Ideas for dessert add-ins

Dear Dessert Diva:
Sometimes my desserts are too hum-drum. What can I do to impress my friends, without spending a lot of extra time preparing the sweets?

Dear Bothered by Brulee:
Simple additions can go a long way.
For example-

Peanut Butter Cookies-
Cinnamon(enough to make a difference)

Brownies-
Mint Chocolate Chips or Reeses Peanut Butter Cups(broken-up.)

Chocolate Cake-
Crumbled mixture of shredded coconut, nuts, and semi-sweet chocolate chips, for topping.

Cheesecake (plain)-
Raspberry jam, swirled in.

Carrot Cake-
Crushed Pineapple (decrease wet ingredients to compromise.)

S'Mores-
Caramel Sundae Sauce (add after marshmallow is roasted.)

Frozen Bananas-
Roll in Marshmallow Creme, walnuts, and drizzle with hot fudge.
