Chocolate Wafer
Čokoládová oplatka is the Czech chocolate wafer bar: several thin, crisp sheets of baked batter wafer sandwiched with a sweet chocolate or cocoa cream, then sold as a bar that is often dipped in or coated with chocolate or cocoa coating, like the familiar Tatranky, Horalky or Kávenky. Under Czech food law (vyhláška 18/2020 Sb.), oplatky (wafers) belong to trvanlivé pečivo, the shelf-stable bakery goods.
In practice
How to store
- On the counter
Keep sealed in a cool, dry, dark place. Producers usually recommend 10–25 °C. Once opened, eat within a day or two or close the pack tightly, because the wafer picks up moisture from the air and turns soft and leathery. Heat makes the coating melt or bloom.
- In the fridge
Not needed, and usually not a good idea: the humidity and condensation when you take the bar out can soften the wafer and cause sugar bloom on the coating. Chill briefly only in very hot weather, kept in an airtight box.
- In the freezer
Possible in airtight packaging for a few months, for example when you have a stockpile. Let the bar come to room temperature in its sealed wrapper before opening so condensation does not form on it. Some people like coated bars eaten straight from the freezer, but the texture changes a little.
How to choose
Read the wrapper rather than the name, because Czech wafer bars vary a lot. Check the ingredients list for the share of chocolate and coating. Many bars use 'kakaová poleva' (cocoa coating made with vegetable fat), not real chocolate, and the label says which one you are getting. Look at the fat source if that matters to you; palm and coconut fat are common. If you are allergic, check the allergen information in bold and the 'může obsahovat' (may contain) line for nuts and peanuts. A good bar has an intact wrapper, unbroken wafer and no grey bloom on the coating. Bloom does no harm, but it means the bar has been stored too warm. Bars sold as Tatranky or Horalky in Czechia may come from either the Czech Opavia factory or the Slovak Sedita factory, and their recipes differ.
What to swap in
Best swap
Another layered wafer with cocoa or hazelnut cream, such as a plain cocoa-cream wafer bar or plain wafer sheets spread with chocolate cream. The texture is the same and only the coating is missing.
In a pinch
A chocolate-covered crisp biscuit or a crisped-rice chocolate bar gives a similar crunch and cocoa flavour, though without the airy layered texture of wafer.
Preparation
Eaten straight from the wrapper, no preparation needed. For desserts, chop or crumble the bars with a knife. Cut them cold so the filling doesn't smear. For a no-bake cake or a topping, crush them in a bag with a rolling pin.
Don't toss it
If a bar has gone soft or has broken into crumbs, use it in baking: fold the pieces into brownie or muffin batter, scatter them over ice cream or a cream dessert, or mix them with melted chocolate and a little butter to make a crunchy layer for a no-bake cake.
In the kitchen
Cooking
Wafer bars are made to eat as they are. In the kitchen they are used cold: chopped as a topping for ice cream, yoghurt or tvaroh desserts, layered into no-bake cakes and dessert glasses, or pressed onto the sides of a cream cake. Add them just before serving, because the wafer softens within minutes of touching moist cream. Baking them into dough is possible, but the crisp texture is largely lost, and coated bars melt.

What it is
Čokoládová oplatka is the Czech chocolate wafer bar: several thin, crisp sheets of baked batter wafer sandwiched with a sweet chocolate or cocoa cream, then sold as a bar that is often dipped in or coated with chocolate or cocoa coating, like the familiar Tatranky, Horalky or Kávenky. Under Czech food law (vyhláška 18/2020 Sb.), oplatky (wafers) belong to trvanlivé pečivo, the shelf-stable bakery goods. They are made by baking a thin layer of batter or dough by contact between heated plates in a mould. The finished wafer is very dry, which is why the bars keep for months. Czech shops sell them everywhere, from supermarket confectionery shelves to petrol stations and school canteens, and they are a standard snack for trips, hikes and lunch boxes.
How it tastes
The wafer leaves are almost neutral, lightly toasted and only faintly sweet. Most of the flavour comes from the filling, a fat-based cream that tastes of cocoa and sugar and melts quickly on the tongue. Where the bar is coated or edged with chocolate or cocoa coating, you get a slightly bitter, firmer layer on top. The appeal is the contrast between the shattering-crisp, airy wafer and the smooth cream. Variants may add hazelnut, peanut, coffee or mint flavours.

Varieties
Tatranky
– the classic Czech wafer from Opava, made by Opavia (today part of Mondelēz). Layered wafer with chocolate, hazelnut, peanut, milk and other fillings. The chocolate version has dark cocoa coating on the edges. A Slovak version made by Sedita in Sereď is also sold.
Horalky
– a peanut-filled wafer bar from Sedita in Sereď, Slovakia, with its edges dipped in cocoa coating. It is popular across Czechia and Slovakia and is often mentioned in the same breath as Tatranky.
Kávenky and other flavoured wafers
– wafer bars with a coffee-flavoured or other cream filling, sold alongside the chocolate ones.
Chocolate-enrobed wafer bars
– bars fully covered in milk chocolate, such as KitKat or Siesta. These sit on the same shelf and are often labelled 'čokoládová tyčinka s oplatkou' (chocolate bar with wafer).
Wafer sheets (oplatky na dort)
– large plain wafer sheets sold for home baking. Home cooks spread them with chocolate, nut or tvaroh cream and stack them to make a homemade layered wafer cake.
Related but different products
– lázeňské oplatky (spa wafers, such as Kolonáda) are large round thin wafers with a thin sweet filling. American-style 'chocolate wafers' are dough-based cocoa biscuits, not batter wafers, and are a different product altogether.
History
Layered cream-filled wafer bars have a long history in Czech and Slovak confectionery. The Fiedor family firm in Opava, founded in 1840, was one of the roots of today's Opavia company. Tatranky have been made in Opava since 1945. They got their name from their original triangular shape, which was meant to recall the peaks of the Tatra Mountains. In 1965, Sereď in Slovakia began producing a peanut-filled version under the name Horalky. After Czechoslovakia split, the Czech and Slovak producers disagreed over who owned the names. A settlement in 2006 allowed both to use Tatranky and Horalky as long as the wrappers look visibly different.
Science
Wafer batter is a thin, runny mixture of wheat flour and water with small amounts of fat, emulsifier and raising agent. It is baked for a short time between hot metal plates. The water flashes off as steam, leaving a light, porous, very dry sheet with a honeycomb pattern. The low water content is what makes it crisp. Under Czech law, trvanlivé pečivo such as wafers may contain at most 10 % water. Because the wafer absorbs moisture from the air easily, the filling is fat-based rather than water-based: a cream of vegetable fat, sugar and cocoa that does not soak into the leaves. Packaging protects the bar from humidity. Coatings labelled 'kakaová poleva' use vegetable fats in place of cocoa butter. They set more easily and are less sensitive to heat than real chocolate, but taste different.
Sourcing and ethics
The main sourcing issues are cocoa and palm oil. Cocoa is grown mainly in West Africa, where child labour and deforestation are well-documented problems. Some brands take part in certification or company sustainability programmes, and the wrapper says so. Palm and palm kernel fat are common in fillings and coatings, so look for an RSPO certification mark if this matters to you. Some producers also run their own wheat sourcing programmes. The best-known Czech brands are made in Czechia or Slovakia, often in factories with a long local history, but several now belong to multinational groups.
