The Best Chocolate Cake

So I don't know why I have always had a horrible time finding an amazing recipe for cake so I decided to create my own, it took many many tries but I did it and oh it is amazing.  This cake is moist, chocolaty so get out the very large glass of milk because you will need it.  

Cake: 2 Layers 
1 1/2 cups all-purpose flour
1 1/2 cups granulated sugar
1 1/4 cup unsweetened cocoa powder
1 1/2 teaspoons baking soda
1 1/2 teaspoons baking powder
1 teaspoon salt
2 eggs, at room temperature*
3/4 cup buttermilk
1/2 cup canola oil
2 tablespoon Mayo
1 tablespoon vanilla extract
3/4 cup strong brewed coffee, hot
2/3 cup semi-sweet chocolate chips 
 
Chocolate Buttercream
3 sticks  butter, softened to room temperature
3 cups powdered sugar
1 cup unsweetened cocoa powder
2 teaspoons vanilla extract

2 Tablespoons Hot Coffee

2-4 Tablespoons heavy whipping cream

For the cake

 Preheat the oven to 350 degrees F. Grease 2 8-inch round cake pans. Butter all around and cover with cocoa powder

In a medium size bowl combine the flour, sugar, unsweetened cocoa powder, baking soda, baking powder and salt. Set aside.

In the bowl of a stand mixer (or use a hand held mixer) beat together the eggs, buttermilk, mayo, canola oil and vanilla until smooth.

 Add the dry ingredients to the wet ingredients with the mixer on low until there are no longer any clumps of flour. Add the hot coffee and mix until combined. Stir in the chocolate chips

Pour the batter among the 2 cake pans and bake 20 to 25 minutes, until tooth pick comes out clean. Remove and let cool five minutes and take cakes out of pans, let the cakes cool completely before frosting.

For the Frosting: 

Add the butter and powdered sugar to the bowl of a stand mixer. Beat the butter and powdered sugar together until the butter is light and fluffy.  Add the cocoa powder and vanilla and beat until there are no streaks of white. Add 4 tablespoons of the heavy cream and whip the frosting for 2-4 minutes or until light and fluffy. If desired add the remaining tablespoon of the heavy cream and whip until combined. Add more powdered sugar if you would like it thicker.
