Crafting 3 Ingredient Keto Coffee Mousse

I’ve always been a big fan of coffee – and coffee mousse…even better! Not only is it great for energy, but it tastes amazing. There’s something about that subtle hint of caramel with a nutty undertone that just dances on your palate. Luckily, coffee is a staple on the ketogenic diet so it’s totally okay to have, and mix with your favorite creams and sugar-free sweeteners (like allulose or Monk fruit), and maybe even a sprinkle of cinnamon (my favorite!).

So when I came across an Instagram post where they crafted the smoothest coffee mousse I’ve ever seen with just a few ingredients, I knew I could easily keto-fy this luxurious treat. And it’s super easy to make, just blend the ingredients until it resembles a whipped cream texture (like 2-3 minutes with a food processor), then enjoy!

I have to warn you though, this is for coffee lovers only as the espresso powder is very strong with this one. So if you prefer a mild coffee taste, you can always adjust by adding more water and less coffee (or use just regular instant coffee powder). As long as you blend it properly, the mousse will turn out beautifully and you’ll want to eat it on the regular. And who can beat a truly 3-ingredient recipe that only takes 5 minutes to make from start to finish!?

Ingredients for Keto Coffee Mousse

Just 3 really real ingredients. Instant espresso powder, sweetener of choice, and water. Yes, I even included the water.

• Instant Espresso Powder – You need an instant coffee base for a coffee mousse. Any instant coffee will do really – make sure it’s instant (for real, you don’t want regular ground coffee). I chose Cafe Bustelo espresso powder mainly because it was on sale, but also because I love this brand when it comes to anything coffee. Their high quality beans just make any coffee recipe super bold and rich. I always reach for that yellow and red label in the coffee aisle!
• Sweetener – Preferred sweeteners are allulose, Monk fruit, or stevia if you’re following the keto diet. Feel free to use any type of sweetener you like according to your dietary goals.
• Water (or Ice) – Use filtered or distilled water, or you could even add ice with water instead. As long as you use some sort of blender or food processor that will really blend it smoothly, your coffee mousse will turn out great either way. It’s really just a matter of your personal preference.

How to Make Keto Coffee Mousse

The key to a light and fluffy texture coffee mousse involves just a couple steps.

• Add espresso powder, water, and sweetener of choice to a blender or food processor. I use the food processor attachment that came with my emulsifier.
• Blend for about 2-3 minutes until it resembled whipped cream with stiff peaks.
• And that’s it! Make sure the flavor profile is to your liking – this recipe is strong with a capital S – so you might have to adjust the amount of water if it’s too bold for you.
