Step-by-Step Instructions 👩🍳
Step 1 — Prepare the Sweet Potatoes
Preheat your oven to 180°C (350°F) and line a loaf pan with parchment paper.
Mash the cooked sweet potatoes until completely smooth.
💡 Tip: Let the potatoes cool before mixing to prevent the eggs from cooking.
Step 2 — Mix the Wet Ingredients
Add the eggs, oil, and Jerusalem artichoke syrup to the mashed sweet potatoes.
Whisk until smooth and creamy.
💡 Tip: Taste the mixture and adjust the syrup if you prefer a sweeter loaf.
Step 3 — Add the Dry Ingredients
Stir in the flour, cocoa powder, baking powder, and a pinch of salt.
Mix only until no dry flour remains.
💡 Tip: Avoid overmixing to keep the loaf light and tender.
Step 4 — Fold in the Chocolate
Gently fold chocolate pieces into the batter.
Transfer the batter to the prepared loaf pan and sprinkle extra chocolate pieces over the top.
💡 Tip: Reserve a few larger chocolate chunks for a beautiful bakery-style finish.
Step 5 — Bake Until Perfect
Bake for 45–50 minutes, or until a toothpick inserted into the center comes out clean or with just a few moist crumbs.
💡 Tip: If the top browns too quickly, loosely cover it with foil during the final 10–15 minutes.
Step 6 — Cool & Slice
Allow the loaf to cool in the pan for about 10 minutes before transferring it to a wire rack.
Slice once completely cooled or enjoy slightly warm with melted chocolate still inside.
💡 Tip: The flavor becomes even richer the following day.
