Place the creamy peanut butter into a small mixing bowl.
Sift the whey protein powder into the bowl to prevent clumping.
Fold the protein powder into the peanut butter using a silicone spatula until a thick paste forms.
Add the almond milk and maple syrup to the mixture.
Vigorously whisk the ingredients until the spread is homogenous and smooth.
Store in an airtight container at room temperature for up to 5 days.
