This Crustless Rhubarb Custard Pie is a delicious way to showcase spring and early summer’s tangy rhubarb in a dessert that’s simple, nostalgic, and comforting. No need to fuss with a pie crust — this recipe makes its own soft, custard-like base while baking. It’s light, subtly sweet, and lets the bright, tart rhubarb shine.

Perfect for brunch, afternoon tea, or a light dessert, this custard pie is an old-fashioned favorite with a modern twist — all the goodness of a classic pie with half the effort!

Ingredients

Dry Ingredients

• 3/4 cup granulated sugar

• 1/2 cup all-purpose flour

• 1/2 teaspoon baking powder

• 1/4 teaspoon salt

Wet Ingredients

• 3 large eggs

• 1 1/2 cups whole milk (or half-and-half for a richer custard)

• 1 teaspoon vanilla extract

• 2 tablespoons unsalted butter, melted and slightly cooled

Filling

• 2 to 2 1/2 cups fresh rhubarb, diced (about 3–4 medium stalks)

• Optional: 1/4 teaspoon ground cinnamon or nutmeg for extra warmth

Toppings (Optional)

• Powdered sugar for dusting

• Whipped cream

• Vanilla ice cream

Equipment

• Mixing bowls

• Whisk

• 9-inch pie dish (or round baking dish)

• Measuring cups and spoons

• Spatula

Instructions

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C). Lightly grease a 9-inch pie dish with butter or nonstick spray.

Step 2: Prepare the Rhubarb

Wash and dice the rhubarb into ½-inch pieces. If the stalks are especially thick or stringy, peel the outer layer. Set aside.

Tip: Fresh rhubarb works best, but if using frozen, be sure to thaw and drain thoroughly to avoid excess moisture in the custard.

Step 3: Mix the Dry Ingredients

In a medium bowl, whisk together the sugar, flour, baking powder, and salt. This helps distribute the flour evenly so there are no clumps later.

Step 4: Add Wet Ingredients

In a large bowl, beat the eggs. Then add the milk, vanilla extract, and melted butter. Whisk until combined.

Gradually add the dry mixture to the wet ingredients and stir until a smooth batter forms. It will be thin — that’s normal for a custard pie.

Step 5: Assemble the Pie

Spread the chopped rhubarb evenly across the bottom of the prepared pie dish. If you’re using cinnamon or nutmeg, sprinkle it over the rhubarb now.

Slowly pour the custard batter over the rhubarb. Use a spatula to gently distribute the rhubarb if it clumps.

Don’t stir once the custard is poured — the rhubarb should stay at the bottom to create a fruit layer under the soft custard top.

Step 6: Bake

Bake for 45 to 50 minutes, or until the custard is set and the top is lightly golden. The center should be firm but slightly jiggly — it will continue to set as it cools.

Check at the 40-minute mark and tent with foil if the top is browning too quickly.

Step 7: Cool and Serve

Allow the pie to cool at room temperature for at least 30 minutes. For best texture, refrigerate for another 1–2 hours before slicing.

Serve chilled or at room temperature. Dust with powdered sugar or top with whipped cream or ice cream if desired.

Serving Suggestions

This pie is lovely on its own but pairs well with:

• A dollop of fresh whipped cream

• A scoop of vanilla bean ice cream

• A drizzle of light honey or maple syrup for extra sweetness

• Fresh berries like strawberries or raspberries on the side

It also makes a beautiful addition to a spring brunch table or Easter dessert spread.
