Easy Grapefruit Glaze
A sweet, lightly pink grapefruit glaze that is so lovely on loaf cakes, regular cakes, cookies, and anywhere else you need a little flavor boost!
I love simple little recipes that are so much more than the sum of their parts! Who would have thought that a basic mix of fresh juice and sifted powdered sugar would combine to make such an easy and versatile grapefruit glaze?
Add a punch of fresh flavor by draping this glaze to oat flour scones, gluten free molasses cookies, and oat flour sugar cookies. Or, turn a gluten free yogurt lemon cake into a grapefruit version!
I detail how to make this quick and easy recipe below, and share tips on how to adjust consistency, etc. See my lemon glaze or sweet orange glaze recipes for a similar vibe!

The Easiest Grapefruit Glaze Recipe
I love mixing grapefruit into sweet bakes to temper the inherent tartness of the fruit. Try it
- Simple ingredients. That's right - all you need are powdered sugar and a few tablespoons of grapefrui juice!
- So adaptable. Getting the proportions right for simple recipes like glazes is imperative! Once you master this formula, you can use it with other flavors and citrus juices. Experiment!

Ingredients Needed for Grapefuit Glaze
Just 2 ingredients go into this little glaze. Make sure to scroll down to my recipe card at the bottom of this post for the full ingredient amounts and instructions!
- Powdered sugar
- Grapefruit juice - I prefer the juice of a fresh grapefruit here. Choose a ripe grapefuit for the best flavor!
Variations On Grapefuit Glaze
- Lime - I love using this method for an easy lime glaze. Just swap an equal amount of fresh lime juice for the grapefruit juice.
- Add zest - For even more flavor, zest the grapefruit using a fine grater or zester into the glaze.
- Vanilla - Add ¼ teaspoon of pure vanilla extract to the glaze.
- Honey - Swap 1 tablespoon of the juice for honey to make a honey-grapefruit glaze.
How to Make Grapefruit Glaze
Here's an overview in photos of how to make this simple glaze:
1. Combine: Place the grapefuit juice and powdered sugar in a bowl.
2. Whisk: Whisk and stir together until very smooth.
Tips for the Best Grapefruit Glaze
- Adjust the consistency. You can add more powdered sugar to make a thick, frosting-like glaze or add more juice for more of a drizzly icing. Make sure to have extra sugar and juice on hand so you can adjust as needed.
- Add to cooled baked items only. The quickest way to make a glaze disappear is to add it to still-warm baked goods! Make sure to completely cool your cakes, cookies, muffins, etc., before adding the glaze so that it actually shows up on top.
- Sift the sugar. ALWAYS sift powdered sugar before whisking it into glazes or mixing it into frostings. This will eliminate any lumps and create a gorgeously smooth glaze.
- Double up. Easily double or even triple the quantities in the recipe card to make more glaze.
How to Use a Grapefruit Glaze
- Cake - Drape orange glaze over a gluten free grapefruit olive oil cake, a gluten free gingbread snacking cake, a gluten free busy day cake, or a gluten free vanilla buttermilk cake.
- Muffins - Gluten free gingerbread muffins love a glaze, as do gf blueberry muffins and oat flour blueberry muffins..
- Scones - Try this glaze on gluten free blueberry scones or try my oat flour scones recipe.
- Cookies - Dress up gluten free shortbread or oat flour shortbread with this pretty glaze!
Proper Storage
Place the glaze in an airtight container such as a glass jar with a tight-fitting lid and store it in the fridge for up to 1 week.
