Peanut Butter Brownies: after you pour the batter into the pan, add a couple of dollops of peanut butter on top and swirl through the batter. You can also add peanut butter chips to the batter instead of the peanut butter (or in addition to, if you're a peanut butter lover!)
Double Fudge Brownies: add 1/2 bag of chocolate chips to brownie batter
Nutty Brownies: add 1/2 bag of nuts to your brownie batter
M&M Brownies: add a cup of M&Ms to your brownie batter (M&M minis are great for this!)
Cheesecake Brownies: mix together 8-oz cream cheese (room temperature), 1/3 cup sugar, 1 large egg and 1/2 tsp vanilla extract, pour over brownie batter and swirl through
Frosted Brownies: bake brownies, then just frost with your favorite frosting!
Turtle Brownies: fold 1/2 cup (or more) chopped pecans into batter, bake, top with more pecans and drizzle with caramel sauce (they also now make caramel chips now that you could add to the batter)
Chocolate Hazelnut Brownies: add a few dollops of Nutella on top of batter and swirl through
I have a few more up my sleeve, but I will make that another post. Don't let your brownies be boring any longer!
