The Next-Level Babka: chocolate , Walnut, and Orange

First things first, we gotta activate the yeast. In a saucepan, get your sugar and milk all cozy and warm (think lukewarm bath, not boiling inferno). Take it off the heat, sprinkle in that crumbled yeast, and let it get friendly with the warm milk. Now, pour this yeasty milk mixture over the flour and stir it up until it's a happy little dough ball. Cover it with plastic wrap and let it rise like a champion for about 15 minutes.

In a bowl ,Grab those yolks, whole eggs, salt, and sugar and whisk them together until they're light and fluffy . Add the Greek yogurt, citrus zest, and vanilla, then gently fold in the sifted flour. Time to get your hands dirty! Knead that dough until it's smooth and satiny. Here comes the good stuff: slowly alternate adding the oil and softened butter (think five installments) while continuing to knead. Imagine you're folding the dough over itself, building strength. When it detaches from the bowl and feels like a dream, give it a few good "punches" for good measure. Plop it back in the greased bowl, cover it lovingly with plastic wrap, and send it to chill in the fridge for a cool 14 hours.

Here's where things get artistic. Brush your rolled-out dough with some beaten egg - it's like a pre-bake tan! Spread a generous portion of the chocolate filling all over that beautiful dough. Now, repeat this process with the remaining dough and filling. Time to braid! Take two of the rolled-up pieces, start braiding from the center, and pinch the ends to seal the deal. Place it snuggly in your prepared loaf pan. Repeat this braiding magic with the remaining dough and filling. Cover it with a kitchen towel and let it rise again at room temperature until it doubles in size - think a fluffy cloud! This might take around 45 minutes, but remember, good things come to those who wait (and who have a warm kitchen). Brush it again with that beaten egg - it's like a golden pre-bake glow-up! Bake it at 400°F (200°C) for 9 minutes to get things started. Then, lower the heat to 320°F (160°C) and bake for another 45 minutes. Let this beauty cool down a bit before you slice into it (trust us, the wait is worth it!). For an extra decadent touch, drizzle on some homemade chocolate glaze if you're feeling fancy.
