PEANUT BUTTER MASCARPONE JARS – Keto, Low Carb, Gluten Free, Sugar Free

Today (October 28th) is my birthday! (It’s already 28th here in Japan.) And I’m publishing one recipe like I did last year too. (I published this Cinnamon Chocolate Coconut Flour Cookies recipe last year.)

Why is peanut butter so irresistible? I was okay for a long time without eating peanut butter, but why can’t you just stop eating it once you have a bite…? (LOL) I didn’t like peanut butter as a kid. Probably it’s because almost all of the peanut butter jars you can get here in Japan contain vegetable oil, sugar and additives, and I didn’t think it tasted good as a kid… I stayed away from peanut butter for a very very long time. Peanut butter is not so popular in Japan either anyway. And then, if I remember correctly, it was when I went to New Zealand to study in 2013. I tried peanut butter for the first time in how many years? Anyway it was delicious! I looked at the ingredients and I understood why. It was made with only one ingredient; dry-roasted peanuts. After I came back to Japan, I found one brand of peanut butter made only with peanuts, which are organic too.  I only can get that jar on the Internet or at one shop located seven train stations away though!

Anyway, I mixed peanut butter with mascarpone cheese in this recipe with crushed almond chocolate cookies at the bottom. When I started this way of eating, one of my favourite desserts was mascarpone mixed with unsweetened cocoa powder, vanilla and stevia, which is ridiculously easy to make yet so delicious. I opened the lid of a container of mascarpone, just added cocoa, vanilla and stevia, stir, put the lid back on and put it back to the fridge so that I could eat it anytime I wanted just with one spoon.

When I was making this recipe video, it was August and very hot. (And I’m somehow publishing in October 😛 ) When piping into jars, the mixture was kind of too runny. So, I suggest that you refrigerate for 20 – 30 minutes before piping, if necessary, depending on the room temperature, and then pipe into jars and chill again for another one or two hours. I made this recipe video soon after my father’s death so the music is a bit mellow 😛

You can eat without the chocolate base, but I personally think that the mousse tastes better with the chocolate base.
