Preheat oven to 350ºF. Grease a 9- x 13-inch pan and set aside.
In the bowl of an electric mixer, beat together margarine and sugar until creamy. Add eggs, one at a time, beating well to combine after each addition. Add vanilla and baking powder and beat to combine.
With the mixer on low speed, beat in 1 cup flour, followed by liqueur. Beat in 1 additional cup flour, then half of the milk. Beat in remaining flour and milk. Pour batter into prepared pan and bake for 1 hour.
Prepare the whipped cream:
In the bowl of an electric mixer, using a whisk attachment, beat whipped topping until stiff.
Using a rubber spatula, stir in confectioners’ sugar and liqueur, being careful not to over mix.
Prepare the crunch:
Preheat oven to 375ºF.
In a large bowl, combine oats, walnuts, brown sugar, and vanilla. Spread on a baking sheet and bake for 10 minutes.
Assemble:
Either cut small rounds of cake the size of your bowls/cups, or crumble the cake and spread a small amount of crumbs at the bottom. Add a layer of the whipped cream, followed by a small amount of the granola crunch. Repeat all layers until cups are full. To keep the trifles neat, add the whipped cream using a piping bag.
Plan Ahead:
These trifles can be frozen, fully assembled, airtight.
