Double Chocolate Cream Cheese Coffee Cake

My mother seems to like to make coffee cakes. She used to be well known for always having freshly baked muffins on hand, then often she would have banana chip cake around. She was also well known for making delicious banana loaf, blueberry coffee cake, rum cake, and oatmeal chocolate chip cookies. But lately she has been trying out many different new coffee cake recipes. It began with this one: {Cinnamon Cream Cheese Loaf Cake}. Then evolved to a chocolaty version: {Chocolate Cream Cheese Loaf Cake}. Then she tried: {Sour Cream Coffee Cake}. Which is different because it does not contain a cream cheese filling, but is made with sour cream to keep it moist and has a cinnamon streusel in the middle. Finally comes this one. This is basically the same as the previous chocolate version, but with chocolate chips added to the cream cheese filling and a few modifications to improve it. It is delicious warm or cold. And it definitely gives a good dose of chocolate. The two cinnamon coffee cakes are delicious too, but chocolate will always be my favorite flavor, especially when it comes to sweets. 

These coffee cakes all have several things in common; they are baked in an 8x8 inch square pan, they contain a dairy ingredient (either cream cheese or sour cream) to keep them moist, they have a filling, they are good warm or cold, they are not too hard to make, my mother makes them all and she did a darn god job - they are delicious.
