Old-Fashioned Molasses Pie with Crumb Topping (Wet Bottom Style)

Wet Bottom Pie: What It Means and What to Expect

This is a wet-bottom pie, which means the filling layer stays soft, gooey, and slightly syrupy after baking even when fully cooled. That’s not a mistake. That’s the whole texture.

When you slice this pie, the bottom layer will be glossy and sticky. A little syrup may pool on the plate. The crumb topping will be set and golden above it, and together the contrast is exactly what makes this pie memorable.

To get the best set on the filling:

• Let the pie cool completely before slicing (at least 1-2 hours)
• Refrigerating the pie for 30 minutes before slicing makes it easier to cut clean pieces
• Don’t overbake trying to get the center to firm up. It won’t set, and you’ll risk burning the crumb topping

A dry-bottom pie has more of a cake-like texture rather than a gooey filling.

Start with the pie crust.

I used whole wheat pie crust as a base for this crumb pie, but my grandma’s pie crust recipe would be fabulous as well. Whichever you choose, you’ll only need to make a ½ recipe since this pie calls for just a bottom crust.

How to Make our Molasses Pie Recipe

This pie has two parts: the gooey bottom and the crumb pie topping.

Make the molasses filling. Cook brown sugar, molasses, egg, water, flour and vanilla on the stove over medium heat, whisking often, until the mixture has thickened slightly, about 5-10 minutes, stirring often. I let mine come to a very low boil, but I didn’t let it boil for long. Pour the molasses mixture into your prepared (but unbaked) pie shell.

Make the crumb topping. It’s just flour, brown sugar, melted butter and baking soda that you’ll mix together. Sprinkle these crumbs over the molasses mixture and bake the pie at 375 for 40-45 minutes.

Let the pie cool. Because this pie has a gooey filling, you’ll want to let it cool before you slice it. This will allow the filling to set and firm up. Even then, this crumb pie is considered a “wet-bottom” pie. It’s gooey and may have a little syrup dripping out as you slice your piece of pie. It’s a similar technique to our funny cake pie.

How to Serve Molasses Crumb Pie

This pie was traditionally served at breakfast in Pennsylvania Mennonite households, kind of like a coffee cake. That said, it works just as well as a dessert.

For serving:

• A large dollop of whipped cream on top helps balance the deep molasses flavor. I highly recommended if you’re serving guests with varying molasses tolerance
• A scoop of vanilla ice cream turns this into a proper dessert
• A light sprinkle of cinnamon on the whipped cream makes it look as good as it tastes

For storage, cover the pie loosely and store at room temperature for up to 2 days, or refrigerate for up to 5 days. The crumb topping softens slightly in the fridge but the flavor deepens. Many prefer eating the molasses pie cold!

Can I make this pie ahead of time?

Yes. Bake the pie the day before and store it loosely covered at room temperature overnight. The filling sets further as it cools, making day-two slices actually cleaner than same-day slices. Add whipped cream right before serving.
