Grand Marnier Soufflé

In a saucepan, melt the butter, then whisk in the flour and cook over low heat for 5 minutes

Add the warm milk, whisking vigorously with a wooden spoon

Next, add the grated cheese and whisk until smooth, cooking over low heat

Remove from heat and gradually beat in the egg yolks

Stir in the orange-flavored liqueur or Grand Marnier

Cover with plastic wrap and let cool

While the mixture is cooling, whip the egg whites in a large bowl until frothy

Add the baking powder and continue whipping until stiff peaks form

Fold one half of the whipped eggs into the cooled soufflé base, then gently fold in the remaining whipped eggs

Reserve 1 cup of this batter for the top layer

To bake, place the mixture in a buttered 9x13-inch baking dish and smooth the top

Place the reserved batter on top and smooth with a knife or spatula
