What I love about GF Oatmeal Whoopie Pies
These GF Oatmeal Whoopie Pies were such a hit on my social media, so I knew I had to bring the recipe here! They’re soft, chewy, and full of cozy flavour—thanks to a perfectly balanced gluten-free cookie dough made with almond flour and oats. Even better, the recipe is super simple, and you only need a handful of pantry-friendly ingredients to make it happen.
Next comes the filling: a luscious, creamy vanilla cream cheese frosting that ties everything together. To make it, just grab a mixing bowl and your hand mixer. Blend everything until the frosting turns smooth and fluffy—it only takes a few minutes! A stand mixer might work, but since the volume is small, a hand mixer is the better choice here.
Once your cookies have cooled completely, go ahead and slather on a generous layer of frosting. Don’t hold back—the more filling, the better! Then sandwich them together to create the ultimate chewy, creamy treat.
If you’re feeling creative, there’s plenty of room to experiment. For instance, try adding a splash of maple extract for a fall-inspired twist, or mix in a bit of cocoa powder for a chocolatey variation. Either way, these whoopie pies are fun to make and even more fun to eat!
What you will need to make GF Oatmeal Whoopie Pies
Here’s a list of ingredients that you will need:
- Butter – First off, unsalted butter is always recommended for baking. This way we have more control over how much salt we add.
Sugars – In addition, I love to use xylitol to make these a little healthier and you can use any 1:1 sugar-free alternative that you like. However, regular sugar always does the trick!
Egg – Furthermore, you only need 1 egg for this recipe.
Almond flour – Moreover, almond flour is my favourite gluten-free flour to bake with! It’s naturally gluten-free, grain-free and lower in carbs. I don’t recommend substituting for other gluten-free flours as the consistencies vary widely.
Oats – Lastly, I recommend using rolled, old-fashioned or large-flake oats for these cookies.
