Ingredients for 3 ingredient pumpkin spice cake
Three simple ingredients transform into a moist, spiced cake that tastes like autumn in every bite.
| Ingredient | Amount | Notes |
|---|---|---|
| Canned Pumpkin Puree 🎃 | 1 cup | Unsweetened, not pumpkin pie filling |
| Pumpkin Spice Mix 🌶️ | 2 tbsp | Store-bought or homemade blend |
| Large Eggs 🥚 | 2 whole | Room temperature preferred |
| Granulated Sugar 🍚 | ½ cup | White or light brown |
| All-Purpose Flour 🌾 | 1 cup | Sifted for even texture |
| Baking Powder 🍞 | 1 tsp | Aluminum-free preferred |
| Salt 🧂 | ¼ tsp | Fine sea salt |
| Vegetable Oil 🫒 | ¼ cup | Light or canola |
| Vanilla Extract 🌸 | 1 tsp | Pure extract preferred |
The pumpkin puree makes or breaks this cake—Libby's or Storebrand are my go-tos, but any unsweetened canned pumpkin works. If you're feeling fancy, grab organic pumpkin puree from Trader Joe's—it's smoother and has more flavor. The spice mix is where the magic happens: Penzeys or McCormick have great pre-mixed options, but if you're making your own, aim for 1 tsp cinnamon, 0.5 tsp ginger, 0.5 tsp nutmeg, and a pinch of cloves. The eggs should be room temperature for even mixing—just take them out 10 minutes before you start.
No pumpkin spice mix? DIY it in 5 minutes—just blend 1 tsp cinnamon, 0.5 tsp ginger, 0.5 tsp nutmeg, and a pinch of cloves. Running low on eggs? Applesauce works in a pinch (replace 1 egg with 0.25 cup unsweetened applesauce), but the texture won't be quite as tender. For the sugar, coconut sugar or brown sugar adds depth, but white sugar keeps it classic. The flour? King Arthur or Bob's Red Mill are my favorites—they bake up lighter. If you're out of baking powder, baking soda plus cream of tartar (half the amount) is a solid swap.
This cake keeps beautifully—3 days at room temperature wrapped in foil, or 1 week in the fridge in an airtight container. For leftovers, microwave 20 seconds to revive the moisture. Freezes like a dream: wrap slices in plastic and freeze for up to 3 months. I always make a double batch—one for now, one for later. The aroma alone while baking makes the whole kitchen smell like fall, so open windows if you're sensitive to strong scents.

Step-by-step instructions for 3 ingredient pumpkin spice cake
Here's how to make this wonderfully simple, moist pumpkin cake with just one bowl.
Combine Wet Ingredients for a Smooth Batter
In a large mixing bowl, add the 1 cup of canned pumpkin puree, 0.5 cup of granulated sugar, 0.25 cup of vegetable oil, and 1 teaspoon of vanilla extract. Using a whisk or electric mixer, combine these ingredients on medium speed for about 1 minute until they're fully incorporated. This ensures the sugar dissolves completely and the oil blends smoothly with the pumpkin.
The mixture should be uniform with no visible streaks of oil. Here's the thing - don't worry if it looks a bit thin at this stage. The flour will come next to thicken everything up. I like to scrape down the sides of the bowl with a rubber spatula at this point to make sure everything gets properly mixed.
Add Eggs and Spices for Perfect Texture
Next, add the 2 whole large eggs to the wet mixture. Mix again on medium speed for another 30 seconds until the eggs are fully combined and no streaks remain. Then add the 2 tablespoons of pumpkin spice mix and 0.25 teaspoon of salt. Mix just until these dry ingredients are evenly distributed throughout the batter.
This is where the magic happens for that perfect moist texture. The eggs provide structure while keeping the cake tender, and the spices will infuse throughout. I always use room temperature eggs for this recipe - they blend in more smoothly and help create a lighter texture. If your eggs are cold, let them sit at room temperature for about 30 minutes before using.
Gently Fold in the Flour for a Light Texture
Now it's time to add the 1 cup of all-purpose flour and 1 teaspoon of baking powder. The key here is to gently fold these dry ingredients into the wet mixture using a spatula. Mix just until combined - you should still see some small streaks of flour throughout the batter. Overmixing at this stage can develop gluten and make the cake slightly tough.
I like to use a folding motion with my spatula, lifting from the bottom of the bowl and gently turning the batter over itself. This creates a light, airy texture without overworking the flour. The batter should be thick but still pourable. If it's too thick, you can add 1-2 tablespoons of milk or water to help it flow more easily into the pan.
Bake Until Golden and Springy
Preheat your oven to 350°F. Grease an 8-inch round cake pan or line it with parchment paper. Pour the batter into the prepared pan and smooth the top with a spatula. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean and the top is golden brown.
The cake is done when it springs back slightly when you press the center gently with your finger. I always check at the 25-minute mark because ovens can vary. If the edges are browning too quickly, tent the cake with aluminum foil to prevent overbrowning while the center finishes baking. The cake should be moist but not gummy when done.
Cool and Enjoy Your Perfect Cake
Remove the cake from the oven and let it cool in the pan for 10 minutes. Then transfer it to a wire rack to cool completely. This cooling time is important - it allows the cake to set properly and makes slicing much easier. The cake will be moist but firm enough to slice cleanly after it's fully cooled.
