Keto Pecan Pie Bars

Why These Keto Pecan Pie Bars Are the Best

1. Classic flavor, no sugar crash: These taste just like traditional pecan pie — buttery, ultra rich, and sweet — but without the refined sugar or carbs.
2. Simple ingredients: You only need a few basic low-carb staples to make both the crust and the filling.
3. Perfect texture: The gooey pecan filling pairs perfectly with the shortbread-style crust, making these bars taste indulgent yet balanced.

Ingredients Breakdown

See recipe card at the end of the post for full ingredient measurements and units.

Coconut Flour

Used for the crust — it provides structure while keeping the recipe gluten free and low carb. Coconut flour absorbs more liquid than other flours, so only a small amount is needed.

Sugar-Free Sweetener

Adds sweetness to both the crust and filling without adding carbs. For the crust, any sweetener can be used. For the filling, I highly recommend using granulated allulose for the best texture as it gives the filling that perfect gooey consistency.

Butter

Provides rich, buttery flavor in both the crust and filling.

Eggs

Bind both layers together and help set the filling as it bakes. Make sure the eggs for the filling are room temperature so they don’t cause the warm filling to seize up.

Heavy Cream

Makes the filling extra creamy and smooth. It balances the sweetness and helps create that signature gooey texture.

Pecans

Fresh pecan pieces bring crunch and that unmistakable toasty, nutty flavor that defines pecan pie.

Vanilla Extract

A touch of vanilla rounds out the caramel flavor and brings a warm, cozy aroma.

Salt

A small amount of salt enhances all the sweet flavors and gives that irresistible sweet n’ salty balance.

Sugar-Free Chocolate Chips

Totally optional, but I love the flavor and sweetness they add. The combination of chocolate and pecans takes these bars to another level. If you omit them, you may want to add slightly extra sweetener to the filling.

How to Make Keto Pecan Pie Bars

1. Preheat and Prepare

Preheat your oven to 350°F and line an 8×8-inch pan with parchment paper.

2. Make the Crust

In a bowl, combine coconut flour, sweetener, melted butter, and egg. Mix until a dough forms, then press evenly into the bottom of your pan. Bake for 7 minutes and let it cool while you prepare the filling.

3. Start the Filling Base

Melt the butter in a saucepan over medium-low heat. Add the sweetener and stir until dissolved.

4. Simmer with Cream and Salt

Add the heavy cream and salt. Bring to a gentle simmer for about 15 minutes, stirring occasionally, until the mixture turns golden and slightly thickened.

5. Add Eggs and Vanilla

Remove from heat and let cool slightly. Whisk in room temperature eggs and vanilla until smooth.

6. Assemble and Bake

Spread the pecan pieces evenly over the cooled crust. Pour the filling mixture over the pecans, then sprinkle chocolate chips evenly across the top if using. Bake for 29–33 minutes until the center is just set.

7. Cool and Slice

Let the bars cool completely, then refrigerate for at least 20 minutes before slicing. For firmer bars, chill longer.

Tips for Success

1. Use allulose for the best texture: It creates a smooth, gooey consistency and doesn’t crystallize in the fridge.
2. Cool the filling before adding eggs: This prevents the mixture from seizing.
3. Chill before slicing: The bars will firm up and cut cleanly once they cool, giving you perfect squares.

Keto Pecan Pie Bar Variations

1. Chocolate Drizzle: Melt a few tablespoons of sugar-free chocolate and drizzle over the cooled bars.
2. Maple Pecan: Add a few drops of sugar-free maple extract to the filling for a classic flavor twist.
3. Salted Caramel: Sprinkle flaky sea salt over the top after baking for a gourmet touch.
