Ingredients
- 2 cups all-purpose flour
- 1 cup granulated sugar
- 1/2 cup unsalted butter, softened
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 tablespoon instant coffee granules
- 1 teaspoon baking powder
- 1/4 teaspoon salt
- 1 cup semi-sweet chocolate chips
- 1 cup heavy cream
- 1/4 cup powdered sugar
- 1 tablespoon cocoa powder (optional, for dusting)

Step-by-Step Instructions
- Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
- In a large bowl, cream together the butter and sugar until light and fluffy. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract and instant coffee granules.
- In another bowl, whisk together the flour, baking powder, and salt. Gradually add this to the wet ingredients, mixing until just combined. Fold in the chocolate chips.
- Divide the dough in half and shape each half into a log about 12 inches long and 2 inches wide. Place the logs on the prepared baking sheet.
- Bake for 25-30 minutes, or until the logs are golden brown and firm to the touch. Remove from the oven and let cool for 10 minutes.
- Reduce the oven temperature to 300°F (150°C). Using a serrated knife, slice the logs diagonally into 1/2-inch thick slices. Place the slices cut side down on the baking sheet.
- Bake for an additional 10-15 minutes, or until the biscotti are dry and crisp. Let cool completely on a wire rack.
- For the mousse, whip the heavy cream and powdered sugar together until soft peaks form. Gently fold in the remaining coffee granules until combined.
- Spread a generous layer of mousse on each biscotti and dust with cocoa powder if desired. Serve immediately or refrigerate to set the mousse further.

Expert Tips for Success
For the best results, make sure your butter is at room temperature before you start. This ensures it creams properly with the sugar. Also, when slicing the biscotti, use a serrated knife for clean cuts. If the dough is too sticky, lightly flour your hands to shape the logs. Finally, be patient when whipping the cream for the mousse; soft peaks are key to achieving that light, airy texture.

Variations and Substitutions
If you’re looking to mix things up, try adding a teaspoon of cinnamon or nutmeg to the biscotti dough for a warm spice flavor. You can also substitute the semi-sweet chocolate chips with white chocolate or dark chocolate for a different taste profile. For a gluten-free version, use a 1:1 gluten-free baking flour.
Serving Suggestions
These decadent coffee mousse biscotti are perfect on their own, but you can serve them alongside a steaming cup of espresso or a frothy cappuccino for a true coffee shop experience. They also pair beautifully with a scoop of vanilla ice cream or a dollop of whipped cream for an indulgent dessert.

FAQs
Can I make these biscotti ahead of time?
Absolutely! The biscotti can be baked and stored in an airtight container for up to a week. Add the mousse just before serving to ensure the biscotti remain crisp.
