Whisk together in a spacious mixing bowl:

  • Veggie Disguise Technique: Grate zucchini very finely so picky eaters won't even notice the hidden vegetable in this decadent chocolate cake.
  • Storage Savvy Tip: Store cake in an airtight container at room temperature for 3-4 days, or refrigerate for up to a week to maintain maximum moisture and freshness.

FAQs

  • Can I use whole wheat flour instead of all-purpose flour?

You can substitute up to half the all-purpose flour with whole wheat flour, but using 100% whole wheat might make the cake denser and slightly less tender.

  • Is zucchini needed if I can't taste it?

Yes, zucchini adds moisture and nutrition without strong flavor. It makes the cake incredibly soft and helps keep the cake rich and tender without affecting the chocolate taste.

  • How do I know the cake is perfectly baked?

Insert a toothpick into the center of the cake. If it comes out clean or with just a few moist crumbs, the cake is done. Avoid overbaking to maintain the cake’s moisture.

  • Can I make this cake gluten-free?

Yes, you can use a gluten-free all-purpose flour blend. Choose a blend with xanthan gum for best texture, and ensure all other ingredients are gluten-free.

Instructions

  2. Sift together the dry base components in a spacious mixing receptacle, ensuring an even distribution of flour, granulated and brown sweeteners, leavening agent, and seasoning.

Notes

  • Grate zucchini on the larger side of the grater to ensure moisture and texture without making the cake too wet.
