Recipes in This PostRuby Red Grapefruit Squares


Lately, I have been craving lemon squares. It’s hot at the start of July in California, and I really didn’t want to turn on my oven. One of the markets I occasionally go to has lemon squares, but, of course, when I really wanted them, they’re out. So, I had to make my own. When I made them back in 2011, my lemon squares were just the way I liked them, but I still didn’t want to turn on the oven.

When I went to the local store, they had some lovely ruby red grapefruits on sale, just as you walked in the door. How could I resist? I love grapefruit, and it’s beneficial to your health. As much as I enjoy grapefruit, I decided that even though it was hot, I could turn my oven on to make Ruby Red Grapefruit Squares.

Recipe: Ruby Red Grapefruit Squares

Summary: A twist on the classic Lemon Squares, these grapefruit squares are sweet, juicy and tart. Grapefruit itself has unique digestive properties, so if you like grapefruit, you’ll love these Grapefruit Squares.


  • 2 cup Flour
  • 1/2 cup Powdered sugar
  • 2 tablespoon Cornstarch
  • 1/4 teaspoon Salt
  • 3/4 cup Butter
  • 4 Egg
  • 1 1/2 cup Sugar
  • 1 teaspoon Grapefruit peel
  • 3/4 cup Grapefruit juice
  • 1/4 cup Half-and-half cream
  • 3 tablespoon Flour
  • 1 cup Powdered sugar
  • Pink Food Coloring


  1. First, preheat the oven to 350. Get a 9×12 pan and line it, bottom and sides with waxed paper or greased parchment paper. This is important!
  2. Make the crust by combining the crust ingredients in a food processor and processing until your have what looks a little like sand. Take this and press it firmly into the prepared pan.
  3. Combine the remaining ingredients into a bowl and mix them together. I do not suggest using a stand mixer because it is just too powerful. Use a regular bowl and whisk.
  4. Bake the crust for about 20 minutes or until the sides start to brown. Remove the crust from the oven and immediately pour the filling onto the hot crust. Put this back in the oven and bake uncovered until the mixture has set, about 15 minutes.
  5. Remove from the oven and let sit in the pan until cooled. Dust with powdered sugar. Don’t put it into the refrigerator unless you have already cut the squares, otherwise the crust will be difficult to cut.

Quick notes

Use ruby red, or other pink grapefruit. If you use white grapefruit, you will have to increase the amount of sugar.


You don’t have to use coloring, but it looks nicer. Use Wilton gel for best results.
