Add the carrots to a medium saucepan and fill with enough water to cover them.
Place the saucepan over medium-high heat and bring to a boil. Boil for 5 to 6 minutes, until the carrots are fork-tender but still have a little bite remaining.
Drain the water from the saucepan and return the carrots to the stove.
Add the salted butter, dark brown sugar, garlic powder, salt, and pepper.
Continue cooking, stirring occasionally, for 5 to 6 minutes until the brown sugar has dissolved and the glaze begins to thicken and lightly coat the carrots.
Remove from the heat and serve warm, spooning any remaining glaze over the carrots.
