Pumpkin Spice Latte Cake That Stays Moist for Days

May 9, 2026

Pumpkin spice latte cake is basically the cozy coffee shop drink turned into something you can slice. You get pumpkin purée for moisture, espresso powder for that bitter edge (so it doesn’t just taste like a candle aisle), and a cinnamon glaze that sets into a crackly top.

If you’re making this on a weeknight with kids orbiting the kitchen, bake it in a loaf pan and line the pan with parchment so you can lift it out fast and get it cooling on a rack (cooling is the difference between “nice glaze” and “sad glaze puddle”). I first tested a swirl version and decided it was more work than payoff for a cake that’s meant to be low-drama.

Ingredients

Cake (8.5 x 4.5 in / 21 x 11 cm loaf; serves 2–4)

All-purpose flour: 190 g (1 1/2 cups)
Baking powder: 6 g (1 1/2 tsp)
Baking soda: 3 g (1/2 tsp)
Fine salt: 3 g (1/2 tsp)
Pumpkin pie spice: 5 g (2 tsp) (or use 1 1/2 tsp cinnamon + 1/2 tsp ground ginger + 1/4 tsp nutmeg + pinch cloves)
Instant espresso powder: 4–6 g (2–3 tsp) (this is the latte part)
Light brown sugar, packed: 110 g (1/2 cup)
Granulated sugar: 50 g (1/4 cup)
Neutral oil (canola/avocado/vegetable): 80 g (1/3 cup)
Large egg: 1
Pumpkin purée (plain canned pumpkin, not pie filling): 225 g (3/4 cup + 2 Tbsp)
Buttermilk: 60 g (1/4 cup) (plain kefir works; whole milk + 1 tsp lemon juice is fine in a pinch)
Vanilla extract: 5 g (1 tsp)

Cinnamon glaze

Powdered sugar: 120 g (1 cup)
Ground cinnamon: 1–2 g (1/2–1 tsp)
Pinch of salt: small pinch
Milk or strong brewed coffee: 15–30 g (1–2 Tbsp) (start small)
Vanilla extract: 2 g (1/2 tsp)

Step-by-Step Pumpkin Spice Latte Cake

Heat the oven to 175°C (350°F). Grease an 8.5 x 4.5 in (21 x 11 cm) loaf pan and line it with a parchment sling so you can lift the cake out.
In a medium bowl, whisk the dry ingredients: flour, baking powder, baking soda, salt, pumpkin pie spice, and espresso powder. Break up any espresso powder clumps with your fingers—those show up as bitter specks later.
In a large bowl, whisk brown sugar, granulated sugar, and oil until it looks like wet sand. Whisk in the egg until the mixture loosens and looks glossy, about 20 seconds.
Add the pumpkin purée and vanilla and whisk until smooth. The batter will look thick and a little dull at this point; that’s normal.
Switch to a spatula. Add half the dry mix and fold until you only see a few streaks of flour. Pour in the buttermilk and fold again. Add the remaining dry mix and fold just until combined.

One thing — don’t “beat out the lumps.” Overmixing makes this kind of pumpkin loaf go from tender to rubbery fast.
Scrape the batter into the pan and smooth the top. Tap the pan on the counter a couple times to pop big air bubbles.
Bake 45–60 minutes, depending on your pan and oven. Start checking at 45.

You’re looking for a domed top with a long crack down the center.
A toothpick in the middle should come out with moist crumbs, not wet batter.

Heads up: if the top is browning hard at the 35–40 minute mark, tent loosely with foil and keep going.

Cool in the pan 10 minutes, then lift the cake out and cool fully on a rack.
Make the glaze: whisk powdered sugar, cinnamon, salt, vanilla, and 1 Tbsp milk/coffee. Add more liquid a teaspoon at a time until it’s thick but pourable. If it ribbons off the whisk and disappears back into the bowl in about 2–3 seconds, you’re there.
Glaze the cooled cake. Let it set 15–20 minutes before slicing.

(If you glaze while warm, it’ll melt and soak in. Tasty, but it won’t look like a glaze—more like a sticky sheen.)

What to Expect

This bakes up as a dense-but-tender loaf, not a fluffy birthday cake. The crumb is moist with a tight, even structure, and the coffee note sits behind the pumpkin spices instead of screaming “mocha.” The cinnamon glaze sets with a thin crust, then softens slightly by day two.

Different espresso powders vary a lot. If yours is aggressively dark, stick to 2 tsp the first time.

Ways to Change It Up

If you want it dairy-free, use an unsweetened oat milk “buttermilk” (oat milk + a little lemon juice) and glaze with oat milk. It works, but the crumb won’t be quite as plush.
More “coffee shop” energy: swap 1 Tbsp (15 g) of the milk in the glaze for strong brewed coffee and add a pinch of cinnamon on top while the glaze is wet.
Bundt pan? You can, but I wouldn’t bother unless you’re feeding more than 4. A bundt needs a bigger batch to bake evenly; with this small amount, you’ll fight dry edges.

Serving and Storage

Serve thick slices with black coffee or chai. If you’re leaning into dessert, a spoonful of lightly sweetened whipped cream on the side doesn’t hurt.

Room temp storage: keep it covered up to 3 days. The glaze will stay fine; it just gets softer.

Fridge storage: up to 5 days, tightly wrapped. Bring slices to room temp for 20 minutes so the spices come back.

Freezing: wrap unglazed slices well and freeze up to 2 months. Thaw at room temp, then glaze.

For a little context on why this flavor combo became such a big deal, Smithsonian Magazine has a solid explainer on the PSL’s rise as a seasonal phenomenon: Smithsonian Magazine on the Pumpkin Spice Latte turning 20. And if you’ve ever wondered why recipes push espresso powder instead of brewed coffee, this is the practical reason (flavor without extra liquid): Bakepedia’s guide to instant espresso powder.

Common Questions

Can I use pumpkin pie filling instead of pumpkin purée?
No. Pumpkin pie filling has sugar and spices already, and it’ll throw off both sweetness and structure.

I don’t have espresso powder. Can I use instant coffee?
Yes, but it’s weaker. Use 3–4 tsp instant coffee granules, and dissolve them in the buttermilk first so you don’t get crunchy bits.

Why did my loaf sink in the middle?
Usually it’s underbaking. Pumpkin loaves can look done because the top sets early, but the center still needs time. Bake until the tester has moist crumbs, then give it another 3–5 minutes if you’re unsure.

Can I make the glaze thicker/thinner?
Absolutely. For thicker, add more powdered sugar. For thinner, add liquid by the teaspoon. Don’t dump in milk or it’ll go from “glaze” to “icing soup.”

Can I bake this as muffins?
Yep. Fill a lined muffin tin about 3/4 full and bake at 175°C (350°F) for about 18–22 minutes. Glaze once cool.

If you make this, tell me which direction you took the glaze—milk-only, coffee-spiked, or heavy on the cinnamon. I’m nosy about other people’s “just one more pinch” habits with spice.
