Mix the wet base. In a medium bowl or jar, whisk together 1 cup milk, 1/2 cup pumpkin purée, 1/2 cup plain Greek yogurt, 1 scoop protein powder, 1–2 tablespoons maple syrup, 1 teaspoon vanilla extract, 1–1.5 teaspoons pumpkin pie spice, and a pinch of salt until smooth.
Add chia seeds. Stir in 3 tablespoons chia seeds. Whisk well for 30–45 seconds to distribute evenly and prevent clumps.
Rest and stir again. Let the mixture sit for 5–10 minutes, then stir again to break up any settling chia.
This step helps the pudding thicken evenly.
Chill. Cover and refrigerate at least 3–4 hours, or overnight for best texture. It will thicken to a spoonable, pudding-like consistency.
Adjust texture. If it’s too thick, stir in a splash of milk. If it’s too loose, add 1 more teaspoon chia and rest another 15–20 minutes.
Serve with toppings. Spoon into bowls or jars and finish with crushed nuts, a dollop of yogurt or whipped cream, a sprinkle of cinnamon, or granola for crunch.
