Dairy-Free Gluten-Free Boston Cream Pie
A classic Boston cream pie reimagined without gluten, featuring a light potato starch sponge cake split and filled with rich vanilla custard, then topped with a glossy chocolate glaze. The potato starch creates an unexpectedly tender crumb while almond milk keeps the custard smooth and dairy-free. Perfect for special occasions when you need an elegant dessert that accommodates gluten sensitivities. The key to success lies in properly whipping the egg whites and working quickly with the chocolate glaze to achieve that signature mirror-like finish.

Cake layers and custard can be made 1 day ahead. Assemble and glaze day of serving for best appearance.
Serve chilled. Cut with sharp knife wiped clean between slices for neat presentation.

FAQ
Can I make this dairy-free?
Yes, this recipe already uses almond milk and non-dairy whipping cream. Ensure your chocolate is also dairy-free for completely dairy-free dessert.
What if I don't have potato starch?
Rice flour works as 1:1 substitute, or try cornstarch at 3/4 ratio. Avoid regular flour as this defeats gluten-free purpose.
How long will this keep refrigerated?
Best eaten within 3 days when stored covered. Glaze stays glossy for about 24 hours before dulling slightly.
