There's something magical about a freshly baked cinnamon loaf cake. The warm spice, the moist crumb, and that sweet frosting on top: pure comfort in every slice. But this version takes it a step further.

Inspired by the Dutch holiday Sinterklaas, this loaf cake is finished with crushed speculaas cookies, giving it a crunchy, spiced topping that makes it stand out from your average cinnamon cake.
If you've never tried speculaas before, think of them as spiced shortcrust cookies - similar to Biscoff cookies - that are beloved in the Netherlands. Their flavor comes from a fragrant mix of cinnamon, nutmeg, cloves, and cardamom, which perfectly complements the cozy cinnamon base of this loaf cake.
What is Sinterklaas?
In the Netherlands, Sinterklaas is celebrated on December 5th, and it's one of the most beloved holidays of the year. Children leave out their shoes for small gifts, songs are sung, and the holiday is filled with traditional treats. Among them are speculaas cookies. This cinnamon loaf cake with speculaas topping is my twist on that tradition, bringing a little Dutch holiday cheer into an American kitchen. See al my Dutch recipes here.

Ingredient Breakdown
Here's a closer look at what makes this cake work:
- Butter - Creates a tender, moist crumb.
- Brown sugar - Adds sweetness and depth of flavor with its subtle molasses notes.
- Syrup (light corn syrup or golden syrup) - Gives the batter extra moisture and enhances the sweetness.
