Pumpkin Spice Latte is one of the most beloved Pumpkin Autumn treat, so why don't turn it into a delicious cake?This cake is made with a soft sponge cake soaked into Pumpkin Spice Latte made in a classic way (and so much better than the Starbucks one :D): homemade pumpkin puree, sugar, spices, milk and espresso coffee.You know I'm Italian so I make my Espresso Coffee with a traditional Moka pot, but you can prepare your Espresso in your favourite way.After you pour the Pumpkin Spice Latte bath on your cake, you have to wait at least 2 hours (better overnight) that your sponge cake absorbs all that delicious latte: please, do not skip this step! I usually wait overnight so the cake turns out incredibly moist, full of Pumpkin Spice Latte and so rich in flavor!The topping is a simply whipped cream scented with cinnamon. I chose to not sweeten my whipping cream because I think the cake is enough sweet for me; feel free to add a bit of powdered sugar if you like.
