A snickerdoodle is a sugar cookie rolled in cinnamon sugar. These are the muffin version, and the cinnamon sugar goes on after baking rather than before, which changes everything about how they taste.

Two dozen mini muffins, twenty minutes of prep, fifteen in the oven. Then each one gets dipped in melted butter and rolled in cinnamon sugar while still warm.

The coating is the whole recipe

A third of a cup of melted butter and two thirds of a cup of cinnamon sugar, and both numbers look excessive for twenty four small muffins until you understand what they are for.

this …

The muffin itself is deliberately plain. There is no cinnamon in the batter at all, only a quarter teaspoon of nutmeg. That plainness is the point, because it gives the coating something neutral to sit against.

Dipping in butter first is what makes the sugar stick in a thick layer rather than a dusting. You end up with a crisp sweet shell around a soft plain crumb, which is exactly the contrast a snickerdoodle cookie has.

Nutmeg instead of cinnamon in the batter

A quarter teaspoon, and it is easy to dismiss as a rounding error.

Nutmeg is warm and slightly musky and it sits underneath cinnamon rather than competing with it. Putting cinnamon in the batter as well would flatten the whole thing into one note. The nutmeg gives the crumb its own quiet character so the muffin is not simply a vehicle for the outside.

Cream the butter properly

Five to seven minutes with the sugar, until light and fluffy.

That is a long time and most people stop at two. What you are doing is beating air into the fat, and that trapped air is a significant part of what lifts these. There is baking powder here as well, but a properly creamed base gives a finer, lighter crumb than baking powder alone can manage.

The mixture should visibly pale and increase in volume. If it still looks yellow and dense, keep going.

Stop mixing when the flour disappears

The dry ingredients get combined separately, then added to the creamed mixture just until moistened.

Just until moistened is the standard muffin instruction and it exists because overmixing develops gluten. Gluten is what you want in bread and what you do not want in a muffin, where it produces a chewy, tunnelled, tough crumb.

The batter should look slightly lumpy when you stop. That is correct.

Two thirds full, not to the top

Greased miniature muffin cups, filled two thirds.

These rise properly, unlike some denser muffin recipes, so leaving headroom matters. Filled to the top they dome over the edges and spread into each other, and you lose the clean shape that makes them easy to dip.

Fourteen to sixteen minutes

350F, until a toothpick inserted in the centre comes out clean.

Mini muffins bake fast and the window is narrow. Start checking at fourteen. Overbaked mini muffins go dry very quickly because there is so little mass holding moisture.

Cool five minutes, then dip warm

This timing is the one thing to get right.

Five minutes in the pan, then out onto racks, then dipped while still warm. Warm muffins are what make the butter soak in slightly rather than sitting on the surface, and warm surfaces hold cinnamon sugar far better than cool ones.

Wait until they are completely cold and the butter congeals on the outside and the sugar slides off in patches. Dip them straight out of the oven and they are too fragile and will tear.

Work quickly. Butter in one bowl, cinnamon sugar in another, muffin into the butter, turn to coat, then into the sugar and roll.

Making your own cinnamon sugar

Two thirds of a cup is more than most shop-bought jars hold, and it is trivial to make.

The standard ratio is four parts sugar to one part ground cinnamon. So for two thirds of a cup, that is roughly half a cup plus a couple of tablespoons of sugar to about two and a half teaspoons of cinnamon. Whisk them together in a shallow bowl wide enough to roll a muffin in.

Any leftover keeps indefinitely in a jar and is useful on toast and porridge.

Serving them

Warm, which is how the recipe finishes, and it is right. These are best within an hour of coming out of the oven while the coating is still crisp and the inside is still soft.

They keep two days in an airtight container, though the sugar shell softens overnight and absorbs into the muffin. Still good, just different.

Around 116 calories each, which for a mini muffin coated in butter and sugar is more reasonable than it sounds.

Making them full size

The batter works in a standard muffin tin and gives you about ten. Increase the bake to eighteen to twenty two minutes and check with a toothpick. The ratio of coating to crumb drops, since larger muffins have less surface area relative to their volume, so they taste less intensely of cinnamon sugar.

Getting the dip even

Use a bowl narrow and deep enough that the melted butter pools rather than spreading thin. A cereal bowl works better than a wide dish, and you will use less butter overall.
