As a meticulous planner, I often sit down to map out my editorial calendar months in advance, detailing every recipe I intend to create and share. Yet, some ideas simply refuse to wait. They spark to life in my mind and demand immediate attention, often sending my carefully crafted schedule completely out the window. This Allergy-Friendly Halloween Cake was precisely one of those irresistible, spontaneous baking urges.

Just yesterday, while enjoying a scroll through Instagram (a common pastime when one is, perhaps, avoiding laundry), I stumbled upon a truly captivating cake concept. It featured a striking black and orange design, perfect for Halloween, but as is often the case, it was unfortunately laden with eggs, wheat, and dairy – ingredients that are off-limits for many families, including my own.

Now, I’ll be honest: layered cakes aren’t my usual go-to. If you’ve followed my blog, you’ll notice they don’t make frequent appearances. I’ve always found the process of frosting the sides to be quite finicky and time-consuming, often feeling like more effort than it’s worth when compared to the simplicity of cupcakes. (Yes, I am unequivocally a big fan of the humble cupcake!) However, this particular design caught my eye for a compelling reason: it only required frosting between the layers, eliminating the need to fuss with the outer sides.

The moment I realized I could achieve such a festive, multi-layered look by *only* filling the middle, I felt an undeniable surge of baking energy. It was the kind of urgent creative burst that says, “Laundry can wait! The rest of my to-do list is optional! This cake MUST be conquered THIS VERY MOMENT!” (These delightful, slightly chaotic moments happen more often than I’d like to admit, but they often lead to the best recipes!)

And just like that, I plunged into a flurry of activity in my kitchen. It’s truly amazing how quickly I can “find” time for a creative project once I’ve decided I *really* want to make something. If only that same motivation applied to cleaning up afterwards – I can never seem to locate those extra hours for tidying, ha! What made this particular cake so enticing, beyond the minimal frosting, was the fact that I already had two tried-and-true recipes ready to go: my incredibly popular allergy-friendly chocolate cake recipe and my luxuriously silky smooth dairy-free vanilla frosting. This meant I could bypass the stressful experimentation phase, confident that the cake would turn out beautifully, just as my established recipes always do.

Now, let’s address the questions I anticipate you might have about making this delightful, allergy-friendly Halloween creation!

FAQ ON HOW TO MAKE THIS ALLERGY FRIENDLY HALLOWEEN CAKE:

