Chocolate Chip Muffins
A high initial blast of heat gives these their tall, domed bakery-style top.
What's going on here
The tall, cracked dome on a bakery muffin comes from a burst of steam and gas expansion that happens fastest under high heat — starting these at a notably hotter oven temperature than the rest of the bake needs gives the batter's edges and outer surface a quick head start on setting, while the centre is still rapidly expanding upward from the baking powder's gas and the batter's own moisture flashing to steam. That's what pushes the middle up and out into a dome rather than spreading flat and level the way a lower, steadier heat would produce. Dropping the temperature partway through lets the interior finish cooking through gently, without the outside overbrowning or burning before the centre catches up — the same two-stage logic used in several other bakes in this cookbook, just compressed into a much shorter total time given how small a muffin is.
Ingredients
Dry
- 2 cupsAll-purpose flour
- 3/4 cupGranulated sugar
- 2 1/2 tspBaking powder
- 1/2 tspSalt
Wet
- 1 cupMilk
- 1/2 cupNeutral oil
- 1Egg
- 1 1/2 tspVanilla extract
Add-ins
- 1 1/4 cupsChocolate chips
Instructions
Prep
- Heat the oven to 220°C (425°F) and line a 12-cup muffin tin.
Dry
- Whisk the flour, sugar, baking powder, and salt together.
Wet
- Whisk the milk, oil, egg, and vanilla together.
Combine
- Fold the wet into the dry just until the flour disappears, then fold in the chocolate chips with a few more strokes.
Bake
- Divide among the muffin cups, filling nearly to the top, and bake at 220°C (425°F) for 5 minutes.
Tip: This hot start is what pushes the tops up into a dome rather than spreading flat — don't skip straight to the lower temperature.
- Without opening the oven, reduce the temperature to 180°C (355°F) and continue baking until a skewer comes out clean.

Whether you can make it from staples, right now, with normal gear.
Correctly explains the domed muffin top as a fast-expansion-versus-slow-setting race that a high initial temperature deliberately wins in the batter's favour.
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
Tops came out flat instead of domed
The oven likely wasn't preheated to the full initial high temperature, or the door was opened during that first stage, losing the heat spike that starts the dome forming.
Save a few chips for the top
Pressing several extra chips onto the batter's surface before baking gives visible chocolate on top rather than all of it disappearing into the crumb.
