Here is the ratio that keeps cream cheese glaze drizzling in ribbons instead of melting into a puddle.
Microwave the finished glaze for about 10 seconds so it turns pourable but not thin; this lets it drizzle in defined ribbons instead of melting into a puddle.
Keep the powdered sugar-to-liquid ratio close to 2:1 by volume for a glaze that holds its shape on top of a warm pancake.
Bonus: an extra pinch of cinnamon whisked into the glaze itself ties the flavor together even more.
