Hazelnut Coffee Mousse Tartlets – Low Carb and Gluten-Free


Hazelnut Coffee Mousse TartletsToday I am sharing a recipe from Beverly, a semi-retired pastry chef who has gone gluten and dairy free. She reached out to me a few months ago, telling me that she is a faithful reader and recommends my blog to gluten-free friends, low carb friends and even some pastry chefs!  She was putting together the desserts for a friend’s 50th birthday party and was making my Chocolate Peanut Butter Mousse Tarts in mini size, as well as putting her own spin on a variation so that she could offer two different flavours at the party.  Her variation sounded so good, I asked her to take pictures and send me the recipe so I could share it with all of you.

Enjoy these beautiful low carb Hazelnut Coffee Mousse Tartlets, courtesy of Beverly!  And if you have a great low carb, gluten-free recipe you want me to share here on All Day I Dream About Food, be sure to let me know.  But you have to send photos!

Hazelnut Coffee Mousse Tartlets – Low Carb and Gluten-Free

Yield: Makes 16 small or 32 mini tartlets! ( These things are very rich!).


    Hazelnut Butter:
  • 1-1/3 c. hazelnuts, roasted and skinned (or buy prepared at Trader Joe’s)
  • 2-3 TBSP. coconut oil, warmed to melt
  • 1½ to 2 TBSP. Nature’s Hollow sugar free maple syrup (Amazon)
  • 1/3 tsp. sea salt
  • Crust:
  • ¼ cup butter
  • ¼ cup cocoa powder
  • 3 TBSP. granulated erythritol (or sugar)
  • 1 large Safest Choice Egg, lightly beaten
  • 1 cup almond flour
  • ¾ cup unsweetened, shredded coconut
  • ½ cup chopped walnuts (or hazelnuts)
  • ½ tsp. vanilla extract
  • Filling:
  • 4 oz cream cheese, softened
  • ½ cup homemade hazelnut butter
  • ½ cup whipping cream
  • ¼ cup powdered erythritol (or powdered sugar)
  • 12- 20 drops liquid Stevia (English Toffee is very good)
  • 1 tsp vanilla extract
  • ½ sleeve Starbuck’s Via instant coffee (pure, no sugar variety)
  • Chocolate Glaze:
  • 5 TBSP. butter
  • 2 oz unsweetened chocolate, chopped
  • 2 TBSP. powdered erythritol (or ¼ cup powdered sugar)
  • ¼ cup cocoa powder
  • ¼ tsp. vanilla extract
  • 20 drops stevia extract (omit if using sugar)


  1. For the Hazelnut Butter: Process the hazelnuts in the food processor or Vitamix by pulsing. When finely ground but short of peanut butter consistency, add the oil, maple syrup, and sea salt. Continue to process by pulsing until mixture becomes nut butter. If too stiff you may add additional coconut oil or maple syrup for proper consistency. Store, covered, in small 1 cup container until needed.
  2. For the crust, melt butter in a medium saucepan over low heat. Stir in cocoa and erythritol (or sugar) and then slowly whisk in beaten egg. Cook, stirring constantly, until mixture thickens, about 1 minute. Remove from heat and stir in almond meal, coconut, nuts and vanilla. Press crust evenly into bottom and sides of 4 4-inch diameter tart pans with removable bottoms and refrigerate until firm (30-45 minutes).
  3. For the filling, beat cream cheese and hazelnut butter together until well combined. Beat in whipping cream, then beat in powdered erythritol (or sugar). Dissolve the Via coffee in the vanilla extract and add, continuing to blend until smooth and creamy.
  4. Line 16 small tartlet pans or 32 mini tartlet cups with paper liners. Line pans with Crust using 2 TBSP for the small tartlets and 1 TBSP for the mini tartlets.( Pressing the crust with a wooden tart tamper makes the task easier!)
  5. Place the Hazelnut Coffee Mousse Filling in a pastry bag fitted with a star tip and pipe into Tartlet crusts. Freeze while preparing the Chocolate Glaze.
  6. In a small saucepan over low, melt butter, unsweetened chocolate together and powdered erythritol (or sugar) together. Add cocoa powder and stir until smooth. Remove from heat and stir in vanilla and stevia extracts. While warm, not hot, drizzle decoratively over filling; decorate with a chocolate coffee bean or a hazelnut. Refrigerate tartlets until chocolate is set, about half an hour.
  7. These freeze beautifully.


Note: The proportions from the original recipe vary slightly . The addition of coffee required more sweetness. I also increased the cream to make the filling less rich.

*Note 2: If making 32 mini tartlets, make 1-1/2 times the Filling recipe to allow adequate mousse for piping.

Makes 16 small or 32 mini tartlets! ( These things are very rich!). For 16 servings, each serving has a total of 6.5 g of carbs and 2.7 g of fiber. Total NET CARBS = 3.8 g.

    These look delicious! I am a little confused though…why do you press the crust into 4 4″ pie pans and then in step 4 press them into 16 or 32 tart/mini tart pans? Is it to give you two alternatives? Thank you for clarifying.

      Hmmmm, since it’s not my recipe I will have to go back and look, but my original Peanut Butter Mousse tarts are made in four 4″ tart pans and Beverly was making hers much smaller. She may have not edited that properly.
