In a bowl, mix the eggs, powdered coffee, vanilla, and sugar. Set aside the wet mixture.

In another bowl, mix the flour, baking powder, and salt. Set aside the dry mixture.

In a pan, melt the butter, chocolate, and unsweetened chocolate.

Once the chocolate mixture cools down, add the wet and dry mixture.

Mix half of the chocolate chips and cashews into the mixture.

Pour the mixture into baking pan and sprinkle the remaining chocolate chips.

Bake for 15 minutes or until cooked in a 170 C or 338 F oven. To check if the brownies are cooked, insert a toothpick into the center and if it comes out clean then the brownies are ready.

After baking the brownies, let cool, cut into squares, and enjoy your brownies.
