Ingredients for biscoff bundt cake recipe with box cake mix
Just 14 ingredients transform box mix into restaurant-quality Bundt cake magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Boxed Vanilla Cake Mix 🍰 | 1 box | Any brand, vanilla flavor |
| Unsalted Butter 🧈 | ½ cup | Softened, not melted |
| Large Eggs 🥚 | 2 whole | Room temperature preferred |
| Sour Cream 🥛 | ½ cup | Full-fat for best moisture |
| Milk 🥛 | ½ cup | Whole milk preferred |
| Vanilla Pudding Mix 🍦 | 3 tbsp | Instant, vanilla flavor |
| Granulated Sugar 🍚 | ¼ cup | Extra for swirl effect |
| Vegetable Oil 🫒 | ¼ cup | For Bundt pan greasing |
| All-Purpose Flour 🌾 | ¼ cup | For dusting Bundt pan |
| Vanilla Extract 🌿 | 1 tsp | Pure, for extra flavor |
| Baking Powder 🍞 | ½ tsp | Extra for lift |
| Powdered Sugar 🍚 | 1 cup | For optional glaze |
| Heavy Cream 🥛 | ¼ cup | For optional glaze |
| Lemon Juice 🍋 | 1 tsp | For glaze tang |
The box mix is your base, but don't skimp on the good stuff. Betty Crocker or Duncan Hines work great—I've tested both. The sour cream is non-negotiable for moisture (the full-fat kind, not low-fat). For the butter, Land O'Lakes or Plugrá are reliable, but any brand works if it's softened. Grab vanilla pudding mix from the baking aisle—Jell-O or Betty Crocker are my go-tos. Pro tip: Check the box mix for baking powder already included before adding extra—some brands have it, some don't. If you're unsure, just add it anyway; it won't hurt.
No sour cream? Plain Greek yogurt at half the amount works in a pinch. Butter too hard to soften? Microwave it for 20 seconds. The vanilla pudding mix can be swapped for 3 tbsp instant vanilla pudding powder if that's what you've got. For the glaze, powdered sugar isn't optional—it's what gives that professional finish. Short on heavy cream? Whipped topping from a can makes a decent substitute. The lemon juice is key for the glaze's tang—fresh is best, but bottled works too. And if you're feeling fancy, add a pinch of salt to the glaze for balance.
This cake keeps beautifully for 4 days at room temperature, wrapped in foil. For longer storage, slice and freeze portions for up to 3 months. I always make a double batch—one for guests, one for me to enjoy over the next week. The glaze sets quickly, so assemble it right before serving. If you're not using it all, store the extra powdered sugar in an airtight container with a slice of bread to keep it fresh. The Bundt pan? Grease it well—I use a mix of oil and flour, then tap out the excess. Don't skip this step, or you'll have cake sticking everywhere.

Step-by-step instructions for Biscoff Bundt cake with box cake mix
Here's how to transform basic cake mix into a showstopping Bundt cake with that signature swirl.
Prepare the Bundt Pan and Mix the Cake Batter
Begin by greasing the Bundt pan thoroughly with the 0.25 cup vegetable oil, using a pastry brush to coat all surfaces and crevices. Then dust it evenly with the 0.25 cup all-purpose flour, tapping out any excess. This ensures easy release later. In a large mixing bowl, combine the 1 box boxed vanilla cake mix, 0.5 cup unsalted butter, 2 whole large eggs, 0.5 cup sour cream, 0.5 cup milk, 3 tbsp vanilla pudding mix, and 0.5 tsp baking powder. Mix on medium speed for 2 minutes until smooth and fully incorporated.
Here's the thing—using full-fat sour cream and whole milk makes this cake incredibly moist. The pudding mix adds that extra vanilla boost while keeping the texture tender. Make sure your butter is softened but not melted, or the batter will be too thin and runny.
Create the Vanilla Swirl and Pour into the Pan
In a small bowl, whisk together the 0.25 cup granulated sugar and 1 tsp vanilla extract. This creates the sweet swirl that makes this cake special. Pour half of the batter into the prepared Bundt pan. Then, using a spoon or small ladle, drizzle the vanilla sugar mixture in a zigzag pattern over the batter. Finally, add the remaining batter on top, gently swirling with a knife to create marbled patterns.
Don't worry if it's not perfect—the swirl will still look beautiful after baking. The key is to distribute the vanilla mixture evenly throughout the batter. If you're feeling fancy, you can even pipe the vanilla mixture through a small star tip for more intricate designs.
Bake to Golden Perfection
Preheat your oven to 350°F and place the Bundt pan inside. Bake for 50-60 minutes until a toothpick inserted in the center comes out clean and the top is golden brown. The cake is done when it springs back slightly when touched and the edges pull away from the pan.
I know it seems like a long time, but patience is key here. The cake needs that full baking time to develop its signature moist texture. If you check it too early, you'll end up with a cake that's still gooey in the center. Let it bake until it passes the toothpick test—this guarantees a perfectly baked cake every time.
Cool and Glaze (Optional)
Remove the cake from the oven and let it cool in the pan for 10 minutes. Then carefully invert it onto a wire rack to cool completely. For the glaze, whisk together the 1 cup powdered sugar, 0.25 cup heavy cream, and 1 tsp lemon juice until smooth. Drizzle the glaze over the cooled cake and let it set for 10 minutes before serving.
