Irish Guinness Oatmeal Cake

Serve up a slice of leprechaun luck on St. Patrick’s Day or any special occasion with a Guinness-infused classic dessert that’s straight from the Irish countryside.

“This recipe for Guinness Oatmeal Cake is delicious and very Irish! I use regular draft Guinness for this recipe and allow it to set 4-5 minutes for the head to go down,” says popular food and travel writer Margaret Cook. For a more robust, chocolate-y flavor, try the Guinness Extra Stout.

In her latest cookbook, Flavors of Ireland (Ambassador International, $19.99), Cook recommends topping the traditional treat with premium vanilla ice cream mixed with brown soda breadcrumbs.
