From Mother's Day party, 2008 - a dessert I made just for the mommies. I just used whatever I had in the pantry and my DD and DIL then wanted the recipe. To the best of my feeble recollection, this is what I did. ;-)
Preheat oven to 350°F Line 48 mini muffin cups with paper liners. If you don't have mini muffin pans, bake them in a standard 9-by-13 pan and then cut them into small pieces after baking.
Dump brownie mix into a large bowl. Mix water with espresso powder and stir in along with the oil and eggs. Add the cinnamon and chips stirring until just combined. Note - I used cappucino chips since that's what I had. Semi-sweet chocolate chips would work or cinnamon chips if you can find them.
Divide the batter equally among the muffin cups. Each will be about 2/3 full. Using a cookie scoop makes this a little easier. Or transfer all the prepared batter into a 4-cup measuring cup and pour from the spout.
Bake for 12-14 minutes. (adjust baking time if using a cake pan - see box for directions). The toothpick test will be unreliable to judge done-ness since these are gooey. At 12 minutes, press lightly on the top of one - it should have some spring to it if done. Mine did take the full 14 minutes and my oven runs hot.
Remove to a rack and cool completely.
Stir the cinnamon, ginger and chocolate chunks into the frosting. Dollop a generous amount on top of each cooled brownie bite. Don't be stingy!
Sprinkle with powdered sugar. Grate a little more dark chocolate on top.
Store in the fridge and hide them from the kids. ;-).
