Bring maple syrup and water to a boil in a 6 qt Dutch oven over medium-high heat.

While the syrup/water is heating, whisk flour, baking powder, and salt in a bowl.

Set the dry ingredients aside.

Grate frozen butter on large holes of a box grater into the flour mixture.

Toss the grated butter with the flour to coat.

Add milk to the butter-flour mixture and stir with a fork until a dough forms.

Once the syrup mixture reaches a boil, use a spoon to drop large clumps of dough into the syrup.

Cover the pot and simmer until the dumplings are cooked through, approximately 10-15 minutes.

Spoon dumplings and sauce into 6 bowls.

Serve immediately.
