Preheat the Oven: Set your oven temperature to 350°F (175°C). Line a muffin tin with cupcake liners to prepare for baking.
Mix Dry Ingredients: In a medium mixing bowl, whisk together the flour, baking powder, baking soda, salt, and pumpkin spice blend until they are thoroughly blended and free of lumps.
Cream Butter and Sugar: In a large mixing bowl, beat the softened butter and granulated sugar together with an electric mixer on medium speed until the mixture becomes light and fluffy, about 3-5 minutes.
Add Eggs and Pumpkin: Incorporate the eggs one at a time, mixing well after each addition to ensure a smooth batter. Next, add the pumpkin puree and vanilla extract, and mix until everything is well combined and smooth.
Combine Wet and Dry: Gradually add the dry mixture to the butter-sugar-egg mixture, alternating with the cooled brewed coffee. Start and finish with the flour mixture. Mix gently until just combined; be careful not to overmix to keep the cupcakes light.
Fill Cupcake Liners: Use a spoon or ice cream scoop to divide the batter evenly among the prepared cupcake liners, filling each about two-thirds full for best results.
Bake: Place the muffin tin in the preheated oven and bake for 18-20 minutes, or until a toothpick inserted into the center of a cupcake comes out clean. Allow the cupcakes to cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.
Prepare the Frosting: In a clean large mixing bowl, beat the softened butter using an electric mixer until creamy and smooth. Gradually add in the powdered sugar, followed by the brewed coffee, vanilla extract, and a pinch of salt. Beat the mixture on medium-high speed until it becomes light, fluffy, and fully combined.
Frost the Cupcakes: Once the cupcakes are completely cooled, take a piping bag fitted with a decorative tip or a knife, and generously apply the coffee buttercream frosting on top of each cupcake.
Serve: Enhance your beautifully frosted Pumpkin Spice Latte Cupcakes by garnishing each one with a light sprinkle of pumpkin spice or placing a whole coffee bean on top for an extra touch of decor and flavor.
