Homemade chocolate whipped cream:
2 cups heavy cream, plus additional to form a paste
¼ cup granulated sugar
3 tablespoon cocoa powder
Optional: ½ teaspoon espresso or ½ teaspoon vanilla extract
Place the cocoa and sugar in a medium mixing bowl. Mix together the sugar and cocoa powder with enough heavy cream to form a paste. (This helps prevent lumps) Add the cocoa paste to the cream. Beat with a mixer until stiff peaks form. Chill until serving.
