How to Make It
Preheat oven to 350ºF. Coat a 12-cup Bundt pan with baking spray with flour. Beat butter, granulated sugar, brown sugar, and oil with an electric mixer on medium speed until light and fluffy, about 2 minutes. Add eggs 1 one at a time, beating until each is just incorporated.
Stir together yogurt, milk, and vanilla in a small bowl. Whisk together all-purpose flour, whole-wheat flour, baking powder, baking soda, and salt in a medium bowl. Add flour mixture to butter mixture alternately with yogurt mixture in 3 additions, beginning and ending with flour mixture, beating on low speed until flour is just incorporated before the next addition. Pour batter into prepared Bundt pan.
Bake in preheated oven until a wooden pick inserted in center of cake comes out clean, 48 to 50 minutes. Let cake cool in pan on a wire rack 15 minutes. Turn cake out onto wire rack; let cool completely, about 15 minutes. Serve with sliced strawberries.
