Chop your mushrooms into bite size slices and chunks - you don’t need them all to be the same size. Peel and finely chop your garlic.
Melt the butter in a saucepan over a medium heat. Add the mushrooms and cook for two minutes, then add the garlic. Cook for another three minutes, stirring often.
Add the wine and let it reduce by half. Turn down the heat to low, pour in the cream and stir. Season with salt and pepper.
Toast your bread (either in a toaster or under a grill) until just lightly toasted. Put on a plate.
Spoon the mushrooms over the bread, and pour over some of the creamy sauce. Top with the crumbled Stilton. Done!
