How to Make Pumpkin Marshmallow Sheet Cake

1. Preheat the oven to 350°F (175°C) and prepare a 9×13-inch baking pan by spraying it lightly with cooking spray for easy release.

2. Mix the dry ingredients by whisking together all-purpose flour, sugar, pumpkin pie spice, baking soda, and salt in a medium bowl until evenly combined.

3. Combine the wet ingredients in a large bowl by mixing oil, pumpkin puree, and eggs until well blended. Gradually fold in the dry mixture until you achieve a mostly smooth batter.

4. Pour the batter into the prepared pan, spreading it out evenly to the edges. Bake in the preheated oven for 40-45 minutes, or until a toothpick inserted in the center comes out clean. Allow the cake to cool for at least 30 minutes.

5. Prepare the frosting by combining egg whites, sugar, and cream of tartar in a heatproof bowl over simmering water. Whisk until the mixture is warm and smooth, about 2-3 minutes.

6. Beat the egg mixture using a stand mixer until stiff peaks form, taking about 6-8 minutes to reach the desired texture.

7. Frost the cooled cake evenly with the fluffy egg white mixture. If you like, broil the frosting for a few seconds until golden brown while keeping a close watch to prevent burning. Alternatively, use a kitchen torch for toasting.

Optional: Top with mini marshmallows for an extra touch of sweetness and texture.

Pumpkin Marshmallow Sheet Cake Recipe FAQs

What type of pumpkin should I use?
Absolutely! You can use either canned pumpkin puree or freshly made pumpkin puree. If using fresh, simply roast a small sugar pumpkin until soft, scoop out the flesh, and blend until smooth. Canned pumpkin puree is a convenient option and works perfectly for this recipe.

How should I store leftover Pumpkin Marshmallow Sheet Cake?
Store your cake in an airtight container in the fridge for up to a week. It will even get more flavorful as it sits! For room temperature storage, cover it with a clean kitchen towel for up to 2 days to maintain moisture and freshness.

Can I freeze Pumpkin Marshmallow Sheet Cake?
Yes! To freeze, first allow the cake to cool completely. Then, wrap individual slices tightly in plastic wrap, followed by aluminum foil to prevent freezer burn. This will keep them fresh for up to 3 months. When you’re ready to enjoy, thaw them overnight in the fridge.

What if my frosting isn t setting properly?
If your frosting isn’t reaching stiff peaks, ensure that your egg whites are at room temperature and that the bowl and whisk are free from any grease. It helps to add a pinch of salt and make sure you re beating the mixture long enough (6-8 minutes). If you’re still struggling, consider whipping in a bit more cream of tartar for stabilization.

Can I make this cake vegan-friendly?
Very! Substitute the eggs with flax eggs (1 tablespoon of ground flaxseed mixed with 3 tablespoons of water for each egg), and use aquafaba instead of egg whites for the frosting. Make sure that your sugar is vegan-friendly as well, as some sugar is processed with bone char. Your Pumpkin Marshmallow Sheet Cake will still be a hit without animal products!

How can I tell when my cake is done baking?
The best way to check if your cake is done is to insert a toothpick into the center. If it comes out clean or with just a few moist crumbs, it s ready! Remember to check it around the 40-minute mark, as baking times can vary slightly based on your oven.
