🧅 Amish Onion Cake — A Savory Old-Fashioned Comfort Bake You’ll Love
If you’ve never tasted Amish Onion Cake, prepare to discover one of the most comforting savory bakes ever to come out of a farmhouse kitchen. Despite its name, this dish isn’t sweet like dessert cake. Instead, it’s a rich, buttery, savory onion bread layered with caramelized onions and a soft, tender crumb that makes it perfect for dinner tables, potlucks, and cozy family gatherings.
Amish Onion Cake combines simple pantry staples into something deeply satisfying. Sweet onions mellow as they bake, blending with butter, eggs, milk, and sour cream to create a tender, almost custard-like interior with a lightly crisp, golden crust on top. The result is somewhere between a savory cake, a thick flatbread, and a comforting onion pie.
This recipe is loved for its rustic simplicity and its ability to feed a crowd without complicated techniques or fancy ingredients. Whether served alongside soups, stews, grilled meats, or enjoyed warm with butter, it quickly becomes a household favorite.
Let’s walk through everything you need to know to make this traditional savory bake perfectly in your own kitchen.

Step 1: Prepare the Onions
Chop onions into roughly 1-inch pieces. They will shrink and soften while baking.
Set aside while preparing the batter.
Step 2: Prepare the Butter
Divide the cold butter into two portions.
One portion is incorporated into the dough mixture, while the other is melted and drizzled over the cake before baking to create a rich topping.

In a large mixing bowl, combine:
• Flour
• Cornstarch
• Baking powder

Mix thoroughly to distribute ingredients evenly.
Step 4: Incorporate Butter
Cut half of the cold butter into small cubes and work it into the flour mixture using a pastry cutter or fingertips until crumbly.
This step creates a tender, flaky structure.
Step 5: Combine Wet Ingredients
In another bowl, whisk together:
• Eggs
• Whole milk
• Sour cream
Blend until smooth.
Step 6: Form the Batter
Gradually combine wet and dry mixtures, stirring gently until a thick batter forms. Avoid overmixing to keep the cake tender.
Step 7: Add the Onions
Fold chopped onions into the batter, ensuring even distribution.
Step 8: Transfer to Baking Dish
Spread mixture evenly into a greased baking pan or casserole dish.
Step 9: Add Butter and Seeds
Melt remaining butter and drizzle over the top.
Sprinkle poppy seeds evenly across the surface.
Step 10: Bake
Bake in a preheated oven at 375°F (190°C) for 40–50 minutes, or until golden and cooked through.
Allow to cool slightly before slicing.
