Fudgy chocolate and coffee brownies get topped with a fluffy whipped buttercream frosting. Add on some generous caramel swirls and it’s like your favourite coffee come to life in edible form!

For these brownies, we rely heavily on the melted butter and light brown sugar to give the fudgy texture and super shiny topping. To make the shiny top on a brownie, there are arguments as to whether it’s the egg, or the molten sugar in the butter, so let’s make sure to do both. This recipe cuts neatly into 9 pieces, but could be sliced smaller, and the recipe is easily doubled. They keep well in the fridge for a few days. That said, they don’t last long if you’ve got lots of happy hungry mouths in the house!

When it comes to making the best brownies, here are a few tips to keep in mind:

  1. Quality Ingredients: Always use high-quality ingredients in your brownie recipe. This includes using good quality chocolate, cocoa powder, and fresh eggs. It will make a noticeable difference in the taste and texture of the brownies.
  2. Don’t Overmix: When combining the ingredients, be gentle and avoid overmixing the batter. Overmixing can lead to a denser and tougher texture. Mix until the ingredients are just combined.
  3. Proper Pan Size: Use the recommended pan size mentioned in the recipe. Using a smaller or larger pan can affect the baking time and the texture of the brownies. For fudgy and moist brownies, an 8×8-inch square baking pan is usually recommended.
  4. Do Not Overbake: Keep a close eye on the brownies while they are baking and avoid overbaking them. A slightly underbaked brownie will be fudgy and moist, while an overbaked one can turn out dry. Insert a toothpick into the center – if it comes out with a few moist crumbs, the brownies are done.
  5. Let Them Cool: Allow the brownies to cool completely in the pan before cutting and serving. This helps them to set and ensures that they hold their shape. It also allows the flavors to develop fully.
  6. Experiment with Additions: Feel free to get creative with your brownie recipe by adding your favorite mix-ins such as nuts, chocolate chips, or even a dollop of peanut butter. Just make sure not to overload the batter, as it may affect the texture.

Remember, practice makes perfect when it comes to baking brownies. Don’t be afraid to make tweaks and adjustments to the recipe to suit your preferences. You can totally shift the frosting quantity for more or less, just do what suits you!

Brown Sugar Oatmilk Shaken Espresso Brownies

Ingredients Required 

There are no specialist ingredients or equipment required for this bake. I can find everything I need at my local supermarket or grocery store. Also, I use a standard 8 inch square tin for almost all of my traybake recipes for ease. If you do want to convert to 9 inch, you’ll need to play with the quantities a little or they will be too thin. To line a square baking tin, cut two pieces of baking paper that are just narrower than the width of the tin (less than 8 inches wide). Then place one on top of the other in opposite directions, so that all four edges of the tin are covered. This will make removing the bake so much easier! 

  • Dark/Semi-Sweet Chocolate, Melted
  • Unsalted Butter
  • Light Brown Soft Sugar
  • Granulated Sugar
  • Medium Free Range Egg
  • Vanilla Extract
  • Instant Coffee
  • Plain (All Purpose) Flour
  • Cocoa Powder
  • Powdered (Icing) Sugar
  • Caramel Sauce

Top Tips for the Best Brown Sugar Oatmilk Shaken Espresso Brownies

  • Melted Butter: As mentioned above, this contributes to the shiny top!
  • Melted Chocolate: Try to use a higher quality dark chocolate where possible, as this really does contribute to that final flavour.
  • Light Brown Sugar and Granulated Sugar: It is the combination of both sugars that creates the fudgy texture and rich flavour.
  • Cocoa Powder: Again, where possible try to use a higher quality make. This contributes so much to the flavour and I find some cheap ones really dull the richness! 
  • Frosting: Room temperature butter is best! Take it out the fridge while you bake the brownies to get the temperature down. This will allow it to mix really well and stops it from splitting – which is where the frosting can look and taste grainy.

For my Brown Sugar Oatmilk Shaken Espresso Brownies, I use a basic 8′ square pan (I like this one). I also recommend a good stand mixer or high speed mixer (like this one) to make the brownie mixture.

STORAGE FOR MY Brown Sugar Oatmilk Shaken Espresso Brownies

Because the frosting is made using lots of butter and cream cheese, you need to store these brownie cups in the refrigerator. Place in an airtight container before placing in the fridge. They will keep for up to 3 days this way. A cake tin is a great option if you have one. These can sit out while you serve and eat, just keep them in the fridge if they will go a while without being eaten.

Alternatively, you can freeze the brownies by themselves before they get filled with the frosting. Completely wrap as tight as you can using cling film/Saran wrap. If you have an airtight container too, place them in there before freezing. Let thaw in the fridge before making the frosting and serving!

Ingredients

For the Brownies

  • 100 g (½ cups) Dark/Semi-Sweet Chocolate Melted
  • 170 g (¾ cups) Unsalted Butter Melted
  • 2 tsp (2 tsp) Instant Coffee
  • 100 g (½ cups) Light Brown Soft Sugar
  • 100 g (½ cups) Granulated Sugar
  • 2 (2) Large Eggs
  • 80 g ( cups) All Purpose Flour
  • 30 g (6 tbsp) Cocoa Powder

For the Frosting

  • 113 g (½ cups) Unsalted Butter
  • 300 g (2 ½ cups) Powdered Sugar
  • Milk
  • Caramel Sauce

Instructions

  • Pre-heat your oven to 370℉/180℃. Line an 8" Square Pan with greaseproof paper.
  • In a small bowl, break up the dark chocolate and melt in the microwave in 20 second intervals, stirring in between to make sure it doesn't burn. Alternatively, set up a double boiler. Do this by placing a heatproof bowl over a small pot of simmering water. Add the chocolate to the heatproof bowl and stir until melted.
  • In a large mixing bowl, whisk together melted butter, instant coffee and both sugars. Add in the eggs, one at a time and mixing in between. 
  • Now, add the melted chocolate slowly and combine once again. 
  • Add the flour and cocoa powder, fold gently into the wet mixture with a rubber spatula or wooden spoon until just combined. Pour into the lined tin.
  • Bake 25 minutes until the top is shiny and it's still just a little wobbly in the middle. Let cool.

For the Frosting

  • Make the frosting: Add the butter to a large mixing bowl. Beat with a whisk on high for a minute to soften.
  • Add half the powdered sugar, whisk on high. Then add the remaining half and whisk everything on high until fluffy. Add powdered sugar/milk as required to meet your desired consistency.
  • Spread the frosting over the cooled brownies. Then use a spoon to dollop on the caramel sauce, and swirl in just slightly. Slice and serve!
