How to Make The Ultimate Mimosa Cake

Equipment Needed:

Instructions:

Preheat & Prep:

Preheat your oven according to the yellow cake mix instructions.
Grease and flour two 8-inch round cake pans or use my easy Cake Pan Release Recipe. This cake also bakes well in a 9x13-inch sheet pan.
Zest a small orange and squeeze 1/2 cup of the fresh orange juice.

Mix the Cake:

Prepare the yellow cake mix according to the package instructions, but substitute half of the water required with fresh squeezed orange juice. Then substitute the other half of water for whole milk.
Add the orange zest and orange liqueur (Grand Marnier is perfect) into the batter for an extra burst of orange flavor.
Divide the batter evenly between the prepared pans.

Bake:

Bake according to the package’s instructions, or until a toothpick inserted into the center comes out clean.
After baking, let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.

Make the Champagne Buttercream:

While the cakes are cooling, make the champagne frosting. Use an electric hand mixer to beat the softened butter on medium-high speed until creamy, about 2-3 minutes.
Gradually add powdered sugar, 1 cup at a time, beating on LOW until combined. Then, add the champagne and beat on high until the frosting is smooth and spreadable.
If the frosting is too stiff, you can add a bit more champagne (or milk for a non-alcoholic version) until it reaches the desired consistency. If the frosting is too soft, gradually mix in more powdered sugar until it thickens to your liking.

Assemble the Cake:

Once the cakes are cooled, remove them from the pan and level the layers with a serrated knife. Place one cake layer on your serving plate and create a buttercream dam around the edge to contain the filling.
Evenly spread a layer of orange marmalade inside your piped dam with an offset spatula and place the next layer on top.
To prevent crumbs from escaping, apply a thin layer of buttercream all over the cake. For added stability, refrigerate for approximately 10 minutes before frosting the cake with the remaining Champagne Buttercream.
Pop your cake back in the fridge to let everything set.

Time to Decorate:

Once set, garnish with edible gold leaf and fresh orange slices for an elegant finish. If you’re feeling creative, you can even pipe some frosting decorations around the edges.

Serve & Enjoy:

Slice and serve your mimosa cake at room temperature to allow the flavors to shine. It pairs wonderfully with a cup of coffee or, better yet, an actual mimosa!

How Many Servings:

Yields: 12 to 16 servings, depending on how you slice it. This makes it ideal for gatherings, brunches, or a weekend treat with the family.

How to Store Your Mimosa Cake:

To keep this cake as fresh as possible, store it in an airtight container at room temperature for up to 3 days.
- If you're in a warmer climate, consider refrigerating it; just remember to let it come to room temperature before serving to enjoy its full flavor profile.
For longer storage, the frosted cake can be frozen for up to 3 months. Thaw overnight in the refrigerator before serving.

How Long This Recipe Lasts:

Enjoy your Mimosa Cake at its peak within the first 3 days.
If refrigerated, it can last up to 5 days without losing its charm.

Substitutions/Variations:

Non-Alcoholic Version: Substitute champagne in the frosting with non-alcoholic sparkling grape juice.
Gluten-Free Adaptation: Use a gluten-free cake mix to accommodate dietary restrictions without compromising on taste.
Orange Zest Alternative: No orange for zesting? Use a teaspoon of orange extract to keep the citrus vibe alive.

FAQs:

Q: Can I make the cake layers ahead of time?

A: Absolutely! Bake the layers, cool them thoroughly, and wrap them in plastic wrap. They can be stored at room temperature for a day or in the freezer for up to a month.

Q: What can I use if I don’t have champagne for the frosting?

A: While champagne adds a special touch, you can use any sparkling wine or even sparkling cider for a non-alcoholic version. The key is the bubbly texture and slight tanginess.

Q: Can I decorate this cake differently?

A: Yes, the sky’s the limit! While gold leaf and orange slices create an elegant look, feel free to adorn your cake with edible flowers, citrus zest curls, or even a sprinkle of sparkling sugar for a different aesthetic.

Tips & Tricks:

For an extra moist cake, substitute the oil in the box mix with an equal amount of unsalted butter and add an extra egg. This makes the cake richer and more tender.
Ensure the butter for the frosting is at room temperature to achieve a smooth, creamy consistency without lumps.
If using edible gold leaf, apply it with a clean, dry brush for precision and to prevent tearing.
