Grease an 8”x8” square baking pan and line with parchment/ baking paper (with 1-2 inches overhang).
Preheat oven to 180 °C / 350 °F.
Melt butter in microwave for 2 minutes with pause every 30 minutes.
Add heated melted butter into the chocolate chips and the instant coffee. Mix until becomes smooth. Set aside to cool.
In a large mixing bowl, combine granulated sugar, dark brown sugar and eggs. Add eggs one at a time and mix to incorporate.
Add vanilla extract/ essence, salt and the chocolate mixture. Mix until well combined.
Sift all-purpose flour and cocoa powder into the chocolate batter.
Fold gently until just combined. Do not over mix.
Toss the walnuts and cashew nuts, if using and incorporate with the batter.
Transfer batter into the prepared baking pan. Tap pan few times to release air bubbles.
Bake for around 28-30minutes and check using the toothpick test. If the toothpick comes out with a little crumbs, you can take the brownies out as it will still cook from the remaining heat. Do not overbake.
Remove from the oven and let it cool completely about 2 hours before cutting into 16 squares.
Put each brownie squares into a cupcake liner and serve.
Share and enjoy!

Notes
You can reduce the sugar to 1 cup, just use ½ cup granulated sugar and ½ cup dark brown sugar. Or just 1 cup of granulated sugar.If you don’t have a microwave, you can use a stove top to melt the butter. Or you can use a double boiler to melt the butter, chocolate chips and instant coffee altogether.After coming out of the oven, the brownies are super gooey in the middle. They’ll continue to firm up as they cool.
