For a unique St. Patrick's Day dessert recipe, try these Guinness Brownie Muffins. It may sound strange to put Guinness beer in a dessert, but the bitter, malty flavor complements the chocolate — and makes this a true St. Paddy's Day treat.

Test Kitchen Tip

To make sure you have enough chocolate chips for the recipe, grab two 12-oz. bags or one large bag.


Preheat oven to 350°. Line a muffin pan with liners.

For the brownies, reduce Guinness in a saucepan over medium-high heat to ½ cup, about 10 minutes; let cool to room temperature.

Melt butter and 2 cups chocolate chips in a double boiler; stir in ¼ cup reduced Guinness, then cool slightly.

Whisk eggs, sugar, and vanilla into melted chocolate mixture.

Combine flour, cocoa, espresso powder, and salt; fold into chocolate mixture just until incorporated, then stir in ¾ cup chocolate chips.

Scoop batter (about ⅓ cup) into prepared liners. Bake brownies until tops crack and a toothpick inserted into centers comes out with only a few crumbs, about 35 minutes. Turn brownies onto a rack; let cool.

For the ganache, melt chocolate chips and butter in a double boiler; stir in remaining 1/4 cup reduced Guinness.

Drizzle ganache over top of brownies.
