Caramel Pretzel Brownies!

For the brownies:
10 T. melted butter
2 eggs
3/4 c. sugar
1/4 c. brown sugar
4 T. brewed coffee
1 T. vanilla extract
3/4 c. cocoa powder
1/4 t. salt
1/2 c. flour
1 c. pretzels

For the caramel sauce:
2 T. butter
1/2 c. brown sugar
1 t. salt
1 t. vanilla extract
1/4 c. heavy cream

Melt the butter and let it cool before adding eggs, sugar, coffee, and vanilla.  Whisk to combine.  Add cocoa powder and salt and whisk until smooth.  Add flour and stir just until combined.  Spread batter into a greased 9x9 inch baking pan.  Add pretzels on top of the batter.  Meanwhile, heat caramel sauce ingredients in a small saucepan and whisk for 5 minutes.  Drizzle caramel sauce over the pretzels.  Bake brownies at 350 degrees for 26-28 minutes.  Let cool before slicing with a serrated knife.
