The espresso powder disappears into the buttermilk, and the kitchen starts smelling like coffee before the cake even goes in the oven. That little pour is what gives this Pumpkin Spice Latte Cake its coffee-shop note without turning the batter thin or making the spice taste sharp. It bakes up tender in a 9×13-inch pan, then gets a thick layer of cream cheese frosting once it’s completely cool.
I like this cake because the pumpkin and warm spices are right up front, while the espresso stays in the background. The batter comes together in one large bowl after the dry ingredients are whisked separately, so there’s no complicated mixing routine. Give the cake time to cool before frosting; that wait is what keeps the frosting plush instead of sliding across the surface. Each slice has a soft, spiced crumb under a tangy, creamy finish.
Kitchen Note
Stop folding as soon as the last dry streak disappears. A few small lumps are better than mixing until the batter looks perfectly smooth; overworking it can leave the cake tighter.
Save this Pumpkin Spice Latte Cake for its soft pumpkin crumb, espresso warmth, and generous cream cheese frosting.
Why the Espresso Goes Into the Buttermilk First
Instant espresso powder needs to dissolve before it meets the rest of the batter. Stirring it into the buttermilk gives the fine powder a chance to disperse evenly, so you don’t end up with concentrated coffee flecks in one bite and no coffee flavor in the next. The buttermilk also gives you a smooth liquid mixture that blends easily with the pumpkin, eggs, sugars, and oil.
This order keeps the coffee note present but balanced. The pumpkin and spices bring plenty of character, so the espresso should deepen that warm, roasted flavor rather than take over. Dissolving the powder first also avoids adding brewed coffee, which would bring extra liquid and change the batter’s balance. Once the espresso buttermilk is whisked into the pumpkin mixture, the dry ingredients can go in without a separate coffee step later.
What Gives This Cake Its Pumpkin-Spice Latte Character
- Pumpkin puree — It brings moisture and the earthy pumpkin base that holds the spices together. Use plain pumpkin puree, not pumpkin pie filling, which is already sweetened and spiced.
- Buttermilk — Its tang keeps the sweet, warmly spiced cake from tasting flat, and it gives the batter enough liquid to mix smoothly. Shake it before measuring so the texture is even.
- Instant espresso powder — This is the clearest way to add coffee flavor without pouring extra liquid into the batter. Choose a fresh jar with a strong aroma; stale powder tastes muted.
- Ground cinnamon, ginger, nutmeg, and cloves — Together they make the pumpkin taste rounded rather than simply sweet. Fresh, fragrant spices matter most here; if a jar smells dusty instead of warm, its flavor will be faint.
- Neutral oil — Oil keeps the cake tender and moist without adding a competing flavor. A neutral-tasting oil is the right choice; strongly flavored oils can distract from the pumpkin and espresso.
- Granulated and light brown sugars — The two sugars contribute sweetness with slightly different results: brown sugar brings a deeper, molasses-like note, while granulated sugar keeps that flavor from becoming too heavy.
- Cream cheese and butter — Both need to be softened before beating so the frosting turns smooth. The cream cheese supplies tang, and butter gives the powdered-sugar frosting body.
Mixing and Baking the Cake Without Losing Its Tender Crumb
Whisk the dry ingredients and dissolve the espresso
Heat the oven to 350°F and coat a 9×13-inch baking pan with nonstick cooking spray. In a medium bowl, whisk the flour with the baking powder, baking soda, cinnamon, ginger, nutmeg, cloves, and salt so the leaveners and spices are spread through the flour. In a small bowl, stir the instant espresso powder into the buttermilk until it dissolves. Set both mixtures aside while you build the pumpkin batter.
Bring the pumpkin batter together
Whisk the pumpkin puree, granulated sugar, brown sugar, eggs, oil, vanilla, and espresso-buttermilk mixture in a large bowl until smooth. Add the flour mixture to the pumpkin mixture, then fold until no dry streaks remain. Scrape along the bottom and sides of the bowl as you fold, where flour can hide. Stop once the batter is combined rather than beating it smooth.
Bake until the center gives a moist-crumb cue
Spread the batter evenly in the prepared pan so it bakes at a consistent thickness. Bake for 30 to 35 minutes, checking the center with a toothpick near the end of that window. The cake is ready when the toothpick comes out with a few moist crumbs; wet batter means it needs more time. Set the pan on a wire rack and let the cake cool completely, about 1 to 2 hours.
Beat the frosting and finish the cooled cake
Beat the softened cream cheese and butter in a large bowl until smooth before adding the powdered sugar and vanilla. Beat again until the frosting looks fluffy, scraping the bowl if any unmixed patches cling to the sides. Spread it over the completely cooled cake. Frosting a warm cake softens the mixture and makes it harder to keep an even layer.
Three Easy Ways to Change the Coffee, Spice, or Flour
Make it a cinnamon-forward pumpkin cake
Leave out the ginger, nutmeg, and cloves while keeping the cinnamon. The result is simpler and more cinnamon-led, with less of the layered chai-like warmth from the full spice mix.
Make it without the espresso
Skip the espresso powder and whisk the buttermilk directly into the pumpkin mixture. The cake will still have its pumpkin and spice character, but it won’t have the roasted coffee note that makes it taste like a latte.
Use a gluten-free flour blend
Replace the all-purpose flour with the same measured amount of a cup-for-cup gluten-free baking blend that contains xanthan gum. Fold gently, since gluten-free cake batter can become gummy if overmixed; the crumb may be a little more delicate than the wheat-flour version.
Storage and Reheating
- Refrigerator: Cover the frosted cake and refrigerate it for up to 4 days. The crumb firms up when cold, so let slices stand briefly before serving if you prefer a softer texture.
- Freezer: Freeze slices until the frosting is firm, then wrap each slice tightly and freeze for up to 2 months. Thaw, still wrapped, in the refrigerator; the frosting may be a little less silky after freezing.
- Reheating: Don’t microwave slices with cream cheese frosting, which can melt and turn greasy. This cake is best served cool or after a short rest at room temperature.
