Desserts
America's Test Kitchen apple bundt cake delivers the perfect balance of moist vanilla layers topped with a fragrant spiced streusel crown—every slice reveals tender crumb and caramelized apple notes. This recipe transforms a classic dessert into a showstopper with precision measurements and baking techniques that ensure consistent results. The secret lies in proper mixing and baking times, which prevent dryness while developing rich apple flavor through the streusel.
What sets this bundt cake apart is the foolproof method that guarantees a moist interior with a crisp, caramelized exterior. We use a combination of butter and oil for richness, while brown sugar in the streusel adds depth.
The cake bakes at a precise 350°F for 50-60 minutes, allowing the apples to soften without losing their shape, and the streusel to develop a golden, crunchy texture.
The result is a perfectly proportioned bundt cake with a tender crumb that stays moist for days, thanks to the buttermilk in the batter. The streusel crown becomes a fragrant, caramelized topping that contrasts beautifully with the vanilla cake.
This is the kind of dessert that impresses guests while being simple enough for weeknight baking—no special equipment required beyond a bundt pan.
Once baked, the cake is finished with a light vanilla glaze that adds shine and sweetness without overwhelming the apple flavor. Serve warm with vanilla ice cream or whipped cream for the ultimate comfort dessert. The precision of this recipe ensures you'll achieve bakery-quality results every time.

Precision ingredients for a bakery-quality bundt cake with caramelized streusel crown.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for streusel |
| Granulated Sugar 🍚 | 1 ½ cups | For cake batter |
| Light Brown Sugar 🍚 | ½ cup | Packed, for streusel |
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted, spooned and leveled |
| Baking Powder 🧂 | 2 tsp | Aluminum-free preferred |
| Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Vanilla Extract 🍯 | 2 tsp | Pure Madagascar bourbon |
| Buttermilk 🥛 | 1 ½ cups | Cold, full-fat preferred |
| Large Eggs 🥚 | 3 whole | Room temperature |
| Vegetable Oil 🫒 | ½ cup | Light, neutral flavor |
| Granny Smith Apples 🍎 | 4 medium | Peeled, cored, sliced |
| Old-Fashioned Rolled Oats 🌾 | 1 cup | Blended into flour |
| Ground Cinnamon 🌿 | 1 ½ tsp | Freshly ground preferred |
| Ground Nutmeg 🌿 | ½ tsp | Freshly grated |
| Ground Ginger 🌿 | ½ tsp | Freshly ground |

| Milk 🥛 | ¼ cup | For glaze |
The apples are non-negotiable—Granny Smiths hold their shape while baking, preventing a mushy center. Organic apples from Whole Foods or your local farmers market have the best flavor. Peel and slice them uniformly (about 1/4-inch thick) for even cooking. The oats in the streusel should be old-fashioned, not quick—they create a chewier texture. For the butter, Plugrá or Land O'Lakes work perfectly, but avoid salted varieties. The buttermilk must be cold to prevent curdling when mixed with the eggs.
No Granny Smiths? Fuji or Honeycrisp work in a pinch, but they soften faster. Substitute the oats with crushed graham crackers for a sweeter streusel. The vanilla extract is critical—Madagascar bourbon offers the richest flavor, but pure vanilla will suffice. For a dairy-free version, use unsweetened almond milk instead of buttermilk and vegan butter. The baking powder must be fresh; if it's over six months old, replace it entirely. The glaze powder can be homemade (powdered sugar + vanilla) or store-bought like Betty Crocker.
Store the cake at room temperature in an airtight container for up to 3 days—the streusel stays crisp for longer than you'd expect. For extended storage, freeze the baked cake (without glaze) for up to 3 months. Reheat slices at 350°F for 5 minutes to restore the streusel's crunch. The glaze should be applied immediately after baking to prevent drying. If making ahead, bake the cake without the streusel, store it wrapped, then add the streusel and glaze just before serving.

Step-by-step instructions for america's Test Kitchen apple bundt cake
Master the perfect balance of tender vanilla cake and spiced apple streusel with these precise techniques.
