Best Blondies

I found this recipe on a friend's blog, and just had to try them. I made mine with 1/2 cup white chocolate chunks and 1/4 cup toffee pieces.

Basic Blondies
6-7 TBS butter, melted
1 cup brown sugar
1 egg
1 tsp. vanilla extract
1/4 tsp salt1 cup flour
1/4 tsp baking powder (optional, creates lighter Blondie texture)

1. Preheat oven to 350F.
2. Line an 8x8 pan with foil and lightly spray with PAM.
3. In a large microwave safe mixing bowl melt the butter.
4. Allow to cool for 5 minutes.
5. Mix the brown sugar with the melted butter and beat until smooth.
6. Beat in egg and then vanilla.
7. Add salt, stir in flour and baking powder (if using).
8. Mix in any additions (some ideas below).
9. Pour into prepared pan and use a greased spatula to evenly spread mixture in pan and level the top.
10. Bake for 20-25 minutes or until set in the middle. (I baked for 22 minutes) Cool on rack before cutting.

Add in ideas:
1/2 to 1 cup chocolate chips, peanut butter chips, white chocolate or butterscotch chips
1/2 cup chopped pecans, walnuts, almonds
1/2 cup M&M candies
1/2 chopped Reese's PB cups
1/4 cup toffee pieces
1/2 tsp mint extract in addition to, or in the place of vanilla extract
