Preheat oven to 350°F and lightly butter a baking dish.
Cut pound cake into 1 to 1 1/2 inch cubes and spread evenly in the dish.
In a mixing bowl, whisk together eggs, heavy cream, vanilla coffee creamer, sugar, brown sugar, melted butter, vanilla extract, cinnamon, nutmeg, and salt until smooth.
Pour custard evenly over the pound cake, gently pressing the cake down so it absorbs the liquid.
Let sit for 10–15 minutes to soak.
Bake uncovered for 35–45 minutes until set in the center and lightly golden on top.
Remove from oven and rest 10 minutes before serving.
