Tiger-striped Brownies

Tiger-striped Brownies

1 oz semisweet chocolate

1 oz unsweetened chocolate

1 Tbsp unsalted butter           

⅓ C smooth peanut butter

2 Tbsp vegetable oil

½ C firmly packed brown sugar

½ C sugar

2 large eggs, at room temp

1 ½ tsp vanilla

¾ C flour

¼ tsp salt

Preheat oven to 325º and butter an 8-inch square pan.  In a microwave, melt chocolate and butter on high for 1-2 minutes.  Stir the mixture halfway through.  Set the mixture aside to cool to room temp. 

In medium sized bowl, beat together peanut butter and oil until combined.  Add the sugars and continue beating until the mixture is light and fluffy.  Add eggs, one at a time, beating well after each.  Mix in vanilla and then flour and salt until just combined.

In a small bowl, stir ⅓ cup of the batter with the melted chocolate.  Scrape the remaining batter into the pan and spread evenly.  Spoon the chocolate mixture over the batter.  Using a knife, make a zigzag through the layers to create a marbled effect.  Bake for 30-35 minutes or until toothpick comes out almost clean.  Cool brownies in pan, then cut them into bars.

Makes about 16 bars.
