Whether you are looking for a boozy St.Patrick's Day dessert or an adult birthday cake, today's recipe is just for you. It's rich and indulgent and great for chocoholics. The beer offsets the sweetness perfectly. I also want to point out that there is no root beer in this recipe.

Key ingredients for best beer cake
- Eggs- Be sure they are large and at room temperature.
- Oil- Contributes to a moist cake.
- Guinness beer- Brings in a distinct flavor and adds moisture.
- Cake mix- You can use Devil's food cake or regular chocolate.
- Chocolate buttercream icing- A delicious classic and perfect for this cake.
- Heavy cream- Don't skimp on low fat cream.
- Chocolate chips- Best with semisweet chocolate.
Variations for chocolate stout cake
- Use alcoholic frosting- Try bailey's buttercream frosting or Irish cream frosting to really booze it up.
- Use yellow cake mix- Chocolate cake mix is the best, hands down! However, you can try a yellow cake mix, if you want the beer flavor to be really prominent.
- Replace ganache with frosting- Some people are intimidated by Chocolate Ganache but you can easily omit that and instead, just use chocolate frosting. I have shared one in the recipe card below but here are some other chocolate icing options you can try too: Chocolate Whipped Cream or Chocolate Cream Cheese Frosting or Chocolate Ganache Frosting.
- Add more layers- Double the recipe and make 4 round cakes to make a taller layer cake.
- Birthday decorations- If you are making this for birthday parties, toss some sprinkles over the cake and add some cute candles.
- Add crunch- By tossing some chopped nuts like almonds, pistachios, pecans, walnuts between the cake layers and on top, as well.
- Add fillings- Drizzle a little Homemade Caramel Sauce between the cake layers.
- Make cupcakes- Instead of cakes, pour batter in cupcake liners and bake for about 20 minutes.
How to make easy chocolate Guinness cake recipe with cake mix?

- Pour ganache- Over the top and chill again.
- Decorate- With chocolate toppings.
Tips and Techniques
- Brand of cake mixes– I have used these brands of cake mixes successfully: Pillsbury, Duncan Hines and Betty Crocker. I have not tried any other generic brands to know how it would affect this recipe.
- All ingredients should be at room temperature– That’s because they blend together smoothly and evenly.
- Temperature is key– Do not frost or ganache the cake until it has fully cooled down or else it will make a sticky, soggy mess.
- How much ganache to use? This is entirely a personal preference. Some people just like to drizzle a little all over the cake. Others, like me, pour ganache all over the cake to fully cover it.
- Decoration– Add sprinkles, chocolate chips (white or semisweet), store-bought chocolate decorations, chocolate shreds.
- Don’t over-mix cake batter– Because this will yield a tough cake and it can also cause the cake to collapse/sink during baking. Mix until all the ingredients are just combined. There may be a few lumps but you don’t have to worry about them.
- Don't over-bake cake- Or else you will get a dried out cake instead of one that is moist.
- Stout beer is best- And Guinness is very popular.
- Oil vs Butter- Normally, I prefer butter in doctored cake mix recipes but in this case, I highly recommend using oil because it prevents the cake from becoming too dense and keeps it light and airy.
Recipe FAQs
Stout beer is best and Guinness specifically is a very popular choice.
Yes, but most of the alcohol bakes out and what is leftover is so insignificant that this cake is said to be non-alcoholic.
Ginger Ale, grape juice, or coca cola would be a good non-alcoholic option. The Coca cola version would taste similar to my Coca Cola Cake (Coke Cake). You can also use other stout beers.
Storage
- Room temperature- This is best kept in the fridge but can be out for 2-3 hours.
- Refrigerate- Frosted cake can be stored in the fridge for up to 3 days in a sealed container.
- Freeze- Unfrosted cakes can be sealed tightly in plastic wrap and stored in the freezer for up to 1 month. When you are ready to assemble, allow the cakes thaw overnight in the fridge.
- Make ahead- This can be made up to 3 days a head if placed in a sealed container in the fridge. You can also keep the cake and frostings in separate sealed containers for up to 1 month. When you are ready to assemble, simply thaw and decorate per instructions below.

Instructions
- In a large mixing bowl, add eggs, oil, beer and mix until smooth.
- Add cake mix and mix and mix until just combined.
- Pour batter in two greased/ floured round cake pans (Dimensions: 8x2). Spread evenly with a spatula.
- Bake at 350 degrees F for about 30 minutes or until an inserted toothpick in the center comes out clean.
- Allow the cakes to cool down completely.
- While the cakes are baking and cooking, prepare the chocolate frosting, following the recipe above.
- Place one cake on a cake board (same size as the cake).
- Spread frosting on top of the cake.
- Place the other cake on top of the frosting and gently press it to hold it into place.
- Ice the entire cake in a thin coating of frosting. This is called a "crumb coat" just to seal the crumbs together. Chill in the fridge for 20 minutes.
- While the frosted cake is chilling, prepare the thick ganache by adding equal parts of heavy cream and chocolate chips in a microwave-safe bowl. Heat in the microwave at 30 second increments, mixing often, until smooth and creamy.
- Place a cooling rack on a cookie tray. Place the cake on top of the rack. Don't remove its base board.
- Pour ganache on top of the cake and spread it all around the top and let it drip along the sides. Use a spatula to cover it entirely in a ganache coating.
- When ganache is no longer dripping at the bottom, remove it from the rack and place it on a cake stand or serving plate.
- Chill in the fridge for 30 minutes.
- Decorate with chocolate rolls and sprinkle chocolate curls around the base of the cake. Enjoy!
Notes
- Use room temperature ingredients so that the ingredients blend together smoothly.
- Don't decorate a warm cake.
- Don't over-bake cake because it will dry it out.
- Omit the cake mix box ingredients and instructions and follow this recipe card instead.
- Don't replace oil with butter because that made the cake too dense.
- Leftovers can be stored in a sealed container in the fridge for up to 3 days.
- Read additional tips and variations above.

I made this as a layer cake for the past two
St. Patrick’s Day. Sooooo delicious. I used a Bailey’s Irish Cream-laced butter frosting. Yum!
I want to make it again this year but was wondering if you’ve had any experience making it in a 9 x 13” pan? Would I go by the cake mix directions for oven temperature and baking time?
Thanks for your input
Debbie

Hi Debbie, The baking temperature will be the same but the baking time can go up to about 40 minutes. Keep an eye on it after 30 minutes and do the toothpick test to ensure it's baked through.

Thanks so much! I appreciate your speedy reply

I made this in a 9x13 and used chia seeds as egg replacement. I added 1/4 cup all purpose flour to give it more structure because the chia seeds make it more loose but they give it a very rich flavor along with the Guiness. It is so very rich and moist. The 9x13 pan took about 35 minutes but every oven is different, just keep checking it. I highly recommend this recipe .
