When you crave a rich, comforting custard dessert but want to skip the hassle of rolling out pastry dough, crustless pies are the ultimate kitchen solution. Traditional southern custard pies often rely on heavy pie crusts and cups of refined white sugar, which can feel heavy and cause unwanted blood sugar spikes. This Sugar-Free Crustless Coconut Pie delivers all the warm, tropical comfort of a classic bakery treat with none of the excess sugar or prep work.
By combining eggs, milk, flour, and shredded coconut into a simple batter, the pie magically separates as it bakes in the oven—forming a delicate, golden crust on top while leaving a velvety, creamy custard center below. Best of all, it requires no mixer, no blind baking, and no fuss, making it a foolproof dessert for busy weeknights, family dinners, or holiday gatherings.

Simple Ingredients for a Self-Crusting Custard
This recipe uses everyday pantry staples and healthy sugar alternatives to build a rich, flavorful dessert with minimal effort.
Pie Base & Custard Ingredients
- 4 large eggs (room temperature): Acts as the primary binder and creates the rich custard structure.
- 2/3 cup granulated sugar-free sweetener (allulose or monk fruit): Sweetens the custard cleanly without any artificial aftertaste.
- 1/2 cup all-purpose flour: Provides structure for the self-forming crust (can substitute an almond flour or coconut flour blend for lower carbs).
- 1/2 teaspoon salt: Enhances and balances the sweet coconut flavor profile.
- 2 cups whole milk: Creates a rich, creamy liquid base for the custard (unsweetened almond milk can also be used).
- 1 teaspoon pure vanilla extract: Adds aromatic depth and bakery-style warmth.
- 1/2 cup unsalted butter (melted and slightly cooled): Adds richness and helps form the golden top layer.
- 1 cup shredded coconut (unsweetened): Provides a wonderful chewy texture and deep coconut taste throughout the pie.
Step-by-Step Instructions
Follow these three simple steps to mix, bake, and serve your crustless pie.
Step 1: Prepare the Batter
- Preheat your oven to 350°F (175°C) and lightly grease a 9-inch pie dish with butter or cooking spray.
- In a large mixing bowl, beat the 4 room-temperature eggs and 2/3 cup of granulated sugar-free sweetener together until pale, light, and slightly frothy (about 2 minutes).
- Sprinkle in the 1/2 cup of flour and 1/2 teaspoon of salt. Whisk gently until smooth and fully incorporated into the egg mixture.
Step 2: Add Wet Ingredients and Coconut
- Pour in the 2 cups of whole milk and 1 teaspoon of pure vanilla extract, whisking gently to combine.
- Slowly drizzle in the 1/2 cup of melted, slightly cooled butter while stirring constantly until the liquid is smooth.
- Fold in the 1 cup of unsweetened shredded coconut gently with a rubber spatula until the flakes are evenly distributed throughout the batter.
Step 3: Bake and Rest
- Pour the prepared batter directly into your greased 9-inch pie dish.
- Bake in the preheated oven for 40 to 45 minutes, or until the edges are golden brown, the top is set, and the center jiggles just slightly when gently shaken.
- Remove the pie from the oven and let it rest at room temperature for at least 20 to 30 minutes to allow the custard to firm up before slicing. Serve warm or chilled!
Pro Tips for Bakery-Style Results
- Use Room-Temperature Dairy and Eggs: Bringing your eggs and milk to room temperature ensures that the warm melted butter incorporates smoothly without clumping into little pieces.
- Toast the Coconut for Extra Flavor: For an enhanced nutty taste, lightly toast your shredded coconut in a dry skillet over medium-low heat for 3–4 minutes before folding it into the batter.
- Allow Adequate Rest Time: Do not cut the pie immediately while it is piping hot from the oven. Letting it rest allows the custard to set properly for clean, neat slices.
- Adjust Flours to Fit Your Goals: While standard all-purpose flour creates a classic texture, you can swap it for a low-carb almond flour blend if you prefer a lower carbohydrate count.
Serving and Storage Instructions
- Serving Suggestions: Enjoy a slice on its own, or top it with a dollop of sugar-free whipped cream and a light dusting of cinnamon.
