Here’s another head smacker cookie really should have gone into Volume I but somehow escaped our notice. It came up now in a sideways fashion. We’ve finally gotten around to working on Chocolate Covered Marshmallow Treats. You know that cookie. Everyone does. It’s the one you loved as a child, with a simple cookie base that has marshmallow on top, and is then coated with a thin chocolate shell.
That cookie has scores and scores of different version around the world, but the most common uses some equivalent to a Nilla Wafer® base. So that meant I should start by making… Doh! I’ve never actually worked up a homemade version of Vanilla Wafers. [Sigh]
The result was all we could have hoped for and more. In fact, we discovered that it isn’t a single cookie. It’s actually three.
- Use the full amount of flavor and you’ll get a very pleasant cookie to eat out of hand, that adults will enjoy as much as children.
- Use a moderate amount of vanilla, and you’ll make something very close to the commercial product. Just better in every way. Real butter and real love make a real difference. Kate says that toddlers in Prague were fed a similar cookie whenever treats were earned.
- Reduce the amount of flavor all the way, and you will get the plain, invisible cookie that’s perfect for all the “other” uses these get purchased for. Banana Pudding; El Cheapo Tiramisu; Chocolate Marshmallow Treats; etc., etc., on and on, and suchforth and suchlike.
As always, skip to the bottom if you only want the recipe
This is a simple cookie, and it’s meant to be a simple cookie, so I’m going to try to keep the discussion brief. There weren’t many issues that needed to be addressed. It was really a matter of focusing on what we wanted the cookie to be.
First the Eggs
I wanted this to be a light, crispy cookie with a fair amount of air, that would taste a little buttery without coming off as rich. Most recipes in our books and online resources called for one whole egg to go with each stick of butter. I tested that, along with one egg white, and one egg yolk.
The whole egg won handily, both for ease and flavor. Yes, you can make a good cookie with both egg white and egg yolk, but the whole egg is simpler and, for this use, better.
Wait; Haven’t We Made This Before?
For crying out loud! Butter cookies. Sugar cookies. Shortbread. Alfajories. Spritz Cookies. Snaps. They’re all pretty much the same, right? Just butter, sugar, flour, starch, and egg in slightly different proportions, plus a hit of flavor. Was this one really different, or just a variation on one of our existing and already-tested recipes?
Well… no. I went back and crunched the numbers. These are in the same family but the proportions are distinct enough to earn their own name. Same for the classic French cookies we plan to work up someday, such as Langue du Chat (“Cat’s Tongues” a/k/a Homemade Milanos®), and Tuiles. Those use several egg whites to create a different species within the same genus.
What’s In A Name?
All that recipe comparison work did clarify one thing that was bugging me. These are not a “wafer”!
I am a lawyer in my real life, and have been for 30 years. So I can speak for my profession when I tell you that virtually every non-criminal problem I see comes down to a variation on the theme of frustrated expectations. Person X thought s/he deserved or would get an “A,” ended up with a “B”, and grew angry at that result. So Person X goes back to Person Y to complain, “where is my A?”, and the situation then grows worse because Person Y insists that s/he meant “B” all along. And most of the time both interpretations fit the actual words.
The solution? Define your bloody terms so you can at least know where you really disagree! Try it the next time someone wants to argue about politics. “Exactly what do you mean when you use that word?” You’ll be shocked at how much of your fight disappears, or at least settles down to the amicable question of how words ought to be used.
In any case, I have spent a lot of years getting frustrated over that stupidity, in both my profession and in politics, so I get a little [ahem] picky about calling things by their proper names. A “wafer” is an extremely thin, usually broad cookie like our different Snowflake variations, Tuilles, or Lace Cookies. You can get to that result in many different ways, but that’s the definition.
This cookie does not meet that definition, and thus it isn’t a “wafer.” This cookie is a “Snap”. Harrumph.
