The almond flour is non-negotiable here—it's what keeps this crust light yet sturdy. Bob's Red Mill or Anthony's Goods are my go-tos, but any fine almond flour works. Skip the pre-sweetened kind; you want full control over sweetness. For the apples, Granny Smiths are ideal—their tartness balances the natural sweetness, but Honeycrisp or Fuji work too. Just make sure they're firm and free of bruises. The apple fiber powder is the secret to that thick, jammy filling without added sugar—NOW Foods sells it online if you can't find it locally.
No almond flour? Oat flour or coconut flour can work in a pinch, but texture will differ—oat flour makes it denser, coconut flour requires extra liquid. Running low on apple fiber? Unsweetened applesauce at half the amount gets you close, though it won't thicken quite the same. The erythritol can be swapped for monk fruit sweetener or stevia blend, but taste-test first—some brands have aftertastes. For the crust, if you can't find cold butter, chill it for 30 minutes—it's crucial for that flaky texture. And that honey glaze? Maple syrup or agave work just as well if you're avoiding honey.
The crust keeps best in the fridge for 3 days wrapped tightly in parchment, or 2 months frozen between layers of parchment. Assemble the pie right before baking—this isn't a make-ahead filling. The apples caramelize quickly, so don't overcook. Once baked, let it cool completely before slicing—at least 2 hours. Store leftovers in the fridge for 4 days or freeze for 3 months. I always make a double batch—one for dinner, one for breakfast the next day. Trust me, warm pie with coffee is a game-changer.

Step-by-step instructions for skinny apple pie
Here's how to create a lighter, flakier crust that still delivers all the cozy pie vibes.
Make the Almond Flour Crust
In a food processor, pulse the 2 cups almond flour and 0.5 cup granulated erythritol together until combined but not fully ground. Add the 0.5 cup cold unsalted butter (cut into small cubes) and pulse until the mixture resembles coarse crumbs with pea-sized butter pieces remaining. This texture is crucial for creating flaky layers.
Transfer the mixture to a bowl and stir in the 1 whole large egg and 1 tsp vanilla extract until fully incorporated. The dough should hold together when pressed but not be sticky. If it's too dry, add 1 teaspoon of cold water; if too wet, chill for 10 minutes before proceeding. Divide the dough into two equal portions and flatten each into a 7-inch round on parchment paper.
Prepare the Spiced Apple Filling
Peel, core, and thinly slice the 4 medium Granny Smith apples (about ¼-inch thick). In a large bowl, combine the sliced apples with 0.25 cup apple fiber powder, 2 tbsp ground cinnamon, 0.5 tsp ground nutmeg, 1 tbsp lemon juice, and 0.5 tsp sea salt. Toss gently to coat evenly. The fiber powder helps thicken the filling naturally without added sugar.
Let the apple mixture sit for 10 minutes while you preheat the oven to 375°F. This resting time allows the apples to release some moisture and soften slightly, ensuring a juicy but not soggy filling. If using monk fruit sweetener, add 1 teaspoon now for extra sweetness.
Assemble and Bake the Pie
Place one flattened almond flour crust in a 9-inch pie dish and press it gently into the bottom and up the sides. Pour the apple filling into the crust, mounding it slightly in the center. Brush the edges of the crust with 1 tbsp light coconut oil to help seal it when you add the top crust.
Roll out the second crust and place it over the filling. Crimp the edges together using your fingers or a fork, then cut 4 small slits in the center to allow steam to escape. Bake for 35-40 minutes until the crust is golden brown and the filling bubbles around the edges. The center should still have a slight jiggle when gently shaken.
Finish with Honey Glaze
Remove the pie from the oven and let it cool for 10 minutes. In a small bowl, whisk together 1 tbsp raw honey with 1 teaspoon of warm water until smooth. Brush the glaze evenly over the top crust while it's still warm. This step adds a subtle sweetness and shine without overpowering the natural apple flavor.
Allow the pie to cool completely before slicing. The filling will firm up as it cools, making it easier to serve. Store leftovers in the refrigerator for up to 3 days or freeze for 2 months. The almond flour crust stays crisp even when reheated—just warm slices in the oven at 350°F for 5 minutes to refresh.
Pro Tips For Making Skinny Apple Pie
- CHILL THE BUTTER FIRST: I learned this the hard way—using butter straight from the fridge makes the crust tough. Cut that cold butter into tiny, pea-sized pieces (yes, even if it’s rock-hard) and pulse it with the almond flour in short bursts. The goal? Tiny, even crumbs that melt into flaky layers instead of clumping into a brick.
