Process

Blend mousse ingredients until smooth, scraping the sides as needed
Pour into individual serving jars and refrigerate at least 3 hours, or overnight for optimal thick texture

Press into small dish lined with parchment paper, sprinkle dye-free gems on top, and refrigerate 20 min
Slice into small chunks
When ready to serve melt your dark chocolate in 30 second intervals until almost smooth, then whisk in pb or coconut cream

I love how easy it to just add all of the filling ingredients to a blender, mix, and pour!

FAQ

an I make this dairy‑free?
Yes—use a dairy‑free cottage cheese alternative and swap the ganache peanut butter for coconut cream. Choose a plant‑based protein powder for the mousse and brownie bites.

What if my brownie dough is too sticky?
Extra‑soft dates can make the dough looser. Add 2 tablespoons of chocolate protein powder or a little extra cocoa powder and process again until it firms up.

How long does the mousse need to chill?
At least 3 hours, but overnight gives the thickest, creamiest texture.

Can I prep this ahead of time?
Absolutely. The mousse and brownie bites both store well for 3–4 days in the fridge. Assemble right before serving for the best texture.

Can I freeze it?
You can freeze the mousse and brownie bites separately. Thaw the mousse in the fridge before serving.
