Prepare 3 separate bowls.
First bowl: whisk 100g unsalted butter with 70g sugar.
Second bowl: Add 50ml semi-skimmed milk with 3 tbsp double cream and stir thoroughly.
Third bowl: Beat 2 eggs to combine the yolks and whites.
Add the third bowl into the first bowl (several times) and whisk.
Sift 200g cake flour, 2 tsp matcha powder, and 1.5 tsp baking powder on top of the batter (from Step 2) and mix gently.
Add the milky cream mixture (second bowl from Step 1) onto the batter.
Cut 100g dark chocolate into 18-20 squares.
Grease your muffin pan with olive oil.
Divide your batter into 9 portions.
For each portion, add the batter onto the muffin cup three times, each time it should be filled with 3-5 chocolate squares (i.e. 3 layers of chocolate squares).
Bake your muffin batter in an oven preheated to 180 °C for 30 minutes.
