How to Make Easiest Pie Ever! Impossible Rhubarb Custard Pie
Ingredients
- 2 cups rhubarb, chopped
- 1 cup granulated sugar
- 1/2 cup all-purpose flour (or gluten-free flour)
- 1/4 teaspoon salt
- 2 cups milk
- 3 large eggs
- 1 teaspoon vanilla extract
- 1/4 teaspoon ground nutmeg

Directions
- Preheat your oven to 350°F (175°C). Make sure the oven is fully preheated to ensure even baking.
- In a large mixing bowl, combine the rhubarb, sugar, flour, and salt. Stir until the rhubarb is evenly coated. This step ensures that the fruit releases its juices, melding beautifully with the custard.
- In another bowl, whisk together the milk, eggs, vanilla extract, and nutmeg until well combined. Be sure to mix until you achieve a smooth, uniform texture.
- Pour the milk mixture into the rhubarb mixture and gently stir to combine. This is where the magic happens—watch as the ingredients meld together into a batter-like consistency.
- Pour the mixture into a greased pie dish. Use a light touch when pouring to prevent splashing.
- Bake for about 45-50 minutes, or until the custard is set and the top is lightly golden. You’ll know it’s done when it’s firm to the touch and pulls slightly away from the edges of the dish. The pie should also look perfectly puffy.
- Allow to cool before serving. Once it’s out of the oven, give it time to set up properly for the best texture.
How to Serve Easiest Pie Ever! Impossible Rhubarb Custard Pie
Serve this pie warm for a cozy treat or let it cool to room temperature for a refreshing dessert. Cut into generous slices and serve on a colorful plate to make your dessert table pop. A dollop of freshly whipped cream or a scoop of vanilla ice cream takes this dessert to the next level. For an added touch, consider sprinkling powdered sugar on top for a beautiful finish. It’s ideal for family dinners, brunch gatherings, or simply enjoying at home with a hot cup of tea.
How to Store Easiest Pie Ever! Impossible Rhubarb Custard Pie
To keep your pie fresh, store any leftovers in an airtight container in the refrigerator for up to 3 days. If you want to enjoy it later, you can freeze the pie whole. Wrap it tightly in plastic wrap and then aluminum foil to prevent freezer burn, storing it for up to 3 months. When ready to eat, thaw it overnight in the refrigerator and reheat gently in the oven at 350°F (175°C) until warmed through, approximately 15 minutes. Always check for signs of spoilage, like off smells or mold, before consuming.
Tips to Make Easiest Pie Ever! Impossible Rhubarb Custard Pie
- Prep all ingredients ahead to save time during baking. Measure everything out before you start mixing.
- Use fresh rhubarb whenever possible for the best flavor. If fresh isn’t available, frozen works too—just thaw and drain before using.
- Avoid oversweetening by tasting the rhubarb before adding sugar. Each batch can vary in tartness.
- Grease your pan well to ensure that the pie releases smoothly without sticking.
- If using gluten-free flour, opt for a 1:1 substitution for best results, or use almond flour for a different flavor profile.
- The custard can be a little wobbly right out of the oven; that’s normal. Let it cool to firm up.
- Serve with fresh mint or berries for an added burst of flavor and a pop of color.
- For a little crunch, sprinkle some chopped nuts on top before serving.
- Experiment with spices like cinnamon or lemon zest to complement the rhubarb’s tartness.
- Turn leftovers into a breakfast treat by serving them warm with yogurt and granola.
Variations
1. Vegan Rhubarb Custard Pie
Replace the milk with almond or oat milk, and use flax eggs instead of chicken eggs (1 tablespoon of flaxseed meal mixed with 2.5 tablespoons of water per egg). This adaptation makes it completely plant-based without sacrificing taste!
2. Nutty Protein Pie
Mix in some chopped nuts, like pecans or almonds, for added texture and protein. This addition gives a delightful crunch to contrast with the creamy filling.
3. Lemon-Lavender Rhubarb Pie
Add a tablespoon of lemon juice and a teaspoon of dried lavender to the milk mixture. The combination elevates the flavor profile and gives a floral hint that pairs beautifully with rhubarb.
4. Sweet and Spicy Twist
Incorporate a dash of cayenne pepper or finely chopped candied ginger into the filling for a surprising kick. This version brings an unexpected warmth to the traditional flavor.
5. Maple Walnut Rhubarb Pie
Substitute granulated sugar with maple syrup and throw in some toasted walnuts for a luscious maple-infused treat.
