7 ingredients to easy One Bowl Espresso Brownie happiness!

I usually have what I need on hand for these brownies, and you probably do too! These rich and delicious brownies can be made in one bowl if you have a microwave. If you prefer you can melt the chocolate and butter over a double boiler. I like to use my own Homemade Vanilla Extract, as well.

  • Dark Chocolate, unsweetened
  • Butter, use unsalted if possible
  • Brewed Espresso or Espresso Powder
  • Vanilla Extract
  • Sugar
  • Eggs
  • All-purpose Flour
Melting chocolate
Melted Dark Chocolate

Substitutions and Additions:

You can omit the espresso if you don’t want the added caffeine or are making brownies for the kiddos. However, I think the coffee really deepens the flavor and you do not get an overwhelming coffee flavor with the finished product. You can use brewed liquid espresso or powdered espresso (see equivalency notes in recipe card).

My mom once made them with Irish Cream liqueur instead of espresso and they were absolutely amazing! Try our Homemade Irish Cream recipe.

I recommend using unsweetened chocolate, but in a pinch, I have used semi-sweet chocolate squares. You’ll find the brownies will be a bit sweeter with semi-sweet chocolate.

If you want to add nuts you’ll need about 3/4 cup of roughly chopped pecans or walnuts mixed in at the end.

Sprinkle the top of the brownie batter with chocolate chips just before baking for an added chocolate blast!

Substituting cocoa powder for solid chocolate squares:

You can substitute cocoa powder if you don’t have chocolate squares. In order to sub in cocoa powder, you must use a ratio of:

  • 3 tablespoons cocoa powder plus one tablespoon vegetable oil = 1 ounce square of unsweetened chocolate

Best baking pan – metal or glass?

I like baking brownies in a glass pan because glass cooks more evenly, without hot spots, and I prefer soft brownies. However, if you like crunchy edges use a light colored metal pan.

How do I know if my brownies are done?

These One Bowl Espresso Brownies will keep cooking after you remove them from the oven. To ensure you don’t overcook the batch the middle of the brownies should be slightly undercooked. You don’t want the middle to be raw but it should still be soft.

Tips to quickly cut brownies:

  • Make sure brownies are completely cooled before cutting
  • Line your pan with parchment paper and it will be easy to remove the whole pan without cutting
  • Always oil your pan with non-stick spray or vegetable oil
  • Always cut your brownies with an oiled serrated knife or a serrated plastic knife
