Preheat your oven to 180°C / 356°F. Line a 20×25 cm (9x9 inch) baking pan with parchment paper. Chop your chocolate and cube the butter to make the melting process smoother.
Melt and Mix the Chocolate Base
In a heatproof bowl over a simmering water bath, melt the dark chocolate and butter together until silky smooth. Stir in the cocoa powder and instant coffee. Once combined, transfer the mixture to a larger bowl.
Incorporate Sweetness and Eggs
Gradually mix in the sugar until fully dissolved. Add the eggs one at a time, ensuring each is fully incorporated before adding the next.
Combine Dry Ingredients and Liquid Magic
In a separate bowl, whisk the flour and sea salt. Slowly fold this dry mixture into the chocolate base. Add the brewed espresso and dry red wine, stirring until you have a glossy, smooth batter.
Add the Crunch
Stir in the chopped peanuts or any preferred nuts.
Bake to Perfection
Pour the batter into your prepared baking pan and spread it evenly. Bake in the oven’s middle section for about 40 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
Cool and Serve
Let the brownies cool completely in the pan before removing them. Once cooled, cut them into squares and dust with icing sugar for a beautiful finish.
