Tips & Variations
For extra gooeyness, press a square of dark chocolate into the center before microwaving.
If you prefer a different flavor, you can replace the pistachio butter with peanut butter, almond butter, cashew butter, or even adding more chocolate in the middle!
Top it with berries, a dollop of vegan yogurt, or a drizzle of nut butter for an indulgent finish.
