Costco Sheet Cake Prices: 1‑Sheet vs 2‑Sheet Costs Explained

When you walk into the bakery aisle at your local warehouse club, the big, frosted rectangle on the display often sparks the biggest question: Costco sheet cake price. Knowing exactly how much a 1‑sheet or 2‑sheet cake costs can save you a surprise at checkout and help you plan for birthdays, anniversaries, or any excuse to celebrate.

Quick Takeaways

• As of October2025, a standard 1‑sheet cake at Costco typically runs between $19 and $22, while a 2‑sheet cake ranges from $38 to $45.
• Prices vary by region, frosting choice, and seasonal decorations (e.g., holidays can add $2‑$5 per sheet).
• Only Costco members can purchase, and the bakery accepts cash, credit, and Costco Anywhere Visa®.
• Custom designs (logo, themed toppers) start at an extra $5 per sheet.
• Pick‑up is free for members; delivery is available through third‑party partners in select metro areas.

Understanding the Basics: What Is a Sheet Cake?

Sheet cake is a flat, rectangular cake baked in a single layer pan, usually 9×13 inches for a 1‑sheet and 9×26 inches for a 2‑sheet. The design lets you serve many slices with minimal waste, making it a budget‑friendly choice for large groups.

The Costco bakery offers two standard sizes:

• 1‑sheet cake - feeds about 12‑15 people.
• 2‑sheet cake - feeds 24‑30 people.

Price Breakdown: 2025 Numbers

Costco keeps pricing simple, but a few variables can shift the final amount. Below is the typical cost you’ll see on the price board in most U.S. locations.

All prices are before tax. Sales tax varies by state, typically adding 5‑9% to the subtotal.

What Influences the Cost?

Beyond the base price, several factors can push the total up or down:

• Frosting type: Standard buttercream is included; specialty flavors like chocolate ganache or cream cheese carry a small surcharge.
• Decorations: Pre‑made holiday designs (e.g., pumpkins, snowflakes) are a flat fee per sheet. Custom toppers or edible images are billed per sheet as well.
• Location: West Coast warehouses often have a slightly higher base due to higher ingredient costs.
• Seasonality: Leading up to Christmas, Thanksgiving, or Valentine’s Day, expect a $2‑$5 premium for themed frosting and sprinkles.
• Membership level: Gold Star members pay the listed price; Executive members do not receive a discount on bakery items.

How to Order Your Costco Sheet Cake

The process is straightforward, but a few tips prevent missteps:

1. Check the Costco bakery display for the day’s fresh cakes. Prices are posted on a chalkboard.
2. Decide on size (1‑sheet or 2‑sheet) and frosting. If you want a special design, ask the staff for a price sheet.
3. Provide your membership number and the date you need the cake (same‑day pick‑up is possible if inventory permits).
4. Pay with cash, credit, or the Costco Anywhere Visa®. The receipt will list the base price, any add‑ons, and tax.
5. Pick up at the bakery counter during operating hours. If you’re using a third‑party delivery service, confirm the additional $5‑$10 fee.

Costco vs. Other Retailers: Is It Worth It?

When comparing sheet cake costs, consider both price and quality. Below is a quick snapshot against two common alternatives: Walmart bakery and local specialty shops.

Costco sits in the sweet spot: low base price, decent frosting variety, and optional custom work. If you need premium flavors or intricate designs, a boutique bakery may be worth the extra cost.

Tips to Keep Your Sheet Cake Budget Friendly

• Buy the cake a few days before your event to avoid holiday surcharges.
• Stick with the standard buttercream or vanilla frosting - it’s included in the base price.
• Use simple decorations like sprinkles instead of pre‑printed themes.
• Bring your own candles and toppers; Costco only charges for baked‑in designs.
• If you have an Executive membership, combine the cake purchase with other bulk items to maximize overall savings.
