Preheat oven to 375 degrees. Butter and flour 9-inch square baking pan with 2-inch-high sides. Melt 1 1/2 ounces chocolate in top of double boiler set over simmering water, stirring until smooth. Remove from over water. Let cool 10 minutes.

Mix in dry ingredients alternately with buttermilk, beginning and ending with dry ingredients. Add 1/2 cup boiling water and vanilla; stir until blended (batter will be thin).
Pour batter into prepared pan. Bake until tester inserted into center comes out clean, about 35 minutes. Transfer pan to rack and cool completely. (Can be prepared 1 day ahead. Cover with foil and store at room temperature.)
Beat cream in large bowl until stiff peaks form. Spoon 1 1/2 cups whipped cream into bottom of large glass trifle bowl. Sprinkle with 1/2 cup toffee bits. Crumble 1/3 of cake over toffee.
