Cinnamon Bun Bread Pudding
Day-old cinnamon buns torn up and rebaked in an egg custard — nothing about a leftover bun goes to waste.
What's going on here
Bread pudding works specifically because stale bread has less water in its structure than fresh, leaving room in the crumb for it to soak up a custard without instantly collapsing into mush — fresh, moist cinnamon buns are already close to saturated and don't absorb nearly as well. Torn rather than sliced, the ragged surfaces of each piece expose more crumb to the custard and soak faster and more evenly than clean-cut cubes would. The custard itself follows the same rule as any baked custard: eggs and dairy in a ratio that sets to a soft, sliceable texture rather than scrambling, baked at a moderate temperature so the proteins coagulate gently. Because the buns already carry their own cinnamon, sugar, and icing, the added custard here is left plainer than a standard bread pudding's — mostly egg, milk, and vanilla — so it doesn't compete with flavour that's already baked into the bread.
Ingredients
Base
- 6Day-old cinnamon buns, torn into chunks

Custard
- 4Eggs
- 1 1/2 cupsMilk
- 1/2 cupHeavy cream
- 1/4 cupGranulated sugar
- 1 1/2 tspVanilla extract
- 1/2 tspGround cinnamon
Finish
- 2 tbspIcing (powdered) sugar, for dusting(optional)
Instructions
Base
- Tear the cinnamon buns into rough chunks and scatter them in a greased 9x9 pan, icing and all.
Tip: Tearing rather than slicing gives ragged edges that soak up the custard faster and more evenly than clean cuts.
Custard
- Whisk the eggs, milk, cream, sugar, vanilla, and cinnamon together until smooth.
Assemble
- Pour the custard evenly over the torn buns, pressing them down gently so everything is submerged. Let sit so the bread can soak.
Tip: This soak matters — bread pudding baked without it has a dry top layer and a custardy bottom instead of an even texture throughout.
Bake
- Bake at 165°C (330°F) until puffed, golden, and just set in the centre — it should still have a gentle wobble.
Serve
- Let stand 10 minutes before serving, dusted with icing sugar if you like.

How well the formula holds up against known working ratios.
Whether the method builds flavor or merely combines ingredients.
How deliberately moisture, gluten, starch, and fat are controlled.
How much margin for error the recipe leaves a home cook.
Whether you can make it from staples, right now, with normal gear.
A genuinely sound use for stale baked goods, built on real custard-setting principles rather than just soaking bread in egg. Forgiving and hard to get wrong.
Scored on the science of cooking — ratios, flavour development, texture control, how forgiving the method is, and whether you can make it from what's in the cupboard. Not a measure of how much you'll like it.
Tips for this recipe
Buns aren't stale yet
Leave freshly baked buns uncovered at room temperature for a few hours, or a day ahead is even better. Fresh, fully moist buns don't have the spare capacity to absorb a custard properly.
Pudding came out soggy
Either the bread wasn't stale enough to begin with, or it didn't get its full soak time before baking. Give it the full 15 minutes, pressing the pieces down so the custard actually penetrates rather than pooling underneath.
