Have you heard of a kabocha squash? It is a big green winter squash that looks like a dark green pumpkin. Kabocha squash is one of my favorites because of its natural sweetness. (Kabocha squash is even sweeter than butternut squash!)
I wanted to go outside the creative box a little today and create a winter squash dessert. My kids love fluffy, creamy mousse, so I attempted that with this sweet roasted squash.

Here is a photo of the baked squash. It almost caramelizes as it bakes, making it nice and sweet.
Recipe Step-By-Step Directions:

Step 1: Remove the roasted squash flesh from the rind with a knife and mash it in a bowl.
Step 2: Move the squash into a Blender or Vitamix. Add the coconut sugar, spices, 1 cup of the heavy cream, and the egg yolks. Puree them for 25-30 seconds until there are no lumps, and pour them into a small pot.
🔑 Sandi says: You can also put the roasted squash and ingredients into the pan and use an immersion blender to whip it all.
Step 3: Cook on medium-low heat. Whisk frequently to prevent sticking. Cook for 8-10 minutes until the mixture thickens. Remove from the stove and allow it to cool.

Step 4: Make the whipped cream. Pour the heavy cream into a bowl and whip it with an electric mixer until the cream forms stiff peaks.

Step 5: Pour the cooled squash mixture onto the whipped cream.

Step 6: Gently fold the two together and chill for at least 2 hours. Pipe or spoon it into glasses or small bowls. Serve with whipped cream.
For a fun variation, crush Gluten-Free Vanilla Wafers on the bottom of the glass. You may also want to make a batch of these fall-flavored Gluten Free Maple Walnut Blondies.

I have seen his squash all over the place lately, but have never tried it. I will have to now. What a fun mousse, and so funny you don't disclose to your kids. Mine are ok if I tell them after they like something.
