Preheat and preparePreheat your oven to 180°C (350°F). Line a muffin tin with paper liners or lightly grease with cooking spray.

Mix wet ingredientsIn a large mixing bowl, whisk the egg with sugar and vanilla sugar until light and frothy. This helps incorporate air, contributing to fluffy muffins. Add the oil, yogurt, and milk. Mix until well combined.

Add dry ingredientsSift in the flour and baking powder. If using, add a pinch of salt. Stir the mixture gently using a spatula or wooden spoon—just until the dry ingredients are absorbed. Be careful not to overmix, which can make muffins dense.

Fold in chocolate chipsAdd the chocolate chips and gently fold them into the batter. Save a few to sprinkle on top for presentation.

Fill muffin cupsDivide the batter evenly into 10–12 muffin cups, filling each about ¾ full. Top each muffin with extra chocolate chips if desired.

BakeBake in the preheated oven for 20–25 minutes or until golden brown and a toothpick inserted into the center comes out clean or with melted chocolate.

Cool and serveLet the muffins cool in the tin for 5 minutes, then transfer to a wire rack. Serve warm for gooey chocolate centers or allow to cool completely for perfect texture.

Can I use flavored yogurt instead of plain?Yes, vanilla or chocolate yogurt works well—just reduce added sugar slightly.

Can I use whole wheat flour?Yes, substitute half or all of the flour with whole wheat flour for added fiber.

How can I make these muffins dairy-free?Use plant-based yogurt and milk like almond, soy, or oat. They work just as well.

Can I replace sugar with honey or maple syrup?Yes, but reduce the liquid slightly to compensate.

Can I bake these in a mini muffin tin?Absolutely. Just reduce baking time to 12–15 minutes and check for doneness.

How do I prevent muffins from sticking to the pan?Use paper liners or grease well with non-stick spray or butter.

Can I double the recipe?Yes! It doubles perfectly for a larger batch—just use two muffin tins.

How should I store leftovers?Store in an airtight container at room temperature for 2–3 days, or refrigerate for up to 5.

Can I freeze these muffins?Definitely! Wrap tightly in foil or plastic and store in a freezer-safe bag for up to 3 months.

Can I reheat them?Yes, warm them in the microwave for 10–15 seconds or in the oven for 5 minutes at 160°C.
