💡 Expert Tips and Tricks
- To prep ahead of time, grate the zucchini a day or so ahead of time and keep in the fridge. If there's excess moisture, drain it before adding to the batter.
- Devil's food cake is my favorite to use for this recipe, but any kind of chocolate cake mix is fine.
- You can also use your own homemade cake mix if you prefer!
- Give the cake some extra sweetness by using vanilla Greek yogurt instead of plain.
❔ FAQs
Not at all! Zucchini has a very mild flavor that disappears into the background. It enhances texture, not taste.
No, you can leave the skin on! Some people may prefer to peel the zucchini first, but you probably won't be able to tell the difference either way.
Aside from moisture and a rich texture, sour cream also provides a unique tang that goes well with the chocolate flavor. This recipe uses Greek yogurt for the same effect, but sour cream can be substituted!
📝 Substitutions and Variations
- Use sour cream instead of Greek yogurt for an even richer texture.
- Enhance the chocolate flavor by adding some cinnamon or espresso powder.
- Double down on the chocolate taste with dark chocolate morsels instead of semi sweet. You could also use milk chocolate for a sweeter result.
- Add a chocolate ganache or simple whipped cream over the top of the cake instead of the graham cracker crumbs.
Kristin’s Kitchen Tip
Like with all cakes, be sure to do a toothpick test to ensure that the cake is fully baked before you take it out of the oven!
🥡 Storage and Reheating
Keep this cake at room temperature for 2 to 3 days in an airtight container. You can also cover tightly with some plastic wrap. You can refrigerate for up to a week, but it might dry out slightly.
If you want to store it even longer, wrap individual slices and keep in the freezer for up to 3 months. Allow the cake to come up to room temperature before serving again.
