Adapted from Bon Appetit to fit a bundt pan, this chocolate cake has a surprise: My Goodness, My Guinness. It can be topped with homemade chocolate ganache, chocolate icing, or ice cream.

    • 1 cup stout (such as Guinness)
    • 1 cup (2 sticks) unsalted butter
    • ¾ cup unsweetened cocoa powder
    • 2 cups all purpose flour
    • 2 cups sugar
    • 1 ½ teaspoons baking soda
    • ¾ teaspoon salt
    • 2 large eggs
    • ²⁄₃ cup sour cream
    • 6 ounces good semisweet chocolate chips
    • 6 tablespoons heavy cream
    • ¾ teaspoon instant coffee granules
    • 2 cups heavy whipping cream
    • 15 ounces bittersweet (not unsweetened) or semisweet chocolate, chopped

Preheat oven to 350 F. Butter or spray a bundt pan well, making sure you grease all the creases. Bring the stout and butter to a simmer in heavy large saucepan over medium heat. Add cocoa powder and whisk until mixture is smooth. Cool slightly. Whisk the flour, sugar, baking soda, and salt together in large bowl.

Using an electric mixer, beat eggs and sour cream in another large bowl to blend. Add stout-chocolate mixture to egg mixture and beat just to combine. Add flour mixture and beat briefly on slow. Using rubber spatula, fold batter until completely combined. Pour batter into the greased bundt pan, and bake until it passes a cake test, about 35 minutes.

Transfer cake to rack and cool completely in the pan. Turn cake out onto the rack and serve either with ganache, or your favorite topping.

For the ganache (optional):
Bring cream to simmer in small saucepan. Remove from heat; add chocolate and whisk until smooth. Pour over cake, or reserve for individual servings. (Can be made one day ahead: Chill, rewarm before using.)
