This pumpkin spice latte cake is soft, warmly spiced, and topped with a tangy cream cheese frosting infused with espresso for the perfect PSL twist. With cozy flavors of pumpkin pie spice and a bold kick of coffee, it's a fall dessert that feels indulgent, yet is totally approachable.
Grease and line an 8x8-inch pan with parchment paper slings. Preheat the oven to 350℉.
In a large bowl, whisk together the flour, baking soda, pumpkin pie spice and salt and set aside.
1¾ cups all purpose flour, 1 teaspoon baking soda, 1 tablespoon pumpkin pie spice, ½ teaspoon kosher salt
In the bowl of a stand mixer fitted with the paddle attachment (or with a hand mixer), cream together the butter, sugar and vanilla until smooth and fluffy, about 3 minutes.
¼ cup unsalted butter, 1 cup granulated sugar, 1 teaspoon vanilla extract
With the mixer on low speed, add in one egg at a time until incorporated, then mix in the pumpkin puree. Scrape down the sides.
2 large eggs, 1 cup canned pumpkin puree
Add half of the flour mixture and mix, then all of the buttermilk, and then the remaining flour mixture. Mix until just combined. Use a rubber spatula to scrape down the sides and combine any additional flour by hand.
¾ cup buttermilk
Spread the cake evenly into the pan, then bake for 28-32 minutes until a toothpick inserted into the center comes with a few moist crumbs but no wet batter.
Cool completely on a wire rack.
Espresso Frosting
Mix the espresso powder with the milk to dissolve.
Cream together the butter, powdered sugar, vanilla, pumpkin pie spice, and espresso mixture until smooth, a few minutes. Add in the cream cheese and mix to combine, then scrape down the sides and mix again until very smooth.
¼ cup unsalted butter, 2 cups powdered sugar, 2 teaspoons vanilla extract, 1 teaspoon pumpkin pie spice, 8 oz cream cheese
Spread on top of the cooled cake, then dust with a mixture of ground cinnamon and espresso powder.
