How to make chocolate muffins with blueberries step by step

Step 1 - preparations

• Prepare a muffin baking pan - line it with paper liners (I used tall tulip-style liners) or grease it with butter and dust with flour.
  
• Turn on the oven to 170℃ (fan-forced) or 180℃ (top/bottom heat mode).
• Chop the chocolate.
  100 g chocolate
  

Step 2 - preparing chocolate muffins

• In one bowl, mix together the dry ingredients for the muffins.
  250 g wheat flour - all-purpose, 20 g bitter cocoa, 2 teaspoons baking powder, 200 g sugar
  
• In a second, larger bowl, mix the wet ingredients for the muffins - just stir thoroughly with a spoon or a kitchen whisk.
  360 ml Greek yogurt, 2 eggs, 120 ml oil
  
• Pour the dry ingredients into the wet ingredients and mix with a spoon - the batter will be thick.
  
• Add blueberries and chocolate to the bowl and mix gently.
  approx 200 g blueberries, 100 g chocolate
  
• Spoon the batter into the prepared paper liners or molds - fill them up to a maximum of 2/3 of their height, as the muffins will rise significantly.
  

Step 3 - baking muffins

• Place the muffin pan into the preheated oven and bake for about 25 minutes - until a wooden skewer comes out clean.
• After baking, let the muffins cool slightly and you can serve them still warm :)