Prepare the Cake Batter for Optimal Texture
In a large mixing bowl, combine the 1.5 cups granulated sugar and 3 whole large eggs at room temperature. Beat on medium speed for 3-4 minutes until the mixture is pale yellow and thickened. This step incorporates air, which is crucial for that light, airy texture we're after.
In a separate bowl, whisk together the 2.5 cups all-purpose flour, 2 teaspoons baking powder, and 0.5 teaspoon salt. Gradually add this dry mixture to the egg-sugar mixture while mixing on low speed. Add the 0.5 cup vegetable oil and 2 teaspoons vanilla extract, mixing just until combined. The batter should be smooth but not overly thick.
Finally, stir in the 1.5 cups cold buttermilk until just combined. Avoid overmixing—stop as soon as the flour is incorporated. This batter should be thick but pourable. Let it rest for 10 minutes at room temperature while you prepare the apples and streusel. This resting period allows the flour to fully hydrate and relax, preventing a dense cake.
Create the Spiced Apple Filling and Streusel Topping
While the batter rests, peel, core, and slice the 4 medium Granny Smith apples into ¼-inch thick slices. Toss them with 1 teaspoon ground cinnamon and set aside. For the streusel, pulse the 1 cup old-fashioned rolled oats in a food processor until they resemble coarse flour. Transfer to a bowl and mix with the remaining 1 teaspoon ground cinnamon, 0.5 teaspoon ground nutmeg, 0.5 teaspoon ground ginger, 0.5 cup light brown sugar, and the 1 cup cold cubed unsalted butter.
Use your fingers to work the butter into the oat mixture until it resembles coarse crumbs with pea-sized butter pieces. This texture is key—it should hold together when pressed but still allow for a crispy, caramelized topping. If the mixture seems too dry, add 1 tablespoon milk to help it bind.
Assemble and Bake the Bundt Cake
Preheat your oven to 350°F and grease a 10-cup Bundt pan thoroughly with butter and flour, tapping out any excess. Arrange half of the apple slices in a circular pattern in the bottom of the pan, leaving a ½-inch border. Pour half of the cake batter over the apples, then add the remaining apple slices. Top with the remaining batter, gently pressing down to eliminate air pockets.
Sprinkle the streusel mixture evenly over the top, pressing down lightly to ensure good contact with the cake. Bake for 50-55 minutes, or until a toothpick inserted into the center comes out clean and the top is golden brown. The cake is done when the edges pull away slightly from the pan and the internal temperature reaches 205°F.
Cool and Glaze for Perfect Presentation
Remove the cake from the oven and let it cool in the pan for 15 minutes. Then invert onto a wire rack to cool completely. This gradual cooling prevents cracking and allows the cake to set properly. While the cake cools, prepare the vanilla glaze by whisking together the 1 cup vanilla glaze powder and 0.25 cup milk until smooth. The glaze should be thick enough to coat the back of a spoon but still drizzleable.
Once the cake is completely cool, drizzle the glaze evenly over the top and sides. For an elegant finish, use a fork to create decorative drips down the sides. The glaze will set as it cools, creating a beautiful, professional-looking finish. Serve slices at room temperature for the best texture and flavor.
Pro Tips For Making America'S Test Kitchen Apple Bundt Cake
- Cream Butter Slowly: The recipe calls for softened butter, but don’t just eyeball it—press it between your fingers until it leaves a slight imprint but still holds shape. I learned this the hard way when my cake turned dense because the butter was too warm and melted into the sugar.
- Sift the Dry Mix: The ATK recipe relies on baking powder for lift, so don’t skip sifting the flour, sugar, and baking powder together. A few extra seconds with a fine-mesh sifter guarantees no lumps and a lighter crumb—trust me, your cake will rise better.
- Don’t Overmix the Batter: Once you fold in the apples, stop mixing the moment everything is just combined. Overworking the batter introduces too much gluten, and your cake will turn tough instead of tender. I used to ignore this and wondered why my bundt cake had a bread-like texture.
- Grease and Flour the Bundt Pan: The recipe says to grease it, but I’ve found that adding a light dusting of flour afterward prevents sticking—especially in the tight corners. Just tap out the excess so it doesn’t make the cake dry. (Yes, it’s extra work, but your cake will come out cleanly.)
