Preheat the oven to 350°F and grease two 8-inch round cake pans.
In a mixing bowl, whisk together flour, baking powder, baking soda, and salt.
Beat butter and sugar together in a large bowl until light and fluffy.
Add eggs one at a time, mixing well after each addition.
Gradually mix in brewed coffee and vanilla extract.
Add the dry ingredients to the wet ingredients, mixing until combined.
Pour batter evenly into the prepared pans and bake for 30-35 minutes.
Let the cakes cool in the pans for 10 minutes, then transfer to a cooling rack.
For the coffee cream, whip together heavy cream, sugar, and instant coffee until stiff peaks form.
For the ganache, heat the cream in a double boiler, then add chocolate chips and butter.
Stir until smooth and allow it to cool slightly.
Frost one cake layer with coffee cream and top with the second layer.
Pour the ganache over the top and spread evenly.
Allow the ganache to set for 10 minutes before serving.
