Quick and Easy Biscuit Recipe: Mary Berry Oat Biscuits

You can't beat a soft crunchy biscuit with a nice cuppa, can you? So I'm sharing this very simple Mary Berry Oat Biscuit Recipe with you to celebrate National Biscuit Day on 29th May. I love Mary Berry's biscuits and her recipes as they are so easy to follow and perfect for amateur bakers like me. Let me know what you think!

Mary Berry Oat Biscuits

I usually end up making Mary Berry Fork Biscuits. But I looked around for something new to share with you this time. I don't know about you but I don't want to spend hours in the kitchen baking. I want something with 3 or 4 ingredients that can be mixed, baked and devoured in less than an hour! These Oat Biscuits ticked all the boxes. 


  • 50g caster sugar
  • 100g of butter (softened)
  • 100g porridge oats (rolled oats work better than jumbo oats)
  • 50g plain flour

Makes about 16-18 biscuits


  1. Pre-heat the oven to 160°C. Lightly grease 2 baking trays.
  2. In a mixing bowl, cream together the softened butter and caster sugar.
  3. Add in the porridge oats and plain flour. Gently fold everything together. Don't overdo it!
  4. Lightly dust a clean surface or worktop saver with flour to prevent sticking. 
  5. Place the dough on top and gently knead until smooth.
  6. Use a rolling pin (or empty glass bottle) and roll out the dough to about 5mm thick. 
  7. If you don't have a biscuit cutter, use a mug and carefully cut out your biscuits, or roll the dough into a small ball and flatten with a fork (this is Mary Berry's technique with her Fork Biscuit Recipe)
  8. Place the biscuits onto the baking trays leaving a bit of space between each one. 
  9. Pop tray into the oven for about 20 minutes or until the edges start to turn golden brown.
  10. Once golden, remove from oven and transfer to a wire rack to cool completely.
  11. Try to resist the urge to eat them at this point.
  12. Make your favourite cuppa, grab your favourite serving plate, dish or tray and dish up your delicious batch of Mary Berry Oat Biscuits.
