Belgian buns are soft, sweet yeast buns, commonly found in British bakeries, filled with dried fruit and often finished with lemon icing and a cherry. This version rolls lemon curd and raisins into an enriched dough, so each bun has a tender crumb and a bright, tangy swirl. The dough is straightforward to make, but it needs time to rise before baking.
Ingredients
- 3 1/2 cups (450 g) bread flour, plus a little extra for dusting
- 2 tablespoons (25 g) granulated sugar
- 2 1/4 teaspoons (7 g) instant yeast
- 1 teaspoon (6 g) fine salt
- 3/4 cup (180 ml) whole milk, warmed to 100–110°F (38–43°C)
- 1 large egg (about 50 g without the shell), at room temperature
- 5 tablespoons (70 g) unsalted butter, softened and cut into pieces
- 1/3 cup (100 g) lemon curd
- 1/2 cup (75 g) raisins or currants
- 1 large egg (about 50 g without the shell), for the egg wash
- 1 tablespoon (15 ml) milk, for the egg wash
- 1 cup (120 g) powdered sugar
- 1 1/2 tablespoons (22 ml) lemon juice, plus a little more if needed
- 10 glacé cherries (about 100 g), optional, for topping
Instructions
- Mix the dough. In a large bowl, stir together the flour, sugar, instant yeast, and salt. Keep the salt and yeast from sitting in a concentrated pile together before mixing; direct contact can slow the yeast. Pour in the warm milk and add the dough egg. Mix with a sturdy spoon until there are no large dry patches. The dough will look rough and slightly sticky at this stage.
- Knead in the butter. Add the softened butter a few pieces at a time, working each addition into the dough before adding the next. Knead on a lightly floured counter for about 8 minutes, or in a stand mixer with a dough hook for 5–6 minutes on low to medium-low speed. The finished dough should feel smooth, elastic, and soft, though it may remain a little tacky. Add flour a teaspoon at a time only if it is so sticky that you cannot handle it; too much flour makes the buns dry.
- Let the dough rise. Shape the dough into a ball and place it in a lightly greased bowl. Cover the bowl and leave it at room temperature for 75 minutes, until the dough has roughly doubled. A cool room can make the rise take longer, so judge by the dough’s size rather than the clock alone. If it has not expanded much after 75 minutes, give it more time in a comfortably warm, draft-free spot.
- Fill and shape. Line a large baking sheet with parchment paper. Turn the risen dough onto a lightly floured counter and roll it into a rectangle about 12 by 16 inches (30 by 40 cm), with one long edge facing you. Spread the lemon curd in a thin, even layer, leaving a 1/2-inch (1 cm) border along the far long edge so the roll can seal. Scatter the raisins or currants evenly over the curd. Starting at the long edge nearest you, roll the dough into a log, keeping it snug without squeezing out the filling.
- Cut the buns. Pinch the seam closed and turn the log seam-side down. With a sharp serrated knife or unflavored dental floss, cut it into 10 equal pieces, each about 1 1/2 inches (4 cm) wide. A gentle sawing motion helps keep the spiral round. Set each piece cut-side up on the lined sheet, leaving about 2 inches (5 cm) between them. If a little lemon curd escapes, tuck it back into the spiral rather than wiping the filling away.
- Proof and heat the oven. Cover the buns loosely with lightly oiled plastic wrap or a clean towel and leave them to rise for 40 minutes. They should look puffy and close to one another, but need not fully double. During this rise, heat the oven to 375°F (190°C). Near the end of the proof, whisk the egg-wash egg with 1 tablespoon (15 ml) milk. Brush a thin coat over the exposed dough, taking care not to flood the seams.
- Bake the buns. Bake for 16–18 minutes, until the tops are golden brown and the centers look set. Check the center of a bun with a food thermometer: because this is an egg-containing baked recipe, follow the USDA FSIS safe minimum of 160°F (71°C) for egg dishes. If the tops brown too quickly while the centers are still baking, loosely cover the sheet with foil for the remaining minutes. Move the buns to a wire rack and cool for 20 minutes before icing.
- Ice and finish. Stir the powdered sugar with 1 1/2 tablespoons (22 ml) lemon juice until smooth and thick enough to drizzle. Add extra lemon juice a few drops at a time if it is too stiff, or a spoonful of powdered sugar if it is too runny. Spoon or drizzle the icing over the cooled buns and top each with a glacé cherry, if using. Let the icing set for about 10 minutes before serving.
Tips
- Measure flour carefully. Weighing the flour gives the most dependable dough. If measuring by cups, fluff the flour first, spoon it into the cup, and level it rather than packing it down. Too much flour is a common reason sweet buns turn dense.
- Keep the milk warm, not hot. Milk that feels gently warm is suitable; very hot milk can damage yeast and delay the rise. If using active dry yeast instead of instant, stir it into the warm milk with a pinch of the measured sugar and wait 5–10 minutes for it to foam before mixing the dough.
- Use thick lemon curd. A loose or runny curd is more likely to leak from the roll and make the bottoms sticky. If your curd is especially soft, chill it until spreadable, and leave the border around the dough clear so the seam can close.
