• Start by preheating your oven to 180°C (350°F). Grease a 2 lb loaf pan (about 23 x 14 cm or 9 x 5.5 inches) with a bit of butter, then line the base and sides with parchment paper. Leave some overhang so it’s easy to lift out later.
• In a large mixing bowl, add your eggs, white sugar, and light brown sugar. Whisk them together until the mixture turns pale and slightly frothy, about one minute. That’s when you know the sugar has started to dissolve nicely.
• Pour in the oil, pumpkin purée, Greek yogurt, and vanilla extract. Whisk until everything is smooth and fully combined. You should have a creamy golden batter with that lovely pumpkin scent.
• Sift together your flour, pumpkin spice, baking powder, baking soda, and salt right into the bowl. Using a spatula, gently fold the dry ingredients into the wet. Stop when you still see a few streaks of flour—don’t overmix, or you’ll lose that soft, tender crumb.
• Now, split the batter evenly into two bowls. If you’d like more of that pumpkin color in your marbling, leave a couple extra spoonfuls in the plain pumpkin bowl.
• In one of the bowls, whisk in cocoa powder, a touch of Greek yogurt, and a pinch of espresso powder. Mix just until everything is combined. You should now have two batters, one pumpkin, one chocolate—ready for swirling.

Marble and Bake the Bread

• Now darling, this is where the magic happens, the part that turns an ordinary loaf into something truly special.
• Spoon a few generous dollops of your pumpkin batter into the bottom of the prepared loaf pan, and use the back of a spoon or a small offset spatula to smooth it out evenly.
• Then add a few spoonfuls of the chocolate batter right on top and spread it gently. Keep alternating layers pumpkin, then chocolate until you’ve used up all the batter.
• Don’t worry about perfection, sweetheart, the beauty is in those natural swirls.
• Now take a skewer or a thin-bladed knife and gently swirl through the batter in a loose figure-eight motion. Dip in, lift out, and dip again here and there so the two batters mingle but don’t completely mix. A few soft swirls will do; too much and you’ll lose that pretty pattern.
• Slide the pan into the center of your oven and bake for 50 to 55 minutes, until the top turns golden brown and a toothpick inserted in the middle comes out clean or with just a few moist crumbs.
• If you notice the loaf getting too dark too quickly, cover it loosely with a sheet of aluminum foil and let it finish baking gently.
• When it’s done, take it out and set the pan on a wire rack to cool for about 10 minutes. Then lift the bread out carefully using the parchment overhang and let it cool completely on the rack.
• Once cooled, you’ll see that gorgeous marbled pattern inside, soft pumpkin with ribbons of rich chocolate running through it.
• Slice it thick, serve it warm, and watch everyone smile after the first bite.

Maple Icing (Optional but Highly Recommended)

• this glaze is what takes your loaf from cozy to downright irresistible. It adds that glossy maple sweetness that pairs beautifully with both the pumpkin and the chocolate.
• In a small bowl, whisk together powdered sugar and pure maple syrup until smooth and lump-free.
• If the glaze feels a little too thin, don’t worry, just add a bit more powdered sugar, about 30 grams (¼ cup) at a time, until it’s thick enough to coat the back of your spoon.
• Once your bread has completely cooled, drizzle the maple glaze generously over the top, letting it drip down the sides.
• It will start to set after about 10 minutes, forming a lovely thin crust on top.
• Now darling, slice the bread thick and serve it with a warm cup of coffee or spiced tea.
• That soft pumpkin crumb with the hint of chocolate and maple glaze is pure autumn comfort in every bite.
