1/2 cup creamy peanut butter
16 tablespoons butter
2 tablespoons white sugar
1/2 cup packed light brown sugar
4 tablespoons heavy cream
1 egg
1 (8 ounce) can frozen lemonade concentrate
In a large bowl, cream together peanut butter, butter and white sugar. Beat in the oil and cream. Mix in the lemonade. Spread mixture over a 10x15 inch 18-inch-square baking dish.
Bake in the preheated 350 degrees F (175 degrees C) for 20 to 30 minutes, or until a wooden pick inserted roughly in the centre comes out clean. Allow to cool completely before cutting into squares.
