1 (330ml) bottle of lager (12 ounce, beer)
1 TBS butter, melted to finish
Preheat the oven to 180*C/350*F/ gas mark 4. Butter and line a 9 X 5 inch loaf tin with parchment paper. Set aside.
Whisk the flour, garlic powder, onion powder, salt, sugar and baking powder together in a bowl to combine. Stir in the cheese and onion. Make a well in the centre and pour in the lager. Stir together with a wooden spoon to blend. Spoon into the prepared pan. Its okay for the top to look a bit craggy. ( I reserved a bit of the spring onion to sprinkle on top.)
Bake for 35 to 45 minutes, or until the sides are beginning to pull away from the pan and a toothpick inserted in the centre comes out clean. Brush the melted butter over top and let stand in the pan for 10 minutes, before tipping out onto a wire rack. Allow to cool for about 10 more minutes before slicing to serve.
Beautiful served warm with some butter for spreading. Store any leftovers in an airtight container and use within a day or so for optimum taste and texture. Any leftovers (as if!) are brilliant toasted.
