Filled with a simple sugar-free chocolate mascarpone mousse, these keto-friendly chocolate cookies are great fun to bake with kids too. Give them the mousse to make, they’ll have fun licking the bowl clean. I know I did!

Ingredients (makes 13 sandwich cookies)

Cookies:
Chocolate mascarpone mousse:

Instructions

  1. Preheat the oven to 140 °C/ 285 °F (fan assisted), 160 °C/ 320 °F (conventional). Mix the nut butter and coconut butter together in a mixing bowl. (Some store-bought products will have a layer of oil on top which you should not use in this recipe or it may affect the texture.) Add the Erythritol and salt. Stir.
    Note: Apart from store-bought nut butter, you can easily Almond & Cashew Butter, coconut butter or other options such as sunbutter at home. Keto Chocolate Mousse Sandwich Cookies
  2. Add the egg and mix well.

  3. Form into a ball. If the dough is too runny (too much oil in the nut butter), add up to 4 tablespoons of ground almonds to thicken. Place in the fridge for 20 minutes to firm up.
  4. Roll the dough between 2 sheets of baking paper until about 1/2 cm (1/4 inch) thick.
    For a super quick no-rolling way: Simply create 26 balls (about 15 g/ 1/2 oz each) and then flatten using the bottom of a glass jar or your hand. They won't be perfectly symmetrical but still pretty! Keto Chocolate Mousse Sandwich Cookies
  5. Cut out your cookies using a 5 cm (2 inch) diameter cutter and careful place using a spatula onto a greaseproof lined baking tray.
  6. Roll the remaining dough back into a ball and repeat the rolling between 2 sheets of greaseproof and cutting step until all the dough is used up. You should get about 26 cookies in total.

  7. Bake in the oven for 30-35 minutes until golden. Carefully flip after about 20 minutes for even cooking. Remove from the oven and allow to cool on a wire rack.
  8. Meanwhile, add all the mousse ingredients to a mixing bowl and whisk with an electric whisk until smooth and thick. Don’t over whisk or the cream may curdle.

  9. Spread about 1 tablespoon of the filling onto one half of a cookie and top with another cookie to form a sandwich.

I found chocolate mascarpone cheese t the grocery store. I want to make you chocolate mascarpone filling cookie. How would I modify this recipe?

Reply

Hi Kim, as long as there is no added sugar in the mascarpone filling, you could just whip it with 1/2 cup cream plus the vanilla and sweetener (skip the cacao).

Would regular butter work in place of the nut butter?

Reply

I'm afraid it would not. Regular butter is 100% fat while almond butter is made with blended almonds. You could use any other nut butter, coconut butter (blended dried coconut meat), or seed butter such as sunflower seed butter. I hope this helps!

Hi Martina,
I haven't tried this recipe and couldn't figure out a way to just send you an email, so I decided to post on this blot item.
I wanted you to know that I have tried quite a few of your recipes recently - fathead dough, your bread, buns, stromboli, chicken braised in cream, etc., etc., and they have all turned out so WELL!!!!
The fathead dough is a game changer for sure and the stromboli a faavourite for my husband (who doesn't do keto, but eats what I cook, so he is kind of there).
Anyway, thank you for all you do, for your precision and careful testing!  Your recipes work for me and they have expanded my keto portfolio away from basic meat/veggies that we were doing.
Thank you thank you thank you!!

Thank you so much Linda, I really appreciate your kind words! I'm so happy to hear that!
