Desserts
America's Test Kitchen's apple bundt cake delivers moist, tender layers with a signature streusel crown that's crisp yet crumbly—no dry crumbs here. 💛 The secret lies in precise moisture balance: apples stay juicy while the cake maintains its structure, and the streusel topping stays perfectly textured without turning into a paste. This isn't your grandmother's bundt cake; it's a refined dessert that bakes up with a golden dome and a tender crumb that defies the 45-minute bake time.
What sets this recipe apart is the foolproof method for achieving even baking in a bundt pan, where temperature control and proper greasing prevent sticking. The cake itself is enriched with buttermilk for moisture, while the streusel—made with oats, brown sugar, and cinnamon—adds a satisfying crunch that contrasts beautifully with the soft cake. Every bite delivers that perfect harmony of spiced apple flavor without being overly sweet, thanks to carefully calibrated measurements and baking times tested to perfection.
By the time it emerges from the oven, you'll have a cake that's golden brown at the edges with a crown of streusel that holds its shape, not crumbling into the cake. The aroma alone—warm apples, cinnamon, and vanilla—will have everyone gathering around the kitchen. This is the kind of bundt cake that earns second helpings and compliments, proving that even home bakers can achieve restaurant-quality results with the right technique.
The best part? It's designed for reproducibility—no guessing about doneness, no risk of a sunken center, and no need for fancy equipment beyond a standard bundt pan. Whether you're serving it warm with vanilla ice cream or letting it cool slightly for cleaner slices, this recipe delivers a dessert that's as impressive as it is delicious. Let's get baking—your taste buds will thank you.
Ingredients for america's test kitchen apple bundt cake
Twelve simple ingredients for a bundt cake that's moist, tender, and crowned with perfect streusel.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for light texture |
| Granulated Sugar 🍚 | 1 ½ cups | White sugar preferred |
| Light Brown Sugar 🍚 | ½ cup | Packed firmly |
| Unsalted Butter 🧈 | 1 cup | Room temperature, not melted |
| Buttermilk 🥛 | 1 cup | Room temperature |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Vanilla Extract 💧 | 1 tbsp | Pure vanilla preferred |
| Ground Cinnamon 🌿 | 2 tsp | Freshly ground preferred |
| Baking Powder 🧂 | 2 tsp | Aluminum-free preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Apples 🍎 | 2 ½ cups | Peeled, finely diced (Honeycrisp or Fuji) |
| Old-Fashioned Rolled Oats 🌾 | 1 cup | Not instant oats |
| Light Brown Sugar (Streusel) 🍚 | ½ cup | Packed firmly |
| Ground Cinnamon (Streusel) 🌿 | 1 tbsp | Same as cake |
| Unsalted Butter (Streusel) 🧈 | ½ cup | Cold, cubed |
The apples make or break this cake. Honeycrisp or Fuji are ideal—they stay juicy without turning mushy. Trader Joe's and Whole Foods usually carry them pre-peeled, but if you're peeling yourself, keep the knife sharp to avoid bruising. For the butter, Plugrá or Land O'Lakes work great, but any good-quality unsalted will do. The key is getting it to room temperature—stick it in the fridge for 10 minutes if it's too soft. The buttermilk? If yours is curdled, strain it through a fine-mesh sieve first.
No buttermilk? Substitute 1 cup milk + 1 tbsp vinegar or lemon juice, let sit 5 minutes. Running short on apples? Substitute diced pear or tart cherry, but reduce by 1/4 cup to avoid excess moisture. The oats in the streusel must be old-fashioned—instant oats will turn gummy. For a deeper cinnamon flavor, toast the oats and sugar together in a dry pan for 2 minutes before mixing. The baking powder is non-negotiable here—aluminum-free ensures no metallic aftertaste. And if you're worried about the cake sticking, use both butter and flour to grease your bundt pan.
Store the cake in an airtight container at room temperature for up to 3 days, or freeze for 2 months. The streusel stays crisp for about 2 days before it softens, so make it fresh if you can. I like to slice it warm with vanilla ice cream—Breyers or Ben & Jerry's both work perfectly. For extra flavor, brush the warm cake with a simple syrup made from equal parts sugar and water. This cake also reheats beautifully—30 seconds in the microwave brings back that fresh-from-the-oven magic.