What food coloring do you use? My confession: I used to reach for Wilton’s food coloring gels without a second thought, long before I became diligent about checking every label for hidden allergens. It’s easy to overlook that food coloring might contain unexpected ingredients! While I have contacted Wilton in the past, and a representative informed me they now add a “may contain” label if cross-contamination is a risk in their facility, always exercise caution. We have personally used their gels without issues, but it is absolutely essential to only use what you are comfortable with given your specific food allergies and to follow your allergist’s advice. I’ve also heard excellent things (though I haven’t personally tried them) about AmeriColor’s allergy-friendly food gels. Regardless of the brand, remember that you’ll need a good amount of red to achieve a true, vibrant red – otherwise, you might end up with pink! For this festive Halloween cake, I used about 1/4 teaspoon of orange gel to achieve that bright, classic Halloween orange hue.
Did you use black food coloring in the cake itself? No, I deliberately chose not to add black food coloring to the cake batter. My goal was to minimize the amount of food dye in the cake. Fortunately, the chocolate cake base, especially if you use brown rice flour, already achieves a wonderfully deep, rich, and naturally dark color. However, if you’re aiming for an even more intense black cake for an extra spooky effect, you are absolutely welcome to add some black food coloring gel to your cake batter.
What cake pans do you recommend for this recipe? I personally love the look of a taller cake, but to ensure this recipe was approachable and didn’t leave us with cake for an entire week, I opted for smaller 6-inch cake pans. This allowed me to create a beautiful, multi-layered cake using just one batch of the cake recipe. If you desire an even taller, more dramatic cake, you can easily double the cake recipe. For this cake, I used these reliable Wilton cake pans, which worked perfectly to achieve a satisfying height.
How did you frost this cake without being a cake decorator? This is where the magic of “no special tools” comes in! I’m certainly not a professional cake decorator, nor do I aspire to be one. My mission with this cake was to prove that anyone could create a cute, stacked cake using only everyday kitchen items. For my frosting bag, I simply used a sturdy quart-sized Ziploc freezer bag and snipped off a small corner. I piped the frosting onto the layers in a circle, and then used the flat, unsharp side of a large kitchen knife to gently smooth it out. Voila! To clean up any excess frosting that might have squeezed out between the layers, I grabbed a clean dish scraper – honestly, I just looked around for anything flat and firm! You truly can use any kitchen utensil with a flat edge to achieve a neat finish.
Can I use regular soy shortening in the frosting if I don’t have a soy allergy? Absolutely! My recipe suggests Spectrum shortening specifically for those who need to avoid soy. However, if soy isn’t an issue for you, feel free to use your preferred regular soy shortening.
Can I omit the coconut oil in the frosting if I have a coconut allergy? Yes, you can. If you need to avoid coconut, simply replace the coconut oil with an equal amount of additional shortening to maintain the frosting’s consistency and texture.
Can I use regular wheat flour if I don’t have a wheat allergy? Yes, absolutely. If you don’t have a wheat allergy, you can substitute regular all-purpose flour for the gluten-free flour blend on a 1:1 basis. When doing so, remember to omit the xanthan gum, as it’s typically included in gluten-free baking to provide structure that wheat flour naturally possesses.
What can I use instead of dairy-free sour cream in the cake recipe? Dairy-free sour cream can sometimes be a bit tricky to find in all grocery stores. A fantastic and widely available alternative is unsweetened applesauce. In fact, for the cake featured in these pictures, I actually used applesauce because I had run out of dairy-free sour cream! It works wonderfully to keep the cake moist and adds a subtle tang.
Did you use a cake turntable for frosting? As I mentioned earlier, this cake is all about using typical kitchen tools! I simply placed the cake on the plate you see in the pictures and rotated it by hand as I worked. You absolutely don’t need any fancy equipment to achieve a beautifully layered cake, and that’s precisely why I love this recipe so much. It’s accessible to everyone!
If you had to pick one “special” tool, which would you recommend? While this cake is designed to be made without specialized tools, if I were to recommend one item that significantly improves frosting any baked good, it would be an offset spatula. I’ve owned mine for years, and I use it constantly for frosting cookies, bars, and cakes. Its angled blade makes spreading frosting incredibly easy and smooth, truly making it an indispensable tool in my kitchen.
The original recipe is for cupcakes – do I do anything different to turn it into cakes? Surprisingly, no! The beauty of this versatile recipe is that the batter works perfectly for both cupcakes and cakes. The only adjustment you need to make is the baking time. For cakes, simply bake for approximately 22-25 minutes, or until a toothpick inserted into the center comes out clean and the edges are set. It bakes up beautifully either way!

Ingredients

One recipe for allergy-friendly chocolate cupcakes
One recipe for dairy-free vanilla frosting
Two 6″ cake pans
Gallon quart ziploc baggie
Orange food coloring gel

Instructions

Preheat your oven to 350 degrees F (175 degrees C).
Grease extremely well two 6-inch round cake pans. For best results, consider lining the bottoms with parchment paper.
Follow the instructions for the allergy-friendly chocolate cupcake recipe linked above. Once your batter is prepared, divide it evenly and pour into the two greased cake pans.
Bake for 22-25 minutes, or until the edges appear set, and the center springs back gently when lightly touched. A toothpick inserted into the middle should come out clean.
Carefully remove the cakes from the oven and allow them to rest in their pans for five minutes. While they’re resting, gently run a butter knife along the edges of each pan to ensure the cakes are loose.
Flip the cakes out of their pans and invert them onto a cooling rack. To prevent sticking, I often place a sheet of plastic wrap directly onto the cooling rack before adding the cakes.
While the cake layers cool completely (you can place them in the fridge to speed up this process if you’re in a hurry), prepare your dairy-free vanilla frosting. Follow the recipe directions, then add orange food coloring gel to achieve your desired vibrant Halloween hue. I typically make a batch and a half of frosting to ensure I have plenty, preferring to have extra rather than running short, but you can adjust the amount as you like.
Once the cakes are fully cool, if they have domed slightly during baking, carefully level the tops with a serrated knife to ensure they will stack evenly. Then, slice each cake horizontally into two equal discs, giving you four cake layers in total.
Place the first cake disc onto your serving plate. Using a spatula or spoon, transfer a generous amount of the orange frosting into a gallon or quart-sized Ziploc bag. Snip off one corner of the bag to create an impromptu piping bag.
Starting about a 1/2 inch from the outer edge, pipe a thick circle of frosting onto the cake layer, then fill in the rest of the circle. Gently smooth the frosting with the flat side of a knife. By not frosting right up to the edge, you prevent excess frosting from squeezing out when you add the next layer.
Carefully place the next cake disc on top and repeat the frosting process for each subsequent layer. You can choose to leave the top layer as plain cake, or add a final layer of frosting as I did for a finished look.
Keep your beautiful allergy-friendly Halloween cake covered at room temperature or refrigerated until you are ready to serve it to ensure freshness.
