If you’ve never heard of “invisible cake,” you’re in for a treat. It’s not actually invisible, of course, it just looks that way when you slice it. This Savory Butternut Squash Invisible Cake is made with ultra-thin layers of butternut squash suspended in a barely-there custard. It's light, elegant, and surprisingly simple to make!
Preheat oven to 375°F. Line an 8-inch loaf pan or round cake pan with parchment paper and lightly grease it.
In a large bowl, whisk together the eggs, milk, and olive oil. Add the flour, baking powder, salt, pepper, nutmeg, fresh herbs and grated Parmesan. Whisk until smooth and lump-free.
Add the thin butternut squash slices to the bowl and gently toss to coat each piece with the batter.
Pour the mixture into your prepared pan, pressing down gently to compact the layers.
Sprinkle the extra 2 tbsp Parmesan on top.
Bake for 45–55 minutes, or until golden brown on top and a knife inserted in the center comes out clean.
Let it cool for at least 15 minutes before unmolding. Slice carefully, the layers will be beautifully visible!