- WEIGH THE ERYTHRITOL: Spooning granulated erythritol by volume leads to a dry, crumbly crust. Use a kitchen scale—you’ll need about 100g for a standard crust. Pack it lightly into the measuring cup if scooping, but don’t tamp it down. Too much and your pie turns into almond-flour crackers.
- PRESS THE CRUST HARD: This isn’t the prettiest method, but it’s the tastiest. After rolling out the dough, press it into the pie dish with your fingers—especially the edges—until it’s an even ¼-inch thick. Skip this, and the crust will puff up unevenly or shrink while baking. (Your future self will thank you.)
- BAKE LOW AND SLOW: Sounds weird, but it works: 325°F for 40-45 minutes, not the 375°F you’d use for regular pie. Almond flour burns faster than flour, and rushing it turns the crust into a sad, gray mess. A toothpick should come out clean, but the edges should still look pale—golden happens in the cooling.
Troubleshooting great skinny apple pie
Crust Too Dry
If your almond flour crust feels too dry and crumbly, don’t panic—this is common with nut-based flours. The fix is simple: add 1 teaspoon of cold water at a time to the dough until it just holds together when pressed.
Mix gently with a fork to avoid overworking it. If the dough still feels too dry after adding water, chill it for 10 minutes before rolling—this helps the moisture distribute evenly. 💧
Filling Too Watery
An overly juicy filling can make your crust soggy, but you can salvage it. Before baking, sprinkle 1 tablespoon of almond flour directly over the filling to absorb excess moisture.
Alternatively, pre-cook the apples for 5 minutes in a skillet with 1 teaspoon of coconut oil to draw out some liquid before assembling. This step is especially helpful if your apples are particularly juicy. 🍏
Crust Not Flaky
A non-flaky crust usually means the butter wasn’t cold enough or was overworked. For next time, ensure your butter is frozen solid before cutting into cubes, and pulse it in the food processor just until pea-sized pieces remain—no longer.
If you’ve already mixed the dough, don’t worry: roll it out as thinly as possible and bake at 375°F for 5 minutes before adding the filling. This pre-baking step creates a barrier that prevents sogginess. ✨
Apples Burning
If the top of your pie is browning too quickly while the filling is still undercooked, cover the crust with a circle of aluminum foil during baking. Remove the foil for the last 10 minutes to let it crisp up.
Alternatively, brush the exposed crust with 1 tablespoon of light coconut oil midway through baking to slow browning. This trick works wonders for even cooking. 🔥
Glaze Not Setting
A runny glaze happens when the pie cools too quickly. Let the pie cool for at least 15 minutes before applying the honey glaze—this gives the crust time to firm up slightly. For extra hold, mix ½ teaspoon of cornstarch into your glaze before brushing.
If you’ve already applied it and it’s still sticky, broil the pie for 1-2 minutes on low heat to set the sugar. 🍯
Pie Sinking Mid-Bake
Sinking crusts often result from insufficient crimping or filling that’s too heavy. Next time, press the edges of the top and bottom crusts together firmly using your fingers or a fork.
For extra support, place a pie weight or dried beans on the top crust during the first 20 minutes of baking. This keeps the filling from pushing the crust down while it sets. 🏋️♀️

Frequently asked questions
Can I make this skinny apple pie without almond flour?
Yes! For a lighter crust, try oat flour or coconut flour—though textures will differ slightly. Oat flour makes it denser, while coconut flour requires 1 extra tablespoon of water per ¼ cup flour. Whole wheat flour works too but may be less flaky. The key is adjusting moisture levels to prevent dryness.
How do I prevent the crust from getting soggy?
Prevent sogginess by pre-baking the bottom crust for 5 minutes at 375°F before adding filling. Brush edges with coconut oil to seal, and sprinkle 1 tbsp almond flour over the filling to absorb moisture. For extra insurance, chill the pie 20 minutes before baking.
Can I use regular sugar instead of erythritol?
You can substitute ¼ cup regular sugar for the erythritol, but expect a sweeter, denser crust. Reduce to 2 tbsp if you prefer less sweetness. For a middle ground, mix 2 tbsp erythritol + 2 tbsp sugar. The crust will be slightly heavier but still delicious.
What's the best way to reheat slices?
Reheat individual slices at 350°F for 5 minutes to maintain crispness. For a crispy crust, place slices on a baking sheet lined with parchment. Avoid microwaving—it makes the crust rubbery.
How can I make this pie lower in carbs?
For fewer carbs, replace the honey glaze with 1 tsp cinnamon sugar blend (cinnamon + erythritol). Use 1 extra cup sliced apples (they're low-carb) and skip the lemon juice if you're tracking carbs closely. This keeps carbs under 20g per slice.
