Easy 3-Ingredient Gluten-Free Peanut Flour Shortbread Cookies

These easy 3-ingredient gluten-free peanut flour shortbread cookies are the perfect simple treat.
They are buttery, crunchy, and delicious—and you won’t believe how easy they are to make!
The peanut flour gives these cookies a light, nutty flavor that is perfectly balanced by the sweetness of the sugar.
This is a treat that everyone will love, even those who don’t need to avoid gluten.
The texture is completely comparable to regular shortbread, making this recipe a fantastic win for beginners and busy bakers alike!
The Rich History & Simple Appeal of Shortbread 👑
Shortbread holds a long and storied history, dating back to 12th-century Scotland, where it became a cherished teatime treat enjoyed throughout the United Kingdom.
It is beloved globally for its buttery richness and tender, crumbly texture.
The enduring popularity of shortbread comes down to its incredible simplicity—it traditionally requires just butter, flour, and sugar.
This recipe continues that simple tradition!
By using peanut flour and keeping the ingredient count to just three, we capture the classic flavor profile while offering a modern, gluten-free, and protein-rich twist.
Why Peanut Flour is Your Gluten-Free Secret Weapon 🥜
Peanut flour is the key to this shortbread’s unique flavor and texture.
If you’re new to baking with it, here are the top benefits that make it an excellent substitute for traditional flour:
- Naturally Gluten-Free: Peanut flour is naturally safe for those with celiac disease or gluten sensitivities, making it a wonderful, easy 1:1 substitute for wheat flour in many recipes.
- Protein Power: It’s a great source of plant-based protein, turning your treat into a more nutrient-rich snack.
- Lighter & Less Fat: Unlike peanut butter, the flour is made from pressed peanuts, resulting in significantly less fat than other alternatives like almond flour.
- Delicate Flavor: It provides a light, nutty flavor that is noticeable but not as strong or overwhelming as a traditional peanut butter cookie.
Tips for Crumbly, Perfect Shortbread 🔪
Shortbread is one of the simplest cookies to master, but a few small tips will ensure your 3-ingredient dessert is perfectly buttery and crumbly every time!
- Use Softened Butter: Ensure your butter is truly softened, not melted. Creaming the softened butter and sugar properly for the full five minutes is essential for light, fluffy dough.
- Don’t Skip the Pricking: Poke holes (prick) in the dough with a fork before baking. This step is necessary to allow steam to escape while the cookie bakes, preventing it from puffing up and keeping that classic flat, dense shortbread texture.
- Cut While Warm: Shortbread becomes very fragile once completely cooled. For the cleanest lines, cut the shortbread into squares or rectangles immediately after removing it from the oven while it is still warm, but before it fully hardens.
- Cool Completely: Always let the cut cookies cool completely in the pan before attempting to lift or serve them. This prevents them from breaking apart.