We define Snaps as any plain, simple, round cookie that features a clear and focused flavor. Cardamom, Anise, and Black Pepper Snaps feature a single spice. Ginger snaps feature a spice mix with a touch of molasses. But that is the family group, and that is where this cookie belongs. Harrumph I say again! And harrumph for good measure. Harrumph. Harrumph. Harrumph!
Alas, but the outside world does foolish things on occasion. Sometimes it will even [gasp!] ignore it when some large company mislabels what ought to be a Snap as a Wafer. And a wise man has to know his limits. So let us agree on a simple formula, okay?
First, I am in the right. Harrumph. And that means the world is wrong. And thus equity, justice, and fair play are unanimously on my side.
Next, I am not being petty no matter what certain females in my household may choose to imply. Nor childish. Not, not, not!
And no, this isn’t a fight I’m going to win. So how about a compromise?
Let’s agree to call the eating version of this cookie a Vanilla Snap. That’s the tasty one with a full tablespoon of vanilla, which is going to make people sit up and say, “I never thought I’d say it, but these things are capital-G Good.” The weaker versions, which are intended for use in other recipes anyway, can be called by that other name for the sake of allowing the rest of the world to save some face.
Back to your regularly scheduled programming.
Confirmed Again: “Other” Starches Work Better Than Corn Starch
Is the cookie better with a bit of gluten-free starch to supplement the flour? Yes, it is. Cake flour might work too, but we didn’t test it.
Would corn starch work? Yes… but it isn’t as reliable as rice flour, tapioca flour, arrowroot, etc., because you’ll occasionally get a less-done piece that leaves a gummy sensation in your mouth. It’s an effect we wrote about in our book Heritage Cookies of the Old and New World. Corn starch breaks down at a higher temperature than those others, and thus cookies made with corn starch are more likely to have leftover “uncooked starch” in the final product. That’s the underlying problem; it was confirmed again in these experiments; and there’s simply no reason to fight the science. Vanilla Snaps cook until the bottoms brown, which gives a margin of error, but why make use of that margin if you don’t have to?
We usually bake with tapioca starch because it is cheap and readily available in large quantities at our local oriental market. We have tested rice flour and arrowroot too, and found them to be identical. We have read that potato starch fits in too. Corn starch is the only one that requires a higher baking temperature.
Would A Drop Cookie Work?
We always prefer to write up drop cookie recipes when possible, just because they’re so much easier for new people. Refrigerator slice-and-bakes come in second, followed by roll-and-cut cookies, and then by ones you pipe out. What was the best way to go for this one?
The answer depended on what we wanted to do with them. Drop cookies worked fine from the baking perspective, but I simply couldn’t get them to come out even enough to use as a consistent base for the other project. So here is my verdict:
- If you’re after the eat-out-of-hand Vanilla Snap version, make a simple drop cookie and be done with it. You don’t need to do it that way, but you can. Kate swears that they also came out a little lighter and crispier than the rolled-and-cut version, though I couldn’t tell the difference.
- If you’re after a cookie to use in some other role (like the base of a Chocolate Marshmallow Treat), roll them out and use a cookie cutter. These are dead consistent and thus better as an ingredient. The dough is a little on the sticky side, but works fine if you simply dust with flour as needed.
- If you’re trying to jazz things up, add a bit of milk to thin the dough out to a batter, and then pipe out something fancy. You could even sprinkle it with a bit of sanding sugar. It ought to work with a spritz gun as well.
Bake Until The Bottoms Are Good And Tan
Part of the flavor in this cookie comes from actual browning on the bottom. Most cookies want to come out of the oven when they’re still pale, and the edges feel barely set. Leave these in for the full 12 minutes, or until you can see browning around the edges.

CONCLUSION
That’s about it. One forgets that plain old vanilla isn’t that plain at all. It’s a really delicious spice, and it fully deserves to be just as celebrated in a Snap Cookie of its very own. They are as “heritage” as you can get, and well worth making.
