Preheat oven to 350F degrees. In large bowl, whisk together flour, baking soda, salt, cinnamon and cardamom.
In another bowl, beat butter, brown sugar and honey with electric mixer until light and fluffy. Add eggs, one at a time, beating after each addition. With mixer on low, gradually add flour mixture. Beat until just combined. Beat in applesauce.
Coat a 9-inch tube pan with nonstick spray. Pour batter in pan; smooth top with spoon. Bake until a toothpick inserted in center comes out with only a few crumbs - about 50 to 60 minutes.
Cool on a wire rack for 10 minutes. Turn onto pan or baking sheet. Cool completely and dust with confectioners' sugar before serving.
