These coffee-infused Espresso Brownies are fudgy, chocolatey, and topped with luscious coffee buttercream. Put your feet up and enjoy them with a cuppa for the perfect afternoon treat.

Elevate your brownie game with these Espresso Brownies! They are super easy to make and are delightful for an afternoon treat. The brownies are wickedly rich with a hint of coffee, and the swirls of coffee buttercream are sprinkled with sea salt.
There are many variations of Brownies, like Peanut Butter Brownies and Brownie Blondies, but these are my favourite. The coffee is not overpowering and goes well with the chocolate, like a mocha.

Recipe Ingredients

Note: I forgot the eggs in the above photo! The full ingredients and quantities are shown in the recipe card below.
- Dark chocolate baking chips - found in the baking aisle at the supermarket.
- Unsalted butter - unsalted butter gives you complete control of the overall flavour of your recipe, as the salt content in different butter brands can vary greatly.
- Instant coffee granules - mixed with boiling water. You could use espresso as a substitute.
- Caster sugar - also known as superfine sugar.
- Eggs - use large eggs at room temperature.
- Plain flour - also known as all-purpose flour.
- Cocoa powder - use good-quality cocoa powder. Either Dutch-processed for a deep, smooth flavour or unsweetened cocoa powder if that’s what you have available.
- Icing sugar - also known as confectioners sugar.
How to Make Espresso Brownies
Note: This is a summary of the instructions. The full ingredients and instructions are shown in the recipe card below.
For the Brownies

- Place the chocolate chips and butter in a large microwave-safe mixing bowl.

- Microwave in 30-second bursts until melted. Stir the mixture until smooth. (This took about 2.5 minutes in my microwave).

- Stir in the coffee flavouring, then add the sugar and eggs.

- Mix well until combined.

- Add the flour and cocoa powder.

- Stir to combine.

- Pour the batter into the tin.

- Bake for 35-40 minutes. Let it cool completely on a wire rack before icing.
For the Coffee Flavoured Buttercream

- Whisk the butter until smooth, then gradually add the icing sugar. Gradually adding it prevents it from flying everywhere.

- Add the coffee flavouring, 1 teaspoon at a time, and mix well until incorporated. Spread over the cooled brownie and sprinkle with sea salt.
Top Tip
Leave the brownie to cool completely before adding the buttercream; otherwise, the buttercream will melt.

Recipe Variations
- Nutty - add 50g of chopped walnuts.
- More chocolatey - add 50g of chocolate chips.
Storage
Store the Espresso Brownies in an airtight container in the fridge for up to 5 days.
To freeze, wrap each square individually with cling film or foil (without the buttercream) and store in an airtight container for up to 3 months.
Common Questions
Yes, but upon testing this recipe, I found that instant coffee granules gave the espresso brownies a bolder flavour.
If you like your brownies fudgy in the middle, they should take approximately 35-40 minutes to cook. If you cook them for too long, they will become dry and cake-like.
