Whisk the sugar with the beaten eggs until slightly foamy.
Add milk, baking mix, vanilla, salt, nutmeg, and melted butter. Blend until smooth.
Pour the batter into the pie plate. Tap gently to release bubbles.
Bake 45–50 minutes until golden and center barely jiggles. Cool before slicing.
Notes
For a richer custard, swap in half-and-half for 1/2 cup of the milk. Dust the top with cinnamon sugar after baking, or add a handful of toasted coconut for a tropical twist. Chill leftovers tightly covered for up to 3 days; the texture firms beautifully.This recipe is an original creation inspired by classic Magic Crust Custard Pie Recipe flavors.
