Some cakes are good enough to bring to the table. This one might have folks asking for the recipe before they’ve finished their first slice.

This ultra-moist carrot cake is made with freshly grated carrots, crushed pineapple, and dark brown sugar for a deep, caramel-like flavor. It bakes in a half-sheet pan, then gets cut into four thin layers and stacked with chai cream cheese frosting. A generous sprinkle of chopped walnuts on top adds the finishing touch.
The chai frosting gets its flavor from Oregon Chai Original latte mix, which makes this cake taste like carrot cake met a cozy chai latte and decided to stay awhile.
Why You’ll Love This Carrot Cake
- Moist, tender crumb: Oil, carrots, and well-drained pineapple help keep the cake soft.
- Rich brown-sugar flavor: Dark brown sugar adds a deeper molasses note than light brown sugar.
- Chai-spiced frosting: Latte mix makes it easy to add sweet, warm chai flavor to classic cream cheese frosting.
- Beautiful layered look: One sheet cake becomes four layers, with frosting tucked between each one.
Tips for Making the Cake
Grate the carrots fresh. Freshly grated carrots are softer and more delicate than packaged shredded carrots, so they blend into the cake better.
Drain the pineapple well. Measure the crushed pineapple after draining so extra juice doesn’t weigh down the cake.
Mix the batter gently. Once the flour goes in, mix just until combined. Fold in the carrots and pineapple at the end.
Cool the cake completely. A fully cooled cake is easier to cut and stack. You can chill it briefly after cooling to make the pieces easier to handle.
Taste the frosting as you go. Oregon Chai Original is a sweetened latte mix. Start with half a packet, taste, then add more if you want stronger chai flavor. Add powdered sugar gradually until the frosting is thick enough to spread.

How to Assemble the Cake
After the cake has cooled, cut it into four equal rectangles, about 9×6½ inches each. Place one rectangle on your serving plate, spread frosting over it, then add the next cake layer. Repeat until all four layers are stacked. Frost the top, then finish with chopped walnuts.
Refrigerate the assembled cake for about 30 minutes before slicing. That gives the frosting time to set and helps the layers hold together.
Frequently Asked Questions
Can I use light brown sugar?
Yes. Light brown sugar will work, but dark brown sugar gives the cake a deeper molasses flavor. This recipe uses dark brown sugar.
Do I need to add nuts to the batter?
No. The chopped walnuts go on top as a garnish. You can leave them off or add more if you love a little crunch.
Can I bake this in a 9×13-inch pan?
This recipe is designed for a rimmed 13×18-inch half-sheet pan. The cake bakes into a thin sheet that can be cut into four layers. A 9×13-inch pan would make a thicker cake and won’t give you the same layers.

How should I store it?
Cover and refrigerate the cake because of the cream cheese frosting. Let slices sit at room temperature for about 15–20 minutes before serving for the softest texture.
