White Cupcakes

1 ½ cups all-purpose flour

1 tsp salt
½ cup unsalted butter, at room temperature
¼ cup vegetable oil
1 ½ cups granulated sugar
1 tsp vanilla extract
1 cup whole milk
5 egg whites

In a mixing bowl (if using a stand mixer use the paddle attachment), cream butter and sugar until light and fluffy, about 3 minutes.
Add vanilla extract and beat until incorporated.
In a liquid measuring cup, combing vegetable oil and milk.
Add flour mixture and milk/oil mixture alternatively to the mixing bowl. Beating on low speed after each addition.
Pour mixture into a large bowl. Scrape down to make sure you get all of the batter.
Clean out bowl and switch to whisk attachment.
Beat egg whites until stiff peaks form.
Fold 1/3 of the egg whites into the batter, to “lighten” the batter. Gently fold in the remaining egg whites.
Grease and lightly flour muffin pans. Fill each cup half full.
Bake at 375 degrees for 18 to 20 minutes or until done.
Cool on a wire rack.

Espresso Chocolate Mousse

2 cups chilled heavy cream
4 large egg yolks
4 TBSP sugar
2 tsp espresso powder
8 oz fine-quality semisweet chocolate, finely chopped

Heat ¾ cup cream in a 1-quart heavy saucepan until hot.
Whisk together yolks, sugar, espresso powder, and a pinch of salt in a metal bowl until combined well, then add hot cream in a slow stream, whisking until combined.
Transfer mixture to saucepan and cook over moderately low heat, stirring constantly, until it registers 160°F on thermometer. Pour custard through a fine-mesh sieve into a bowl.
Melt chocolate in a double boiler, stirring frequently. Whisk custard into chocolate until smooth, then cool.
Beat remaining 1 ¼ cups cream in a bowl with an electric mixer until it just holds stiff peaks. Whisk one fourth of cream into chocolate custard to lighten, then fold in remaining cream gently but thoroughly.

Mascarpone Frosting

2 cups heavy whipping cream
8 ounces Mascarpone cheese, at room temperature
1 ½ cups powdered sugar

Using and electric mixer, whip the cream until stiff peaks form.
In a mixing bowl, fold 2/3¢â¬â„¢s of the whipped cream into the Mascarpone cheese, along with the powdered sugar.
Add remaining cream. Blend until cream is fully incorporated.
Place in refrigerator until ready to frost.

Assemble:
Using the cone method, fill cupcakes with Espresso Chocolate Mousse filling. Place top back on top of cupcakes. Brush top of cupcake with coffee or espresso. Go light on this as they are fresh cupcakes, and not hard like most ladyfingers. You don’t want to soak them.
Frost top with Mascarpone Frosting.
Sprinkle cocoa powder on top of cupcakes and garnish with crushed ladyfingers."
