Preheat your oven to 350°F (175°C). Grease and flour a cake pan.
In a mixing bowl, whisk together the flour, sugar, baking powder, and baking soda.
Add the softened butter, eggs, brewed coffee, and vanilla extract. Mix until smooth.
Pour the batter into the prepared cake pan and bake for 30 minutes or until a toothpick inserted into the center comes out clean.
Allow the cake to cool completely before frosting.
For the frosting, whip the heavy cream until it forms soft peaks. Add the powdered sugar and instant coffee granules, and continue to whip until stiff peaks form.
Spread the frosting over the cooled cake. Serve and enjoy!
Notes
This cake pairs wonderfully with a hot cup of coffee. Enjoy!
