Ingredients for applesauce sheet cake
Twelve ingredients crafting a moist, spiced apple cake with buttery crunch topping—no frosting needed.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for streusel |
| Light Brown Sugar 🍚 | 1 ½ cups | Packed firmly for streusel |
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted, spooned lightly |
| Granulated Sugar 🍚 | 1 ½ cups | For cake layer |
| Unsweetened Applesauce 🍎 | 1 cup | Unseasoned, unsweetened |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Vanilla Extract 🌿 | 2 tsp | Pure, high-quality |
| Ground Cinnamon 🌶️ | 2 tsp | For cake layer |
| Ground Nutmeg 🌿 | ½ tsp | Freshly grated preferred |
| Ground Allspice 🌶️ | ½ tsp | For depth of flavor |
| Baking Powder 🧂 | 2 tsp | Aluminum-free preferred |
| Baking Soda 🧂 | ½ tsp | For leavening |
| Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Old-Fashioned Oats 🌾 | 1 cup | Blended into flour for streusel |
| Chopped Walnuts 🥜 | ½ cup | Toasted for streusel |
The applesauce is the game-changer here—opt for unsweetened, unseasoned from the refrigerated section at Whole Foods or Trader Joe's for the best texture. Mott's or Libby's work in a pinch, but avoid those with added spices or sugar. For the streusel, Land O'Lakes unsalted butter (or European-style) creates the ideal caramelized crust. If you prefer a nuttier flavor, pecans can replace walnuts, though they soften faster during baking. The brown sugar should be light, not dark—it balances sweetness without overpowering the warm spices.
No applesauce? Pumpkin puree at a 1:1 ratio works surprisingly well, though the flavor profile shifts slightly. Running short on walnuts? Chopped pecans or toasted sunflower seeds add texture without altering the cake's structure. The vanilla extract must be pure—Nielsen-Massey or McCormick are reliable brands. For the streusel, if you're feeling adventurous, add 1 tsp of cinnamon to the topping mix for extra warmth. The oats should be old-fashioned, not quick oats—they hold their shape better. Pre-blending them into flour prevents clumping in the streusel.
This cake stays moist for up to 5 days when stored in an airtight container at room temperature, though the streusel loses crispness after 2 days. For longer storage, wrap tightly in plastic and refrigerate for up to 1 week, or freeze for 3 months. To reheat, cover with foil and warm at 300°F for 10 minutes. The streusel topping is best enjoyed fresh, so assemble the cake just before serving. Double the recipe for large gatherings—this sheet cake scales perfectly for a 9x13-inch pan or two 9-inch rounds.

Step-by-step instructions for applesauce sheet cake with buttery streusel
A tender, spiced cake layer meets a crumbly, caramelized streusel—this method delivers perfect texture every time.
Prepare the Cake Batter with Applesauce Moisture
Preheat your oven to 350°F and grease a 9x13-inch baking pan, then line it with parchment paper for easy removal. In a large mixing bowl, combine the 1.5 cups granulated sugar, 2 whole large eggs, and 2 teaspoons vanilla extract, whisking until fully incorporated and the mixture is pale and slightly thickened.
Gradually add the 1 cup unsweetened applesauce while mixing continuously. The applesauce replaces some fat and eggs, creating a naturally moist crumb without adding extra liquid. In a separate bowl, sift together the 2.5 cups all-purpose flour, 2 teaspoons ground cinnamon, 0.5 teaspoon ground nutmeg, 0.5 teaspoon ground allspice, 2 teaspoons baking powder, 0.5 teaspoon baking soda, and 0.5 teaspoon salt. Gently fold the dry ingredients into the wet mixture using a spatula, being careful not to overmix—just until combined. The batter should be smooth with a few small lumps remaining.
Make the Streusel Topping with Cold Butter
While the cake batter rests, prepare the streusel topping in a medium bowl. Cut the 1 cup cold unsalted butter into small cubes and place them in the bowl. Add the 1.5 cups packed light brown sugar, 1 cup old-fashioned oats (blended into a fine powder if needed), and 0.5 cup chopped walnuts. Using your fingers or a pastry cutter, work the butter into the dry ingredients until the mixture resembles coarse crumbs with some pea-sized butter pieces remaining—this ensures a crumbly, flavorful topping rather than a dense layer.
In a small bowl, whisk together 1 teaspoon ground cinnamon, 0.25 teaspoon ground nutmeg, and 0.25 teaspoon ground allspice. Sprinkle this spice mixture evenly over the streusel and toss gently to distribute. The streusel should look speckled with spices and nutty bits, ready to caramelize beautifully on top of the cake.
Assemble and Bake to Golden Perfection
Pour the cake batter evenly into the prepared baking pan and spread it into the corners with a spatula, creating an even layer. Sprinkle the streusel topping evenly over the batter, pressing down lightly with your fingers to ensure good contact—this helps the streusel brown and crisp rather than stay pale. Bake for 40-45 minutes until the edges are golden brown and a toothpick inserted into the center comes out clean with a few moist crumbs (not wet batter).
I always check for doneness at the 35-minute mark15 minutes before transferring to a wire rack to cool completely. The contrast between the soft, spiced cake and the buttery, crunchy streusel is what makes this recipe truly special.
Serve with Warm, Crumbly Topping
Once fully cooled, slice the cake into 12 equal squares (about 2x2-inch pieces) for serving. The cake should be moist but not gummy, with a tender crumb that holds its shape. The streusel topping should be crisp around the edges and slightly caramelized, offering a delightful textural contrast with each bite. I like to serve this cake warm or at room temperature, paired with a dollop of whipped cream or a scoop of vanilla ice cream for an extra touch of indulgence.
