Ingredients You’ll Need

250g plain flour
50g cocoa powder (unsweetened)
150g caster sugar
2 teaspoons baking powder
½ teaspoon bicarbonate of soda
¼ teaspoon fine sea salt
2 medium eggs, at room temperature
120ml vegetable oil (or melted unsalted butter)
200ml plain yoghurt or buttermilk
1 teaspoon vanilla extract
200g dark chocolate chips (or a mix of dark and milk)

Tip: For an extra fudgy texture, chop half the chocolate chips into smaller pieces so they melt into the batter rather than staying whole.

How to Make Double Chocolate Chip Muffins

Preheat the oven to 200°C (180°C fan). Line a 12-hole muffin tin with paper cases — this drastically cuts down on washing up later.
Whisk the dry ingredients in a large mixing bowl: flour, cocoa powder, sugar, baking powder, bicarbonate of soda, and salt. Stir until the cocoa has evenly coloured the flour a deep, uniform brown — you shouldn’t see any pale streaks.
Combine the wet ingredients in a separate jug (or just make a well in the centre of the dry bowl if you want to save another dish). Whisk together the eggs, oil, yoghurt, and vanilla until the mixture looks smooth and glossy, like a thin milkshake.
Pour the wet into the dry and stir gently with a spatula. Stop mixing the moment you see no more pockets of dry flour — the batter will look lumpy and slightly thick, which is exactly what you want. Overmixing makes tough muffins.
Fold in the chocolate chips with just a few turns of the spatula. You’ll hear the chips scraping against the bowl as they distribute through the batter.
Divide the batter evenly among the 12 cases. Use two spoons or a spring-loaded scoop — the cases should be almost full to the brim, about three-quarters full. The batter will feel quite stiff and sticky.
Bake for 16-18 minutes. At the 15-minute mark, your kitchen will smell intensely of chocolate and the tops will look domed and cracked. Insert a skewer into the centre of one muffin — it should come out with a few moist crumbs attached, not wet batter. The tops should spring back when lightly pressed with your finger.
Cool in the tin for 5 minutes, then transfer the muffins to a wire rack. You’ll hear a slight sizzle as they release from the paper cases. Let them cool completely before storing, but I won’t judge if you eat one warm.

Tips From My Kitchen

Measure your flour correctly: Spoon it into the measuring cup and level it off with a knife. Scooping directly from the bag packs the flour down and gives you too much, making the muffins dry and dense. I’ve ruined many batches by being careless here.
Use room-temperature eggs: Cold eggs seize the fat in the yoghurt and oil, creating a batter that’s stiff and hard to mix. Leave them on the counter for 20 minutes, or place them in a bowl of warm water for 5 minutes before you start.
Don’t overmix the batter: Stir until the flour just disappears. A few lumps are fine — they’ll disappear during baking. Overmixing develops gluten, and that gives you rubbery, tough muffins instead of soft, tender ones.
Resist opening the oven door early: The first 12 minutes are critical for the rise. Peeking lets cold air rush in and collapses the domed tops. Trust the process and wait until the timer goes off.
Freeze for later: These muffins freeze beautifully. Cool them completely, then pop them in a zip-top bag. To reheat, microwave one for 20 seconds or warm it in a low oven for 5 minutes. My husband, who’s usually picky, asked for seconds straight from the freezer — he couldn’t wait for them to thaw.

Common Mistakes to Avoid

Overcrowding the pan: If you have a 6-hole tin and the recipe makes 12, don’t try to cram all the batter into one tray. The muffins need space to rise and dome. Bake in two batches, or use two tins if you have them. The first batch will be done while the second one bakes.
Wrong temperature: Baking at too low a temperature results in flat, pale muffins that spread sideways instead of rising up. Always preheat fully to 200°C (180°C fan). If your oven runs hot, use an oven thermometer to double-check — it’s a small investment that saves many baking disasters.
Skipping the rest time: Letting the batter rest for 10 minutes before baking allows the starch to absorb the liquid, which gives you a taller, more tender muffin. It’s a simple step that makes a noticeable difference in texture.

What to Serve With Double Chocolate Chip Muffins

Frequently Asked Questions

Can I use milk chocolate instead of dark chocolate?

Absolutely, though the muffins will be noticeably sweeter. I often use a mix of half dark and half milk chocolate chips to balance the richness of the cocoa. If you only have a white chocolate bar, chop it into chunks — it melts into sweet pockets throughout the batter.

Can I make these gluten-free?

Yes, you can substitute the plain flour with a good quality gluten-free plain flour blend that contains xanthan gum. The texture will be slightly more delicate, so handle the batter gently and don’t overmix. I’ve had success with this swap several times for friends with dietary needs.

How do I store leftover muffins?

Keep them in an airtight container at room temperature for up to three days. If you live in a humid climate, line the container with a paper towel to absorb excess moisture. For longer storage, freeze them in a sealed bag for up to three months.

Why did my muffins turn out dry?

This usually happens from overmixing the batter or overbaking. Check your oven temperature with a thermometer next time, and pull the muffins out the moment a skewer comes out with just a few moist crumbs. Also, make sure you’re using full-fat yoghurt, not low-fat, as the fat keeps them tender.

Can I add nuts or other mix-ins?

Certainly. Fold in up to 100g of chopped walnuts, pecans, or even dried cherries along with the chocolate chips. For a different twist, swirl in a tablespoon of peanut butter before baking — it creates lovely marbled pockets.
