For a very simple biscuit, or cookie, you can’t get better than Orange & Lemon Oat Biscuits, or Cookies. These simple to make biscuits are great. The wonderful citrus flavour matches the crunch of the perfect biscuit. I based this recipe on one I saw on Moorlandseater. The recipe looked great and I could hardly wait to try it out.

However you can have a softer biscuit too. Simply adjust the baking time. Of course, I like biscuits in any form with a cup of tea. But these lovely citrus oat ones are top notch.

This is a very simple recipe. But it does use finely processed oats. I chopped rolled oats in a food processor to make a fine oatmeal, which made it very easy. How finely processed they are is a matter of preference. Particular favourites, of mine will always be those biscuits which are suited to dunking. These are just perfect for that.

The process is very simple for this recipe. Just process the oats finely. Then add all the other ingredients except the sultanas, mixed peel, butter and egg. Rub the butter into the dry mixture. Add in the mixed peel and sultanas. Add enough egg to bring the mixture to a dough. The dough needs to be chilled for about 45 minutes. Then it can be rolled out and cut into biscuits, ready for baking.

You can swap out the sultanas for other dried fruit or chopped nuts. Doing so make these biscuits perfect to satisfy any palate. Indeed you can also leave our the zest and use some spices instead.

As another variant you might include some finely ground desiccated coconut as well. In fact I think I will try that soon.

My Bake

I baked my biscuits for 17 minutes. They coloured well and felt slightly firm when they came out of the oven. Then, when cooled on a wire rack, they became nice and crunchy. In fact, for me, they had the perfect crunch. They were great for dunking in my tea too.

I found they were great with a nice cup of tea. Indeed I had to be very careful not to eat too many biscuits. If you are like me you may well quickly become addicted to these lovely biscuits. As I mentioned earlier, these biscuits are perfect for dunking in tea.
