Ingredients You’ll Need
For the Pumpkin Cake
- 1 1/2 cups all-purpose flour
- 1 cup granulated sugar
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1 teaspoon ground cinnamon
- 1 cup pumpkin puree (not pumpkin pie filling)
- 1/3 cup vegetable oil
- 1/2 cup water
- 1 tablespoon white vinegar
- 1 teaspoon vanilla extract
- 1/2 teaspoon pumpkin pie spice (optional)
For the Cream Cheese Frosting
- 8 ounces cream cheese, softened
- 1/2 cup unsalted butter, softened
- 2 cups powdered sugar
- 1 teaspoon vanilla extract
- Pinch of salt
How to Make Pumpkin Wacky Cake with Cream Cheese Frosting
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C).
Lightly grease an 8×8-inch or 9×9-inch baking dish with butter or nonstick cooking spray.
You can also line the dish with parchment paper, leaving a little overhang to make removing the cooled cake easier.
Step 2: Combine the Dry Ingredients
In a large mixing bowl, whisk together the flour, granulated sugar, baking soda, salt, cinnamon, and pumpkin pie spice.
Mix until everything is evenly distributed and there are no large clumps.
Step 3: Add the Wet Ingredients
Add the pumpkin puree, vegetable oil, water, white vinegar, and vanilla extract to the dry ingredients.
Make sure you’re using plain pumpkin puree rather than pumpkin pie filling, which already contains added sugar and spices.
Step 4: Mix the Cake Batter
Stir gently with a whisk or wooden spoon until the batter is smooth and no dry flour remains.
Avoid overmixing, as this can make the finished cake less tender.
The batter should be thick but easy to spread.
Step 5: Transfer to the Baking Dish
Pour the pumpkin batter into your prepared baking dish.
Use a spatula to spread it evenly into the corners so the cake bakes uniformly.
Step 6: Bake the Cake
Place the dish in the preheated oven and bake for 30–35 minutes.
Check the center by inserting a toothpick. It should come out clean or with a few moist crumbs.
If wet batter sticks to the toothpick, continue baking for a few more minutes and check again.
Step 7: Cool Completely
Remove the cake from the oven and let it cool in the pan for 10–15 minutes.
Then allow it to cool completely before adding the frosting, approximately 45–60 minutes.
This step is important because frosting a warm cake can cause the cream cheese mixture to soften and slide.
Step 8: Prepare the Cream Cheese Frosting
In a large mixing bowl, beat the softened cream cheese and butter together with an electric mixer for about 2 minutes.
Continue mixing until the mixture is smooth, creamy, and free of lumps.
Step 9: Add the Powdered Sugar
Gradually add the powdered sugar, mixing on low speed until incorporated.
Add the vanilla extract and a pinch of salt.
Increase the mixer speed to medium and beat for another 2–3 minutes until the frosting is light, fluffy, and spreadable.
Step 10: Frost the Pumpkin Cake
Once the cake has cooled completely, spread the cream cheese frosting generously over the top.
Use an offset spatula or the back of a spoon to create soft decorative swirls.
Step 11: Chill and Serve
Refrigerate the frosted cake for 20–30 minutes to help the frosting firm up.
Cut into squares and serve chilled or slightly cool.
Enjoy every soft, spiced, creamy bite!
Expert Tips for the Best Pumpkin Wacky Cake
- Use pure pumpkin puree: Pumpkin pie filling contains added sugar and spices, which can change the recipe.
- Measure flour carefully: Too much flour can make the cake dense. Spoon it into your measuring cup and level the top.
- Don’t overmix: Stir only until the ingredients are combined for a tender crumb.
- Use room-temperature frosting ingredients: Softened cream cheese and butter blend together more smoothly.
- Cool completely before frosting: This prevents the frosting from melting.
- Taste the frosting: Add a little more powdered sugar if you prefer it sweeter.
- Check for doneness: Begin checking the cake around the 30-minute mark because oven temperatures can vary.
Delicious Variations
Pumpkin Spice Cake: Increase the pumpkin pie spice slightly for a stronger seasonal flavor.
Pecan Pumpkin Cake: Sprinkle chopped pecans over the frosting for a delicious crunch.
Maple Cream Cheese Frosting: Replace a little of the vanilla flavor with maple extract for a cozy maple twist.
Chocolate Chip Pumpkin Cake: Fold 1/2 cup of chocolate chips into the batter before baking.
Walnut Pumpkin Cake: Add chopped walnuts to the batter or sprinkle them over the frosting.
Cinnamon Cream Cheese Frosting: Add 1/2 teaspoon ground cinnamon to the frosting for extra warmth.
Mini Pumpkin Cake Squares: Bake the batter in a muffin pan for individual portions, adjusting the baking time and checking for doneness early.
What to Serve with Pumpkin Wacky Cake
This pumpkin cake is delicious on its own, but it pairs beautifully with a few simple extras.
Try serving it with:
- A cup of hot coffee
- Chai tea or black tea
- Warm apple cider
- Fresh pear or apple slices
- Chopped toasted pecans
- A light dusting of cinnamon
- A little extra cream cheese frosting
It’s especially lovely as part of a Thanksgiving dessert table.
How to Store Pumpkin Wacky Cake
Refrigerator: Because the cake has cream cheese frosting, cover it and refrigerate for up to 4 days.
Serving: Let individual slices sit at room temperature for about 10–15 minutes before serving if you prefer a softer cake and frosting.
Freezing: For best results, freeze the unfrosted cake. Wrap it tightly and freeze for up to 2 months. Thaw overnight in the refrigerator, then prepare and add fresh frosting.
Make Ahead: Bake the cake a day in advance, allow it to cool completely, and store it covered in the refrigerator. Prepare the frosting and spread it over the cake before serving.
Frequently Asked Questions
Why is it called Wacky Cake?
Wacky cake is inspired by a traditional cake recipe that uses unusual ingredient combinations and doesn’t require eggs or dairy in the batter. Vinegar and baking soda work together to help the cake rise.
Can I make this cake without eggs?
Yes! This cake recipe contains no eggs in the batter. The vinegar and baking soda help create its soft texture.
Can I use pumpkin pie filling instead of pumpkin puree?
It’s best to use plain pumpkin puree. Pumpkin pie filling already contains sweeteners and spices, which can change the flavor and texture.
Can I make this cake in a 9×13-inch pan?
Yes, but the cake will be thinner, so the baking time will be shorter. Start checking for doneness around 20–25 minutes.
Can I make the frosting ahead of time?
Absolutely. Prepare the frosting and refrigerate it in an airtight container. Let it soften slightly and beat briefly before spreading if needed.
Does this cake need to be refrigerated?
Yes. Since the topping contains cream cheese, keep the frosted cake covered in the refrigerator.
Can I use homemade pumpkin puree?
Yes! Homemade pumpkin puree works well as long as it’s smooth and not overly watery. If it contains excess liquid, drain it slightly before measuring.
How do I know when the cake is fully baked?
Insert a toothpick into the center. It should come out clean or with a few moist crumbs, rather than wet batter.
