raspberry swirl brownies

We love these raspberry brownies. They are rich, delicious and do not taste like they came from a mix- but rather like they came from a fancy bakery..I use about 1/2 a 12 oz jar of seedless raspberry jam, instead of just 1/2 a cup,and I use 1/2 cup of chocolate chips- not 1/4 of a cup. One person in my family does not like nuts- so I either leave those out or decorate the top of the frosted brownies with pecan halves so that my daughter who does not like nuts can just pull the nut off before she eats it. I always frost the brownies with the Fluffy Chocolate Frosting on page 408 of this same book. Easy and worth making!
