Step 1: Recipe & Instructions

Dark Chocolate Fudgy Brownies


  • 1 cup all-purpose flour
  • 3/4 cup cocoa powder (not dutch process)
  • 1 teaspoon instant coffee
  • 1 teaspoon baking powder
  • 1/4 teaspoon salt
  • 1 1/2 sticks (3/4 cup) butter, plus extra for greasing pan
  • 1 cup granulated white sugar
  • 2 tablespoons sour cream
  • 3 eggs
  • 2 teaspoons vanilla extract
  • 1 1/2 cups chocolate chips, divided

To make this brownie recipe you will need the following tools:

  • Stand Mixer or Hand Mixer
  • 8-Inch Square Pan
  • Rubber Spatula
  • Sifter or Fine Mesh Strainer
  • Large Bowl
  • Parchment Paper
  • Measuring Cups
  • Measuring Spoons
  • Toothpick
  • Cooling Rack or Hot Pad
  • Cutting Board
  • Knife


This is a very easy recipe to follow, but please remember to read through the entire recipe and all the directions before you get started! ;)

1. Preheat oven to 350° F. Grease an 8-inch square pan (9-inch square will work too. The brownies just won't be quite as thick.) and line it with parchment paper. Grease the parchment paper being careful not to tear it.

2. Using a sifter or a fine mesh strainer, sift together flour, cocoa, coffee, baking powder, and salt into a large bowl, making sure no lumps remain, and set aside.

3. In the bowl of a stand mixer fitted with paddle attachment (use a hand mixer if you don't have a stand mixer) cream butter and sugar on medium speed.

4. Add eggs, sour cream, and vanilla extract (while the mixer is running) and beat until the eggs are well incorporated. Stop the mixer a few times and scrap down the sides with a rubber spatula. This ensures all ingredients get mixed thoroughly.

5. Turn the mixer off and add dry ingredients. Mix again on low speed until the ingredients are well incorporated. About 30 seconds or so.

6. Add in one cup of chocolate chips. Mix just to incorporate.

7. Evenly spread the brownie batter into prepared pan and sprinkle remaining chocolate chips on top.

8. Bake for 20-25 minutes or until toothpick inserted in the center comes out slightly sticky. Testing can be tricky with any recipe that has chocolate chips baked inside. Make sure to pay attention to the toothpick to see if what's on it is melted chocolate or raw batter. Remove pan from oven and let cool on a wire rack (or hot pad).

9. Once brownies are completely cool, grab the edges of the parchment paper and lift the brownies out of the pan. Keep a firm grip on the parchment and pull the edges away from each other so the brownies don't break in the center. Transfer to a large cutting board. (You may need to run a knife around the edges where there is not parchment to free the brownies.)

10. Using a large sharp knife, cut brownies to desired size. Eat and enjoy!

I made this recipe! My wife and I loved it. The coffee gives a little mysterious taste which we really liked. Lots of chocolate too!!

wold630 (author)T50552017-07-23

Glad to hear you made them! :)

Are the chocolate chips semi-sweet, milk chocolate, or some other flavor?

wold630 (author)Quiggley2017-07-23

I used dark chocolate, but any will work!

How do you think substituting nonfat plain Greek yogurt for sour cream will come out? We always have that on hand and kids love that on tacos as a healthier substitute.

wold630 (author)djvj12017-07-11

That substitution will actually work great! Glad you asked. :)

This looks great! What can I use as a substitute for the eggs (if anything)?

wold630 (author)abhyudaya2017-07-08

You can use chia, flax, or egg replacer. For more info, check out the Eggs lesson in my Science of Baking class!
