Oink 🐷 Baa 🐑 Moo! My little girl is 2! 💕

When I first started decorating custom cookie cakes and hand-painting event banners, it all began with a simple wish: to make the people I love feel extra special on their biggest days. Watching my own family's faces light up with custom themes and sweet treats inspired me to build Signature Sweets by Kate.

Now, I am so grateful to bring that same love, detail, and passion to my customers! Whether it's custom banner designs or delicious decorated cookie cakes, my goal is always to help make your special moments a little extra magical. ✨

✨ Vibrant colors, naturally! 🎨 Wholesome sweet treats are always the goal, which is why I love being able to offer dye-free food coloring options for my customers!

I recently tried out a new dye-free food coloring for this custom Minions cookie cake for William, and I am so thrilled with how amazing and vibrant these yellow and blue results turned out! 🌈 Check out the link in the comments if you'd like to see the natural food coloring used

What do you think of how these colors popped? Let me know in the comments! 👇

🍎 Class will soon be in session, and Mrs. Kane’s door is looking 10/10! 🚌✏️

Nothing gets us in the back-to-school spirit quite like custom hand-painted decor! It was such a joy painting this colorful door display to welcome her 2nd graders into a brand-new year of learning and fun. 🎨✨

To all the incredible teachers setting up their classrooms right now: you’re amazing! 🌟

You make a banana 🍌 cream pie with a cherry 🍒 on top!

Each time I make this pie it just gets better and better!

Welcome to Signature Sweet by Kate!

Hi, I’m Kate! I’m the baker, artist, and heart behind Signature Sweet by Kate, based right here in Ankeny, Iowa.

My passion is turning life’s special moments into unforgettable—and delicious—memories.

Whether I’m piping detailed buttercream icing, baking up custom cookie cakes, or hand-painting personalized event banners, I believe that every celebration deserves a uniquely custom touch.

What I Do
Custom Cookie Cakes & Sweet Treats: Handcrafted, freshly baked desserts designed specifically to match your party vision, theme, or favorite flavor.

Hand-Painted Banners & Signage:
Custom, keepsake-quality banners created to pair perfectly with your dessert display and event decor.

Beyond the Bakery
When I’m not in the kitchen covered in flour or mixing custom icing colors, I’m usually spending time with my family, tending to my backyard vegetable garden, hosting gatherings with neighbors and friends, golfing, or relaxing with a great novel.

I love helping our community celebrate life’s milestones—big and small. Thank you for letting me be a sweet part of your story!