Step-by-step instructions for america's test kitchen apple bundt cake
Here's how we achieve that signature moist crumb and perfect streusel crown every time.
👨🍳 Step 1: Mix the Cake Batter for Maximum Moisture
In a large mixing bowl, whisk together the 2.5 cups All-Purpose Flour, 2 tsp Baking Powder, 2 tsp Ground Cinnamon, and 0.5 tsp Salt. Sifting the flour first prevents lumps and ensures an even texture. In a separate bowl, beat the 1 cup Unsalted Butter (room temperature) with the 1.5 cups Granulated Sugar and 0.5 cup Light Brown Sugar on medium speed for 3-4 minutes until light and fluffy.
Add the 2 whole Large Eggs one at a time, mixing well after each addition. Stir in the 1 cup Buttermilk and 1 tbsp Vanilla Extract until just combined. Here's the thing—we're not overmixing. The moment the dry ingredients disappear, fold in the 2.5 cups Apples gently with a spatula. Overmixing develops gluten, which makes the cake tough instead of tender. The batter should be thick but pourable.
🥘 Step 2: Prepare the Streusel Topping
In a medium bowl, combine the 1 cup Old-Fashioned Rolled Oats, 0.5 cup Light Brown Sugar (Streusel), 1 tbsp Ground Cinnamon (Streusel), and 0.5 cup Unsalted Butter (Streusel) (cold, cubed). Use your fingers or a pastry cutter to work the butter into the oat mixture until it resembles coarse crumbs with some pea-sized butter pieces remaining. This texture ensures a perfect balance of crispy and tender in the streusel.
Don't pulse this in a food processor—you want some variation in texture. The streusel should hold its shape when sprinkled but still have pockets of butter to melt and create that signature caramelized crown. If it looks too wet, add 1-2 tablespoons more oats until it reaches the right consistency.
🔥 Step 3: Bake the Bundt Cake to Golden Perfection
Preheat your oven to 350°F. Generously grease a 10-12 cup Bundt pan with butter and dust with flour, tapping out any excess. Pour the cake batter into the prepared pan and sprinkle the streusel topping evenly over the top, pressing down lightly to help it adhere. Bake for 50-60 minutes until a toothpick inserted in the center comes out clean and the top is golden brown.
Here's where precision matters: the cake is done when the internal temperature reaches 205-210°F. If the streusel isn't browned enough after 50 minutes, tent the cake with foil and continue baking. The residual heat will finish browning the streusel without overcooking the cake underneath. Don't open the oven door during baking—this causes the cake to sink.
⏰ Step 4: Cool and Serve for Maximum Moisture Retention
Remove the cake from the oven and let it cool in the pan for 15 minutes. This resting period allows the cake to set slightly before removing it. Run a knife around the edges to loosen, then invert the cake onto a wire rack. Let it cool completely before serving—this prevents the cake from becoming gummy as it cools.
I know it's tempting to slice into that warm cake, but patience pays off here. The cake will be moist and tender when fully cooled, with that perfect streusel crown that cracks when you cut into it. Serve slices with a dollop of whipped cream or a scoop of vanilla ice cream for the ultimate experience.
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 your thumb into the butter and if it springs back after 10 seconds, you’re good. I learned this the hard way when my cake turned out dense because the butter was too warm and melted into the flour too fast.
- Measure Dry Ingredients Right: Spoon the flour, sugar, and brown sugar directly into the bowl without scooping with the measuring cup—packing it down changes the texture. I used to rush this, and my cake would either sink or taste off-balance.
- Don’t Overmix the Batter: Mix the wet and dry ingredients just until combined—no more than 20 strokes. Overmixing develops gluten, and that’s why my first few attempts came out tough instead of tender. The recipe’s lightness depends on stopping early.
- Test for Doneness Early: The cake’s done when the edges pull away from the pan and a toothpick comes out with a few moist crumbs, not wet batter. I’ve pulled cakes too soon, and they’d collapse later—wait until the center’s set but still slightly springy.
