These healthy apple oatmeal cookies are soft and so easy to make! They are vegan, gluten free and free of sugar.
When I crave sugar and I am on a diet, I like making these simple healthy snacks which are free of sugar and flour. They are soft and moist cookies, very filling and they satisfy my sweet tooth very quickly. I especially like them warm. When these cookies are out of oven, there is a little bit crispiness coming from the oats. Later the crispiness goes and they become all soft. So if you are looking for a crunchy cookie, you should know that these cookies will be soft. Apples keep these cookies soft and moist.
There is nothing fancy about these cookies. You’ll want to make them when you are on a diet as they very are filling and easily satisfies sweet tooth. You need sweet apples to make these cookies. Especially Gala apples are very sweet. I mix grated apples with oatmeal. I add peanut butter -although its taste is not distinctive in these cookies, peanut butter gives a good consistency to these snacks. After you eat 3 small cookies, you’ll want to stop and save others for later as they are very filling. You can add a pinch of salt and lemon zest which balances the sweetness too. But these are optional.

How to Make Healthy Diet Apple Oatmeal Cookies with Step by Step Pictures
The steps are easy as mixing all the ingredients together.
First I grate 1 small lemon, it makes 1/2 teaspoon zest. Then I peel the apple and grate. I use 1 large apple. When I grate the apple, there will be some juice left. I don’t need this excess juice as the grated apples have already enough water to keep my cookies soft.
I place the grated apples, lemon zest and cinnamon in a medium mixing bowl. Then I mix them and add the peanut butter. When you add the peanut butter now, it mixes easily. Finally I add the oats and mix well with a spatula.
Then I make 9 balls out of the mixture, flatten them and place them on the baking sheet.
Finally, I bake for almost 12 minutes, until the cookies change color and become firm.
That’s all! Enjoy your healthy cookies!

I was pretty disappointed with this recipe, I wanted something healthy and tasty but got only healthy, which is great. The cookies didn’t hold together 😕because they needed more peanut butter than what the recipe asked for. Also they didn’t have much flavor besides cinnamon. My husband suggested to put some apple butter on top and they tasted better. 👌Definitely would not make this recipe again.
Hi Natalia! Thank you for your feedback. As they are diet cookies, it is important that you use Gala or sweet apples(so you don’t need any sweetener). I am just thinking if your apples were not juicy enough- maybe that’s why they didn’t hold together and affected the taste.
