¾ cup vegetable oil: Keeps the cake moist and tender.
¾ cup sour cream (room temperature): A secret ingredient for added moisture and richness.
4 large eggs (room temperature): Essential for structure and to help the cake rise.
½ cup whole milk: Helps achieve the perfect batter consistency.

How to Make Biscoff Honey Bun Cake

Warm the Cookie Butter: Begin by warming the ⅓ cup of Biscoff cookie butter until it’s drizzly but not too liquidy; this makes it easier to mix.
Mix Crumble Topping: In a medium bowl, combine the warmed cookie butter, ⅓ cup of light brown sugar, coarsely crushed Biscoff cookies, 1 ½ tablespoons melted salted butter, and 1 teaspoon cinnamon. Mix until the texture resembles wet sand and set aside.
Preheat Your Oven: Preheat your oven to 350°F (180°C) and grease a 9×13 inch baking dish with nonstick baking spray to prevent sticking.
Prepare the Cake Batter: In a large mixing bowl, whisk together the yellow cake mix, ¾ cup vegetable oil, ¾ cup sour cream, 4 large eggs, ½ cup whole milk, and 1 teaspoon vanilla extract until everything is well combined and smooth.
Assemble the Cake: Pour half of the cake batter into the prepared dish, smoothing it out with a spatula. Spread the crumble mixture evenly over the batter, then pour the remaining cake batter on top, smoothing it out again.
Bake the Cake: Place the assembled cake into the preheated oven and bake for 35-40 minutes. It’s done when a toothpick inserted into the center comes out mostly clean with just a few crumbs attached.
Prepare the Glaze: While the cake is baking, melt 2 tablespoons of salted butter in a small, light-colored saucepan over medium heat. Stir frequently for 3-5 minutes, until it turns a golden amber color and emits a nutty aroma. Immediately transfer it to a heat-safe bowl and let it cool slightly.
Make the Glaze: Once the cake is nearly finished baking, whisk together the 1 ½ cups powdered sugar, melted browned butter, 2 tablespoons melted Biscoff cookie butter, 1 teaspoon vanilla extract, 1-2 tablespoons milk, and a pinch of salt until smooth.
Glaze the Cake: As soon as the cake comes out of the oven, pour the glaze evenly over the top, spreading it to the edges with a spatula. Immediately sprinkle crushed Biscoff cookies on top so they adhere.
Let it Set: Allow the cake to sit for about 20 minutes, then slice and serve warm.

Storing & Reheating

To store any leftovers, simply place the Biscoff Honey Bun Cake in an airtight container at room temperature for up to 2 days. If you want to keep it longer, refrigerate it for about a week. For those moments when you want to savor it later, you can freeze individual slices wrapped tightly in plastic wrap and stored in a freezer-safe bag for up to 3 months. When ready to enjoy, reheat in the microwave for 15-20 seconds just until warm, but be mindful that the texture might soften slightly; a sprinkle of crushed cookies on top can refresh it beautifully.

Chef’s Helpful Tips

Make sure your eggs and sour cream are at room temperature; they mix better, resulting in a fluffier cake.
Don’t skip the cinnamon in the crumble—it adds essential warmth and brings everything together.
For the perfect drizzle, adjust the milk in the glaze to reach your desired consistency; it should be pourable but not too runny.
Keep an eye on the cake during the last few minutes of baking; if the edges caramelize too much, covering it loosely with foil can help.

Whether you’re trying to impress guests or simply treat yourself, this Biscoff Honey Bun Cake will not disappoint. With its addictive flavors and scrumptious textures, it has all the makings of a family favorite. Don’t hesitate to play with the ingredients a bit—maybe add some nuts or experiment with different kinds of cookie butter! Embrace the joy of baking, and enjoy every delightful bite.

Recipe FAQs

Can I use another type of cake mix?

Absolutely! You can substitute the yellow cake mix for a vanilla or even chocolate cake mix if you’re feeling adventurous. Adjustments may be needed for cooking times based on the type you’re using.

How do I know if the cake is fully baked?

You want to look for a toothpick inserted into the center that comes out mostly clean or with just a few moist crumbs clinging to it. The edges should look slightly golden, signaling that it’s perfect.

Can I make this cake ahead of time?

Yes, this cake keeps well! You can bake it a day or two in advance; just store it covered at room temperature. The flavors often deepen as it sits, enhancing the overall taste.

What should I do if the glaze is too thick?

If your glaze ends up a little too thick, simply whisk in additional milk a teaspoon at a time until you reach your desired consistency. This way, it will drizzle beautifully over your cake without clumping!
