Single-Serve Marbled Pumpkin Chocolate Muffin
Okay, listen. There are some days when all I want is a little something sweet โ not a whole dozen muffins, not a full loaf cake, not a โshare with your friendsโ situation. I just want one warm, cozy, chocolatey muffin, all to myself. Enter: this single-serve marbled pumpkin chocolate muffin.
Itโs fall in muffin form โ half rich chocolate, half pumpkin spice cozy, perfectly swirled together so you never have to choose between the two. Itโs giving โchilly October afternoon,โ โsocks and oversized sweatshirt,โ โwatching Hocus Pocus with a candle burningโ energy.
I made this on a total whim one day when I had a little bit of pumpkin purรฉe left in the fridge and didnโt want to waste it. You know how that happens โ you make pumpkin bread, youโve got two tablespoons left, and it just sits there until you forget about it. Not this time! I decided that leftover pumpkin was destined for greatness, and thusโฆ this muffin was born.
And honestly? Iโm obsessed. Itโs soft, moist (sorry but itโs true), just the right amount of sweet, and the marbling makes it feel fancy even though itโs really just me, a spoon, and one muffin tin cup living our best lives.
The chocolate side is rich and fudgy thanks to a mix of Dutch and black cocoa (plus a tiny splash of hot coffee because, of course), and the pumpkin side is warm and spiced and smells like straight-up fall magic. When they swirl together, you get this perfect bite of cozy spice and deep chocolate all at once. Heaven.

๐ซ Ingredients
Youโll need one small egg, lightly beaten โ youโll use small portions of it in each batter.
For the chocolate batter:
- 2 tbsp all-purpose flour
- 1 ยฝ tsp granulated sugar
- 1 tsp Dutch-process cocoa powder
- 1 tsp black cocoa powder
- Pinch of baking powder
- Pinch of salt
- 1 tbsp milk
- 2 tsp neutral oil (like canola or vegetable)
- 1 tsp of your beaten egg (from that whole egg)
- Drop of vanilla extract
- 1 tsp hot coffee (to deepen the chocolate flavor)
For the pumpkin batter:
- 2 tbsp + 1 tsp all-purpose flour
- Pinch of baking powder
- Pinch of baking soda
- Pinch of salt
- ยผ tsp pumpkin pie spice
- 1 tbsp brown sugar
- 1 tsp granulated sugar
- 2 tsp neutral oil
- 1 tsp milk
- 1 tsp of your beaten egg (from the same egg)
- Drop of vanilla extract
- 2 tbsp pumpkin purรฉe
Youโll have a tiny bit of egg leftover, but thatโs okay โ weโre keeping both batters balanced and perfect.

๐ง Directions
- Preheat your oven to 350ยฐF (175ยฐC). Lightly grease or line one muffin cup in your tin.
- Make the chocolate batter: In a small bowl, whisk together flour, sugars, cocoa powders, baking powder, and salt. Add in milk, oil, vanilla, egg, and coffee. Stir just until smooth and glossy.
- Make the pumpkin batter: In another small bowl, whisk together flour, baking powder, baking soda, salt, and pumpkin pie spice. Stir in brown sugar, granulated sugar, oil, milk, vanilla, pumpkin purรฉe, and egg. Mix until just combined.
- Layer and swirl: Spoon a bit of each batter into your prepared muffin cup, alternating between pumpkin and chocolate layers. Use a toothpick or knife to gently swirl them together โ not too much, just enough to make those pretty marbled streaks.
- Bake for 18โ22 minutes, or until the top springs back when touched and a toothpick comes out clean.
- Cool slightly, then enjoy warm with a drizzle of chocolate sauce, a sprinkle of powdered sugar, or honestly just as is โ itโs that good.

๐ Cozy Muffin Moment
Thereโs something about having a single muffin all to yourself that just feels special. Itโs the ultimate little self-care bake โ minimal mess, minimal dishes, maximum reward. The edges get that slightly chewy, rich texture while the center stays soft and melty from the pumpkin.
And if youโre anything like me, the swirl process might just be your favorite part. Thereโs no way to do it wrong. Even if you over-swirl (guilty), it still bakes up beautiful and delicious. Plus, the smell that fills your kitchen while itโs in the oven? Unreal. Pumpkin spice meets brownie heaven.
If youโve got a cozy night planned โ maybe a fall movie marathon or just a quiet moment with a cup of coffee โ this is the treat you want beside you.

๐งก Storage (if you somehow donโt eat it immediately)
If youโre saving it for later (which, impressive self-control), wrap it tightly or store in a little airtight container at room temp for a day. Warm it up for about 10 seconds in the microwave the next day, and itโs just as soft and fresh as when it came out of the oven.
