Bakery-style blueberry chocolate chip muffins

Ingredients

• 2 eggs
• Fresh blueberries
• 150 g chocolate chips
• 115 g unsalted butter, melted
• 200 g granulated sugar
• 2 tsp baking powder
• 1/2 tsp baking soda
• 100 g Greek yogurt
• 2 tbsp neutral oil
• 1 tbsp vanilla extract
• 315 g all-purpose flour
• 250 ml milk + 1 tbsp vinegar, rested 10 minutes (homemade buttermilk)
• Kit Kat or chocolate chunks, to decorate
• Optional filling: whipped cream with sugar, or cream cheese with powdered sugar

Instructions

1. Mix the melted butter with the sugar, then beat in the eggs until lump-free.
2. Add the oil, yogurt and vanilla, then pour in the homemade buttermilk.
3. In a separate bowl, combine the flour, baking powder, baking soda and salt, and fold in the blueberries.
4. Pour the dry mix into the wet ingredients and stir until just combined — do not overmix.
5. Divide evenly between muffin cups and top with chocolate chunks.
6. Bake 5 minutes at 220°C (425°F), then lower to 190°C (375°F) for 15–20 minutes, until a toothpick comes out clean.
