baking for fun: St. Patrick's day mint chocolate-chip cake

For St.Patrick's day I decided to make a mint chocolate-chip cake. I really liked the images on the website I found the cake on because when the cake isn't cut, I looks like a chocolate dream. But the inside... Is a bright and vibrant green. Here's the recipe:
1 recipe white layer cake (use whatever you want)
2 1/2 cups chocolate chips
1 1/2 tsp mint extract 
Green food coloring 
20 tbsp (2 1/2 sticks) butter, cut into pieces and sofened 
8 oz bittersweet chocolate, melted and cooled
1 tsp vanilla extract
1/8 tsp salt
2 cups icing sugar

Everything after the food coloring is for the chocolate icing. You can use whatever icing you want but this chocolate icing was amazing! Anyway, this is how you make it. Make your white cake batter then add in 1 cup of chocolate chips, the mint extract, and the food coloring. Mix it up and bake it in three 8 or 9 inch pans at 350 for 20-25 minutes. I used 9 inch. Cool the cake completely (about one hour). For the icing beat all the ingredients other than the icing sugar on medium-high speed until the ingredients are combined. Reduce the speed to medium-low and gradually add the icing sugar. Beat the icing on high speed until it's light and fluffy (3-5 minutes). Ice the cake with about 3/4 of a cup of icing between each layer. Use the remaining chocolate-chips to press onto the cake. And you're done!

See you next time internet! Love, Alexa :)
