Tips for Baking and Serving Sheet Cakes

- Even Baking: Use a shallow pan for a flat top, ideal for decorating.
- Cooling: Allow the cake to cool completely before frosting.
- Ice Cream Pairing: For something extra special, serve birthday cakes with ice cream. Its the perfect party treat!
- Storage: Store leftover cake in an airtight container at room temperature or in the refrigerator based on the type of frosting.
Packaging Ideas for Sheet Cakes
Once your cake is baked and frosted, it’s time to think about presentation and packaging. Here are some options for transporting and displaying your sheet cakes:
- Cake Boxes with Windows: Great for showcasing the cake at events.
- Disposable Aluminum Pans with Lids: Convenient for transporting and serving.
- Cake Carriers: Secure and stylish transport.
- Custom Packaging: Add a personal touch for special events with custom cake boxes.
- Cake Bags: Durable bags with handles are perfect for carrying.
Pro Tip: Choose packaging that keeps the cake stable and fresh until it reaches its destination.
How to Slice Your Sheet Cake for Any Occasion
The size of each slice can vary significantly depending on the standard sizes of the sheet cake and the number of guests you’re serving. Here’s a quick guide to help you decide:
- 2-inch slices are ideal for most events, providing a balanced portion for individual slices.
- For smaller gatherings, consider larger slices to give guests a more generous portion.
- For bigger events, opt for smaller pieces to ensure there’s enough cake for everyone.
- Cake height matters! Taller cakes make even smaller pieces feel satisfying, while shorter cakes may call for larger pieces to have a similar impact.
Aim for consistent individual slices to keep the presentation neat and portions even for all guests.

Q: What are sheet pan extenders, and when should I use them?

Do you have a measurement list of how much of everything for each sheet cake? Full, half and quarter? I am starting a baking business out of my house, I have been baking for a long time but this time I am making cakes from scratch instead of out of the box. I will be doing tier cakes and sheet cakes but I just am not sure of how much to use for each.

How many minutes would you bake the 12x16 sheet cake
Melissa says
I was wondering how long you would bake the 1/2 sheet cake for? Ive made tons of rounds but not sure about this!! Thanks
Better Baker says
For a 1/2 sheet cake, you'll typically want to bake it at 325°F to 350°F (160°C to 175°C) for about 25 to 30 minutes, but the exact time can vary depending on your oven and the recipe. I recommend checking for doneness by inserting a toothpick into the center—if it comes out clean or with a few crumbs, your cake is ready! Happy baking! 🍰
