I made homemade granola (US) / oat crunchy cereal (UK) today. I have a large bag of muesli and lots of sunflower seeds so this was a good way to put them to use.

3 US cups muesli (or plain porridge oats)
1 US cup sunflower seeds (or almonds)
6 Tbsp sunflower oil (or other neutral tasting oil)
6 Tbsp runny honey (or maple syrup)
1 heaped tsp ground cinnamon (or preferred pudding spice)

Add the honey and oil to a large heavy bottomed pan and heat gently.
Stir in all the other ingredients and coat them thoroughly in the syrup.
Spread the mix out over a greased baking tray.
Bake at about 170C for ten minutes. Remove tray and stir, turning the browned bits over.
Return for another ten minutes. Turn again. Return to oven for a final five to ten minutes.
Take out of oven and stir about, then leave to cool.
Crumble gently into smallish clusters and store in an airtight jar.

For those who are interested, honey isn't a vegan ingredient because it comes from teeny tiny animals. Not all vegans take their efforts to avoid animal products down to the insect level though, so vegans who eat honey are named 'Beegans'. Quite cute!

I eat my crunchy cereal with soya milk usually as it has more protein and is cheap as chips. But if your shop stocks it, oat milk makes the perfect plant milk to eat with cereal in my opinion. Oat milk is creamy and slightly sweet, though naturally so, and of course slightly oaty. If you can get Oatly oat milk, do try the chocolate one. It's really good and probably gorgeous on granola too.
