Making the Slow Cooker Chocolate Lava Brownie Pudding is simple if you follow these easy steps:

1. Prepare the Slow Cooker: Grease the inside of your slow cooker with cooking spray or butter to prevent sticking.
2. Mix Dry Ingredients: In a large bowl, whisk together the flour, sugar, cocoa powder, baking powder, and salt until well combined.
3. Add Wet Ingredients: Pour in the melted butter and milk. Stir until the batter is smooth and free of lumps.
4. Transfer to Slow Cooker: Pour the batter into the prepared slow cooker, spreading it evenly.
5. Cook: Cover and cook on low for 2-3 hours. The edges should be firm, while the center remains soft and gooey.
6. Check for Doneness: You can test for doneness by gently inserting a toothpick into the edges; it should come out clean, while the center will remain slightly undercooked.
7. Serve: Once it’s done, turn off the slow cooker and let it sit for a few minutes before serving.
