Double Chocolate Mocha Trifle

1 (18.25 ounce) package brownie mix (plus ingredients to make brownies)
1 3/4 cups cold milk
2 (3.4 ounce) packages white chocolate instant pudding and pie filling
1/4 cup warm water
4 teaspoons instant coffee granules
2 cups thawed frozen whipped topping
3 (1.5 ounce) toffee bars, coarsely chopped

Lightly spray a 9 x 13-inch pan with oil.

Prepare and bake brownie mix according to cake-like package directions; cool completely.

In a large bowl, whisk pudding mix into milk until mixture begins to thicken.

Dissolve coffee granules in warm water, add to pudding mixture, mixing well. Fold in whipped topping. Cut brownies into 1-inch cubes. Chop toffee bars. Layer 1/3 of the brownie cubes into the bottom of a bowl. Top with 1/3 of the pudding mixture, pressing lightly, and 1/3 of the chopped toffee. Repeat layers two more times. Chill 30 minutes before serving.
