This creamy Pumpkin Spice Buttercream blends rich butter, pumpkin puree, and warm autumn spices for a smooth, flavorful frosting that’s perfect for cakes, cupcakes, cookies, and more.
Prepare all ingredients and ensure butter is softened to room temperature.
Beat the butter with an electric mixer for 2–3 minutes until creamy and light.
Gradually add powdered sugar, mixing on low speed to incorporate fully.
Add pumpkin puree and vanilla extract, then mix until smooth.
Mix in pumpkin pie spice and adjust the consistency by adding heavy cream 1 tablespoon at a time.
Taste and adjust flavor with more spice or sugar as desired, then use immediately or store refrigerated.
Notes
For a vegan version, use plant-based butter and coconut cream instead of heavy cream. Store in the fridge for up to 1 week or freeze for 3 months. Great for fall cakes, cupcakes, and cookies.
