Preheat your oven to 350°F (175°C) and line a 9x9-inch pan with parchment paper.My little Olivia always insists on pressing the oven buttons, it’s her “official baker job.”
Whisk the melted [butter] and [granulated sugar], then mix in the [eggs] and [vanilla]. Gently stir in the [cocoa powder], [flour], [salt], and [baking powder]. Fold in [chocolate chips].
Pour the brownie batter into the pan and smooth it out evenly.This is where Olivia sneaks a chocolate chip every single time, quality control, she says.
Beat the softened [butter], [brown sugar], and [granulated sugar] until fluffy. Mix in the [egg] and [vanilla]. Stir in [flour], [baking soda], and [salt], then fold in [chocolate chips].
Drop spoonfuls of cookie dough over the brownie layer and gently press it out.Olivia loves making “cookie dough islands” across the top.
Bake for 30–35 minutes until the edges are set and the center is slightly soft.
Cool completely before slicing into squares.Waiting is the hardest part, we usually count down together.
