What is mascarpone cheese?

That is a good question! Have you ever had mascarpone cheese before? If you have I would guess it was in a tiramisu recipe or something Italian.

It’s a little more expensive than cream cheese, however, mascarpone cheese is practically the perfect ingredient for a keto diet.

There are several reasons for this. First, a serving of good mascarpone cheese has 0 carbs. Yes, ZERO. In fact, 8 ounces of mascarpone cheese has zero carbs. Count ’em.

On the other hand, cream cheese has 8 carbs in 8 ounces of cream cheese. Now, I do use both, however, depending on the flavor your’re looking for, mascarpone can be a fabulous low carb ingredient. In comparison, cream cheese is still not a lot of carbs, but zero is a lot better.

Second, I absolutely adore the flavor of a good mascarpone cheese. It’s almost like it’s a thick, decadent, heavy cream in a block or soft cheese form. Essentially, it’s an Italian cream cheese, but unlike American cream cheese, it’s made out of full fat cream. Mmmm.

Whereas mascarpone is made of full fat cream, American cream cheesemust contain at least 33% milkfat and not more than 55% moisture. It’s lower in fat than it’s Italian cousin, all of which gives it a more acidic flavor.

🔪 Instructions

How to make keto pumpkin mousse

This low carb dessert is so quick and easy to make you may not believe it at first. But truly, you can do it. It really is that simple to make.

First, place the cream in a medium-sized clean bowl and whip it up to stiff peaks. 

Second, take another bowl and in it use a hand mixer to blend together all other ingredients until smooth.

Next, spoon the whipped cream into the mascarpone cheese mixture and whip it in well with the mixer. Now divide it into six serving dishes and refrigerate until ready to serve. 

This can be done the day before, but it will be best if refrigerated in an air-tight container. If you prepare it the day you’re eating it, it can be put in the dessert dishes and left open.

How to serve the pumpkin mousse

First, there are a few ways to serve the mousse. For the pictures I piped the mousse into the dessert dishes. While it looks nice, it can make the mousse lose some of its characteristic mousse bubbles. 

My favorite way to serve a whipped mousse is neatly spooned into the serving dishes then garnished. That way those precious bubbles are not disturbed until your spoon hits them and they pop in your mouth.

I admit I really like pumpkin spice and chocolate flavors together. Therefore, I love to garnish this with a sugar-free chocolate decoration or simple sugar-free chocolate chips. 

Other options could be to sprinkle pumpkin pie spice or cinnamon on the top of the mousse or even sugar-free chocolate shavings. Yes, I’m back to chocolate, but get creative and do what you like!
