Pumpkin cupcakes with espresso dissolved into the batter, finished with a cream cheese frosting that carries espresso of its own.
Twenty-five minutes of work, 18 to 21 in the oven, and a full cool before frosting. Twelve cupcakes.
Why This Recipe Works
- Espresso powder dissolved in hot water rather than added dry is the difference between a coffee-flavoured cupcake and a cupcake with bitter specks in it. One tablespoon of powder into one tablespoon of water is a thick, strong shot.
- Baking powder and baking soda together. The soda reacts with the acidity of pumpkin and brown sugar; the powder guarantees the lift a cupcake needs to dome above its liner.
- A cup and a half of flour to three-quarters of a cup of puree is a lighter ratio than the bars or the coffee cake use, and it has to be — a heavy batter in a paper liner sinks in the middle.
- Cream cheese and butter in a four-to-one ratio by weight gives a frosting that pipes. All cream cheese would be too soft to hold a swirl; all butter would lose the tang that balances two cups of powdered sugar.
- The cupcakes must be completely cool before step 7. Cream cheese frosting on a warm cake does not soften slightly — it slides off.
The Four Things Holding Each Other Up
This is a latte translated into a cupcake, and the translation only works because each element has a counterweight. Every axis below maps to an ingredient you can point at in the list.
- Coffee1 tbsp espresso powder in the batter, 1 1/2 tsp in the frosting
- Present twice, at different strengths, which is the whole design. The batter carries a dissolved, rounded coffee note; the frosting carries a sharper undissolved one. Take it out of either half and this stops being a latte cupcake.
- Squash and spice3/4 cup pumpkin puree, 1 1/2 tsp pumpkin pie spice
- Three-quarters of a cup rather than a full one. Pumpkin is heavy and wet, and a cupcake has to rise higher and faster than a bar — this quantity flavours the crumb without weighing it down.
- Sweetness3/4 cup brown sugar in the cake, 2 cups powdered sugar in the frosting
- Deliberately uneven. The cake is only lightly sweet because the frosting is not; brown sugar in the batter also brings the molasses edge that reads as caramel next to the coffee.
- Tang and fat8 oz cream cheese, 4 tbsp butter, 1/3 cup whole milk
- The cream cheese is what stops two cups of powdered sugar being cloying, and the four tablespoons of butter are what let the frosting hold a piped swirl instead of slumping. Whole milk in the batter keeps the crumb soft.
Beat the frosting until it is genuinely smooth before judging it — undissolved espresso powder tastes harsher in the bowl than it does once it has had a minute to hydrate in the cream cheese.
Ingredient Notes
- Instant espresso powder
- Used twice and handled differently each time: a tablespoon dissolved in hot water for the batter, a teaspoon and a half added dry to the frosting. Instant espresso, not ground coffee beans, which will not dissolve at all.
- Cream cheese, softened
- Full-fat block, eight ounces, properly at room temperature. Tub-style spreadable cream cheese carries extra water and gives a frosting too loose to pipe.
- Unsalted butter, softened
- Four tablespoons. It is the structure in the frosting — the reason a swirl stays a swirl in a warm room.
- Pumpkin puree
- Three-quarters of a cup, plain puree. Less than the bars use, on purpose, because a cupcake needs a lighter batter.
- Whole milk
- A third of a cup. It thins the batter enough to divide evenly between twelve liners and keeps the crumb tender.
How to Make It
Heat the oven and line the pan
Heat oven to 350°F and line a 12-cup muffin pan with paper liners.
Whisk the dry ingredients
Whisk flour, baking powder, baking soda, pumpkin pie spice and salt.
Whisk the wet ingredients
Whisk eggs, pumpkin, brown sugar, oil, milk, the dissolved espresso and vanilla.
Fold them together
Fold the dry ingredients into the wet just until combined.
Bake and cool completely
Divide the batter among the cups and bake 18 to 21 minutes, until a tester comes out clean. Cool completely.
Beat the espresso frosting
Beat cream cheese and butter until smooth. Beat in powdered sugar, espresso powder and vanilla.
Frost
Frost the cooled cupcakes.
Success Tips
- Dissolve the batter's espresso first and let it cool, so it does not warm the eggs.
- Take the cream cheese and butter out at the same time; one cold and one soft will never beat smooth together.
- Fill the liners about two-thirds full so the domes rise rather than spill.
- Wait for the cupcakes to reach room temperature all the way through — a warm centre melts the frosting from underneath.
- Sift the powdered sugar if the tub has been open a while; lumps in a cream cheese frosting never beat out.
Serving Ideas
As they are, with coffee, which is a slightly absurd pairing that nonetheless works. A light dusting of ground cinnamon or espresso powder over the swirl finishes them.
Storage and Reheating
Refrigerate
Refrigerate frosted cupcakes in a sealed container up to 4 days. Cream cheese frosting is not a room-temperature keeper.
Freeze
Freeze the UNFROSTED cupcakes for up to 2 months and frost after thawing. Piped cream cheese frosting weeps as it thaws.
Reheat
None. Bring them out of the fridge twenty minutes ahead — cold blunts both the spice and the coffee.
Frequently Asked Questions
Can I leave out the espresso powder?
You can bake it, but you will have a pumpkin cupcake with cream cheese frosting rather than this recipe. The coffee in both the batter and the frosting is the whole identity of it.
Is instant coffee granules the same as instant espresso powder?
Not quite. Espresso powder is finer and considerably stronger, so ordinary instant coffee gives a weaker result at the same measure. Dissolve it the same way if it is what you have.
My frosting is too soft to pipe.
Usually spreadable tub cream cheese rather than block, or a warm kitchen. Twenty minutes in the fridge firms it up enough to pipe; if it is the tub, no amount of extra sugar will fix it properly.
How is this different from the pumpkin cream cheese coffee cake?
That one is a single 9-inch square cake with the cream cheese baked inside it and streusel on top, and it contains no coffee at all despite the name. These are twelve individual cupcakes with espresso in the crumb and espresso in the frosting.
