Preheat your oven to 350°F (175°C).

Grease a bundt pan or tube pan generously with cooking spray or melted butter to prevent sticking.

In a large bowl, mix together the sugar and cinnamon until well combined.

Cut the refrigerated biscuit dough into quarters.

Roll each piece of dough in the sugar-cinnamon mixture until fully coated.

Layer the coated pieces of dough in the prepared baking dish, sprinkling nuts or chocolate chips between layers if desired.

In a medium saucepan, melt the butter over low heat. Add the brown sugar and stir until well-combined and slightly thickened. Pour this mixture evenly over the layered dough.

Place the bundt pan in the preheated oven and bake for about 30-35 minutes, or until golden brown.

Let it cool for a few minutes in the pan before inverting it onto a serving plate.

Prepare to pull apart and enjoy!
