Making the Dreamy Orange Creamsicle Cake is a delightful process if you follow these straightforward steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
2. Mix Dry Ingredients: In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
3. Cream Butter and Sugar: In a large mixing bowl, beat the softened butter and granulated sugar until light and fluffy.
4. Add Eggs: Add the eggs one at a time, mixing well after each addition.
5. Incorporate Orange Zest and Juice: Stir in the orange zest and juice, mixing until well combined.
6. Combine Mixtures: Gradually add the dry ingredients to the butter mixture, alternating with the milk. Begin and end with the dry ingredients. Mix until just combined.
7. Divide Batter: Pour the batter evenly into the prepared cake pans, smoothing the tops.
8. Bake: Place in the preheated oven and bake for 25-30 minutes. A toothpick inserted in the center should come out clean.
9. Cool the Cakes: Once baked, allow the cakes to cool in their pans for 10 minutes before transferring them to wire racks to cool completely.
10. Prepare the Frosting: In a medium bowl, beat the softened butter until smooth. Gradually add powdered sugar, orange juice, orange zest, and vanilla extract, mixing until creamy.
11. Frost the Cake: Once the cakes are cool, spread a layer of frosting on top of one cake layer, then place the second layer on top and frost the top and sides.
