Calling all lemon lovers! This Keto Lemon Magic Custard Cake has an ethereal texture and bright lemon flavor that will make it hard to stop at just one slice!
This Keto Lemon Magic Custard Cake (or simply Magic Cake) is my first attempt at replicating the classic magic cake, which uses a single batter that separates into three layers during baking. In a typical magic cake, you end up with a dense bottom layer, custardy middle layer, and ethereal light and spongy layer on top.
This Keto Lemon Magic Cake produced a much lighter texture than the classic, which I didn’t mind at all. In fact, the contrast between the smooth custard and slightly grainy “cake” top, was so pleasing, that it was hard to stop eating them!
Because I was losing daylight, I didn’t cool this Keto Lemon Magic Custard Cake as long as I should have before cutting it into squares, but as you can see in the photo above, they were still plenty sturdy enough to hold and eat.
I’m on the fence about whether I preferred them fully chilled or not. The top was slightly crisp that first day, which I loved, but after spending the night in the refrigerator (a requirement due to the eggs) the top had softened from the moisture and had a more cake-like texture. Not a bad thing, but I really, really loved the contrast in textures in those first couple of hours out of the oven!
Because this Keto Lemon Magic Cake is pretty fragile, you’re going to want to bake it in parchment to prevent sticking, and so that you can easily lift it out of the pan when cooled, for easier slicing and serving. The dusting of powdered erythritol is optional, but does dress the cake up a bit, so I do recommend it.
If you’ve never had magic cake before, then you’re in for a treat with this keto version, which has a unique texture that isn’t quite cake, or flan, or custard, but a delightful combination of all three.