For best results, store any leftovers in an airtight container at room temperature for up to 3 days. The cake will keep its moisture, though the streusel may soften slightly—reheat briefly in the oven to restore its crunch. This recipe delivers on its promise of a moist, flavorful cake with a buttery, spiced topping that’s as satisfying as it is delicious.
Pro Tips For Making Applesauce Sheet Cake
- MEASURE APPLESAUCE PRECISELY: I learned this the hard way—using "about a cup" of applesauce leads to a cake that’s either too dense or too wet. Weigh it instead: 1 cup of unsweetened applesauce is roughly 240 grams. Too much, and your cake will sink like a lead balloon; too little, and it’ll taste like a dry sponge.
- CREAM BUTTER AND SUGAR UNTIL PALE: This isn’t the prettiest method, but it’s the tastiest. Beat the unsalted butter and sugars until the mixture is light, fluffy, and actually turns a pale yellow (about 3-4 minutes). Skimp here, and your cake will taste flat—like someone forgot to aerate the batter.
- DON’T OVERMIX THE BATTER: I was skeptical until I tried it: stop mixing as soon as the flour is just incorporated. Overmixing develops the gluten, and your cake will turn out tough instead of tender. The second the flour disappears, call it done—even if it looks lumpy.
- LET THE BATTER REST: This is the thing that matters most if you’re baking it the same day. After mixing, let the batter sit for 10-15 minutes while you preheat the oven. The flour absorbs the applesauce better, and the cake rises more evenly—no more cracked tops or dense centers. (Yes, even if you’re impatient like me.)
Pro cooking tips for applesauce sheet cake
Applesauce Substitution
The 1 cup unsweetened applesauce replaces both oil and some eggs, creating a moist cake without added grease. For best results, use unsweetened, unseasoned applesauce—brands like Mott's or Whole Foods 365 work perfectly. If you don’t have applesauce, substitute ½ cup pumpkin puree (for moisture) or ½ cup Greek yogurt (for tang). Avoid sweetened varieties—the extra sugar can make the cake too sweet. 🍎
Butter Temperature Matters
For the streusel topping, cold cubed butter is non-negotiable—it creates those perfect golden-brown, crumbly bits. Cut 1 cup unsalted butter into small cubes and keep them chilled until ready to mix. If your butter melts too quickly, chill the bowl for 10 minutes before combining. European-style butter (like Plugrá) has a higher fat content, which enhances caramelization. 🧈
Prevent Overmixing
When folding the dry ingredients into the wet batter, stop mixing as soon as combined—overmixing develops gluten, leading to a tough cake. Use a spatula and mix just until the flour disappears. The batter should look slightly lumpy, not smooth. I often count 15-20 gentle folds to avoid overworking. This ensures a tender, moist crumb that melts in your mouth. 💪
Streusel Distribution
Evenly distribute the streusel topping by pressing lightly with your fingers after sprinkling. This ensures the streusel makes contact with the cake, caramelizing beautifully instead of staying pale. For extra crunch, bake the streusel alone for 2-3 minutes before adding it to the cake—this pre-baking step creates a deeper golden color. 🌟
Oven Thermometer Check
Ovens run hot or cold, so always verify your oven’s accuracy with an oven thermometer. If your oven reads 350°F but actually runs at 325°F, your cake may take longer to bake. Adjust the temperature accordingly—this cake benefits from a true 350°F environment for even baking. I keep a Thermoworks Oven Thermometer in my kitchen for this exact reason. ⚡
Cool Before Slicing
Let the cake cool in the pan for 15 minutes before transferring to a wire rack. This prevents the streusel from cracking or falling apart when sliced. Wait until the cake is completely cool (about 1 hour total) before serving. The streusel will firm up as it cools, creating the perfect crunchy contrast. Patience here makes all the difference! 🕒

Frequently asked questions
Can I make this applesauce cake without a streusel topping?
The streusel adds that perfect crunchy contrast, but you can absolutely skip it! Simply bake the cake layer as directed and top with a dusting of cinnamon sugar or a light dusting of powdered sugar. The cake will still be moist and flavorful—just without the buttery crunch.
How do I adjust this recipe for a 9-inch round pan instead of a sheet pan?
For a 9-inch round pan, reduce the batter to 2/3 of the original recipe (about 1.67 cups flour and 1 cup applesauce). Bake at 350°F for 30-35 minutes until golden. The streusel amount stays the same, but spread it evenly over the smaller surface. Double the recipe for two 9-inch layers if you want a taller cake.
Why did my cake turn out dense instead of moist?
Overmixing the batter is the most common culprit—stop folding the dry ingredients in as soon as they disappear. Also, ensure your applesauce is unsweetened and unseasoned, and don't substitute with sweetened varieties. Finally, check your oven temperature with a thermometer—if it's running hot, reduce to 325°F for even baking.
Can I add apples to this cake for extra flavor?
While this recipe relies on applesauce for moisture, you can absolutely add ½ cup finely diced apples (peeled and tossed with 1 tsp lemon juice) to the batter. Fold them in gently after mixing the wet ingredients. For best results, use tart apples like Granny Smith—they hold their shape better during baking.
How long can I keep this cake at room temperature?
The cake stays moist and delicious for 3-4 days when stored in an airtight container at room temperature. The streusel topping may soften slightly after 2 days, but reheating at 300°F for 10 minutes restores its crunch. For longer storage, refrigerate for up to 1 week or freeze for 3 months.
