Recipe Ingredients
For the Crust
- 1 1/2 cups Almond Flour
- 3 tbsp Cocoa Powder
- 3 tbsp Powdered Erythritol
- 1/4 cup Butter, melted
- 1 Large Egg Yolk
- 1/4 tsp Salt
For the Ganache Filling
- 8 oz Sugar-Free Dark Chocolate, finely chopped
- 1 cup Heavy Cream
- 2 tbsp Butter
- 1 tsp Vanilla Extract
- Pinch of Salt
For the Topping
- Flaky Sea Salt
- Fresh Raspberries
How To Make
Step 1
Preheat your oven to 350°F. In a bowl, combine the almond flour, cocoa powder, powdered erythritol, and salt. Stir in the melted butter and egg yolk until a dough forms.
Step 2
Press the dough evenly into the bottom and up the sides of a 9-inch tart pan with a removable bottom. Use the back of a measuring cup to get it smooth and even.
Bake for 12 to 14 minutes until the crust feels firm and dry to the touch. Let it cool completely in the pan.
Step 3
Place the finely chopped sugar-free dark chocolate in a heatproof bowl. Heat the heavy cream in a small saucepan over medium heat until it just begins to simmer around the edges.
Step 4
Pour the hot cream over the chocolate and let it sit undisturbed for 2 minutes. Then stir slowly from the center outward in small circles until the ganache is completely smooth and glossy. Stir in the butter and vanilla extract until melted and incorporated.
Step 5
Pour the warm ganache into the cooled tart shell and gently tilt the pan to spread it evenly. Tap the pan on the counter a few times to smooth the surface and remove any air bubbles.
Step 6
Refrigerate the tart for at least 3 hours until the ganache is set and firm. It should be smooth and silky when you touch the surface.
Step 7
Before serving, remove the tart from the pan, sprinkle with flaky sea salt, and arrange fresh raspberries on top. Let it sit at room temperature for 10 minutes before slicing for the cleanest cuts.
Tips
Press the Crust Thin and Even
Almond flour crusts puff up less than regular crusts, so whatever thickness you press it to is pretty much what you get. If some spots are thicker than others, those areas will be soft and crumbly while the thin spots get too dark.
Use the flat bottom of a measuring cup to press it down firmly, then use the back of a spoon to push it up the sides. You want it about 1/4 inch thick everywhere.
Really pack it in tight. If you just loosely press it, it’ll fall apart the second you try to slice the tart later.
Let the Crust Cool Completely Before Filling
If you pour the ganache into a warm crust, the butter in the crust will start melting again and the whole base gets greasy and soft. It won’t hold together when you try to remove the tart from the pan.
Give it at least 30 minutes on the counter after baking. If you want to speed things up, pop it in the fridge for 15 minutes. The crust should feel completely cool to the touch before you add the ganache.
Chop the Chocolate Really Small
Sugar-free dark chocolate doesn’t melt as easily as regular chocolate. If your pieces are too big, the hot cream won’t fully melt them and you’ll end up with little chunks in your ganache.
Chop it into pieces no bigger than a pea. The smaller the better. This way the heat from the cream can melt everything evenly without you having to stir aggressively, which can introduce air bubbles.

Frequently Asked Questions
What brand of sugar-free dark chocolate works best for the ganache?
Look for brands like Lily’s, ChocZero, or Hu Kitchen that use sweeteners like stevia, monk fruit, or erythritol instead of sugar. Make sure the label says no added sugar and check the net carbs per serving to keep it keto friendly.
Avoid chocolate that uses maltitol as the sweetener because it can spike blood sugar almost as much as regular sugar and tends to cause digestive issues for a lot of people.
