On a Saturday morning, people were lined up out the door! I have great respect for the lovely lady that was handling this crowd by herself. She kept the line moving and never stopped smiling. A prefect example of grace under pressure! Everything about this cafe shows the owner’s love and creativity. (Even the straws are heart-shaped!) My pulse started racing when I saw all the gorgeous offerings in the display case, and it was torture trying to decide. I got the Chocolate Strawberry Cupcake and an Iced Americano. There were several tables available, but I opted for a comfy stool at the window bar. You can’t imagine my delight, when I bit into that cupcake and realized that in addition to the strawberry frosting, it was filled with strawberry jam! Now that’s GOURMET! The iced espresso beverage was also high quality and delicious. I had a ball admiring their cute and clever decor, which is extremely photogenic! And as a person of faith, I appreciate how they honor Jesus. Mahalo! I will be back very soon!

Cupcakes Boom has by FAR the BEST tasting cupcakes on the island! the staff is so kind and the owner was super helpful. We tasted ALL their cupcakes in hopes to make a last minute order for our wedding. Every single cupcake was amazing but the sticky mango rice cupcake could end wars. It is delicious!! They were able to make our wedding cake and dozens of cupcakes 2 days before our wedding! Such an amazing experience, I love y’all!!

We went looking for a birthday dessert for my daughter. Delicious cupcakes. We tried the peanut butter cup, chocolate, strawberry, and lilikoi. Lilikoi was a definite stand out. Sweet and tangy!

We love visiting Cupcakes Boom for all special occasions, or even just a fun day out in Hilo! Their macarons are incredible, and duh… the cupcakes My daughter is obsessed with the Strawberry cupcake, and I always go for the lilikoi, it’s SO good.
Not only is the quality top-notch, but the customer service is wonderful. You’re always greeted with genuine Aloha and a big smile. We absolutely adore Nikki, the founder, she’s uplifting, fun, and such a joy to be around.
Highly recommend starting (or ending!) your day with a special treat from Cupcakes Boom ✨

I usually do delivery instead of pickup. With delivery, I don’t think there are as much options as pickup. I would also like to see sugar free options for those who are trying to control their sugar. Other than that, I think the food is phenomenal. The croissant is flaky and a little crunchy on the outside. The cinnamon roll is also very tasty and the lilikoi cupcake makes me forget my name and address (LOL). Just YUMMY!!!

This shop is such a blessing! Every dessert I have tried has been absolutely delicious—visually appealing, flavorful, and made with so much care. You can truly taste the love in each bite. I also love that this is a faith-based business, grounded in God and sharing His light through something as sweet as cupcakes and other treats. The atmosphere was joyful and welcoming, and I’m so grateful to support a shop that honors God while serving the community so beautifully. I will definitely be back!
