Ingredients for amaretto sour cake

Eight layers of flavor: flour, sugar, and boozy richness meet citrus brightness for a cake that balances sophistication with approachability.

The amaretto liqueur is non-negotiable here—Disaronno or Galletto deliver the nutty depth this cake demands. Look for bottles with at least 25% ABV to ensure proper infusion without overpowering. Fresh lemon zest should be vibrant, not dried out—organic lemons from the produce section work best, though conventional will suffice. The butter must be cold when creamed; European-style unsalted butter from Plugrá or Kerrygold adds richness without competing with the amaretto's flavor. For the powdered sugar, Domino brand is ideal—its fine grind prevents graininess in the buttercream.

No amaretto? Substitute 0.25 cup almond extract plus 0.25 cup lemon juice, though the flavor won't be identical. Fresh lemon juice can be swapped for bottled, but add 1 tsp citric acid to mimic brightness. For a lighter texture, replace 0.5 cup flour with cornstarch. The buttercream requires cold cream—chill your bowl and beaters for 10 minutes if your kitchen is warm. If you prefer a less sweet frosting, reduce powdered sugar to 3.5 cups and add 1 tbsp lemon zest for extra zing.

Store cake layers wrapped in plastic in the fridge for up to 3 days—this prevents drying. Assemble the day you serve for optimal texture. The buttercream keeps 5 days refrigerated or 3 months frozen in an airtight container. For make-ahead convenience, bake layers 2 days ahead, cool completely, then wrap individually. Garnish with amaretto-soaked cherries 30 minutes before serving to prevent sogginess—simply brush with reserved liqueur.

Step-by-step instructions for amaretto sour cake

Here's the method for creating a perfectly moist cake with rich amaretto flavor and velvety vanilla buttercream.

Preheat your oven to 350°F and grease two 9-inch round cake pans. Line the bottoms with parchment paper for easy removal. In a medium bowl, whisk together the 2.5 cups all-purpose flour, 2 tsp baking powder, and 0.5 tsp salt. Set aside.

In a large mixing bowl, cream the 1 cup unsalted butter and 2 cups granulated sugar together on medium speed until light and fluffy, about 3-4 minutes. Add the 4 whole large eggs, one at a time, mixing well after each addition. Scrape down the sides of the bowl as needed. Stir in the 0.5 cup amaretto liqueur, 1 tbsp fresh lemon zest, and 0.25 cup lemon juice.

With the mixer on low speed, gradually add the dry ingredients to the wet ingredients until just combined. Avoid overmixing—just until the flour is incorporated. Divide the batter evenly between the prepared cake pans and smooth the tops with a spatula.

Bake the cakes in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean. The cakes should be golden brown on top and spring back when gently pressed in the center. Rotate the pans halfway through baking for even browning.

Once baked, remove the cakes from the oven and let them cool in the pans for 10 minutes. Then, transfer them to a wire rack to cool completely. This cooling step is crucial—it prevents the cakes from becoming soggy when you add the frosting later.

In a large mixing bowl, beat the 1.5 cups heavy whipping cream with an electric mixer on medium-high speed until soft peaks form, about 2-3 minutes. In a separate bowl, combine the 4 cups powdered sugar, 2 tsp vanilla extract, and a pinch of salt. Gradually add the powdered sugar mixture to the whipped cream while continuing to beat.

Beat the mixture on high speed for another 3-4 minutes until smooth, fluffy, and fully incorporated. The buttercream should be thick enough to hold its shape but still spreadable. If it's too thick, you can thin it slightly with a teaspoon of the amaretto liqueur reserved from earlier.

Once the cakes are completely cooled, place one layer on a cake stand or plate. Spread a thin layer of buttercream over the top of the first layer. This is called a "crumb coat" and helps prevent crumbs from getting into the final layer of frosting.

Place the second cake layer on top of the first, aligning the edges carefully. Spread a generous layer of buttercream over the top and sides of the cake, using an offset spatula to create a smooth finish. For a classic look, you can pipe additional buttercream around the base of the cake or create decorative swirls on top.

Arrange the 12 whole maraschino cherries on top of the cake for a festive touch. You can also add them around the base or on the sides for extra decoration. Let the cake sit at room temperature for at least 1 hour before slicing to allow the frosting to set properly.

Slice and serve the cake at room temperature. Each slice should have a moist, tender crumb with a delicate amaretto flavor and a creamy, sweet vanilla buttercream. The lemon zest adds a bright citrus note that balances the richness of the buttercream and the boozy undertones of the amaretto.

Health benefits of this amaretto sour cake

Rich Nutritional Balance

This cake offers a surprisingly balanced nutritional profile for a dessert. The amaretto liqueur provides trace amounts of antioxidants from almonds, while the fresh lemon zest contributes vitamin C and fiber. The whole eggs deliver high-quality protein—about 12 grams per serving—helping satisfy cravings while providing muscle-building benefits. 💪

Moderate Sugar Content

While desserts often get a bad rap for sugar, this recipe uses superfine granulated sugar more efficiently than most cakes. The 2 cups total are distributed across the batter and buttercream, with the tart lemon and nutty amaretto reducing perceived sweetness.

For a lighter option, reduce powdered sugar to 3.5 cups—your guests won't miss the extra sweetness.

Almond Benefits

The amaretto's almond base contributes heart-healthy monounsaturated fats and vitamin E, both of which support cardiovascular function. A 0.5 cup serving of amaretto (used in the cake) provides about 10% of your daily vitamin E needs

The almond flavor also adds complexity that makes the cake feel more sophisticated than traditional vanilla cakes. ✨
