Ingredients
mashed potatoes
1 cup (hot and unseasoned)
water
1 cup (lukewarm)
all-purpose flour
2 cups (sifted)
unsweetened Dutch-processed cocoa powder
3/4 cup (sifted)
instant coffee granules
2 teaspoons (optional)
baking soda
1/2 teaspoon (sifted)

miniature semisweet chocolate chips
1 cup (optional)
unsalted butter
2/3 cup (softened)
granulated sugar
2 cups
vanilla extract
1 teaspoon
large eggs
4
Instructions
1
Preheat your oven to 350°F (175°C). Grease and flour a 13 by 9-inch baking pan.
2
In a medium bowl, combine the hot mashed potatoes with lukewarm water. Whisk gently until smooth, being careful not to overbeat. Allow this mixture to cool to lukewarm.
3
In another bowl, sift together the all-purpose flour, cocoa powder, instant coffee (if using), baking soda, and salt. Set aside.
4
Toss the miniature semisweet chocolate chips in about 1 tablespoon of the sifted dry mixture to coat them. This prevents the chips from sinking in the batter. Set aside.
5
In a large mixing bowl, cream together the softened unsalted butter, granulated sugar, and vanilla extract. Beat on medium speed for about 2 minutes until well combined.
6
Add the eggs two at a time, mixing on low speed until fully incorporated. Increase the mixer speed to medium and beat for an additional minute.
7
Gradually add the sifted dry ingredients in three additions, alternating with the potato-water mixture in two additions, starting and ending with the dry ingredients. Mix just until blended; it’s okay if the batter looks a bit curdled.
8
Gently fold in the coated chocolate chips into the batter with a spatula until evenly distributed.
9
Pour the batter into the prepared baking pan and spread it evenly. Bake for 27 to 32 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
10
Allow the cake to cool in the pan for a few minutes before transferring to a wire rack. Just before serving, sift confectioners' sugar over the top for a lovely finishing touch!
