Line an 8X8 pan with parchment paper and preheat oven to 350F
In a large bowl combine cooled melted butter and granulated sugar. Mix using a non-stick spatula
Add in eggs, lemon juice, and lemon zest
Mix again until homogenous
Add in salt and flour and mix until just combined
Pour batter (it will be thick!) into the prepared pan and spread into an even layer
Place raspberries on top of the batter and gently press them into the dough
Bake for 20 minutes until edges are set. A toothpick should come out clean from the center of the dough
Let rest while you make the glaze
In a small bowl combine glaze ingredients. Mix until the glaze is smooth and the desired consistency. If you would like a thicker glaze, use less lemon juice! If you prefer a thinner glaze, add in more lemon juice!
Pour glaze on top of cooled brownies. Let glaze set for at least 20 minutes. Slice and enjoy!
