Chocolate Potato Cake

Potatoes…in a cake? You bet!

This chocolate bundt cake has a tender, moist crumb and is made just a little extra special with this chocolate rum glaze. It makes a simple, yet pretty presentation for special occasions but is easy enough for every day.

Chocolate Bundt Cake

Bundt cakes are one of the easiest cakes to make. It’s important that you use both shortening and flour when you grease the pan. Or  even better…use cake release. This will ensure your cake comes out of the pan perfectly every time.

Make Ahead Cake

The potato flakes and the sour cream add both moisture and flavor to this chocolate cake. Many times bundt cakes are better as they sit, and this is one of those cakes! Yes, it’s good right from the oven, but if you need to plan ahead and get some baking done in advance, this is the cake you need. Just be sure you store it in an airtight container overnight.

Chocolate Rum Glaze

The quick glaze for this cake adds sweetness and flavor. It’s a simple mixture of powdered sugar, cocoa powder, water and rum. If you use rum extract,  start with one teaspoon and add a little more if you’d like. If you are using rum, about 1 tablespoon should give you good flavor.

Drizzle the glaze over the cooled cake for a pretty look.

Tools to Make this Bundt Cake

  • Cocoa Powder: We love this raw cacao powder for baking. A guilt-free superfood.
  • Hand mixer: I don’t pull out my stand mixer for this recipe. It makes a small amount so a hand mixer works perfectly.
  • Classic Bundt Pan: A nice, heavy bundt pan is the start to any good bundt cake.
  • Bundt Cake Carrier: Store your cake in this carrier to keep it fresh and easy to transport!
