Preheat your oven to 350°F. Butter a 9x13-inch baking dish generously.

Slice your peaches into 8 wedges total — about 4 slices per peach. Remove the pits carefully.

Unroll the crescent dough and separate it into 8 triangles along the perforated lines. Place one peach slice at the wide end of each triangle. Sprinkle a small pinch of cinnamon and about a teaspoon of sugar directly on the peach.

Roll up each triangle from the wide end to the point, wrapping the peach snugly inside. Place each rolled dumpling seam-side down in your prepared baking dish.

In a medium bowl, combine melted butter, remaining sugar, cinnamon, and vanilla extract. Whisk until the sugar mostly dissolves. Pour this mixture evenly over all the Peach Crescent Dumplings.

Carefully pour the soda around the edges of the pan — not directly over the dumplings.

Bake for 35-40 minutes until the dumplings turn deep golden brown and the sauce bubbles vigorously.

Let the Peach Crescent Dumplings cool for about 10 minutes before serving.
