Preheat the oven to 350°F and grease your mini Bundt pans well.
Prepare the cake batter according to the mix directions, using the eggs, oil, and milk, then stir in the almond extract and white chocolate chips.
Fill each mini Bundt cavity about three-quarters full and bake for 18 to 22 minutes, or until the tops spring back lightly when touched. Let the cakes cool completely before glazing.
Whisk together powdered sugar, champagne, and vanilla until smooth and pourable. Drizzle over the cooled cakes.
Finish with a dusting of gold shimmer and top with gold “2025” flags, sparkler picks, or any festive New Year’s toppers.
