  • Serves Port Costa, CA

Hi, I’m Bailie — the baker, buttercream artist, and detail enthusiast behind the cakes. I specialize in handcrafted wedding and micro-wedding cakes that taste just as incredible as they look. From silky Swiss meringue buttercream to thoughtfully paired fillings and flavors, every cake is made from scratch with quality ingredients and a whole lot of heart. Whether you’re envisioning a classic white tier adorned with delicate florals or something modern and playful, I work closely with couples to create a cake that feels personal, elevated, and completely unforgettable. Because your cake shouldn’t just be dessert — it should be a moment. 🤍

Thyme and Finch Bakery made our wedding day even more unforgettable! Our cake was absolutely stunning — elegant, beautifully detailed, and perfectly matched our vision. But beyond the looks, the flavor was incredible. Every single guest raved about how moist and delicious it was (we barely had leftovers!). The entire process was seamless, professional, and stress-free. If you’re looking for a wedding cake that tastes just as amazing as it looks, Thyme and Finch is it.

I’m a Cake Decorators. A world without custom cakes would lack sweetness and celebration, as each creation brings joy, love, and artistry to life’s most special moments. My cake designs blend elegance and creativity, inspired by the beauty of celebrations and the joy of each occasion. I use color, texture, and unique themes to bring your vision to life, making every wedding and birthday unforgettable.

Working with LiliRose Bakery for our wedding cake was truly exceptional. From the first conversation, they were attentive, patient, and eager to bring our vision to life. We shared a few inspiration photos, and they beautifully transformed the idea into a luxury cake beyond anything we imagined. The design was elegant, clean, and refined — every detail looked flawless. It wasn’t just a cake, it was a centerpiece that had all our guests talking and taking photos before even tasting it! And the flavor… incredible. Moist, rich, and perfectly balanced — you could immediately taste the quality and craftsmanship. Many of our guests came back for a second slice and asked where we ordered it from. The delivery was on time, professional, and stress-free, which really matters on a wedding day. What stood out the most was their passion and the care they put into every step. LiliRose Bakery made us feel valued, heard, and taken care of. We highly recommend them to any couple who wants a luxurious, delicious cake that looks as breathtaking as it tastes. We couldn’t be happier with our experience. Thank you for adding something so beautiful and memorable to our special day.

Sf Candy Bar 
Rating: 5.0 (3 reviews)
  • Serves Port Costa, CA

When I opened SF Candy Bar in 2012, the business was busy from the start. In 2012, the economy was just coming out of a recession and Silicon Valley started to attract top talent from all over the world. Experiential add on features, like our candy buffets, was fun at office parties, trade shows and holiday parties. Brides and Mitzvahs also found so much joy in our services. Fast forward to more than a decade later, we have added on more services from popcorn buffets, custom packaged party favors, and trail mix buffets. SF Candy Bar is dedicated to providing stunning buffet designs to guests at special events.

We recently had SF Candy Bar cater a popcorn buffet at our event, and it was a huge success! The setup was stylish and well-organized, with an impressive variety of popcorn flavors that appealed to everyone. From classic buttered and caramel to more unique options like white cheddar and spicy sriracha, the selection was both fun and flavorful. The popcorn was fresh and perfectly seasoned, with each flavor offering a deliciously satisfying crunch. The presentation was eye-catching, with decorative jars and scoops that added a charming touch to the buffet. The SF Candy Bar team was professional and attentive, ensuring the buffet remained fully stocked and inviting throughout the event. The popcorn buffet was a standout feature that guests couldn't stop talking about. SF Candy Bar made it a delightful and memorable experience.
