How to Make the Melktert Bombs
Step 1: Mix Up Your Dough
Let’s get our hands a little messy, shall we? In a mixing bowl, combine your cake flour, baking powder, salt, and sugar with a quick whisk. Make a well in the center (like you’re creating a little flour volcano) and pour in your milk and melted butter. Gently mix everything together until you’ve got a soft, slightly sticky dough. Don’t overmix, friends, we want tender puffs, not tough ones!
Step 2: Shape Your Melktert Bombs
Dust your hands with a bit of flour (this dough can be sticky!) and roll the mixture into balls about the size of a golf ball. I find that slightly wet hands actually work even better for shaping. Don’t stress about making them perfect, those little imperfections are what make them homemade with love!
Step 3: The Sizzle and Pop
Heat your oil in a deep pot or fryer to about 350°F (180°C). If you don’t have a thermometer, test it with a tiny bit of dough, it should bubble up immediately and rise to the surface. Carefully drop a few dough balls into the hot oil (don’t crowd them, they need space to party!). Watch them transform into golden puffs as they bob around in the oil, turning occasionally for even browning. This usually takes about 3-4 minutes. When they’re beautifully golden, fish them out and let them cool on paper towels.
Step 4: Create the Dreamiest Filling
While your puffs are cooling down, let’s make that heavenly filling! Mix together your condensed milk and custard until smooth and silky. Transfer this liquid gold to a piping bag fitted with a small round tip. If you don’t have a piping bag, no worries! A zip-top bag with the corner snipped off works perfectly too.
Step 5: Fill ‘Em Up
Once your puffs have cooled enough to handle (patience is hard, I know!), use a skewer or the tip of a knife to make a small hole in each one. Gently pipe the filling into each puff until you feel a slight resistance, that’s how you know they’re perfectly filled. Sometimes a little might ooze out, but that’s just a delicious preview of what’s inside!
Step 6: The Finishing Touch
Mix up some cinnamon sugar in a shallow bowl (I like a ratio of about 1/4 cup sugar to 1 teaspoon cinnamon, but adjust to your taste). Roll each filled puff in this magical dust until completely coated. The warmth of the puffs will help the cinnamon sugar stick beautifully.
Pro Tips for Making the Melktert Bombs
- Oil Temperature: Keep an eye on your oil temperature, too hot and they’ll brown too quickly without cooking inside, too cool and they’ll absorb too much oil and become greasy.
- Filling Strategy: Let the puffs cool just enough to handle, but fill them while still warm for the best texture contrast between the crisp exterior and gooey center.
- Dough Consistency: If your dough feels too sticky, add a tablespoon of flour at a time. Too dry? A splash more milk will do the trick.
- Flavor Boosters: Add a drop of vanilla extract to your filling or a pinch of cardamom to your cinnamon sugar for an extra flavor dimension.
How to Serve The Melktert Bombs
These little bombs of deliciousness shine in so many settings:
- Serve warm with coffee or tea for the ultimate afternoon treat, I promise conversations will pause mid-sentence when people take their first bite!
- Create a dessert platter with these as the star, surrounded by fresh berries and a drizzle of chocolate sauce.
- Pack them (unfilled) for picnics or potlucks, then fill and coat them just before serving for maximum wow-factor.
- Arrange them in a tower for a unique birthday “cake” alternative that everyone will talk about for years.
Make Ahead and Storage
Best Served Fresh
Let’s be honest, these babies are at their absolute peak when freshly made, filled, and rolled in cinnamon sugar. That first bite when the contrast between warm, crisp exterior and cool, creamy filling hits your taste buds is pure magic!
Storing Leftovers
If by some miracle you have leftovers (who are you, and how did you resist?), store them in an airtight container in the refrigerator for up to 2 days. The cinnamon sugar might get a bit soggy, but they’ll still be delicious.
Reheating for Second-Day Bliss
To revive day-old puffs, pop them in a 300°F (150°C) oven for about 5 minutes to crisp up the exterior again. Just be careful not to overheat or the filling might start to leak out!
FAQs
Can I bake these Melktert Bombs instead of frying them?
While frying gives that authentic texture, you can bake them at 375°F (190°C) for about 12-15 minutes. They’ll be different, more like cinnamon rolls than doughnut puffs, but still delicious! Brush with melted butter before rolling in cinnamon sugar.
My filling keeps leaking out. What am I doing wrong?
You might be overfilling them or making the entry hole too large. Try letting them cool a bit more before filling, and make sure your filling isn’t too runny. A smaller piping tip can also help control the flow.
Can I make the dough ahead of time?
Absolutely! You can refrigerate the dough for up to 24 hours. Just bring it back to room temperature before shaping and frying.
What’s the origin of Melktert Bombs?
These delightful treats are inspired by South African milk tart (melktert), a beloved custard-filled pastry. This version combines those flavors with the joy of a doughnut for a cross-cultural dessert explosion!
Can I use a different filling?
Oh my goodness, yes! Try chocolate pudding, dulce de leche, or even a spoonful of Nutella mixed with a bit of cream. The possibilities are endless, follow your dessert dreams!
