Peanut Butter Oat Cookies

Peanut butter oat cookies – a crispy outside with a soft centre, totally delicious!

Elysia whipped up these delicious cookies whilst we were self isolating during the pandemic. We had minimal ingredients in the house and it was time to get creative. With oats and peanut butter in the house, you can’t really go wrong with baking.

Oats can be used in baking, the same way you would use flour. We have used flour in addition to oats to increase the fibre of the cookie and nutrient value. The oats add a variety of texture to the cookie and using a jumbo oat aids in this greatly. For reference we use Quaker Jumbo Rolled Oats.

These cookies are delicious warm or cold and are packed with peanut butter goodness! We opted for a “not-too-sweet” cookie and the peanut butter flavour really shines through. If you would prefer a sweeter cookies, simply increase the amount of sugar in the recipe 🙂 The peanut butter we use in this recipe is a smooth 100% peanut butter variety from Tesco. However, feel free to use any peanut butter you have. A crunchy variety would also work brilliantly!

Now you have the basics, let’s get into the recipe!
