These peanut butter oat cookies are just 3 ingredients and the dough takes only five minutes to make. The cookies don’t contain any white flour, butter, eggs or refined sugar. The cookies taste like biscuit cookies and make a great snack.
I am always trying to create new oat cookie variations. Most of the ones I’ve created are soft and chewy, so I wanted something a little crunchier this time around. These cookies are not too sweet, similar to firm biscuit cookies, though they aren’t quite as hard. I especially love that these cookies are ready from start to finish in less than 20 minutes.
- Peanut Butter
- Oat Flour
- Maple Syrup
This recipe uses natural creamy peanut butter. You can also substitute with other nut butters like almond butter or cashew butter. For a nut-free version, you can try sunflower seed butter. I have only tested this with natural peanut butter (just peanuts and salt in the ingredients) so I don’t know if it will work with regular peanut butter processed with oils.
Oat flour is what firms up these cookies and makes them taste like biscuit cookies. Oat flour is usually available at the grocery store in the baking aisle. If you have a food processor or high powered blender, you can also make your own oat flour by grinding down oats until the consistency resembles flour. I do not have a substitute for oat flour for this recipe.
The maple syrup adds a little sweetness to the cookies and also helps to firm up the dough. I have not tested this recipe with other sweeteners. I only added a little maple syrup to these cookies because I prefer biscuit cookies that have only a hint of sweetness. You can add a little more syrup if you prefer sweeter cookies.
These cookies have a firm texture, similar to biscuit cookies. However because of the minimal ingredients and lack of eggs, they are a little more delicate. They do break apart more easily and are not as hard or firm as regular biscuit cookies.
