Hazelnut Praline Layer Cake: A Symphony of Sweetness and Crunch

The aroma of toasted hazelnuts always transports me back to my grandmother’s kitchen. She had a small hazelnut tree in her backyard, and every autumn, the entire family would gather to harvest the nuts. We’d spend hours shelling and roasting them, the air filled with their warm, earthy fragrance. While she made many things with the bounty, her hazelnut cake, with its delicate crumb and nutty buttercream, was always the star. This recipe, inspired by those cherished memories, elevates the classic with a sophisticated praline buttercream, creating a truly unforgettable dessert.

Ingredients

For the Cake:

• Nonstick cooking spray
• 2 cups cake flour
• 1 1/2 teaspoons baking powder
• 1/4 teaspoon baking soda
• 1/4 teaspoon salt
• 3/4 cup unsalted butter, at room temperature
• 1 1/4 cups sugar

For the Praline Buttercream:

• 1 1/4 cups sugar
• 4 large egg whites

• 3/4 lb unsalted butter, at room temperature
• 1/4 cup praline paste

Optional Decoration:

Equipment Needed

• Two 9-inch cake pans
• Parchment paper
• Electric mixer (stand or hand-held)
• Sifter
• Small saucepan
• Candy thermometer
• Serrated knife
• Cooling rack

Instructions

1. Prepare the Oven and Pans: Set a rack in the middle of the oven and preheat to 375 degrees Fahrenheit (190 degrees Celsius). Lightly coat two 9-inch cake pans with nonstick vegetable spray. Line the bottom of each pan with a circle of baking parchment to prevent sticking.

2. Sift the Dry Ingredients: In a large bowl, sift together the cake flour, baking powder, baking soda, and salt three times. This ensures a light and airy cake texture.

3. Cream Butter and Sugar: In the bowl of an electric mixer fitted with the paddle attachment, beat the butter and sugar at high speed for 15 seconds, until just combined.

4. Add Eggs: Add the eggs one at a time, beating until each is fully incorporated.

5. Whip Until Light and Fluffy: Continue beating on high speed until the mixture is light and fluffy, about 6 minutes more. This step is crucial for creating a tender cake crumb. Don’t skimp on the beating time!

6. Incorporate Dry and Wet Ingredients: With the mixer on its lowest setting, gradually beat in one-third of the flour mixture. Then, beat in half of the buttermilk and all of the Frangelico. Next, add the hazelnuts and another one-third of the flour mixture. Finally, beat in the remaining buttermilk and the remaining flour. Be careful not to overmix; mix only until just combined.

7. Bake the Cakes: Spread the batter evenly into the prepared pans. Bake for about 20 to 25 minutes, or until the cakes are golden brown, the center springs back when lightly pressed, and a cake tester inserted into the center comes out clean. Start checking for doneness around the 20-minute mark.

8. Cool the Cakes: Set the pans on a rack to cool. Turn out the cakes when cool enough to handle. For easier frosting, refrigerate the cakes for 2 hours after they have cooled to room temperature. This allows them to firm up and prevents them from crumbling during frosting.

9. Prepare the Praline Syrup: While the cakes are cooling, prepare the praline buttercream. Put 1/2 cup water and the sugar in a small saucepan fitted with a candy thermometer. Over high heat, bring the temperature to 240 degrees Fahrenheit (115 degrees Celsius), which is the soft-ball stage.

10. Whisk Egg Whites: In the meantime, in the completely clean and dry bowl of an electric mixer, whisk the egg whites, salt, and cream of tartar until creamy, foamy, and barely able to hold very soft peaks. Make sure there is no grease or yolk in the bowl, or the egg whites won’t whip properly.

11. Drizzle in Syrup: With the mixer running on slow speed, carefully drizzle in the hot syrup in a thin stream. Avoid pouring the syrup directly onto the whisk, as it may splatter.

12. Whip to Stiff Peaks: Continue to whisk on high speed until the mixture is fluffy, firm, and cooled to room temperature. This process can take several minutes. The bowl should no longer feel warm to the touch.

13. Incorporate Butter and Praline Paste: Gradually beat in the butter, a few tablespoons at a time, until fully incorporated. Then, beat in the praline paste until smooth. If the buttercream appears curdled at any point, continue beating until it comes back together.

14. Assemble the Cake: When the cakes are cold, trim the tops with a large serrated knife to create a flat surface. Split each cake into two layers, creating a total of four layers.

15. Frost and Decorate: Spread a 1/4-inch layer of the praline buttercream between each layer. Frost the outside of the cake with the remaining buttercream. Then, coat the sides of the cake with the coarsely chopped hazelnuts. Decorate the top of the cake with whole hazelnuts, blackberries, or raspberries to form a row around the edge, if desired.

Expert Tips & Tricks

• Toasting Hazelnuts: Toasting hazelnuts brings out their rich, nutty flavor. Spread them on a baking sheet and bake at 350°F (175°C) for 6-8 minutes, or until fragrant and the skins begin to crack. Let them cool slightly, then rub them in a clean kitchen towel to remove the skins.
• Making Praline Paste: Praline paste can be found at specialty baking stores or online. If you’re feeling ambitious, you can make your own by caramelizing sugar and combining it with toasted hazelnuts in a food processor.
• Cake Flour Substitute: If you don’t have cake flour, you can make a substitute by using all-purpose flour and removing 2 tablespoons of flour per cup. Replace those 2 tablespoons with cornstarch. This will help create a more tender cake.
• Evenly Filling Cake Pans: To ensure that your cake layers are even in size, use a kitchen scale to measure the batter as you divide it between the cake pans.

Serving & Storage Suggestions

Serve the Hazelnut Praline Layer Cake chilled or at room temperature. The cake is best enjoyed within 2-3 days of baking. Store leftover cake in an airtight container in the refrigerator for up to 5 days. For longer storage, you can freeze the cake for up to 2 months. Thaw in the refrigerator overnight before serving.

FAQs (Frequently Asked Questions)

Q: Can I make the cake layers ahead of time?
A: Yes, you can bake the cake layers a day or two in advance. Wrap them tightly in plastic wrap and store them at room temperature or in the refrigerator.

Q: Can I freeze the entire assembled cake?
A: Yes, you can freeze the assembled cake. Place it in the freezer for about an hour to allow the frosting to firm up, then wrap it tightly in plastic wrap and aluminum foil. Thaw in the refrigerator overnight.

Q: What is praline paste, and where can I find it?
A: Praline paste is a smooth paste made from caramelized sugar and nuts, typically almonds or hazelnuts. You can find it at specialty baking stores or online.

Q: My buttercream looks curdled. What did I do wrong?
A: Buttercream can sometimes look curdled if the butter is too cold or if it is whipped too quickly. Continue beating the buttercream on medium speed, and it should eventually come back together. If it doesn’t, try gently warming the bowl over a double boiler for a few seconds, then beat again.

Q: Can I use a different type of nut instead of hazelnuts?
A: Yes, you can substitute the hazelnuts with other nuts, such as almonds, pecans, or walnuts. Just be sure to adjust the roasting time accordingly.
