Low Carb Pecan Pie Bars

Pecan pie is one of those desserts that most people think they have to give up on a keto diet. Too much sugar, too many carbs. But that’s exactly why I made these low carb pecan pie bars.

They have a buttery almond flour crust on the bottom and a sticky, sweet caramel pecan topping that tastes like the real thing. The sweetener does all the heavy lifting here, so you get that classic flavor without the sugar spike.

What I really like about this recipe is how simple it is. The crust comes together in minutes, and the filling is just a quick stovetop caramel poured over toasted pecans. Nothing complicated at all.

These bars are low carb and keto friendly, which makes them perfect if you want a dessert that fits your way of eating without feeling like you’re missing out.

Once they set in the fridge, they slice up beautifully. They’re great for sharing or for keeping in the fridge all week when you need a little treat.

Ingredients

For the Crust

• 1 1/2 cups Almond Flour
• 2 tbsp Granulated Erythritol
• 3 tbsp Butter, melted
• 1/4 tsp Sea Salt

For the Filling

• 1 1/2 cups Pecan Halves
• 1/4 cup Butter
• 1/3 cup Brown Sugar Erythritol
• 1/4 cup Heavy Cream
• 1 tsp Vanilla Extract
• 1/4 tsp Sea Salt

How to Make

Step 1

Preheat your oven to 350 F. Line an 8×8 inch baking dish with parchment paper.

Step 2

Mix together the almond flour, erythritol, melted butter, and sea salt. Press firmly and evenly into the bottom of the prepared dish. Bake for 12 minutes until lightly golden.

Step 3

While the crust bakes, arrange the pecan halves in a single layer on a separate baking sheet and toast them in the oven for 5 minutes until fragrant.

Step 4

In a small saucepan over medium heat, melt the butter. Stir in the brown sugar erythritol, heavy cream, vanilla extract, and sea salt. Simmer for 3 to 4 minutes, stirring constantly, until the caramel thickens slightly.

Step 5

Arrange the toasted pecans over the baked crust. Pour the warm caramel evenly over the pecans.

Step 6

Bake for 12 to 15 minutes until the filling is bubbling. Let cool completely, then refrigerate for 2 hours before slicing into bars.

Helpful Tips

Press the Crust Firmly

When you press the almond flour mixture into the baking dish, really push it down hard using the flat bottom of a measuring cup or glass. You want it packed tight with no loose or crumbly spots.

Almond flour crusts don’t have gluten to hold them together like regular crusts do, so if you skip this step the crust will crumble apart when you try to slice the bars later. Take an extra minute here and make sure every corner and edge is evenly compressed.

Toast the Pecans Separately

Don’t skip toasting the pecans on a separate baking sheet. Five minutes in the oven brings out a deep, nutty flavor that you just won’t get from raw pecans. You’ll know they’re ready when you can smell them from across the kitchen.

Keep a close eye on them because they go from perfectly toasted to burnt really fast. Set a timer and check them at the 4 minute mark. Pull them out when they’re fragrant and slightly darker in color.

Spread them in a single layer so they toast evenly. If they’re piled on top of each other, the ones in the middle will stay raw while the edges burn.

Stir the Caramel the Entire Time

When you’re making the caramel filling on the stove, do not walk away or stop stirring. Erythritol-based caramel can go from smooth to grainy or scorched in seconds if you leave it sitting on the heat without attention.

Keep the heat at medium, not high. You want a gentle simmer with small bubbles, not a rolling boil. If it starts bubbling aggressively, lower the heat right away.

After 3 to 4 minutes it should coat the back of a spoon and look slightly thickened. That’s exactly when you want to pull it off the heat and pour it over the pecans.

Frequently Asked Questions

Can I use a different sugar-free sweetener instead of erythritol?

Yes, you can use monk fruit sweetener or allulose as a substitute. Monk fruit blends that measure like sugar work as a 1:1 swap, so the amounts stay the same.

Allulose is another good option and actually gives the caramel filling an even smoother texture since it doesn’t crystallize the way erythritol sometimes can. Just keep in mind that allulose is only about 70% as sweet as sugar, so you may want to add a little extra to taste.
