Preheat the oven to 350º F and line a baking pan with parchment paper. I used a 8 × 8 baking pan.
In a large deep bowl, add all the liquid ingredients and mix well until combined and a liquid, creamy texture is obtained. If the honey is very thick and you have difficulty stirring, use a mixer.
Add all other ingredients (excluding raspberries) to this mixture. Stir again. The mixture should be thick and sticky.
Pour the mixture to the baking pan and level evenly. If you use raspberries, they are distributed on the surface of the mixture and gently pressed. If you use other toppings also now is the time to add them.
Bake the brownies for 20-30 minutes, or until a toothpick inserted in the middle comes out clean. Allow to cool completely before cutting into pieces.
