Mary Berry Double Chocolate Chip Muffins are extra-chocolatey soft muffins made with cocoa powder in the batter and studded with chocolate chips for a rich double-chocolate effect. They rise beautifully with a tender crumb and are made using a simple mix-and-fold method, making them easy for all skill levels.
200g self-raising flour
40g cocoa powder
150g caster sugar
1 tsp baking powder
2 large eggs
125ml milk
100g melted butter (or vegetable oil)
1 tsp vanilla extract
150g chocolate chips (dark, milk, or mixed)
Prepare the tray: Line the muffin tin with paper cases for easy removal.
Combine dry ingredients: Mix flour, cocoa, sugar, and baking powder in a bowl.
Whisk the wet ingredients: Beat eggs, milk, melted butter, and vanilla until smooth.
Fold gently: Add wet ingredients to the dry mixture and fold until just combined.
Add chocolate chips: Stir in most of the chips, keeping a handful for the top.
Fill the cases: Spoon the batter evenly into muffin cups, about two-thirds full.
Top with extra chips: Sprinkle remaining chocolate chips for a bakery-style look.
Bake the muffins: Bake at 180°C (350°F) for 18–20 minutes until risen.
Check doneness: Insert a skewer—it should come out clean or with light crumbs.
Cool on a rack: Allow muffins to cool before storing or frosting (if desired).
