Preheat oven to 375F. Position rack in the middle of the oven.
Melt the butter. Let it cool while you prepare the other ingredients and grease the bundt pan.
Add the dry ingredients (except the chocolate chips) to a mixing bowl. Stir to combine.
Add the wet ingredients to the bowl. Mix until combined using a hand mixer. Stir in the chocolate chips. Add the batter to your mini bundt pan.
Bake for 20-25 minutes or until a toothpick comes out clean.
Meanwhile, make the glaze by whisking the glaze ingredients together.
Let the mini bundt cakes cool in the pan for at least 20 minutes, then transfer them to a cooling rack.
Once the mini bundt cakes are cool, drizzle the glaze on, and add the candied orange (optional). Store the cakes in an airtight container.
