Cupcakes!!! Who doesn't love cupcakes? Tasty personally sized little cakes... I don't see where you can go wrong.
For my first feat with Ruby I decided to tackle a cupcake recipe. But oh no I wouldn't want to try anything too basic would I? No, no.. I went for Guiness & Bailey's Irish Cream cupcakes. Not only are we talking about the cupcake batter here but also ganache filling & buttercream frosting. Yum yum but a little ambitious perhaps?
First off, the ingredients:

Cupcakes:
1 c. Guiness
2 sticks butter (unsalted)
3/4 c. cocoa powder (I used the dutch process kind)
2 c. flour
2 c. sugar
1.5 tsp baking soda
3/4 tsp salt
2 eggs
2/3 c. sour cream
Ganache Filling:
8 oz. bittersweet chocolate (I used dark)
2/3 heavy cream
2 tbsp butter
2 tsp Bailey's Irish Cream
Frosting:
1 stick butter (unsalted)
4 c. powdered sugar
6 tbsp Bailey's Irish Cream

I'll be honest here and admit I strayed here and there from the recipe I went from. For instance I accidentally mixed up the amounts of salt & baking soda, which turned out fine. Also I used dark chocolate instead of bittersweet... it's fait to say no harm done!
For the cupcakes first turn your oven on to 350° F.
- Line 2 muffin pans or grease them well (I only have one so just had to cook two batches)
- Heat the Guiness and butter in a pot over medium heat, then stir in the cocoa powder
- Mix flour, sugar, baking soda and salt in a bowl(mind your amounts, hah!)
- Beat the eggs and sour cream in an elextric mixer, then add the beer/butter/cocoa and beat to combine
- Slowly mix in the dry ingredients on low speed and divide the batter evenly between the cupcake liners, filling them about 2/3 to ¾ full
- Bake until a toothpick inserted in the center comes out clean, for me was about 20 minutes
- Let cool completely

While cupcakes are baking, work on the ganache.
- Put chocolate in a heatproof bowl
- Heat the cream in a small pot until just starting to boil, then pour over the chocolate
- Let sit for a minute and then stir until smooth
- Add the butter and Bailey’s and stir until combined
- Set to the side to cool.

Once cupcakes are cool, cut small cone shaped portions from the center of each cupcake. This will hold the ganache. Next, eat the cone pieces or if you are feeling nice share with others.
Now you'll want to take the cooled ganache and pipe it into the cupcake centers. If you're a professional like me you can use a plastic baggie to accomplish this. You will want the ganache to fill up the cupcake so the top surface is smooth. I had to use a butter knife to smooth out my work.
Now for the frosting.
- Add butter to the bowl of your stand mixer and beat on medium-high speed until light and fluffy (2-3 minutes)
- Turn the speed down to low and bit by bit add the powdered sugar until it is all incorporated. Scrape sides as needed
- Combile in the Bailey’s until smooth
Frost the cupcakes to your heart's desire. Once again I relyed on a good ol' plastic baggie to get the job done.

Share with friends or keep them all to yourself, I wouldn't blame you if you did :)