Here's a pro tip: I like to dust the top with a little powdered sugar right after it comes out of the oven. This adds a nice finishing touch and helps keep the cake moist. Serve slices at room temperature for the best texture and flavor. This cake keeps well at room temperature for 2-3 days or can be refrigerated for up to 5 days if wrapped tightly in plastic wrap.
Pro Tips For Making 3 Ingredient Pumpkin Spice Cake
- Whisk Eggs First: Crack those eggs into a bowl before measuring anything else—this keeps them from getting watery when you add the pumpkin puree. I learned this the hard way when my first batch turned out like a sad, dense brick because the eggs got diluted mid-stir.
- Sift the Flour: Skip the sifting? Your cake will be dense and crumbly. Give that flour a good shake through a fine-mesh sieve—especially if it’s old or clumpy. Yes, it’s an extra 30 seconds, but your texture will thank you.
- Don’t Overmix: Stir just until the flour disappears—no more. I used to beat this batter like I was trying to win a mixing contest, and it always ended up tough. Think "gentle fold" until combined, like you’re tucking in a baby, not kneading bread.
- Test for Doneness: That toothpick check? Not foolproof. Pull the cake out when the edges are set but the center still jiggles slightly—it’ll firm up as it cools. If you wait for "clean," you’re risking a dry, overbaked mess. Trust the wiggle.
Dietary considerations for this 3 ingredient pumpkin spice cake
Gluten-Free Adaptation
For a gluten-free version, replace the 1 cup all-purpose flour with 1 cup gluten-free 1:1 baking flour like Bob's Red Mill or King Arthur. These blends work best because they include xanthan gum to mimic gluten's structure. I've tested this substitution and found the texture remains tender but slightly denser. If your blend lacks xanthan gum, add ½ teaspoon separately. Bake at 350°F for 30-35 minutes—gluten-free cakes often need extra time. 💡
Dairy-Free Options
This cake is naturally dairy-free, but you can enhance it further by using dairy-free vanilla extract (like McCormick's) and replacing the 2 eggs with 2 flax eggs (mix 2 tbsp ground flaxseed + 6 tbsp water, let sit for 5 minutes). The flax eggs add moisture and bind the cake similarly to regular eggs. For extra richness, fold in 2 tbsp coconut milk with the wet ingredients. The texture stays moist but may be slightly denser. 🥥
Lower Sugar Version
Cut the sugar by half (¼ cup granulated sugar) and replace the remaining ¼ cup with 2 tbsp unsweetened applesauce or 2 tbsp mashed banana for natural sweetness. The cake will still be tender but slightly less sweet. I've found this works best with 1 extra tbsp pumpkin spice mix to balance the flavor. For extra moisture, add 1 tbsp almond milk to the wet ingredients. 🍌
Nut-Free Considerations
This recipe is naturally nut-free, but always double-check your pumpkin spice mix and vanilla extract for cross-contamination warnings. If using homemade spice blends, ensure all spices are stored in nut-free containers. For added safety, prepare the cake in a dedicated nut-free kitchen area. The texture remains unchanged, but flavor safety is critical for nut allergies. 🚫
Vegan Adaptation
For a vegan version, replace the 2 eggs with 2 flax eggs (as above) and use vegan vanilla extract. Substitute the vegetable oil with applesauce or melted coconut oil for a plant-based fat. The cake will be slightly denser but still moist. I recommend adding ½ tsp baking soda to help with rise. Bake for 35-40 minutes at 350°F—vegan cakes often need extra time. 🌱

Frequently asked questions
Why does this cake only use 3 main ingredients?
The "3 ingredients" refers to the core flavor base: pumpkin puree, eggs, and pumpkin spice mix. The remaining ingredients (flour, sugar, oil, etc.) are essential baking components that create the structure and moisture. This approach simplifies the flavor profile while keeping all the cozy autumn spices you love. The magic happens when these simple elements combine to create a rich, spiced cake with minimal effort!
Can I make this cake without an electric mixer?
This recipe works perfectly with just a whisk or even a sturdy spoon. Simply mix the wet ingredients by hand until smooth, then fold in the dry ingredients using a spatula. The key is to mix just until combined—overmixing can make the cake dense. For the flour, gently fold it in with a spatula to maintain that light, airy texture.
How do I adjust the spice level?
For a stronger pumpkin spice flavor, increase the spice mix by 1 teaspoon (total 3 tbsp). For a milder taste, reduce to 1.5 tbsp. You can also adjust individual spices: add ¼ tsp extra cinnamon for warmth or ¼ tsp nutmeg for depth. Always taste the batter before baking—this cake is forgiving enough to adjust flavors easily!
What's the best way to serve this cake?
Warm slices pair perfectly with whipped cream, vanilla ice cream, or a drizzle of caramel sauce. For a festive touch, dust with powdered sugar or add a sprinkle of cinnamon on top. Serve with a cup of chai tea or coffee for the ultimate autumn dessert experience. The cake's moist texture holds up well to toppings, so don't be shy with the extras!
Why did my cake turn out dense?
Overmixing the batter or overbaking are the most common causes. Mix just until combined (small flour streaks are fine) and check for doneness at 25 minutes. If your oven runs hot, reduce the temperature to 325°F. Also ensure your eggs are room temperature and your pumpkin puree is unsweetened. For extra moisture, try adding 1 tbsp applesauce to the wet ingredients.
