* **Easy to Make:** Despite their sophisticated flavor, these cupcakes are surprisingly simple to make. The recipe uses common ingredients and straightforward techniques.
* **Perfect for Any Occasion:** While they’re especially festive for St. Patrick’s Day, these cupcakes are delicious any time of year. They’re perfect for birthdays, parties, or just a special treat.
* **That Guinness Cream Cheese Frosting!** The frosting is just the right blend of sweet, tangy, and stouty-delicious. You’ll want to lick the bowl clean!

## Ingredients You’ll Need

### For the Guinness Cupcakes:

* **Guinness Stout:** The star of the show! Use a bottle or can of Guinness Draught. Avoid Guinness Extra Stout as it is too bitter.
* **All-Purpose Flour:** Provides the structure for the cupcakes.
* **Unsweetened Cocoa Powder:** Adds a rich chocolate flavor.
* **Baking Soda:** Helps the cupcakes rise and gives them a light, airy texture. The Guinness will react with the baking soda, so don’t skip this!
* **Baking Powder:** Provides additional lift.
* **Salt:** Enhances the other flavors.
* **Granulated Sugar:** Sweetens the cupcakes.
* **Brown Sugar:** Adds moisture and a caramel-like flavor.
* **Vegetable Oil:** Keeps the cupcakes moist.
* **Eggs:** Bind the ingredients together and add richness.
* **Vanilla Extract:** Enhances the other flavors.
* **Sour Cream:** Adds moisture and tanginess.
* **Hot Coffee:** Enhances the chocolate flavor and helps to bloom the cocoa powder.

### For the Guinness Cream Cheese Frosting:

* **Cream Cheese:** Make sure it’s softened to room temperature for a smooth frosting.
* **Unsalted Butter:** Also softened to room temperature.
* **Powdered Sugar:** Sweetens and thickens the frosting.
* **Guinness Stout:** Reduced to concentrate the flavor.
* **Vanilla Extract:** Enhances the other flavors.

## Equipment You’ll Need

* **Muffin Tin:** A standard 12-cup muffin tin.
* **Cupcake Liners:** Paper or silicone liners to prevent the cupcakes from sticking.
* **Mixing Bowls:** For mixing the dry and wet ingredients.
* **Electric Mixer:** A stand mixer or hand mixer makes frosting easier.
* **Whisk:** For combining dry ingredients.
* **Rubber Spatula:** For scraping down the sides of the bowl.
* **Measuring Cups and Spoons:** For accurate measuring.
* **Saucepan:** For reducing the Guinness for the frosting.
* **Piping Bag and Tip (Optional):** For decorating the cupcakes.

## Step-by-Step Instructions

### Part 1: Making the Guinness Cupcakes

1. **Preheat and Prep:** Preheat your oven to 350°F (175°C). Line a 12-cup muffin tin with cupcake liners.
2. **Combine Dry Ingredients:** In a large bowl, whisk together the flour, cocoa powder, baking soda, baking powder, and salt.
3. **Combine Wet Ingredients:** In a separate bowl, whisk together the granulated sugar, brown sugar, vegetable oil, eggs, vanilla extract, and sour cream.
4. **Add Guinness and Coffee:** Gradually whisk in the Guinness stout and hot coffee until well combined. The mixture might bubble slightly, that’s normal.
5. **Combine Wet and Dry:** Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix. A few lumps are okay.
6. **Fill Cupcake Liners:** Fill each cupcake liner about 2/3 full.
7. **Bake:** Bake for 18-22 minutes, or until a toothpick inserted into the center comes out clean.
8. **Cool:** Let the cupcakes cool in the muffin tin for a few minutes before transferring them to a wire rack to cool completely.

### Part 2: Making the Guinness Cream Cheese Frosting

1. **Reduce Guinness:** In a small saucepan, bring the Guinness stout to a simmer over medium heat. Cook for 15-20 minutes, or until reduced to about 1/4 cup. Let it cool completely. This intensifies the Guinness flavor and prevents the frosting from being too thin.
2. **Cream Butter and Cream Cheese:** In a large bowl, beat the softened cream cheese and butter together until smooth and creamy. Use an electric mixer for the best results.
3. **Add Powdered Sugar:** Gradually add the powdered sugar, beating on low speed until combined. Be careful not to add too much powdered sugar at once, or the frosting will be too dry.
4. **Add Reduced Guinness and Vanilla:** Add the cooled reduced Guinness and vanilla extract to the frosting and beat until smooth and creamy. Taste and adjust the sweetness or Guinness flavor as needed.
5. **Frost the Cupcakes:** Once the cupcakes are completely cool, frost them with the Guinness cream cheese frosting. You can use a knife, spatula, or piping bag to frost the cupcakes.

