In a medium-sized pot, combine the uncooked rice and 3 cups of almond milk. Bring the mixture to a boil.
Once boiling, reduce the heat to low and let the mixture simmer, stirring occasionally, for about 15 minutes until the rice is almost cooked.
In a separate bowl, whisk together the vanilla protein powder and the remaining cup of almond milk until smooth.
Pour the protein mixture into the pot with the rice.
Add honey, vanilla extract, and salt into the pot, stirring everything together.
Let the mixture simmer for another 15 minutes, stirring frequently until the pudding thickens and the rice is fully cooked.
Once cooked, remove from heat and fold in the Greek yogurt for that extra creaminess and protein kick.
Let the High Protein Rice Pudding cool for a bit before serving.
