Chocolate Stout Cake with Vanilla Bean Mascarpone Frosting + 5 Stout Desserts You Should Make For St. Patty’s Day!

csc0036When you marry a Fitzpatrick and live near Boston it is necessary to celebrate St. Patty’s Day. Before we had kids, Bubba and I would head to an Irish pub and drink green beer. Before I met Bubba, I drank way to much green beer and listened to bad Irish bands at the Black Rose with my college roommate, Amy, also an Irish girl.  When I was a kid, my grandmother made corn beef and cabbage and gave us green carnations on St. Patty’s Day. I guess in some way I have always celebrated this holiday. This year with a new baby in the house, C and G to take care of, and a complete lack of energy, our celebration will be minimal. Sure I will have a beer to celebrate. I just may fall asleep shortly after I finish it. I may even attempt to make this corn beef and cabbage recipe. Maybe Bubba will help the kids make a leprechaun trap this weekend.

I am not sure how we will actually celebrate this holiday. So in anticipation of a busy weekend and not enough sleep, I made a chocolate stout cake with vanilla bean mascarpone frosting a few days early. This was my first attempt making a chocolate stout cake. I love chocolate, but I am not a huge fan of stout beer, so I was a bit hesitant to try this recipe. I am so glad I gave it a shot anyway, because it is by far one of the tastiest cakes I’ve made! The chocolate and the stout are similar in that they both add a dark, bold flavor. The sour cream keeps the cake super moist. The sweet vanilla bean mascarpone frosting adds the perfect balance of sweetness to a slightly bitter crumb. Overall, I love this cake!


The recipe suggests serving the cake with a stout beer like Guinness. Bubba tried it and said it is a great pairing. Who knew?

csc0020I chose mascarpone (Italian style cream cheese) instead of traditional cream cheese because I had a container of it in the fridge. While making the frosting, I got distracted by N’s crying and over-beat it. The butter and cream cheese separated a bit. I almost threw it out, but Bubba said it still tasted good. I went ahead and frosted the cake, and, yes, it did still taste good. Next time I make cream cheese frosting, I’ll follow these tips by Joy the Baker.

Have a great St. Patty’s Day!

Chocolate Stout Cake with Vanilla Bean Mascarpone Frosting

recipe slightly adapted from Simply Recipes

serves 6-8


1 cup stout of stout beer, like Guinness

10 tablespoons unsalted butter

3/4 cup unsweetened cocoa

2 cups superfine sugar

3/4 cup sour cream

2 eggs

1 tbsp. pure vanilla extract

2 cups all-purpose flour

2 1/2 tsp. baking soda

1/4 tsp. kosher salt


Pre-heat your oven to 350°F. Grease a 9-inch spring-form pan with butter. Line the bottom with a round of parchment paper. Set aside.

Add the beer and butter to a large sauce pan and cook over medium-high heat until the butter is completely melted. Add the cocoa powder and sugar. Whisk together until combined. Remove from heat. Allow it to cool to room temperature.

In a separate bowl beat together the sour cream, eggs, and vanilla extract until well combined. Add the sour cream mixture to the butter & beer mixture and whisk together until fully incorporated.

In a large bowl whisk together the flour, baking soda, and salt. Add the beer-butter mixture and whisk together until it just comes together. Do not over whisk!

Pour the batter into the prepared spring-form pan. Drop the pan on the countertop a few times to shake out the air bubbles in the batter .

Bake for about 50-60 minutes, but check doneness at 50 minutes. Cool completely in pan, on a wire rack. When cool, run a knife around the edge to separate the cake from the pan. Remove the ring from the pan. Carefully transfer cake to cake stand. Spread on the frosting and serve with a nice, cold stout. Happy St. Patty’s Day!
