Preheat the oven to 180 degrees Celsius. Line a 12 hole muffin tin with muffin cases.
Start by prepping your flavour ingredients. Crumble the feta. Make sure the sweetcorn is fully drained. Finely slice the spring onions. Finely chop the jalapeños.
In a large bowl, mix together your dry ingredients.
In another bowl, whisk together the wet ingredients.
Pour the wet ingredients into the dry ingredients and mix gently until combined. Add the flavour ingredients and mix again.
Spoon the mix evenly into the muffin cases. Put in the oven and cook for 20-25 minutes, until risen and golden.
