Preheat oven to 350 degrees. In a mixing bowl, whisk together flour, baking powder, baking soda and salt, set aside. In a large mixing bowl, using an electric hand mixer set on medium-high speed, blend together butter, granulated sugar and orange zest until pale and fluffy, about 3 - 4 minutes. Mix in eggs one at time, blending until combine after each addition. Measure out cream into a liquid measuring cup, stir in orange juice, orange extract and vanilla extract. With hand mixer set on low speed and working in 3 separate batches, blend in flour mixture alternating with cream mixture, beginning and ending with flour mixture and mixing just until combine after each addition. Divide batter among 14 paper lined muffin cups, filling each cup 3/4 full. Bake in preheated oven 23 - 25, rotating muffin tins once halfway through baking, until toothpick inserted into center comes out clean. Remove from oven and allow to cool several minutes before transferring to a wire rack to cool. Cool completely then frost with Vanilla Buttercream Frosting and garnish with an small orange slice if desired (just before serving). Store in an airtight container at room temperature.
*If you want the pilled high amount of frosting then you will likely want to make about 3/4 of the Vanilla Buttercream recipe. If you don't want a ton of frosting then 1/2 of the recipe should be enough.
