Oatmeal cookie sandwiches

Oatmeal cookies are so easy to make. All you need is a good recipe 😉 I lost count of how many attempts it took me to get to THE perfect oatmeal cookie recipe. You know, those recipes that work 10/10 and that never disappoint? That’s one of these! So save it and enjoy!

As always, this recipe is refined sugar-free, vegan, plant-based, dairy-free and you can make it gluten-free by using certified gluten-free oats.

This time, I wanted to make an even yummier variation of these cookies and made cookie sandwiches with them by simply adding a cashew frosting between two cookies.

Of course, you can eat them as they are, without adding the frosing (but it’s totally worth the extra effort! ;))

If you’re a cookie lover like I am, you will adore this recipe! It’s also super versatile, since you can replace the chocolate chips with seeds, dried fruits or nuts to create a new version each time!

The filling is a regular cashew vanilla cream, which I simply colored with beet powder (you won’t be able to taste it). You can also use other frosting recipes like this chocolate one to fill the cookie sandwiches.

Now that you have found THE only vegan oatmeal cookie recipe you need, what are you waiting for to turn on the oven?

I really hope you guys will give this recipe a try! Please let me know your feedback in the comments or tag me in your pictures on instagram @foodie.yuki! I love to see your creations! Haooy baking 🙂
