Chocolate Cake with Milk Chocolate-Peanut Butter Frosting and Peanut Butter Brittle

My Unexpectedly Delicious Eggless Chocolate Cake Adventure

Baking has always been my happy place, a sanctuary where I can lose myself in the rhythmic mixing, the intoxicating aromas, and the sheer joy of creating something delicious from scratch. Lately, I've been experimenting with eggless baking, driven by a combination of curiosity and a desire to expand my culinary repertoire. I never thought I'd achieve the same rich, moist texture of a traditional chocolate cake without eggs, but this recipe proved me delightfully wrong.

The idea came to me on a spontaneous trip to the grocery store. I was aiming for a simple chocolate cake, but a forgotten ingredient list led me down an unexpected path. I didn't have eggs! Instead of abandoning the idea, I decided to improvise. This led me to a recipe that is now a firm family favorite: an eggless chocolate cake with a luxuriously creamy milk chocolate-peanut butter frosting and a satisfyingly crunchy peanut butter brittle topping. The oil in the batter, I discovered, was the key. It not only adds moisture, preventing dryness that can plague eggless cakes, but also lends a delightful tenderness to the crumb. The combination of flour, sugar, cocoa, and a touch of baking soda and salt provides the necessary structure, resulting in a cake that is both light and decadent.

The frosting is another story altogether. The rich, creamy milk chocolate filling acts as a beautiful bridge between the cake layers, offering a hint of sweetness that perfectly complements the peanut butter frosting. I used mascarpone cheese, which adds a remarkable depth and smoothness to the frosting – it is not too sweet, allowing the natural flavour of the chocolate and peanut butter to shine. The final touch? That incredible peanut brittle! This homemade brittle, made with peanuts, sugar, and corn syrup, adds a beautiful textural contrast – a pleasing crunch against the smooth, creamy frosting and tender cake. It's the perfect counterpoint to the richness of the chocolate and peanut butter.

Tips and Variations:

This recipe is remarkably adaptable. Feel free to experiment with different types of nuts in the brittle, such as almonds or cashews. You can also adjust the sweetness of the frosting by adding more or less powdered sugar. If you prefer a more intense chocolate flavor, use dark chocolate instead of milk chocolate for the filling. For a less intense chocolate flavor in the cake, you could reduce the cocoa quantity.

Making it ahead: Both the brittle and the cake can be made ahead of time, making this recipe ideal for entertaining or busy weeknights. The cake is best served at room temperature after chilling. Allow ample time for the cake to come to room temperature before serving to ensure optimal flavor and texture. Let the cake’s flavor develop. The flavour deepens beautifully over time.

More than just a recipe, this cake represents a happy accident, a testament to the power of improvisation in the kitchen. It's a reminder that sometimes, the most unexpected creations can become the most cherished. Give it a try and experience the magic for yourself! It's a recipe that’s guaranteed to impress—and maybe even inspire you to embrace your own culinary spontaneity. The recipe is easy enough for a beginner baker, yet elegant enough for a special occasion.

Step-by-step

• Preparation For brittle: Line large rimmed baking sheet with foil; brush with oil. Bring sugar, corn syrup, and 1/4 cup water to boil in heavy medium saucepan over medium-high heat, stirring until sugar dissolves. Boil without stirring until syrup is deep amber, swirling pan occasionally, about 10 minutes. Immediately stir in peanuts and all remaining ingredients. Scrape out mixture onto prepared sheet; spread out to about 13x9-inch rectangle. Cool completely. Coarsely chop enough brittle to measure 1 cup and finely chop enough to measure 1/2 cup. DO AHEAD: Can be made 3 days ahead. Store in separate airtight containers at room temperature.
• For cake: Preheat oven to 350°F. Spray two 9-inch-diameter cake pans with 2-inch-high sides with nonstick spray. Line pan bottoms with parchment paper. Sift flour, sugar, cocoa, baking soda, and salt into large bowl. Whisk 2 cups water, oil, vinegar, and vanilla in medium bowl to blend. Gradually add water mixture to dry ingredients, whisking until batter is smooth. Divide batter between prepared pans (scant 3 cups each). Bake cakes until tester inserted into center comes out with a few crumbs still attached, about 28 minutes. Cool cakes in pans 15 minutes. Cut around cakes and turn out onto racks. Peel off parchment and cool.
• For filling and frosting: Place chocolate in medium bowl. Bring 5 tablespoons cream just to simmer in small saucepan over medium heat. Pour cream over chocolate; whisk until melted and smooth. Let stand until thick enough to spread, whisking occasionally, about 30 minutes. Beat powdered sugar, 1 1/2 cups chilled cream, and peanut butter in large bowl just until blended. Add mascarpone; beat frosting just until thickened (do not overbeat). Place 1 cake layer, flat side up, on platter. Spread milk chocolate filling evenly over; sprinkle with 1/2 cup finely chopped peanut brittle. Spread with 1 cup frosting. Top with second cake layer, flat side down. Spread remaining frosting over top and sides of cake. Cover with cake dome and chill 1 hour. DO AHEAD: Can be made 1 day ahead. Keep chilled. Let stand at room temperature 2 hours before continuing. Sprinkle 1 cup coarsely chopped brittle over top of cake and serve.
