I used to think chocolate and pumpkin was a weird combination until I tried it at a friend’s potluck last fall. Now I can’t get enough of it. There’s something about the rich chocolate paired with the mild, earthy pumpkin that just works.

Most people stick to pumpkin pie or plain chocolate cake, but this pumpkin chocolate fudge cake gives you the best of both worlds. It’s moist from the pumpkin puree and has that deep chocolate flavor that makes everyone ask for seconds. Plus, it’s way easier to make than you’d think—no fancy techniques required.

Why You’ll Love This Pumpkin Chocolate Fudge Cake

Only two ingredients – You literally just need chocolate chips and pumpkin puree to make this rich, decadent cake. It doesn’t get much simpler than that!
Naturally gluten-free – Perfect for anyone avoiding gluten, this cake uses no flour at all while still delivering that fudgy texture you crave.
Healthier indulgence – The pumpkin adds moisture and nutrients while cutting down on the need for butter or oil, making this a guilt-free treat.
Perfect fall dessert – The combination of rich chocolate and warm pumpkin flavors captures all the cozy vibes of autumn in every bite.
Impressive yet easy – Your guests will never believe something this rich and chocolatey came from just two simple ingredients.

What Kind of Pumpkin Puree Should I Use?

For this fudge cake, you’ll want to use plain pumpkin puree, not pumpkin pie filling – there’s a big difference! Pumpkin pie filling already has spices and sugar added, which will throw off the balance of your cake. Look for cans labeled “100% pure pumpkin” or “pumpkin puree” in the baking aisle. Libby’s is a popular brand that works well, but any plain pumpkin puree will do the trick. If you’re feeling ambitious, you can even make your own by roasting a sugar pumpkin and pureeing the flesh, though the canned version is much more convenient and consistent.

Options for Substitutions

This simple two-ingredient cake is pretty straightforward, but here are a few swaps you can make:

Semi-sweet chocolate chips: You can use dark chocolate chips for a richer flavor, or milk chocolate chips if you prefer something sweeter. Chopped chocolate bars work too – just make sure to use the same amount by weight.
Pumpkin puree: Make sure you’re using plain pumpkin puree, not pumpkin pie filling. If you can’t find canned pumpkin, you can roast and puree your own sugar pumpkin, or try sweet potato puree as a substitute – it’ll give you a similar texture and natural sweetness.
Chocolate type variations: For a fun twist, try using white chocolate chips mixed with a pinch of pumpkin pie spice, or go half dark chocolate and half butterscotch chips for extra fall flavor.

Watch Out for These Mistakes While Baking

The biggest mistake when making this simple two-ingredient fudge cake is using pumpkin pie filling instead of pure pumpkin puree – the added spices and sugar in pie filling will throw off the texture and sweetness balance completely. Another common error is not melting the chocolate properly, so use a double boiler or microwave in 30-second intervals, stirring between each round to prevent the chocolate from seizing up and becoming grainy. Make sure your pumpkin puree is at room temperature before mixing it with the melted chocolate, as cold puree can cause the chocolate to harden too quickly and create lumps. Finally, don’t overbake this fudgy treat – it should still look slightly underdone in the center when you remove it from the oven, as it will continue to set as it cools.

What to Serve With Pumpkin Chocolate Fudge Cake?

This rich, fudgy cake is perfect on its own, but a dollop of whipped cream or a scoop of vanilla ice cream makes it even better. The cool, creamy texture is a nice contrast to the dense chocolate and adds a little lightness to each bite. If you want to play up the fall flavors, try serving it with some cinnamon ice cream or even a drizzle of caramel sauce. A hot cup of coffee or a glass of cold milk also pairs really well with this decadent treat, especially since the chocolate can be pretty rich.

Storage Instructions

Keep Fresh: This fudge cake stays perfectly moist when covered tightly with plastic wrap or stored in an airtight container at room temperature for up to 5 days. I actually think it tastes even better the next day once all those pumpkin and chocolate flavors have had time to meld together.

Refrigerate: If your kitchen is warm or you want to keep it extra fresh, pop it in the fridge for up to a week. Just let it sit out for about 10-15 minutes before serving so it’s not too firm. The cold actually makes it taste more like a rich fudge!

Freeze: Cut the cake into individual squares and wrap each piece in plastic wrap, then store in a freezer bag for up to 3 months. When you want a sweet treat, just thaw a piece at room temperature for about 30 minutes and it’s ready to enjoy.

Ingredients

2 1/4 cups melted semi-sweet chocolate chips
1 cup pureed pumpkin

Step 1: Prepare the Muffin Tin

Line 10 compartments of a standard muffin tin with paper liners.

For extra sturdiness, I like to double up on the paper liners.

There’s no need to mist them with oil spray.

Set the tin aside once prepared.

Step 2: Melt the Chocolate Chips

2 1/4 cups melted semi-sweet chocolate chips

Melt the semi-sweet chocolate chips using a double boiler or by microwaving in short bursts, stirring in between, until smooth.

Be careful not to overheat the chocolate, as it can seize.

If using a double boiler, gently heat while stirring constantly until fully melted.

Step 3: Mix Chocolate with Pumpkin

2 1/4 cups melted semi-sweet chocolate chips (from Step 2)
1 cup pureed pumpkin

Add the pureed pumpkin to the melted chocolate chips and stir well until the mixture is completely smooth and no streaks of pumpkin remain.

A silicone spatula works great for thorough mixing.

Step 4: Divide Batter and Smooth Tops

Chocolate-pumpkin mixture (from Step 3)

Portion the chocolate-pumpkin batter evenly into the 10 prepared muffin liners.

Smooth the tops with the back of a spoon and gently tap the muffin tin on the counter a few times to level out the mixture and eliminate air bubbles.

I always tap the tray—it helps create a neater finish.

Step 5: Chill Until Firm and Serve

Place the filled muffin tin in the refrigerator and let the cakes firm up for at least 2 hours.

Once firm, they are ready to serve.

For a special touch, I sometimes serve these with a few fresh berries and a sprinkle of dark chocolate shavings on top.
