“There’s always room for dessert—especially when it’s this eye-catching angel food cake roll. We like strawberry yogurt in the filling, but different flavors work well, too.” —Joan Colbert, Sigourney, Iowa
Preheat oven to 350°. Line an ungreased 15x10x1-in. pan with parchment.
Prepare cake batter according to package directions. Transfer to prepared pan. Bake until top springs back when lightly touched, 15-20 minutes. Cool 5 minutes. Invert onto a tea towel dusted with confectioners' sugar. Gently peel off paper. Roll up cake in the towel jelly-roll style, starting with a short side. Cool completely on a wire rack.
Whisk together yogurt, pudding mix and, if desired, food colouring. Fold in whipped topping.
Unroll cake; spread yogurt mixture over cake to within 1/2 in. of edges. Roll up again, without towel. Cover tightly and freeze. Remove from freezer 30 minutes before slicing.
