This pie may not be as old-fashioned as some recipes are today, but don’t let that stop you from giving it ago yourself! This twist on the traditional lemon tart uses Grape Nuts cereal and Apple Juice in place of flour for both crispy texture and subtle sweetness
Did you know that Grape-Nuts has been used for years in pie crusts? Grape-Nuts itself has been around for more than 100 years.

A Tidbit About the Name
Grape-Nuts actually contains neither grapes nor nuts. It’s made from natural wheat and barley. So, why is it called Grape-Nuts? As with many great emblems in history, there are two versions of the story.
One says that Mr. Post believed glucose, which he called “grape sugar,” formed during the baking process. This, combined with the nutty flavor of the cereal, is said to have inspired its name. Another explanation claims that the cereal got its name from its resemblance to grape seeds, or grape “nuts.”
Ingredients
This pie is really easy to make with the following ingredients:
- 1 cup Grape-Nuts Cereal
- ¼ cup frozen apple juice concentrate, thawed
- 14 ounces sweetened condensed milk
- 2 large eggs
- Juice from 3 lemons + zest from one of them
- Whipped cream for garnish

Instructions
- Preheat oven to 350 degrees. Lightly spray glass pie pan with non-stick spray and set aside.
- Place a cup of Grape-Nuts in your food processor. Pulse until it becomes fine and crumbly. Don’t worry about having some nutty bits left behind.

Add ¼ cup of thawed apple juice concentrate and pulse a few more times until the cereal is moist.

- Spread the cereal out in a lightly sprayed pie pan. Be sure to cover the entire bottom and about halfway up the sides. Now it only takes 5 minutes to bake.

- While the crust is baking, combine a can of sweetened condensed milk, 2 eggs, the zest from one lemon, and the juice from three lemons.

Pour this creamy mixture into the prebaked pie crust and bake for another 15 minutes.

- Allow the pie to cool and then refrigerate it for a couple of hours.
- Garnish with whipped cream, if desired.

Can’t find frozen apple juice? You can make your own concentrate by boiling 1 cup of apple juice over medium-high heat until it reduces to ¼ cup. Allow it to cool before using it in this recipe.

That looks like a little slice of summer 🙂 I did not know that Grape Nuts has been around for 100 years. I also didn’t know you could make a pie crust from it. Thanks for the info.

What a great pie! It kind of reminds me of a recipe I have for Key Lime Pie. I ADORE the idea of using Grape Nuts and apple juice for the crust. This means I just *might* be able to have a bigger slice. Thank you for sharing!

Great looking pie. It resembles one of my favorites, a key lime pie.
This looks like an awesome way to use Grape Nuts, yum!
Sorry I don’t know how to leave a reply or question to the original poster who gave the recipe.
I don’t eat eggs. I know there are a lot of egg substitutes but it depends on different things on which one to use. I know it can depend on the use of the egg but don’t know if there are others.
I’m hoping someone can give me advice on what egg substitute will work.
Thanks.
Unfortunately, I don’t know of a good egg substitute for this pie. Here is a recipe for a lemon tart that does not have eggs: http://www.snackworks.com/recipe/refreshing-lemon-tart-108291.aspx
