Easy Grapefruit Glaze

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!
• Adds unique flavor to bakes. Drizzle a classic gluten free pound cake with grapefruit glaze, or drizzle it over a gluten free rhubarb cake. You can't go wrong!

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.

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.
