haven’t mixed zucchini and chocolate together- then I don’t know what rock, you have been living under but you should get on it! Most people think that the zucchini will have a strong taste- but it actually yields this delicious fudge texture that is amazing.

Plus, you get added fibre and extra veggie boost just for eating your dessert which is always an added bonus!

Microwavable Mug Cake

This recipe can be made by mixing ingredients in a oven proof mug, and then microwaved in 30 second intervals for 60 second until light and fluffy. It may depend on your oven, but mine comes out perfect at exactly 60 seconds, You may need to adjust your time accordingly

How To Make Zucchini Vegan Mug Cake in The Oven

If you don’t have a microwave – bake it in the oven! I actually prefer it oven baked as it yields a better texture!

To make your ve in the oven, simply follow the same instructions but bake it in the oven instead of microwaving it! I do it at 180 degrees celsius for 12-15 minutes until slightly under.

How Do You Make The Chocolate Zucchini Vegan Mug Cake


Oat flour: I make my own by blending oats in a high speed blender to make a flour consistency.

Baking powder: Just a little to help it rise!

Cocoa powder: for that chocolate flavor!

Granulated sweetener of choice: I used a calorie free monk fruit sweetener, but any granulated sugar could work.

Zucchini:If this ingredient really freaks you out you can omit it

Apple sauce: For that fudgy texture and added sweetenedd

Chocolate chips : Use your favourite chocolate chips of choice (vegan if desired)

Milk of choice: I used almond



Grease a microwave safe bowl or mug of choice with some oil spray. Add all ingredients above and mix well
