Crispy Oatmeal Cookies: A Healthy Homemade Recipe
When it comes to cookies, oatmeal varieties have always been popular. Unfortunately, the industrial versions you find on supermarket shelves are often loaded with sugar, glucose syrup, refined vegetable oils, and palm fat. They may highlight their “fiber content” in bold letters, but the truth is that they are far from healthy.
That is why making crispy oatmeal cookies at home is such a great alternative. By preparing them yourself, you control the ingredients, reduce added sugars, and avoid unnecessary fats. The result is a crunchy, satisfying snack that both adults and children can enjoy with peace of mind.
These cookies are made with just six simple ingredients: whole oats, coconut flour, erythritol, egg, vanilla essence, and a splash of vegetable milk or water. They are quick to bake, easy to store, and ideal for breakfast, an afternoon snack, or even to add to a lunchbox.
Why Avoid Industrial Oatmeal Cookies?
Packaged oatmeal cookies usually contain only about 30–40% oats. The rest of the ingredients are refined wheat flour, palm oil, sunflower oil, sugar, and various syrups. These additions make them energy-dense but poor in nutrients.
Excess consumption of these industrial snacks is linked to inflammation, overweight, and poor metabolic health. For children, regular intake of such products can increase the risk of obesity, insulin resistance, and difficulties maintaining healthy blood pressure and blood sugar levels.
This does not mean oats themselves are harmful. Oats can be a very beneficial food when consumed in moderation and in their least processed form. The problem lies in the way they are packaged and marketed in unhealthy, sugary cookies.
Crispy oatmeal cookies made with oats, coconut flour, and erythritol are a healthy alternative to industrial cookies.
Nutritional Benefits of Homemade Crispy Oatmeal Cookies
When you bake these cookies at home, the ingredients bring real nutritional value:
1. Oats
Oats are rich in soluble fiber, particularly beta-glucan, which has been linked to improved cholesterol levels and better blood sugar control. They also provide complex carbohydrates, plant-based protein, and minerals like magnesium and iron. Choosing whole oats or certified gluten-free oats makes them suitable for most diets.
2. Coconut Flour
Coconut flour is naturally gluten-free and provides additional fiber, which helps regulate digestion and prolong satiety. It also contributes a mild, pleasant flavor that complements the oats and vanilla.
3. Erythritol
Instead of sugar, this recipe uses erythritol, a natural sugar alcohol with zero calories and no impact on blood glucose. It is safe for people with diabetes and helps keep the cookies sweet without compromising health.
4. Egg
Eggs supply high-quality protein, healthy fats, and essential vitamins such as B12 and D. They also help bind the ingredients together and give the cookies structure.
5. Vanilla Essence
Although a small ingredient, vanilla essence adds a natural sweetness and aroma that makes these cookies taste comforting and indulgent.
6. Vegetable Milk or Water
A small splash of liquid helps bring the dough together. Using almond, soy, or oat milk makes the recipe flexible depending on personal preferences.
Why I Love This Recipe

- They are quick to make and require only basic ingredients.
- They are suitable for the whole family, including children.

Homemade recipes help you control ingredients and avoid hidden sugars and unhealthy fats.

Hola Noelia, jo les vaig fer en avena integral molta a casa, pot ser que la avena “xuple” més liquid i per això la masa queda bé, no sé exactament que et va poder passar. A vore si passe i ho comentem en directe ;).
Una abraçada!

Me gusta el hincapié que haces con respecto al abuso de azúcares procesados y las opciones tan sanas que das! Creo que es muy importante cuidar a los pequeños de la gran adicción que supone el azúcar. Yo soy un poco friki también de hacer las cosas yo misma y evitar al máximo todo lo conservado… Exceptuando las conservas que yo me hago al baño maría! Jaja excelente post y muy documentado!

Muchas gracias Cristina, la verdad es que la alimentación de los niños me parece fundamental, crear buenos hábitos en ellos es muy importante y hay que buscar poco a poco la manera de conseguirlo. Cocinando en casa es una buena manera de ofrecerles alimentos más nutritivos y sanos sin que por ello dejen de disfrutar como niños que son.
Saludos! 😉
