Let’s Get Started

Step by step, we will show you how to make fudgy mocha brownies with velvety mocha frosting in just an hour.

Step One: Make the Brownies

  1. Preheat your oven to 350°F (180°C).
  2. Grease a baking dish with cooking spray.
  3. In a medium bowl, whisk together sugar, cocoa powder, instant espresso powder, cinnamon, and salt until well combined.
  4. Add soft butter to sugar mixture to make a paste.
  5. Beat in eggs, one at a time until they are well incorporated into the batter.
  6. Pour the hot water into the vanilla extract and mix them together before adding it to the batter.

  8. Pour the batter into the greased baking dish
  9. Bake for around 30-35 minutes or until a skewer comes out clean while inserting it in the center.

Substitutions and Variations

“These sinful treats are perfect for satisfying your sweet tooth cravings.”

Now, let’s talk about Substitutions and Variations. I understand that not everyone has the exact ingredients listed on hand, or may want to put their own spin on a recipe. So fear not! Here are some ideas for making this recipe your own.

If you don’t have instant espresso or instant coffee powder, you can use regular coffee grounds. However, keep in mind that the flavor may be less concentrated than with instant coffee.

For those who want a little extra spice in their life, try adding 1/2 teaspoon each of ground cardamom and ground cinnamon to the brownie batter. This will give the brownies a warm and exotic twist.

Are you a fan of café lattes? Why not transform these brownies into café latte brownies by using milk instead of water. Simply mix together 1/2 cup of milk with 1 1/2 teaspoons of instant coffee granules and add this mixture to the brownie batter along with the eggs.

For those who prefer to avoid caffeine, you can easily swap out the espresso powder for something like cocoa powder or even red velvet cake mix to create a delicious variation that’s just as tasty.

Looking for more frosting options? You could try a mocha cream cheese frosting or make a simple chocolate ganache instead of buttercream frosting. The possibilities are endless!

Lastly, if you’re feeling experimental, why not try spiking the brownies with more flavors? For example, you could add some chopped hazelnuts or white chocolate chips to the batter before baking. Or maybe even a sprinkle of sea salt to balance out all that sweetness.

No matter what substitution or variation you choose, don’t be afraid to get creative in the kitchen!

Make-Ahead, Storing and Reheating

“Warning: one bite of these Mocha Buttercream Brownies may lead to addiction.”

As much as we love these mocha buttercream brownies fresh and warm out of the oven, it is practical to store leftovers for longer enjoyment. These rich fudgy chocolate brownies spiked with espresso flavor taste even better after a day or two in the fridge. In fact, you can prepare them up to 2-3 days ahead, and they will still be deliciously moist and chewy.

To store the brownies, simply let them cool to room temperature, then wrap tightly with plastic wrap or aluminum foil. You may also transfer them into an airtight container or a resealable plastic bag. Keep them in the refrigerator for up to 4-5 days, or in the freezer for up to 2-3 months.

If you need to reheat the brownies before serving, preheat your oven to 325 F (160 C). Remove the wrapping and place the brownies on a baking tray lined with parchment paper. Bake for 8-10 minutes or until warmed through. Alternatively, you may reheat individual servings in the microwave on high power for 10-15 seconds per piece.

Keep in mind that excessive reheating may cause your mocha buttercream frosting to melt or lose its shape, so it’s best to enjoy the brownies at room temperature or chilled. They make an excellent breakfast treat with hot coffee or cafe latte, or a decadent dessert paired with vanilla ice cream or whipped cream.

Don’t forget to label your brownies with dates and names to avoid confusion in storage. If you’re planning to share your mocha brownies with friends, you can easily double the recipe and cut them into smaller bite-sized squares. They are perfect for potlucks, bake sales, birthdays, office parties or any occasions that call for something indulgent and comforting.

With these storing and reheating tips, you can definitely satisfy your cravings for mocha buttercream brownies any time of the day or night!

Tips for Perfect Results

“A match made in heaven: chocolate and coffee come together in this decadent indulgence.”

To achieve perfection in your Mocha Buttercream Brownies recipe, follow these helpful tips and tricks that I have learned through my years in the coffee industry.

Firstly, do not overmix the brownie batter. It’s crucial to mix it until everything is just combined, or else the brownies will become tough and dry. I recommend mixing the batter by hand instead of using an electric mixer to have more control over the texture of your brownies.

Secondly, ensure that you use room temperature butter when making both the brownies and frosting. The softened butter will easily combine with other ingredients, helping you achieve a smooth texture.

Thirdly, chose a good-quality cocoa powder for your brownies. High-quality cocoa powder has more chocolate solids and has had less fat removed than lower-quality cocoa, ensuring a rich flavor that harmonizes the coffee notes.

Fourthly, Do not over-bake! Brownies are best when they’re fudgy and moist, not dry and crumbly. Check for doneness by inserting a toothpick into the center of the brownies. If it comes out clean or with only a few crumbs still sticking to it, then they are ready!

Fifthly, if you want your mocha buttercream frosting to be extra fluffy, whip the butter first before adding the powdered sugar. And make sure to sift the powdered sugar; those annoying lumps can ruin your smooth creamy frosting consistency.

Lastly, let them chill in the fridge before cutting them into squares. Cooling allows your mocha buttercream to set nicely. Plus, chilled Mocha Buttercream Brownies are delightful with hot beverages like tea or cafe latte.

Follow these easy but efficient tips to guarantee scrumptious Mocha Buttercream Brownies that everyone in your family will crave!
