Ingredients

1 cup (2 sticks) unsalted butter, room temperature 

1/4 cup vegetable shortening 

1 cup packed light-brown sugar 

3/4 cup granulated sugar 

2 large eggs 

1 teaspoon vanilla extract 

2 cups all-purpose flour 

2 1/2 cups rolled oats 

1 cup dried dates, chopped into 1/4-inch pieces 

1/2 teaspoon baking soda 

1/2 teaspoon salt 

1/2 teaspoon ground cinnamon 

Preparation

Preheat oven to 375 degrees. In a large bowl, beat butter and shortening with a wooden spoon or electric mixer until smooth. Add both sugars, and beat until smooth. Beat in eggs, one at a time, until incorporated. Beat in vanilla.

Combine the remaining ingredients in a separate bowl. Gradually add dry ingredients to the butter mixture, mixing until just combined.

Drop batter by the tablespoon about 1 1/2 inches apart on ungreased baking sheets. Bake until golden brown, about 12 to 14 minutes. Transfer cookies to wire racks to cool.
