Raspberry Oatmeal Squares

I made these for a bake sale a few weeks ago, and they were delicious! Today I'm going to substitute the raspberry jam with red plum preserves.

from the JoyOfBaking.com

1/2 c butter, room temperature
1 c light brown sugar
1 large egg
1 tsp. pure vanilla extract
1 1/4 c all-purpose flour
1/2 tsp. baking soda
1/4 tsp. salt
2 c old-fashioned oats, divided
1 c raspberry jam

Preheat oven to 350 degrees, and place rack in middle of oven. Grease a 9x9 baking pan.

With an electric mixer, beat butter and brown sugar until light and fluffy, about 2-3 minutes. Add the egg and vanilla; beat until incorporated.

In a separate bowl, whisk together the flour, baking soda, and salt. Add to the butter mixture, mixing until well-combined. Stir in 1 3/4 c of the rolled oats. Press 2/3 of the dough into the prepared pan. Spread the jam over top.

To the remaining dough, add the remaining 1/4 c of oats. Crumble evenly over the top of the jam. Bake 25-30 minutes, until nicely browned. Place on a wire rack to cool. Cut into squares to serve.
