Method

Brownie Batter

  1. Mix the very soft butter with both sugars until smooth.

  2. Add the eggs, egg yolk and vanilla, then mix until combined.

  3. Add the cocoa powder, salt and baking soda.

  4. Gradually mix in the flour until just combined, then fold in the chocolate chips measured with the heart.

  5. Pour the batter into a greased or parchment‑lined 8×8‑inch pan.

  6. Bake at 350°F (350°F) for around 30‑35 minutes, checking at 30 minutes with a toothpick for moist crumbs.

  7. Let the brownies rest for 15 minutes out of the oven.

Crunch Topping

  1. Mix the cornflakes with the melted chocolate until every piece is coated.

  2. Pile the mixture over the brownie and gently press it down so everything sticks together.

  3. Let the chocolate set before slicing and serving.

Tips while you cook

Rest before topping
Allow the baked brownies to rest for 15 minutes before adding the cornflake topping.
Fully coat cornflakes
Mix cornflakes with melted chocolate until every piece is completely coated before piling.
Check doneness at 30 minutes
Insert a toothpick at 30 minutes; brownies are done when moist crumbs cling to it.