Troubleshooting great america's test kitchen apple bundt cake
Dense Cake Texture
If your bundt cake turns out dense instead of tender, overmixing the batter is likely the culprit. Once you've incorporated the dry ingredients, stop mixing immediately—just until combined. I've found that using a stand mixer on low speed helps prevent overdevelopment.
Also, ensure your buttermilk is cold (not room temperature) and your flour is sifted before measuring. If the batter seems too thick, add 1 tablespoon milk at a time until it reaches a smooth, pourable consistency. 🥄
Streusel Too Dry
The streusel should hold together when pressed but still crumble easily. If it's too dry, the butter isn't properly distributed. Work the 1 cup cold cubed butter into the oat mixture using your fingers until you see pea-sized butter pieces throughout.
If needed, add 1 tablespoon milk to help bind the ingredients. For extra moisture, try substituting ½ cup of the oats with finely chopped dried apricots—they add natural sweetness and moisture. 🧈
Apples Too Mushy
Overly soft apples ruin the texture of the cake. To prevent this, slice the Granny Smith apples no thicker than ¼ inch and toss them with 1 teaspoon cinnamon immediately after slicing.
If your apples are particularly soft (like Honeycrisp), sprinkle them with ½ teaspoon lemon juice before baking to help firm them up. Bake the cake for no longer than 55 minutes—overbaking causes the apples to break down completely. 🍎
Cake Sticking to Pan
A poorly greased bundt pan is the most common cause of a stuck cake. Use 1 tablespoon melted butter to coat the pan thoroughly, then dust with 2 tablespoons all-purpose flour, tapping out any excess.
For extra insurance, I like to use Bundt pan release spray (like Pam) in addition to butter and flour. If the cake still sticks, run a thin metal spatula around the edges before inverting onto a wire rack. Never force it—patience prevents cracks! 🧂
Streusel Not Crispy
Underbaked streusel loses its crunch. To fix this, bake the cake for 5-10 minutes longer until the streusel is deep golden brown and crisp to the touch. For a more pronounced texture, try adding ½ teaspoon cornstarch to the streusel mixture—it enhances browning.
If your oven runs hot, reduce the temperature to 325°F for the last 10 minutes of baking to ensure even caramelization. 🔥
Cracked Cake
Sudden temperature changes or uneven cooling cause cracks. After baking, let the cake cool in the pan for 15 minutes before inverting onto a wire rack. Avoid placing it on a cold surface—use a cooling rack instead.
If cracks appear, they're usually superficial. For a smoother finish, brush the glaze over the cracks before it sets completely. 💫

Frequently asked questions
Can I make this bundt cake without a bundt pan?
Yes, but the shape will differ! Use a 9-inch round or tube pan instead. The cake will still taste delicious, though the layers won't have the signature bundt cake design. Grease the pan thoroughly to prevent sticking, and bake for 40-45 minutes at 350°F instead. The streusel will still caramelize beautifully.
How do I store leftovers to keep the streusel crispy?
Store the cake at room temperature in an airtight container for up to 3 days. For longer storage, wrap the cake tightly in plastic wrap and place it in the freezer for up to 3 months. To refresh the streusel, reheat slices in the oven at 300°F for 5 minutes before serving.
Can I substitute the apples with another fruit?
Try peaches, pears, or berries for a different flavor twist. For peaches or pears, use 2 cups sliced fruit and reduce the cinnamon to ½ teaspoon to avoid overpowering the flavor. Berries work well if chopped into ¼-inch pieces—add them to the batter instead of layering.
Why does the recipe call for both butter and oil?
The combination creates the perfect texture: butter adds rich flavor and tenderness, while oil keeps the cake moist without making it greasy. The oil also helps the cake rise more evenly. For a dairy-free version, replace the butter with vegan butter or extra oil. The cake will still turn out light and flavorful!
How do I know when the cake is fully baked?
The cake is done when a toothpick inserted into the center comes out clean and the internal temperature reaches 205°F. The edges should also pull away slightly from the pan, and the streusel should be golden brown. Overbaking can make the apples mushy, so don't exceed 55 minutes.