## Tips for Perfect Guinness Cupcakes

* **Use Room Temperature Ingredients:** Softened butter and cream cheese incorporate more easily and create a smoother frosting. Room temperature eggs also help create a better emulsion in the cupcake batter.
* **Don’t Overmix the Batter:** Overmixing develops the gluten in the flour, which can result in tough cupcakes. Mix the wet and dry ingredients until just combined. A few lumps are okay.
* **Use a Light-Colored Baking Pan:** Dark baking pans can cause the cupcakes to brown too quickly on the bottom.
* **Cool Completely Before Frosting:** Frosting warm cupcakes will cause the frosting to melt and slide off.
* **Reduce the Guinness Properly:** Reducing the Guinness concentrates its flavor and prevents the frosting from being too thin. Be sure to let it cool completely before adding it to the frosting.
* **Adjust the Sweetness:** Taste the frosting and adjust the amount of powdered sugar to your liking.
* **Get Creative with Decorations:** Top the cupcakes with green sprinkles, chocolate shavings, or even a shamrock candy for a festive touch.
* **Use Fresh Guinness:** Stale Guinness will not provide the best flavor. Buy a fresh can or bottle specifically for this recipe.
* **Blooming the Cocoa:** Blooming the cocoa powder in hot coffee (or hot water) unlocks more flavor. This is a key step for a rich, decadent cupcake.
* **Weigh your ingredients:** For best results, use a kitchen scale to measure your ingredients, especially flour. This ensures accuracy and consistency.
* **Proper storage of baked goods:** Store in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week.

## Variations and Substitutions

* **Chocolate Chips:** Add chocolate chips to the cupcake batter for an extra chocolatey treat.
* **Irish Cream Liqueur:** Add a splash of Irish cream liqueur to the frosting for a richer flavor.
* **Espresso Powder:** Add a teaspoon of espresso powder to the cupcake batter to enhance the chocolate flavor.
* **Gluten-Free:** Use a gluten-free flour blend to make these cupcakes gluten-free.
* **Dairy-Free:** Use dairy-free butter and cream cheese alternatives to make these cupcakes dairy-free.
* **Vegan:** Use vegan butter, cream cheese, and egg replacements to make these cupcakes vegan.
* **Baileys Irish Cream Frosting:** Substitute the reduced Guinness in the frosting with Baileys Irish Cream for a different but equally delicious flavor.
* **Chocolate Guinness Cupcakes:** For an even more intense chocolate flavor, add melted dark chocolate to the cupcake batter. About 2 ounces of good quality dark chocolate, melted and cooled slightly, will do the trick.
* **Guinness Ganache:** For a shiny, decadent glaze, make a Guinness ganache. Heat equal parts heavy cream and reduced Guinness until simmering, then pour over chopped dark chocolate. Let it sit for a minute, then whisk until smooth and glossy. Dip the tops of the cupcakes into the ganache or drizzle it over the frosting.
* **Salted Caramel Swirl:** Swirl salted caramel sauce into the frosting for a sweet and salty flavor combination that complements the Guinness perfectly.

## Serving Suggestions

* Serve these cupcakes with a cold glass of Guinness or a cup of Irish coffee.
* They’re the perfect dessert for St. Patrick’s Day celebrations.
* They also make a great addition to any party or gathering.
* Enjoy them as a special treat any time of year.

## Frequently Asked Questions (FAQs)

**Q: Can I make these cupcakes ahead of time?**

A: Yes, you can make the cupcakes ahead of time. Store them in an airtight container at room temperature for up to 2 days or in the refrigerator for up to 5 days. Frost them just before serving.

**Q: Can I freeze these cupcakes?**

A: Yes, you can freeze the cupcakes. Wrap them individually in plastic wrap and then place them in a freezer-safe bag or container. They can be frozen for up to 2 months. Thaw them overnight in the refrigerator before frosting.

**Q: Can I use a different type of stout?**

A: While Guinness is the traditional choice, you can experiment with other stouts. However, be aware that different stouts have different flavor profiles, so the results may vary. Avoid using stouts that are overly bitter or hoppy.

**Q: My frosting is too thin. What can I do?**

A: If your frosting is too thin, add more powdered sugar, one tablespoon at a time, until it reaches the desired consistency. Make sure the reduced Guinness is completely cooled before adding it to the frosting.

**Q: My frosting is too thick. What can I do?**

A: If your frosting is too thick, add a teaspoon of milk or cream until it reaches the desired consistency.

**Q: Can I make these cupcakes without alcohol?**

A: While the Guinness adds a unique flavor, you can substitute it with non-alcoholic stout or even strong brewed coffee. The flavor profile will be different, but the cupcakes will still be delicious.

**Q: Why is my batter so thin?**

A: The batter is naturally quite liquid due to the Guinness content. Don’t worry; this is perfectly normal and contributes to the moistness of the cupcakes.

**Q: How do I get perfectly domed cupcakes?**

A: Avoid opening the oven door while baking. Also, make sure your oven temperature is accurate. Using a slightly higher temperature (around 360°F) for the first few minutes can also help create a nice dome.

**Q: Can I use chocolate frosting instead of cream cheese frosting?**

A: Absolutely! While the Guinness cream cheese frosting is a classic pairing, you can definitely use a chocolate frosting. A dark chocolate ganache would also be delicious.

**Q: Why are my cupcakes dry?**

A: Overbaking is the most common cause of dry cupcakes. Make sure to check for doneness with a toothpick. Also, avoid overmixing the batter, as this can develop the gluten and make the cupcakes tough and dry.
