Grease and flour a 9″ x 9″ baking pan. Heat oven to 350 degrees F.
In a large bowl with electric mixer, beat butter and sugar until well blended—about 2 minutes. Scrape down sides of bowl and beat in egg and vanilla until combined. Beat in pumpkin puree.
In a medium bowl, stir together flour, baking powder, ginger, salt, and cloves. On low speed, add flour mixture to pumpkin mixture just until combined. Stir in pecans and currants. Spread batter evenly in prepared pan.
Bake 35 minutes or until tester inserted in center comes out clean. Cool completely before cutting into 9 squares. Store in an airtight container in the refrigerator.
