Ingredients for america's test kitchen apple bundt cake

Twelve ingredients transform into a showstopping bundt cake with caramelized apple filling that stays moist for days.

The apples make or break this cake—Granny Smith delivers that perfect tartness, but Honeycrisp or Fuji work beautifully too. Local farmers markets often have the freshest, crispest varieties, but any medium-sized apple will do. Peel and dice them into even 1/2-inch pieces (no smaller, or they'll turn to mush). For the filling, corn syrup is key—it caramelizes beautifully and keeps the filling moist. If you're feeling fancy, grab organic apples from Whole Foods, but regular supermarket apples work perfectly fine. The cinnamon and nutmeg? Penzeys Spices has the best quality, but the grocery store stuff will do in a pinch.

No applesauce? Unsweetened applesauce from the store works, but if you're feeling ambitious, make your own by cooking down peeled apples with a splash of water. Short on corn syrup? Maple syrup at half the amount gets you close. The vanilla extract is non-negotiable—pure vanilla bean extract makes all the difference, but imitation will work if that's what you've got. For the flour, King Arthur or Gold Medal brands are ideal, but any all-purpose will suffice. The butter needs to be room temperature—microwave for 40 seconds if it's straight from the fridge. And trust me, the baking powder must be fresh—if it's more than six months old, toss it and buy a new can.

This cake tastes even better the next day—cover tightly with plastic wrap to keep it moist. Store at room temperature for 3 days or in the fridge for 1 week. For longer storage, wrap tightly in foil and freeze for up to 3 months. The filling stays perfectly set, so you can slice and serve straight from the freezer. I always make a double batch—one for the table and one to freeze for future cravings. The bundt pan shape makes it perfect for individual servings, so you can easily portion it out for parties or potlucks.

Step-by-step instructions for america's Test Kitchen apple bundt cake

Here's how to bake a perfectly moist apple bundt cake with a spiced filling that stays delicious for days.

Peel and dice the 4 medium Granny Smith apples into ½-inch pieces—smaller pieces caramelize faster but keep them uniform for even baking. In a medium bowl, combine the apple pieces with 0.25 cup light corn syrup, 1 tbsp freshly squeezed lemon juice, 1.5 tsp ground cinnamon, and 0.5 tsp ground nutmeg. Toss gently to coat evenly. Let this mixture sit for 10 minutes while you prepare the batter—this allows the spices to infuse and the apples to soften slightly.

Here's the thing—Granny Smith apples are tart and hold their shape well, which prevents a mushy filling. The corn syrup and lemon juice act as natural tenderizers, while the spices add warmth that balances the tartness. Don't skip the resting time; it makes all the difference in texture.

In a stand mixer fitted with the paddle attachment, beat the 1 cup unsalted butter (room temperature) with 1.5 cups granulated sugar and 0.5 cup packed light brown sugar on medium speed for 3-4 minutes. You're aiming for a light, fluffy texture—the mixture should nearly double in volume and become pale. Scrape down the sides of the bowl with a rubber spatula every 30 seconds to ensure even mixing.

This creaming process incorporates air into the batter, which creates that signature tender crumb in bundt cakes. I always use room-temperature butter here—it blends more smoothly and prevents lumps. You'll know it's ready when the mixture looks like whipped cream and leaves clean streaks when you drag the spatula through it.

Add the 2 whole large eggs (room temperature) to the butter-sugar mixture, one at a time, mixing on low speed for 30 seconds after each addition until fully incorporated. Then add the 0.5 cup unsweetened applesauce and 1 tbsp pure vanilla extract, mixing on low speed for another 30 seconds until smooth. The applesauce replaces some of the butter, keeping the cake moist without adding extra fat.

This is where the magic happens—the applesauce adds natural moisture and helps create that signature tender crumb. I like to add the vanilla last because its delicate flavor can get overwhelmed by the other ingredients. The mixture should be thick but still pourable—if it looks too stiff, don't worry, the dry ingredients will lighten it up.

