Each cupcake bakes up moist and rich, featuring deep chocolate flavor you would never guess is vegan, nut-free, egg-free, and dairy-free. They are perfect for parties, classroom treats, or just a safe homemade dessert when allergies are top of mind.
Last Halloween I surprised my son's class with these cupcakes and not a single kid noticed they were allergy-friendly everyone just loved them for their delicious chocolate flavor.
Ingredients
- Gluten-free all-purpose flour blend: gives structure and keeps these safe for gluten sensitivities always pick a brand certified gluten-free for the most reliable results
- Unsweetened cocoa powder: brings deep chocolate flavor opt for Dutch-processed if you want even more intensity
- Granulated sugar: sweetens the cupcakes use organic cane sugar if preferred
- Baking soda: helps the cupcakes rise and stay fluffy check it is fresh by seeing if it fizzes in vinegar
- Salt: balances sweetness and sharpens the chocolate flavor try fine sea salt for even distribution
- Unsweetened oat milk: keeps the batter moist and works well without overpowering the chocolate choose a plain version with few additives
- Vegetable oil: boosts moisture and prevents a dense crumb sunflower or canola both work well just avoid soy-based if allergies are a concern
- Apple cider vinegar: reacts with baking soda to help the cupcakes rise and adds a slight tang
- Pure vanilla extract: rounds out all the chocolate flavors and adds warmth always look for real vanilla rather than imitation
- Allergy-friendly chocolate chips or sprinkles: for a fun finish make sure they align with your allergy needs
- Dairy-free nut-free frosting: to top them off use homemade or double-check ingredient lists on store-bought tubs
- Halloween-themed decorations: for a festive touch plastic toppers or sugar decorations that fit your needs bring these to life
Instructions
- Prepare the Pan:
- Line a standard muffin tin with twelve cupcake liners and heat your oven to 350 degrees Fahrenheit this ensures the cupcakes release cleanly and bake evenly
- Mix Dry Ingredients:
- Whisk together the flour cocoa sugar baking soda and salt in a large mixing bowl combine them thoroughly to distribute leavening and salt evenly throughout the batter
- Combine Wet Ingredients:
- Pour the oat milk oil apple cider vinegar and vanilla into a separate bowl blend well until the mixture looks smooth and slightly creamy
- Make the Batter:
- Add the wet mixture to the dry ingredients Stir slowly by hand until just combined Overmixing creates tough cupcakes so stop as soon as you see no streaks of dry flour
- Fill the Cupcake Liners:
- Spoon the batter evenly into the liners filling each about two thirds of the way to prevent overflow when baking
- Bake the Cupcakes:
- Place the tin in the center of the oven and bake for twenty to twenty two minutes A toothpick pushed into a cupcake should come out clean or with only a crumb or two
- Cool Completely:
- Let the cupcakes rest in the pan for five minutes then carefully remove and transfer to a wire rack Wait until totally cool to avoid melting the frosting
- Decorate for Halloween:
- Once the cupcakes are cool generously swirl with allergy-friendly frosting and top with safe chocolate chips sprinkles or festive decorations as desired

I always look forward to swirling heaps of frosting on top and seeing my little ones design their own spooky faces with allergy-friendly decorations it turns dessert time into craft time
Storage Tips
Once decorated store cupcakes in a single layer inside an airtight container at room temperature for up to two days For longer keeping refrigerate for up to five days Let them come to room temperature before serving for the best frosting texture You can also bake the cupcakes ahead of time and freeze them plain then thaw overnight and decorate fresh
Ingredient Substitutions
If you don’t have oat milk any other unsweetened plant milk like rice or hemp milk works nicely Just ensure it is allergy-safe for your needs For the oil a light neutral variety is best avoid olive oil which could overpower the chocolate Applesauce can work as a partial swap for oil if you want to lighten them up but the crumb will be a bit chewier
Serving Suggestions
Arrange the cupcakes on a platter with mini pumpkins or spider web doilies for a Halloween centerpiece Top with orange and purple sprinkles for instant pizzazz or use edible eyes for a playful monster effect Serve with cold oat milk or warm cider for a festive treat