Perfect pairings for this america's test kitchen apple bundt cake
Creamy Ice Cream
Vanilla bean ice cream is the classic pairing—its cool creaminess contrasts beautifully with the warm spiced cake. I reach for Breyers Natural Vanilla Bean or Ben & Jerry's Phish Food (the caramel swirl adds a fun twist). For a lighter option, try Häagen-Dazs Dutch Chocolate, which balances the apple's tartness. Always serve ice cream slightly softened so it melts gently into the cake's moist crumb. 🍦
Whipped Cream
A dollop of lightly sweetened whipped cream elevates every slice. I make mine with heavy whipping cream (chilled overnight) and 2 tbsp powdered sugar, whipped until soft peaks form. For extra flavor, fold in ½ tsp vanilla extract or a pinch of cinnamon. A quick tip: Add 1 tsp lemon juice to stabilize the whipped cream for longer-lasting peaks. The acidity also brightens the apple's flavor.
Caramel Sauce
Warm caramel sauce turns this dessert into a showstopper. My go-to recipe uses 1 cup granulated sugar, 6 tbsp unsalted butter, and ½ cup heavy cream. Simmer the sugar until amber, then whisk in butter and cream. Drizzle over slices or serve on the side for dipping. For a quicker version, use store-bought salted caramel sauce (like Trader Joe's) and warm it gently. The salt enhances the apple's natural sweetness.
Spiced Compote
An apple compote adds another layer of apple flavor. Simmer 2 cups diced apples (same variety as your cake), ¼ cup brown sugar, 1 tsp cinnamon, and 2 tbsp water for 10 minutes until thickened. Strain for a smooth sauce or leave it chunky. Serve warm over cake slices or alongside for dipping. This works especially well if you're serving the cake slightly cooled—it reheats beautifully.
Coffee Pairing
For a sophisticated twist, serve with a dark roast coffee like Starbucks Sumatra or local roaster's cold brew. The bitterness cuts through the cake's richness while complementing the cinnamon. I like to add a splash of heavy cream to my coffee to mirror the whipped cream topping. For an iced option, try cold brew concentrate with a splash of milk—it's refreshing and balances the cake's warmth.
Cheese Pairing
Don't overlook cheese! A sharp aged cheddar (like Cabot Clothbound Cheddar) or creamy brie** (like President Brie) adds a savory contrast. Serve small cubes alongside the cake for guests to sample. The cheese's saltiness enhances the apple's sweetness, creating a perfect balance. For a fun presentation, arrange cheese cubes on a platter with crackers and the cake slices. 🧀

Frequently asked questions
Why does this bundt cake recipe use buttermilk?
The buttermilk adds moisture and tenderness to the cake while creating a subtle tang that balances the sweetness. It also helps activate the baking powder for a lighter crumb. Never substitute with regular milk—the acidity is key for that perfect texture.
Can I make this cake without a bundt pan?
Yes! Use a 9-inch round or tube pan instead. The cake will still be delicious, though the shape will differ. For best results, grease the pan well and reduce baking time by 5-10 minutes since the sides won't be as thick. The streusel will still work beautifully on top.
What's the best way to store leftover bundt cake?
Keep it in an airtight container at room temperature for up to 3 days. For longer storage, freeze slices wrapped in plastic for 2 months. The cake reheats wonderfully—30 seconds in the microwave restores that fresh-baked aroma. The streusel stays crisp for about 2 days before softening.
My cake came out dry—what went wrong?
Overbaking is the most common cause. The cake is done when the internal temperature reaches 205-210°F—don't rely solely on time. Also check your oven temperature with an oven thermometer (many run hot). Another fix: brush warm slices with simple syrup (equal parts sugar and water) to restore moisture.
Can I substitute pears or cherries for the apples?
Yes, but adjust quantities carefully. Use 1 cup less diced pear (they're juicier) or 1 cup tart cherries (pitted) instead of apples. For pears, Bosc or Anjou varieties work best. Cherries should be tart (like Montmorency) to match the apple's flavor profile. The baking time may vary slightly.
