Preheat oven to 350 degrees Fahrenheit (175 degrees Celsius).

Lightly butter or coat an 8 x 8 inch baking pan with nonstick cooking spray.

In a medium bowl, whisk together vegetable oil, eggs, vanilla extract, and instant coffee until well blended.

In a large bowl, mix together all-purpose flour, sugar, cocoa powder, baking powder, salt, ground cinnamon, ground cloves, and cayenne pepper.

Add the wet ingredients to the dry ingredients all at once and stir to combine.

Stir in the chocolate chips.

Pour the brownie batter into the prepared baking pan and spread evenly.

Bake for 25 to 30 minutes, or until a toothpick inserted into the center comes out clean.

Let the brownies cool in the pan for 10 minutes before cutting into squares.

Serve warm or at room temperature.
