Traduction d’une recette vedette au royaume-uni, voici mes fameux (ceux de ma mère, ok) carrés au sirop d’érable:

Biscuit

1/2 cup melted butter
1/4 cup brown sugar
1 cup white flour

Mix the butter with the brown sugar and flour.
Put the mixture in a buttered 9X9 cake tin and press it firmly.
Cook for 5 min.

Garnish

2/3 cup brown sugar
1 cup maple syrup
2 eggs
1/4 cup melted butter (could also be yoghurt)
2/3 walnuts
1/2 tea spoon vanilla (optionnal)
2 table spoon flour
a wee pinch of salt

oven 150°

Mix the brown sugar and the maple syrup in a saucepan. Bring it to the boil and let it cook for 5 min. Leave to cool.
