Preheat the oven to 350 degrees and line your 8x8 pan with parchment paper. (You can also apply/coat a thin layer of butter to the pan and dust flour over the same)

Take a bowl and gently whip the eggs in the same. 

Add to the melted butter, the sugar and vanilla extract, and mix well

In a separate bowl, gently mix the dry ingredients (flour, cocoa powder, baking powder, salt)

Add the dry ingredients to the wet mixture and mix well

Now gently fold in 1 1/2 cups of crushed Maltesers

Pour this batter into the 8x8 pan and sprinkle the remaining 1/2 cup of crushed Maltesers to the top

Bake for 30-35 minutes, till the top is crusted and an inserted toothpick when removed, comes out clean.

Serve hot with a dollop of vanilla icecream. Or as is!