The lemon juice in the glaze adds a subtle tang that balances the sweetness. If you prefer a richer glaze, you can reduce the lemon juice to ½ tsp or omit it entirely. The cake will taste amazing either way, but the glaze really makes it special for any occasion.
Pro Tips For Making Biscoff Bundt Cake Recipe With Box Cake Mix
- Grease That Bundt Well: I learned this the hard way—skipping the extra grease step leads to a cake that sticks like glue. Use a mix of melted butter and flour (about 2 tablespoons butter + 1 tablespoon flour) to coat the Bundt pan thoroughly, then tap out any excess. This isn’t just about release; it’s about a clean slice every time.
- Use Room-Temp Eggs: Cold eggs from the fridge will curdle the batter, and nobody wants a lumpy Bundt cake. Let your eggs sit out for 30 minutes before cracking them into the mix—this keeps the sour cream and butter from separating and ensures a smoother texture. (Yes, even if you’re impatient like me.)
- Don’t Overmix the Batter: After adding the eggs and sour cream, mix just until combined—no need to go full speed. Overmixing develops gluten and turns your cake into a dense brick. A few swirls with a spatula is all it takes. Trust the process; your future self will thank you for not overdoing it.
- Bake Until the Center Springs: The box mix might say "30-35 minutes," but don’t pull it out until a toothpick comes out clean—or at least with just a few crumbs. A slightly underbaked Bundt cake will keep sinking in the middle as it cools. If unsure, add 5 more minutes; better to wait than deal with a gummy center.
Essential equipment for this dish
Bundt Pan Essentials
First things first—you'll need a 10-12 cup Bundt pan with a non-stick coating or one that's well-seasoned. I recommend Wilton's non-stick Bundt pans for beginners—they release beautifully without sticking. If you're on a budget, Cuisinart's stainless steel Bundt pan works too, but you'll need to grease it extra well.
The key is finding a pan with tall, intricate sides for that classic Bundt cake look. 🍰
Mixing Tools
For the batter, grab a large mixing bowl (I use Pyrex glass bowls—they're sturdy and easy to clean) and a hand mixer or stand mixer. A spatula comes in handy for scraping down the sides.
For the vanilla swirl, a small whisk bowl and a small offset spatula help create those elegant zigzag patterns. Pro tip: Use a measuring cup with a pour spout—it makes pouring the batter into the pan mess-free.
Greasing Supplies
Greasing your Bundt pan properly is non-negotiable. You'll need vegetable oil (like Crisco) and all-purpose flour. I also keep a pastry brush handy for coating hard-to-reach crevices. Some bakers swear by Bundt pan release spray, but I find the oil-and-flour method works best for me. Just
Optional Glazing Tools
For the optional glaze, you'll need a small bowl and a whisk to combine the powdered sugar, heavy cream, and lemon juice. A fine-mesh strainer helps remove any lumps for a silky-smooth finish. If you're feeling fancy, add a piping bag with a small round tip to create elegant drizzle patterns. For serving, a cake stand or large platter elevates the presentation—no need for anything fancy, just something sturdy.
Testing Doneness
You'll want a toothpick or skewer to test for doneness. I also keep a small plate nearby to catch any drips when inverting the hot pan. A wire cooling rack is essential for letting the cake cool completely before glazing.
And don't forget a timer—Bundt cakes bake longer than you think! Set it for 50-60 minutes and check at the lower end of that range. ⏰
Storage Containers
For leftovers, store cake slices in an airtight container with parchment paper between layers to keep them moist. If freezing, use quart-sized freezer bags with the air squeezed out. Label them with the date—this cake keeps well for 3 months in the freezer.
For the glaze ingredients, keep powdered sugar in an airtight container with a slice of bread to absorb moisture. 🥫

Frequently asked questions
Why does this recipe use sour cream instead of regular milk?
Sour cream adds unmatched moisture and tenderness to the cake that regular milk can't match. The fat content in full-fat sour cream creates a richer texture while keeping the crumb soft for days. Plus, it helps balance the sweetness of the box mix for a more sophisticated flavor.
Can I make this cake without a Bundt pan?
Yes! Use a 9-inch round cake pan or even a loaf pan for a different shape. The vanilla swirl technique still works—just pour half the batter, add the vanilla mixture, then top with remaining batter. Bake for 30-35 minutes at 350°F instead. The texture will be identical, just the presentation changes.
What if my cake comes out dry or crumbly?
This usually happens if the cake bakes too long or the oven runs hot. Check for doneness at 50 minutes—the center should be just set (no wet batter but not completely dry). For extra moisture, brush warm slices with simple syrup (equal parts sugar and water, heated until dissolved) before serving. Also ensure your butter is softened, not melted.
Can I substitute the vanilla pudding mix with something else?
Use 3 tbsp instant vanilla pudding powder (same as the mix) or 1 tbsp vanilla extract mixed with 2 tbsp granulated sugar. For a different flavor twist, try chocolate pudding mix or even instant coffee mix (½ tbsp) for a mocha variation. Just adjust the sugar to taste.
How do I fix a cake that stuck to the pan?
Run a hot knife around the edges to loosen it, then invert onto a plate. If it tears, carefully pull it apart—it'll still taste great! Next time, grease with shortening or butter instead of oil, or use a Bundt pan release spray. For stubborn cases, place the pan in the freezer for 10 minutes to help release the cake.
