Step‑by‑Step Instructions for Orange Creamsicle Cake
Step 1: Preheat Oven
Begin by preheating your oven to 350°F (175°C). While the oven heats, prepare two 8 or 9-inch round cake pans by spraying them with non-stick spray. For added security against sticking, you can also line the bottoms with parchment paper. This preparation ensures that your Orange Creamsicle Cake will release effortlessly after baking.
Step 2: Mix Cake Batter
In a large mixing bowl, combine the Duncan Hines Orange Supreme Cake Mix, instant vanilla pudding mix, canola oil, milk, orange zest, and eggs. Using an electric mixer, beat the mixture on medium speed for about 3 minutes, or until it becomes smooth and well-combined. The batter should appear fluffy and have a vibrant orange color, which sets the foundation for your delightful cake.
Step 3: Bake Cake
Divide the cake batter evenly between the prepared pans and smooth the tops with a spatula. Place the pans in the preheated oven and bake for 30 to 45 minutes. Check for doneness by inserting a toothpick into the center of the cakes—if it comes out clean, they’re ready! Allow the cakes to cool for about 10 minutes in the pans, then transfer them to a wire rack to cool completely.
Step 4: Prepare Mousse Filling
While the cakes cool, create the mousse filling by combining instant pudding mix, heavy whipping cream, and orange curd in a clean mixing bowl. Beat the mixture on high speed until it thickens and becomes light and fluffy, about 2-3 minutes. If the consistency is too thick, add small amounts of cream until you achieve your desired texture. Chill the mousse in the refrigerator to firm up while the cakes are cooling.
Step 5: Make Frosting
Once the cakes have cooled completely, prepare the orange vanilla buttercream frosting. In a mixing bowl, beat room temperature unsalted butter until creamy and light. Gradually add in confectioners’ sugar, followed by orange juice or extract and 2 tablespoons of heavy cream. Mix on medium speed until the frosting is smooth and spreadable, adjusting with more cream or sugar as needed to reach the perfect consistency.
Step 6: Assemble Cake
To assemble your Orange Creamsicle Cake, place one layer of the cooled cake onto a cake plate. Use a piping bag or a spatula to create a ring of frosting around the edges. Fill the center with the chilled orange cream mousse, evenly spreading it out. Carefully place the second cake layer on top, ensuring it sits flat. Then, frost the top and sides of the cake with the orange frosting for a beautiful finish.
Step 7: Decorate
Get creative with the decorations! Optionally, use additional colored frosting to pipe swirls or designs on top. You can also garnish with fresh orange slices or colorful sprinkles for an extra festive look. Your Orange Creamsicle Cake is now ready to shine at your gathering, embodying the joys of summer!

Expert Tips for Orange Creamsicle Cake

Cooling Cakes: Let your cakes cool completely before frosting; otherwise, the frosting may melt and slide off. A well-cooled cake helps set that perfect finish!

Orange Creamsicle Cake Recipe FAQs
How do I choose the right oranges for this cake?
Absolutely! When selecting oranges, look for ones that are firm, smooth, and free from dark spots. The skin should feel slightly heavy for its size, indicating juiciness. Navel oranges are a great choice as they have a sweet flavor perfect for baking. It’s best to use fresh ones rather than those sitting around for too long!
How should I store the Orange Creamsicle Cake?
Very! If your cake is unfrosted, store it covered at room temperature in an airtight container for up to 2 days. Once frosted, keep it in the refrigerator covered to maintain its fresh taste, and it will last up to 3 days. Make sure it’s tightly covered to prevent it from drying out!
Can I freeze the Orange Creamsicle Cake?
Yes, you can! For optimal freezing, wrap the unfrosted cake layers tightly in plastic wrap and then in aluminum foil. This ensures they don’t get freezer burn. They can remain in the freezer for up to 1 month. When you’re ready to enjoy, simply thaw at room temperature before frosting and serving.
What if my mousse filling turns out too thick?
No worries! If your mousse filling is thicker than desired, simply add a tablespoon of heavy cream at a time, re-mixing on medium speed until you reach the desired consistency. It should be fluffy yet spreadable. The mousse should complement the cake beautifully, so take your time adjusting!
Are there any allergy concerns I should consider?
Yes! Be cautious with your ingredient choices, especially if making this cake for guests. The recipe contains eggs, dairy (from the butter and cream), and gluten (from the cake mix). If you’re cooking for someone with allergies, consider substitutes like egg replacers, gluten-free cake mixes, and non-dairy alternatives for milk and cream. Personal touches like these ensure everyone can enjoy this delightful Orange Creamsicle Cake!
Can I replace the orange curd, and what are my options?
Absolutely! If you can’t find orange curd, feel free to use orange extract or even vanilla extract as a substitute. If using extract, you might want to add a couple of extra tablespoons of sugar for sweetness, as curd provides both flavor and a bit of moisture. Your mousse will still be delicious and vibrant without it!
