In a saucepan, bring water to a boil and stir in NESCAFÉ® TASTER'S CHOICE® Instant Coffee. Add in chopped NESTLÉ ABUELITA chunks and whisk until dissolved. Remove from heat, set aside.
In a a large mixing bowl, whisk together flour, sugar, cocoa powder, cinnamon, baking soda, salt and baking powder.
Add buttermilk, butter, eggs, vanilla and (warm not hot) NESTLÉ ABUELITA mixture. Using electric mixers, beat for 3-4 minutes or until thoroughly mixed.
Pour batter into tube pan. Bake for 45-50 minutes or until toothpick inserted near center comes out clean.
Cool cake on wire rack for about 15 minutes. After 15 minutes, carefully remove cake from tube pan. Finish cooling before frosting.
FOR GANACHE:
In a saucepan, bring heavy cream to a light boil.
Add chopped NESTLÉ ABUELITA, whisk until completely melted.
Remove saucepan from heat.
Add chocolate chips to cream mixture. Let chocolate chips rest/melt for a few minutes.
Whisk until completely smooth.
Transfer ganache to a small bowl and refrigerate until creamy and thickened. I occasionally whisk it with a fork while cooling. 45 minutes - 1 hour should get you the desired consistency to frost with.
*Note* It's been recommended to use a mixer & whip ganache if you are having problems getting it to set up to desired consistency.
