This pie may not be as old-fashioned as some recipes are today, but don’t let that stop you from giving it a go! 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.”
How to Make a Pie Crust with Grape-Nuts
A Grape-Nuts pie crust is about the easiest crust you’ll ever make – no rolling pin, no butter, and no chilling. The cereal gives you a crunchy, nutty base, and apple juice concentrate binds it together with a touch of natural sweetness.
A few tips for the best crust:
- Pulse the cereal fine. A few small nutty bits are fine, but the finer the crumbs, the better the crust holds together.
- Make sure every crumb is moistened. Scrape down the sides of the food processor so all the cereal gets coated with the apple juice concentrate.
- Press it firmly. Use the bottom of a measuring cup to press the crumbs into an even layer across the bottom and about halfway up the sides of the pan.
- Don’t skip the 5-minute bake. It sets the crust so it stays crunchy under the filling.
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
- ½ cup fresh lemon juice (from about 3 lemons) + zest of 1 lemon
- Whipped cream for garnish

Instructions
- Preheat oven to 350 degrees. Lightly spray a 9-inch 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.

- Meanwhile, combine condensed milk, eggs, lemon juice and zest with a whisk until well blended. Pour into prepared pie crust and bake for 15 minutes, until the filling is set around the edges and only slightly jiggly in the center.

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.

Storage and Make-Ahead Tips
- Refrigerate: Cover leftovers and keep them in the fridge for up to 3 days.
- Make ahead: This pie is perfect for making the day before. It needs a couple of hours to chill anyway, and the flavor is even better the next day.
- Freeze: Wrap the pie tightly and freeze for up to 1 month. Thaw overnight in the refrigerator. The crust softens a little after freezing, but it still tastes great.
Frequently Asked Questions
No. Grape-Nuts are made from wheat and barley, so this pie contains gluten.
You can, but fresh lemon juice gives the brightest, tangiest flavor. Plus, you’ll need a fresh lemon for the zest anyway.
Yes! Swap the lemon juice and zest for lime for a key lime-style pie in the same crunchy crust.
I haven’t found an egg substitute that works in this pie. The eggs are what help the filling set as it bakes.
Just for 5 minutes. That short bake sets the crust so it stays crunchy under the filling.

The notes say to boil 1 cup down to 1 and 1/4 cup? I’m guessing it’s 1 and 1/4 cups down to 1 cup..
Thank you for catching that error. I have corrected it to say to boil it down from 1 cup to ¼ cup. Boiling it down evaporates the water in the juice leaving a more concentrated solution.