- Refrigeration: Cover leftover pie securely with plastic wrap or store it in an airtight container in the refrigerator for up to 3 to 4 days. It tastes exceptionally refreshing when served chilled!
FAQs
How does a crustless pie form its own crust?
As the pie bakes, the combination of flour, eggs, and butter naturally separates and rises during the baking process. The flour and butter migrate toward the top to form a light, golden crust layer, while the eggs and milk set into a dense, creamy custard beneath.
Can I use almond flour instead of all-purpose flour?
Yes, you can substitute a low-carb alternative like almond flour or a specialty low-carb baking blend. Keep in mind that grain-free flours absorb moisture differently, so the resulting texture may be slightly denser, but it will still taste delicious!
Why is my custard center still liquid?
If the center remains too runny after 45 minutes, it usually means the oven temperature was slightly low or the pie needs an extra 5 to 8 minutes of baking time. Ensure the edges are golden and the center is set with only a very slight jiggle before taking it out.
Can I make this pie ahead of time?
Yes! This pie is a fantastic make-ahead dessert. You can bake it the night before, let it cool completely, and keep it stored in the refrigerator until you are ready to slice and serve.

3-Step Easy Sugar-Free Crustless Coconut Pie
- Total Time: 60 minutes active preparation and baking, plus 20–30 minutes resting time.
- Yield: 8 slices from one 9-inch pie 1x
Description
Enjoy the rich, tropical flavor of coconut custard pie without the hassle of making a pastry crust or adding refined sugar. This easy sugar-free crustless coconut pie combines eggs, milk, butter, vanilla, and unsweetened shredded coconut to create a creamy, comforting dessert with a beautifully golden top. Sweetened with allulose or a suitable granulated monk fruit sweetener, it is simple to prepare in one bowl and perfect for family dinners, holidays, or an everyday low-sugar treat. Serve it warm or chilled for a delicious, fuss-free dessert.
Ingredients
- 4 large eggs, at room temperature
- 2/3 cup granulated sugar-free sweetener, such as allulose or a baking-suitable monk fruit blend
- 1/2 cup all-purpose flour
- 1/2 teaspoon salt
- 2 cups whole milk, preferably at room temperature
- 1 teaspoon pure vanilla extract
- 1/2 cup unsalted butter, melted and slightly cooled
- 1 cup unsweetened shredded coconut
- Butter or cooking spray, for greasing the pie dish
Instructions
Prepare the Batter: Preheat the oven to 350°F (175°C). Lightly grease a 9-inch pie dish. In a large mixing bowl, beat the eggs and sugar-free sweetener until pale and slightly frothy. Whisk in the flour and salt until smooth.
2. Add the Milk and Coconut: Gradually whisk in the milk and vanilla extract. Slowly stir in the melted, slightly cooled butter until combined. Gently fold in the unsweetened shredded coconut, distributing it evenly throughout the batter.
3. Bake and Cool: Pour the batter into the prepared pie dish. Bake for 40–45 minutes, or until the top is golden, the edges are set, and the center has only a slight jiggle. Remove from the oven and allow the pie to cool for 20–30 minutes before slicing. Serve warm or refrigerate for a chilled custard-style dessert.
Notes
- Sweetener choice: Allulose generally provides a texture and sweetness closer to regular sugar. Monk fruit blends vary in sweetness, so check the manufacturer’s conversion instructions.
- Room-temperature ingredients: Let the eggs and milk come to room temperature before mixing to help the melted butter incorporate smoothly.
- Extra coconut flavor: Lightly toast the shredded coconut in a dry skillet over medium-low heat for 3–4 minutes before adding it to the batter.
- Flour substitutions: Almond flour or coconut flour may change the pie’s texture and how it sets. Coconut flour is especially absorbent, so it should not be substituted cup-for-cup without adjusting the recipe.
- Serving suggestion: Serve with sugar-free whipped cream, a pinch of cinnamon, or a few toasted coconut flakes.
- Storage: Refrigerate covered leftovers for 3–4 days. For food safety, refrigerate the pie within two hours of baking.
- Make-ahead tip: Bake the pie a day ahead, cool it completely, and refrigerate until ready to serve.
- Baking tip: The pie should be set around the edges with a slight jiggle in the center. If it remains noticeably liquid, bake for another 5 minutes and check again.
