Potatoes are a baker's secret weapon. They add wonderful moisture and structure to baked goods including breads of all kinds as well as cakes. By mixing in cooked potatoes, you can eliminate some of the fat and add fiber and nutrients which make decadent cakes a little less dangerous, but the truth is, no one will know unless you tell them! —janeofmanytrade
Test Kitchen Notes
WHO: Janeofmanytrade is a pastry chef, beekeeper, and former soccer mom living in Nashville.
WHAT: Potatoes in their chocolatiest, sultriest form.
HOW: Mash a potato, melt chocolate, do the wet ingredient-dry ingredient cake shuffle, and bake. Top with a chocolate glaze.
WHY WE LOVE IT: We love how the potato adds a certain moistness that chocolate cakes can lack -- without seeming too starchy or savory. Plus, the edges of the cake that touch the bundt pan get crackly: a perfect contrast to the soft cake inside.

1 3/4 cups

In This Recipe
Preheat the oven to 350°F. Grease and flour a large bundt or tube pan and set it aside. Peel the potato and cut it into large cubes. Place the cubes in a saucepot and cover with water. Place over medium high heat, bring to a boil, and cook until the potatoes are tender. Drain the water off and using a masher or a mixer, mash the potatoes until no lumps (or very small ones) remain. Measure out 3/4 cup for the recipe. Take the remaining potatoes, season them as you desire, and eat them before they get cold.
In a large mixing bowl or the bowl of a stand mixer, place the sugar, cake flour and baking soda and with the mixer on low, allow the mixture to combine, about 1 minute. Add the potatoes, butter, melted chocolate, and vanilla and mix on low speed to combine. Raise the speed to medium and allow it to beat until fluffy, about 2 to 3 minutes.
Whisk together the eggs and the buttermilk. Slowly add the mixture to the batter. Scrape the bowl well and combine it completely. Scrape the batter into a pan and bake until a pick inserted comes out clean, about an hour. Allow the cake to cool in the pan for 20 minutes and then remove it from the pan to finish cooling on a rack.
Place the glaze ingredients in a small sauté pan over low heat. As this heats, stir it to melt the chocolate. Do not let it boil or simmer. Keep stirring until half the chocolate is melted. Remove from the heat and continue stirring to melt the remaining lumps. When the cake has completely cooled, use a piping bag or a spoon to drizzle the glaze over the top of the cake.
