Dilini Jayathilaka2025-10-03Trustindex verifies that the original source of the review is Google. I recently taste her Rasmalai and Mango Lassi Cake pods from Blow a Candle, and it was absolutely amazing! That was incredibly delicious — soft, fresh, and full of flavour. What I love most is how reliable and friendly the service is. It’s clear that this business really values quality and customer satisfaction. Highly recommend Shubhra for anyone looking for cakes that taste just as good as they look. Perfect for birthdays, special occasions, or even just a sweet treat!

Thank you so much for accommodating my last-minute request for both of our 2-tier Wiggles cakes and creating two beautifully made cakes for my twins’ first birthday celebration. I truly appreciate your help in bringing my vision to life — both cakes turned out exactly how I imagined, and they were such a special part of the day. Thanks again!

I hope you will be more successful in the future!! sarena chan2025-09-26Trustindex verifies that the original source of the review is Google. I had the biscoff and it was heavenly! Not too sweet, very well balanced in texture and flavour, and really well presented! Sadia Khan2025-09-23Trustindex verifies that the original source of the review is Google. Their cake is one of the bests that I have ever tested! I tried their chocolate and tiramisu cake and both of them were mind blowing. The chocolate cake was very rich and the sweetness was perfect. Tiramisu was moist and flavoured to the perfection. Their cakes simply made my day and J literally regretted not buying some more! Not making that mistake next time 🥰 Rebecca O’Dare2025-09-04Trustindex verifies that the original source of the review is Google. Fantastic Service & Amazing Cupcakes! ⭐️⭐️⭐️⭐️⭐️ I ordered cupcakes as a surprise gift for my nephew while I was interstate, and the whole experience was absolutely seamless. The team made the ordering process so easy, even from afar, and I really appreciated the clear communication and friendly service. The cupcakes were beautifully presented and tasted amazing — my nephew loved them! It was such a thoughtful and hassle-free way to send a sweet surprise. Highly recommend and will definitely be using them again! Kaycy Biscocho2025-08-23Trustindex verifies that the original source of the review is Google.