- Do not rush the proof. Dough rises according to room temperature and yeast activity. If the shaped buns still feel firm and look small after 40 minutes, wait another 10–20 minutes rather than putting them straight into the oven. Conversely, avoid leaving them until they collapse or lose their shape.
Serving Suggestions
Serve Belgian buns slightly warm or at room temperature, once the lemon icing has had a few minutes to set. They are rich enough to enjoy on their own with tea or coffee, and the tart lemon filling makes them a natural choice for a breakfast or afternoon snack. For a brunch spread, set them out with fresh berries, sliced pears, or a bowl of plain yogurt so there is something cool and fresh alongside the sweet pastry.
If you want to serve them warm, heat individual buns briefly in a low oven rather than microwaving a whole tray. The icing will soften, so add it after warming if you have not iced the buns yet. These are also easy to portion: separate the spirals gently with a small spatula if they have baked close together, and place them on a platter with the cherry side facing up.
Variations
Use currants or sultanas. Currants are small and distribute evenly through the swirl; raisins make a slightly juicier, more noticeable filling. Sultanas work well too. If your dried fruit is very firm, cover it with hot water for 10 minutes, then drain and dry it thoroughly before using. Extra moisture on the fruit can make the spiral slippery.
Swap the citrus. Orange curd and finely grated orange zest make a sweeter, less tart bun. You can also use a thick apricot jam in place of lemon curd, though the result will be fruitier and less sharp. Avoid runny jam, which can escape as the buns bake.
Change the finish. Leave off the cherries for a simpler iced bun, or replace the lemon icing with a thin vanilla glaze made by mixing powdered sugar with milk. For a little extra citrus aroma, stir 1 teaspoon (about 2 g) finely grated lemon zest into the icing. Add the zest only after grating the yellow peel, not the bitter white pith.
Make smaller buns. Cut the dough log into 12 pieces instead of 10 for smaller portions. Arrange them with space between each one and begin checking for doneness around 14 minutes; the exact time depends on their size and your oven. Keep the same dough and filling quantities, and use the visual and temperature checks in the baking step rather than relying only on the shorter estimate.
Storage and Reheating
Once cool, keep the buns in an airtight container at room temperature for up to 2 days. The icing may become a little sticky in a humid room, but the buns should remain soft. Because these are baked goods with a relatively low-moisture filling, refrigeration is not needed for short-term storage; chilling them can make the dough seem firmer and less tender. Do not leave them uncovered, since the exposed spiral dries out quickly.
For longer storage, freeze the completely cooled buns in a freezer-safe container or well-wrapped freezer bag for up to 2 months. For the neatest finish, freeze them without icing and add the glaze after thawing. Thaw at room temperature for about 1–2 hours, then warm in a 300°F (150°C) oven for 5–8 minutes if desired. If already iced, thaw them uncovered so condensation is less likely to make the glaze wet. As with other perishable foods, refrigerate any filling or curd separately according to its package directions, and do not leave food that requires refrigeration at room temperature for more than 2 hours.
Frequently Asked Questions
Are Belgian buns actually from Belgium?
The name is used for a familiar sweet bun sold in British bakeries, but its precise origin is not firmly established. Bakery versions vary: some use lemon curd, some use other fruit fillings, and the icing and cherry topping are not universal. This recipe follows the British-style bakery format of a fruit-filled spiral with lemon icing.
Can I make the dough the night before?
Yes. After kneading, put the dough in a covered, lightly greased bowl and refrigerate it overnight, for up to about 12 hours. The next day, let it sit at room temperature until workable, then roll, fill, and shape it. The second rise may take longer than 40 minutes because the dough will still be cool; bake when the buns look puffy rather than forcing the clock.
Why did the filling leak out?
A small amount of curd escaping is normal, but a large pool usually means the filling was too runny, the dough was overfilled, or the roll was squeezed while cutting. Use a thin layer of thick curd, keep the far edge free of filling, and seal the seam. A sharp knife or dental floss also helps slice the log without compressing it.
Can I use plain all-purpose flour?
Yes. Replace the bread flour with the same weight, 3 1/2 cups (450 g), of all-purpose flour. The buns may be a little less chewy and slightly more delicate, but they will still rise and bake well. Since flour absorbs liquid differently by brand and measuring method, hold back a tablespoon of milk at first and add it only if the dough feels unusually dry after mixing.
Can I prepare Belgian buns without a stand mixer?
Absolutely. Mix the ingredients in a large bowl with a spoon, then knead by hand on a lightly floured counter. The butter makes the dough feel slippery at first; continue kneading and it will gradually become more cohesive and elastic. A mixer saves effort, but it is not essential for this quantity of dough.
How do I know the buns are baked through?
Look for golden tops, set centers, and dough that springs back lightly when pressed. A food thermometer provides an additional check: the center should reach at least 160°F (71°C), the USDA FSIS safe minimum for an egg dish. If the buns are browning before the middle is ready, cover them loosely with foil and continue baking until done.
