Here's how to make chocolate brownie without an oven at home.

Prepare the Batter, in a bowl, mix flour, cocoa powder, baking powder, baking soda, salt, and sugar. add melted butter, vanilla extract, and milk, then mix until smooth.

Grease the Pan, take a deep pan or a pressure cooker and grease a small baking tin or steel plate with butter. line it with parchment paper.

Place a thick-bottomed pan or pressure cooker on low heat. add a layer of salt or sand at the bottom and preheat for 5 minutes with the lid on without the whistle if using a cooker.

Pour the Batter, transfer the batter to the greased pan and tap gently to remove air bubbles.

Cook on Low Heat, place the pan inside the preheated pot, cover it with a lid, and cook for 30–40 minutes on low heat.

Check for Doneness, insert a toothpick in the center; if it comes out clean or with slight crumbs, your brownie is ready.

Cool and Serve, let it cool completely before cutting it into squares. enjoy your soft and fudgy homemade brownie without an oven.
