You might even catch us at local farmers' markets or festivals, so keep an eye out!
Do You Only Sell Flan?
Not even close! While flan and flancocho are our staple products, we have a galaxy of desserts waiting for you.

You’ll find our Mini Dessert Collection, Individual Dessert Collection, and Voluminous Dessert Collection—perfect for any sweet tooth! Swing by our collections page to explore all the mouthwatering exhibits we have to offer.
What’s an Exhibit?
Every exhibit is a celebration of a specific dessert type—like our fabulous Flan Exhibit! Within each exhibit, you’ll discover all the delicious flavor varieties of that dessert. Ready to dive deeper? Check out our exhibits page for the full scoop!

Frequntly asked questions about Ordering and Payment

How far in advance should I order my wonders?
To give our dessert lab the time it needs to work its magic, we suggest placing orders at least 7-10 days in advance for creations under $100—because even flans require time to set! If your order falls between $100 and $300, aim for 2-4 weeks ahead. For events exceeding $300, it's best to book up to 3 months in advance. Remember, it’s first-come, first-served, so get your orders in early!
What is the price range for ordering my wonders?
Our pricing varies based on the delightful creation:

Mini Desserts: Starting at $15 per dozen.

Individual Desserts: Starting at $30.

6-inch Cakes: Starting at $20, while 10-
inch rounds start at $35. Specialty decorations may incur additional charges.
Is a deposit required for my order?
Absolutely! A 50% deposit is needed to confirm your order, with the remaining balance due upon pickup or delivery.
What if I need to cancel my order?
Life happens, and we get it! If you find yourself needing to cancel your order, here’s how it works at The Big Flan Theory:


Cancelling 72 Hours in Advance: If you cancel at least 72 hours before your scheduled pickup or delivery, we’ll give you store credit for your deposit, valid for one year. You can use this credit for future orders within six months.

Cancelling Less Than 72 Hours Before: If you cancel within 72 hours, we’ll have to keep your deposit—sorry, but no sweet surprises here!

Last-Minute Changes: If you need to cancel within 24 hours of placing your order and it’s not due for at least 72 hours, we’ll refund your deposit in full. Refunds take about 7-10 business days to process.

Need to Adjust Your Order? Just let us know as soon as possible! We’ll do our best to accommodate any changes, but additional charges may apply.

No-Shows & Cancellations Within 24 Hours: If you don’t show up or cancel within 24 hours, we’ll have to keep your deposit.

What if I need a last-minute dessert?
We get it—sometimes dessert cravings (or last-minute party needs) sneak up on you! While we recommend ordering in advance, we may be able to accommodate last-minute orders based on availability. Heads up: last-minute requests need full payment upfront, so reach out ASAP and we’ll do everything we can to save the day with some flan-tastic goodness.
