🥘 Ingredients

- Cinnamon - the star ingredient in this recipe and gives these oatmeal cinnamon cookies their warm and comforting flavour. It's a popular spice in baking and known for its fragrant and slightly sweet taste.
- Butter - use unsalted butter and bring it up to room temperature before using it in the recipe.
- Sugar - caster sugar or golden caster sugar can be used in this recipe, depending on your preference. Granulated sugar could also be used.
- Golden Syrup - is a key ingredient in this recipe and gives the cookies a lovely chewy texture. If you don't have golden syrup on hand, honey or maple syrup can be used as a substitute.
- Vanilla Extract - is used to add flavour to the cookies and give them a warm and comforting aroma. You could also use vanilla bean paste.
- Self-Raising Flour - contains baking powder, which helps to leaven the cookie dough and create a tender light texture.
- Bicarbonate of Soda - for texture.
- Oats - the main ingredient in these cookies which provide a hearty and wholesome texture. Rolled porridge oats are used in this recipe to give the cookies a chunky texture.
🔪 Instructions
The recipe card with ingredient quantities and detailed instructions can be found at the bottom of the post
One: Preheat the oven to 180°C (160°C fan/350°F/Gas 4) and line two baking trays with baking paper.
Two: In a saucepan, heat the butter, sugar, and golden syrup over low to medium heat, stirring until fully melted.
Three: Add the self-raising flour, oats, bicarbonate of soda, cinnamon, and vanilla extract to the melted mixture. Stir with a wooden spoon until a dough forms.
Four: Scoop heaped teaspoons of the cookie mixture onto the baking sheets, leaving space between each. Bake for 10 minutes. Once out of the oven, gently press them down flat with a wide spatula. Allow to cool for 10 minutes before transferring to a wire rack.

Top Tips
- Leave at least 5cm of space between the cookies on the baking tray, as they will spread while baking.
- Use non-stick baking paper (parchment paper) to line your trays to prevent the cookies from sticking.
- Avoid overbaking the cookies; they should be slightly golden brown around the edges and soft in the middle. Overbaking can make them dry and hard.
🍴 Serving suggestions
Serve the cinnamon cookies as snacks with a cup of tea or glass of milk, or pack them into lunchboxes and picnic hampers for a delicious energy-boosting treat.

📖 Variations
There are many ways you could customise these oatmeal cinnamon cookies. Here are a few ideas:
- Add a handful (about 50g) of raisins, sultana's, chopped dried apricots or chocolate chips to the mixture (at the same time as the flour).
- For a chewier texture, use soft light brown sugar instead of caster sugar.
- Grate in the zest of an orange for cinnamon orange cookies.
- Replace 25g of the flour with 25g of cocoa powder for chocolate cinnamon cookies.
- Add chopped pecan nuts or walnuts to the cookie mixture for added crunch and texture.
🥡 Storage
The cookies can be kept in an airtight container for up to 3 days.
🧊 Suitable for freezing?
Allow the cookies to cool down completely before placing them into a freezer safe container and freezing for up to 3 months.

❓ FAQS
The oats provide fibre and protein, helping keep tummies nice and full until dinner time. They also provide a slow release form of energy.
Rolled oats and quick cook oats are usually interchangeable in recipes. Rolled oats will give a chunkier textured cookie but they will taste exactly the same.
After 10 minutes the cookies should be golden brown around the edge but still soft in the centre. The cookies will firm up upon cooling. Leave the cookies to cool on the baking sheet for 5-10 minutes, before using a fish slice to transfer them to a wire rack.

These cookies are so cinnamony and a great texture! I used light brown sugar. Just a tip, I noticed that the recipe says to add chocolate chips at the same time as the flour if you’re using them, but if I was adding them then I’d let the mixture cool completely so that they don’t melt.
