Step-by-Step Instructions
Step 1: Prepare the oven and pan
Position a rack in the center of the oven and preheat to 350°F (175°C), using a conventional oven setting. Grease a 9 × 13-inch metal baking pan with 1 teaspoon softened butter. Line the bottom with parchment paper for easier serving.
Set out the eggs and applesauce before you begin so they are not refrigerator-cold. The butter should be soft enough to hold a shallow fingerprint but should not look melted or greasy.
Step 2: Whisk the dry ingredients
In a medium bowl, whisk together the flour, baking soda, baking powder, salt, cinnamon, nutmeg, and cloves for about 30 seconds. Break up any small clumps so the spices and leavening are evenly distributed throughout the cake.
Step 3: Cream the butter and brown sugar
In a large mixing bowl, beat the softened butter and brown sugar with an electric mixer on medium speed for 3 minutes, scraping down the bowl halfway through. The mixture should look lighter and fluffier, although it will still have a slightly sandy texture from the brown sugar.
Add the eggs one at a time, beating for 30 seconds after each addition. Beat in the vanilla, then scrape the bottom and sides of the bowl.
Step 4: Mix in the applesauce and flour
With the mixer on low speed, add one-third of the dry ingredients, followed by half of the applesauce. Repeat with another third of the dry ingredients and the remaining applesauce, then finish with the last third of the dry ingredients.
Mix only until the flour disappears. Use a flexible spatula to scrape the bowl and fold the batter a few times, checking for dry pockets at the bottom. The batter will be thick, soft, and spreadable. Transfer it to the prepared pan and smooth the top into an even layer.
Step 5: Bake and cool the cake
Bake for approximately 40 minutes, beginning to check at 35 minutes. The top should look set, the center should spring back gently when touched, and a toothpick inserted into the middle should come out clean or with a few moist crumbs—not wet batter. If needed, continue baking in 3-minute increments until done.
Place the pan on a wire rack and let the cake cool completely in the pan, about 90 minutes. Do not begin the frosting until the cake is cool; the frosting thickens quickly once the powdered sugar is added.
Step 6: Cook the caramel frosting base
Combine the butter, brown sugar, and heavy cream in a medium, heavy-bottomed saucepan. Cook over medium heat, stirring constantly, until the butter melts and the mixture reaches a gentle boil across the surface, about 4 minutes.
Once it is gently boiling, cook for exactly 1 minute, continuing to stir and reducing the heat slightly if it bubbles too vigorously. Remove from the heat. This brief boil dissolves the sugar and develops a buttery caramel flavor without reducing the mixture into a stiff candy.
Step 7: Beat the frosting until creamy
Let the caramel base cool in the saucepan for 10 minutes; it should still be warm and fluid, not fully cooled. Transfer to a heatproof mixing bowl. Add the sifted powdered sugar in two additions, beating on low speed until incorporated.
Add the vanilla and salt, then beat on medium-low speed for 30 to 60 seconds, just until smooth and spreadable. The frosting should fall from the beaters in thick ribbons. If it is unusually loose, let it stand for 1 to 2 minutes and stir again. Avoid prolonged beating, which can make it set before you have spread it.
Step 8: Frost, slice, and serve
Immediately spoon the warm frosting over the completely cooled cake. Spread it gently to the edges with an offset spatula or the back of a spoon, leaving soft swoops on top. Work promptly and avoid repeatedly smoothing areas that have begun to set.
Let the frosting set for 10 minutes. It should develop a delicate surface crust while remaining creamy underneath. Cut the cake into 15 pieces, arranging the cuts in 3 rows by 5 columns. Serve plain so the fragrant cake and buttery frosting can shine.
Pro Tips
- Choose smooth, unsweetened applesauce: Sweetened applesauce adds extra sugar, while chunky applesauce changes the cake’s texture. If your applesauce has separated, stir it thoroughly before measuring.
- Measure flour lightly: Weighing is most reliable. If using cups, spoon in the flour and level it rather than scooping directly from the bag.
- Keep the cloves modest: The measured 1/4 teaspoon gives warmth without overpowering the applesauce and vanilla.
- Do not overbake: A few moist crumbs on the tester are welcome. Waiting for a completely dry tester can leave the edges less tender.
- Have everything ready for the frosting: Sift the powdered sugar and set out your spatula before cooking the caramel base. If the finished frosting becomes too stiff, stir in warm cream 1 teaspoon at a time, using up to 1 tablespoon as needed.
Variations
- Walnut or pecan cake: Fold 1/2 cup (60 g) chopped walnuts or pecans into the finished batter. Keep the frosting smooth, or sprinkle an additional 2 tablespoons of chopped nuts over it before it sets.
- Raisin spice cake: Soak 1/2 cup (75 g) raisins in warm water for 10 minutes. Drain thoroughly, pat dry, and fold into the batter just before spreading it in the pan.
- Gentler spice blend: Reduce the cloves to 1/8 teaspoon and the nutmeg to 1/4 teaspoon, keeping the cinnamon at 2 teaspoons.
Storage & Make-Ahead
Refrigerate: Cover the frosted cake tightly and refrigerate for up to 4 days. Let individual slices stand at room temperature for 30 minutes before serving for a softer crumb and creamier frosting. Keep the cake out of the refrigerator for no more than 2 hours at a time.
Make ahead: Bake the cake 1 day before serving. Once completely cool, cover and refrigerate it unfrosted. Bring it to room temperature before making and applying the frosting. For the easiest spreading, prepare the frosting immediately before you need it rather than storing it separately.
Freeze: Freeze tightly wrapped, unfrosted cake or individually wrapped frosted slices for up to 2 months. For frosted slices, freeze uncovered for 1 hour to firm the topping before wrapping. Thaw overnight in the refrigerator, then let stand at room temperature for 30 minutes before serving.
