Plum Upside Down Cake Recipe

 Melt 1/4 cup of the butter in small saucepan on medium heat. Add 1/4 cup of the sugar; cook 1 min. or until sugar is completely dissolved, stirring occasionally. Pour into cake pan. Arrange the plums around bottom of pan, sprinkle with almonds. Set aside.
Beat remaining 1/2 cup butter and remaining 3/4 cup sugar in medium bowl with electric mixer until light and fluffy. Add eggs, one at a time, beating well after each addition. Blend in extract. Add flour and baking powder; beat just until blended. Gently spread over plums.
Bake until toothpick inserted in center comes out clean. Immediately run knife or metal spatula around rim of pan to loosen cake; invert onto serving plate. Cool completely before cutting into 12 slices to serve.
