Once simmering, reduce the heat to medium or medium low and simmer until the apple cider has reduced down to a third of its original amount (leaving you with 1/2 cup of apple cider reduction)
Preheat your oven to 350 degrees
Transfer the apple cider reduction into a small dish and allow it to cool for about 10 minutes

In a separate bowl, whisk 1 large egg, 2 tablespoons of melted butter, 1/2 cup of whole milk, 2 teaspoons of vanilla extract, 1/2 cup of brown sugar and 1/2 cup of granulated sugar until fully combined
