Copycat Starbucks Double Chocolate Brownies

Recently, I was waiting in a long Starbucks line, peering into their bakery case, studying it actually, to see what I could remake at home. Remaking restaurant recipes and coming up with homemade copycat versions is what I do for fun.

‘Fun’ may not be the right word, but after 8+ years blogging about food, self-imposed challenges like this inspire me. In fact, my copycat Starbucks Lemon Loaf is one of the most popular recipes on my site.

I personally have been partial to this brownie recipe I created in 2014. I’ve remade it umpteen times, but it relies solely on melted chocolate.

However, when I was reading the Starbucks site it says their brownies are made exclusively of cocoa powder, which is a twist I wasn’t expecting. So I turned to a brownie recipe I made in 2013, courtesy of Alice Medrich, doctored it up, and voila we have copycat Starbucks Double Chocolate Brownies. My family raved about these.

They’re rich, fudgy, not cakey, perfectly chewy, and so easy to make. One bowl, no mixer, and studded with chocolate chunks.

You can save yourself the $2.45 per brownie and when it’s homemade the calories don’t count either.

What’s in These Double Chocolate Brownies? 

These cocoa powder brownies require very few ingredients. Here’s what you’ll need to make copycat Starbucks brownies: 

  • Unsalted butter
  • Granulated sugar
  • Eggs
  • Vanilla extract
  • All-purpose flour
  • Unsweetened cocoa powder
  • Salt
  • Semi-sweet chocolate chunks

How to Make Chocolate Brownies

To make this brownie recipe with cocoa powder, you’ll first need to whisk together melted butter, sugar, eggs, and vanilla. Then, stir in the dry ingredients before folding in the chocolate chunks. 

Turn the batter into a greased 8×8-inch baking dish that’s been lined with foil. Sprinkle more chocolate chunks on top, then bake the double chocolate brownies until the edges are set and a toothpick inserted in the center comes out clean or with a few moist crumbs, but no batter.

These chocolate chip brownies will need to cool for 2 hours before you can slice and serve them. Trust me, the wait is worth it! 

Can I Double This Recipe? 

Yes, you can double the ingredients for these copycat Starbucks chocolate brownies and bake them in a 9×13-inch pan. 

Can I Make These Gluten-Free?

I haven’t tried it myself, but if you have a gluten-free flour blend that you trust, I say go ahead and try it in this chocolate brownie recipe!

Tips for Making the Best Chocolate Brownies

If your cocoa powder is lumpy, you may want to sift it before adding it to the brownie batter. You don’t want lumps in your chocolate brownies! 

Also, if you don’t have chocolate chunks on hand you’re welcome to use chocolate chips instead. Stick with semi-sweet though so these brownies aren’t too sweet. 

I haven’t been able to make perfectly fudgy, chewy brownies with canola oil, which is why I always use melted butter. As such, I don’t recommend subbing oil for the butter in this recipe.

Yield: 8 brownies

Starbucks Double Chocolate Brownies {Copycat Recipe}

Prep Time 5 minutes
Cook Time 25 minutes
Cooling Time 2 hours
Total Time 2 hours 30 minutes

The brownies are rich, fudgy, not cakey, perfectly chewy, and so easy to make. One bowl, no mixer, and studded with chocolate chunks!

Ingredients

  • 1/2 cup unsalted butter, melted
  • 1 cup granulated sugar
  • 2 eggs
  • 2 teaspoons vanilla extract
  • 1/2 cup all-purpose flour
  • 1/2 cup unsweetened natural cocoa powder
  • 1/4 teaspoon salt, or to taste
  • 2 cups semi-sweet chocolate chunks, divided

Instructions

    1. Preheat oven to 350F and line an 8×8-inch square baking pan with aluminum foil for easier cleanup and spray with cooking spray; set aside.
    2. To a large, microwave-safe bowl add the butter and heat on high power to melt, about 1 minute.
    3. Add the sugar, eggs, vanilla, and whisk to combine.
    4. Add the cocoa powder and stir to combine (Note – If your cocoa powder is particularly lumpy, you may wish to sift it before adding it).
    5. Add the flour, salt, and stir to combine.
    6. Add 1 1/2 cups chocolate chunks and stir to combine.
    7. Turn batter out into prepared pan (it will be thick) and smooth the top lightly with a spatula.
    8. Evenly sprinkle remaining 1/2 cup chocolate chunks on top, lightly tapping them down so they adhere.
    9. Bake for about 25 to 30 minutes or until the edges are set and a toothpick inserted in the center comes out clean or with a few moist crumbs, but no batter.
    10. Allow brownies to cool in pan on a wire rack for about 2 hours before slicing and serving. I sliced them into 8 generous rectangles similar to how Starbucks does it. Store in an airtight container at room temp or in the fridge if you like your brownies chilled.
