Grand Marnier® Souffle

Preheat oven to 400 degrees F (200 degrees C). Brush the insides of 2 (8-ounce) ramekins with 1 tablespoon melted butter and sprinkle with 1 tablespoon sugar. Place on a baking sheet lined with aluminum foil.

Melt 1 tablespoon butter and 2 teaspoons butter in a saucepan over medium-low heat; cook and stir flour in the melted butter until golden brown and fragrant, about 2 minutes. Pour in milk and cook, stirring continuously, until smooth and thick, 3 to 4 minutes. Remove from heat and transfer to a mixing bowl.

Stir orange zest and 1 tablespoon brandy-based orange liqueur into butter mixture until combined. Add egg yolks and 1/8 teaspoon vanilla; mix until smooth.

Whisk egg whites in a large bowl until frothy. Slowly add half the 1/4 cup sugar and whisk until combined; add remaining sugar and continue to whisk until meringue is thick and holds it shape, but is not stiff.

Fold half the meringue into egg yolk mixture until combined. Gently fold in second half until well mixed. Transfer to the prepared ramekins, allowing 1/4-inch of space at the top.

Bake in the preheated oven until risen and browned, 16 minutes.
