This Custard Tart is as yummy as it is fun and impressive. As the tart bakes, it separates into layers: there’s a crust, a custard middle, and a cake layer at the top. So much fun!

We call this the 1-2-3 tart.
Why? Well, a few reasons… It separates into those 3 layers like I mentioned; it has easy measurements that are either 1, 2, or 3; and everyone always wants 1, 2, and 3 slices! It’s so good!

magically separates
People always ask me how I got it to separate into layers like this. I just say that it’s magic!
Really though, it separates because of the beaten egg whites; they float to the top of the tart because they’re lighter and fluffier than the custard.
I bet your kids would love to help you make this, and the older kids could make it themselves as a special treat.

I usually serve it with a simple sprinkle of powdered sugar over the top, but you could also sprinkle the tart with granulated sugar and brûlée the top to give it a crunchy sugar shell.
However you serve it, it’s the perfect comforting dessert.
And, that’s not a bad calorie count for a great dessert like this!

Custard Tart or 1-2-3 tart
Ingredients
- 8 tablespoons unsalted butter, melted and cooled plus more for pan
- 2 cups milk
- 1 cup all-purpose flour

Instructions
- Preheat oven to 350° F. Lightly butter a 9-inch deep-dish pie plate or tart dish; set aside.

This is so easy. I’ll have to try it tonight for dessert. I wonder how it will work with white whole wheat flour? I’m pinning and stumbling this recipe.

I’m a sucker for anything custard-y, and I’ve always loved the magic of desserts that mysteriously separate themselves into layers as they bake! Definitely so fun! Gorgeous pics – what a bummer that I just lodged my fork in my computer screen trying to snag a bite! 😀
