Chocolate Log Cake
Recipe by Choccywocky
30 min 2 Moderately Sweet Main Ingredient: Sunreap Maida Cuisine: Indian Fusion
For the Chocolate Sponge Cake :
1/4 cup (30 grams) Sunreap Maida
2 tbsp (15 grams) cornstarch
2 tbsp (15 grams) unsweetened cocoa powder
1/8 tsp salt
1/2 cup (100 grams) granulated white sugar, divided
2 large eggs (110 grams without shells)
3 large egg yolks
2 large egg whites
1 tsp(4 grams) pure vanilla extract
1/2 tsp lemon juice
For the Chocolate Frosting (Ganache) :
180 grams semi sweet chocolate, coarsely chopped
60 grams milk chocolate, coarsely chopped
3/4 cup (180 ml) heavy whipping cream
2 tbsp (25 grams) butter, cut into small pieces
For the Chocolate Whipped Cream :
1 cup (240 ml) cold heavy whipping cream
1/2 tsp (2 grams) pure vanilla extract
1/4 cup (50 grams) granulated white sugar
2 tbsp (15 grams) unsweetened cocoa powder
For the Chocolate Sponge Cake:
Step 1Preheat your oven to 450 degrees F (230 degrees C) and place the oven rack in the centre of your oven. Butter or spray with a nonstick vegetable spray. A 17×12 inch (or close to this size) baking pan, line it with parchment paper, and then butter and flour the paper (or spray with a nonstick vegetable/flour spray).
Step 2In a bowl, whisk the flour with the cornstarch, cocoa powder, and salt.
Step 3Next remove 1 tablespoon (15 grams) of the granulated white sugar called for in the recipe and set it aside. It will be added to the whipped egg whites.
Step 4Then place the two eggs and three egg yolks, along with the remaining granulated white sugar and vanilla extract, in the bowl of your electric mixer, fitted with the whisk attachment (can use a hand mixer). Beat on high speed until the mixture is thick, pale yellow, and fluffy (this will take about five minutes). (When you slowly raise the beaters the batter will fall back into the bowl in a slow ribbon.) Sift half the flour mixture over the beaten egg mixture and fold in gently with a rubber spatula, just until the flour is incorporated. Sift the remaining flour mixture into the batter and fold in.
Step 5In a clean bowl, with the whisk attachment, (or with a hand mixer) beat the egg whites and lemon juice, on medium low speed, until soft peaks form. On high speed, gradually add the one tablespoon (15 grams) sugar and beat until stiff peaks form. Gently fold a little of the whites into the batter to lighten it, and then fold in the rest of the whites. Pour the batter into your prepared pan, spreading evenly with an offset spatula or back of a spoon. Bake for about 6 -8 minutes, or until set, and when the top of the cake is lightly pressed, it springs back (a toothpick inserted into the center of the cake will come out clean).Immediately upon removing the cake from the oven, sprinkle the top of the cake with some powdered sugar and then invert the cake onto a clean dish towel (the powdered sugar will prevent the cake from sticking to the towel). Remove the parchment paper, sprinkle the top of the cake with powdered sugar, and gently roll up the sponge cake, with the towel (this helps prevent cracking and sets the log shape). Place on a wire rack to cool.
For the Chocolate Frosting:
Step 1Place the chopped chocolates in a medium sized heatproof bowl. Heat the cream and butter in a small saucepan over medium heat. (Can also heat the cream and butter in the microwave.) Bring just to a boil. Immediately pour the boiling cream over the chocolate and stir gently (as you do not want to incorporate too much air into the mixture) with a spoon or whisk until smooth. Set aside until it thickens to spreading consistency (this may take a couple of hours).
For the Chocolate Whipped Cream:
Step 1In a large mixing bowl, fitted with the whisk attachment (can use a hand mixer), place the whipping cream, vanilla extract, sugar, and cocoa powder and whisk to combine. Then beat the mixture, on high speed, until stiff peaks form. Once the cake has cooled, unroll, spread with the cream and then gently roll the cake back into a log shape.
Step 2Next, cut about a 1 – 1 1/2 inch (2.5 – 3.75 cm) diagonal slice from one end of the cake and, using a little of the frosting, attach it to one side of the cake (so it looks like a tree limb). Then cut a slice straight across the cake (to make the cake even) and again, use a little of the frosting, attach it to the other side of the cake (so you have two tree limbs). Frost the top and sides of the cake with the remaining frosting. If you like you can run the tines of a fork through the frosting so it looks like the “bark” of a tree. Cover and place in the refrigerator until serving. This cake can be stored in the refrigerator for about 4-5 days. Just before serving remove the cake from the fridge, dust the top with powdered sugar (for snow) and decorate with meringue mushrooms, if using.