In a separate bowl, whisk together the 2.5 cups sifted all-purpose flour, 1.5 tsp baking powder, and 0.5 tsp fine sea salt. With the mixer on low speed, gradually add the dry ingredients to the wet mixture, mixing just until combined—you should still see a few flour streaks. This prevents overmixing, which can make the cake tough. Then fold in the prepared apple mixture using a silicone spatula, being careful not to overmix.

Here's the crucial part: don't overmix. You want to maintain as much air as possible in the batter for that light, tender texture. The apple filling will sink slightly as it bakes, but the cake's structure will hold it beautifully. The batter should be thick but still spreadable—if it's too stiff, you can gently fold in 1-2 tablespoons of milk (though the recipe doesn't call for it, this is my secret weapon for tricky batters).

Preheat your oven to 350°F and generously grease a 10-12 cup bundt pan with butter, then dust it with flour, tapping out any excess. Pour the batter into the prepared pan and smooth the top with a spatula. Bake for 50-60 minutes, until a toothpick inserted into the center comes out clean and the cake is deep golden brown at the edges. The cake is done when it springs back slightly when pressed in the center.

Don't open the oven door during the first 30 minutes of baking—this prevents the cake from sinking in the middle. The bundt pan creates beautiful ridges, but the real magic is in the timing. If the top browns too quickly, tent the cake with foil to prevent over-browning. Let it cool in the pan for 15 minutes, then transfer to a wire rack to cool completely before unmolding.

Dietary considerations for this recipe

Gluten-Free Adaptation

For a gluten-free version, replace the 2.5 cups all-purpose flour with 2 cups gluten-free 1:1 baking flour (like Bob’s Red Mill or King Arthur) plus 0.5 cup cornstarch. Add 1 extra tablespoon of applesauce to compensate for reduced moisture retention. Sift the gluten-free flour thoroughly to avoid lumps, and let the batter rest for 10 minutes before baking to improve texture. 💪

Dairy-Free Options

Swap the 1 cup unsalted butter for 1 cup dairy-free butter (Miyoko’s or Earth Balance) or 1 cup coconut oil (melted and cooled). Use 2 tablespoons of dairy-free milk (almond or oat) if the batter seems too thick. The applesauce and corn syrup already provide moisture, so no additional adjustments are needed. The texture will be just as tender!

Lower-Sugar Version

Reduce the 1.5 cups granulated sugar to 1 cup and the 0.5 cup brown sugar to 0.25 cup. Add 2 tablespoons of monk fruit sweetener (like Lakanto) or 1 tablespoon of erythritol to maintain sweetness without spiking blood sugar. The applesauce helps balance the reduced sugar, keeping the cake moist. Taste the batter before baking—you may need 1 extra teaspoon of vanilla extract for depth. 💛

Nut-Free Considerations

This recipe is naturally nut-free, but always check labels on ingredients like vanilla extract (some brands use almond extract) and applesauce (some contain added nut oils). If you’re serving guests with nut allergies, double-check all spices (like cinnamon or nutmeg) for cross-contamination warnings. Store-bought baking powder is typically safe, but verify if using a homemade blend.

Vegan Modifications

Replace the 2 eggs with 2 flax eggs (2 tablespoons ground flaxseed + 6 tablespoons water, mixed and rested for 5 minutes). Use dairy-free butter (as above) and dairy-free vanilla extract. The applesauce and corn syrup keep the cake moist without needing egg substitutes for structure. Bake for 55-65 minutes, as vegan cakes often take slightly longer to set. 🌱

Allergen-Friendly Tips

For egg-free bakers, the flax egg substitution works well, but test the batter’s thickness—add 1 tablespoon of water if needed. If avoiding corn syrup, use 0.25 cup maple syrup (reduce other liquids by 1 tablespoon). Always label your cake clearly if serving multiple allergens, and consider a separate baking surface if cross-contamination is a concern. Safety first!
