Food allergies and dietary restrictions often mean that social gatherings involving food require extra planning. If you have a child with special dietary needs, birthday parties can be particularly cumbersome because: cake.

Dairy, soy, gluten, eggs, food coloring… there are all sorts of delicious allergens in most cakes. So what do you do if your child can’t eat the provided cake at a gathering? You B.Y.O.C. (Bring Your Own Cake) for your child to enjoy alongside his or her cake-nibbling cohorts. The problem is this often means you’re left with an entire batch of allergen-friendly cupcakes or 9/10 of a whole cake at home. (The taste buds love it; the waistline does not.) The solution: Duncan Hines’ Perfect Size Cake.

For those with soy, egg, and dairy allergies, this mini cake is perfect for birthday party B.Y.O.C. At most, you’re left with a few extra slices. No biggy!

Just be sure to check the label to ensure you grabbed a variety that suits your dietary needs. Make it vegan by opting for the dry cake mix + soda trick (all you do is mix 1/2 a can of soda into the dry mix and bake as specified in the package instructions) and substitute the butter for coconut oil or non-dairy butter and you’re set! The cake even comes with its own tiny baking tin with easy cake extraction. Bonus: the icing tastes better than the standard plastic tub product. Just be sure to have an electric hand mixer available to whip it up.

Let them eat cake!
