I seize any opportunity that I can to make a delicious dessert. A get together with friends is the perfect excuse to make a treat that I wouldn’t usually have in the house. Too much temptation, right?

This mocha brownie recipe has been on my mind ever since I saw a cappuccino brownie on my friend Jessica’s blog, How Sweet It Is. I love chocolate, I love coffee, and combined, they are even better!

So with friends coming over and the perfect recipe to make, I got busy. Of course, you know me. I never follow a recipe as written. By the time I ended up, my recipe didn’t look much like Jessica’s. Sorry, friend, but that’s just the way I bake.

About these mocha brownies

True confession: I don’t often make brownies from scratch. I love a few different brands of boxed mixes. Why make them from scratch when Ghirardelli does such a good job already?

You’ll love this brownie dessert. Rich and moist brownies, enriched with espresso powder and chocolate chips. Thick, chocolate butter cream frosting, also with espresso flavoring, piled on top. Chocolate sprinkles just for fun! These brownies are so good with a scoop of vanilla bean ice cream on top! Or with a cold glass of milk. Or a cup of coffee, of course.

These mocha brownies have a pretty mild coffee flavor, so feel free to amp it up a little with more espresso powder if you want!

Verdict: Oh my, these are very very good. Very rich, but very, very good. I love to enjoy with a glass of ice cold milk.
Husband’s take: “These are better than I expected.” “I could eat the whole pan.” “I thought these would be too rich, but I can’t stop eating them.” He had lots of good things to say! I think they earn his approval. My friends like them as well.
Changes I would make: I wouldn’t make any changes. These are really good. If you prefer, make brownies from scratch using Jessica’s recipe or your favorite one. I’m perfectly fine with boxed mixes, though.
Difficulty: Easy.
