1Preheat your oven to 180°C (350°F) and grease a baking pan.
In a large bowl, cream together the unsalted butter and sugar until light and fluffy.
Add the eggs one at a time, beating well after each addition.
Mix in the coffee until well combined.
In a separate bowl, sift together the cake flour, cinnamon, and salt.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
Pour the batter into the prepared baking pan and smooth the top.
Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
Allow the cake to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
Serve and enjoy your delicious Cinnamon Coffee Cake!
