Can I add nuts or other mix-ins to the batter?

Yes, you can add nuts or mix-ins like walnuts, pecans, or chocolate chips to the batter before cooking. Stir them in after combining the wet and dry ingredients to distribute them evenly throughout the mixture.

Slow Cooker Brownies Ingredients

• 1 ¼ cups of flour
• ¼ cup of unsweetened cocoa powder
• ¾ tsp of baking powder
• ½ tsp of salt
• ½ cup of butter
• 1 ½ cups + (optional) 1 cup of semisweet chocolate chips
• 1 cup of sugar
• 3 large eggs
• 2 tsp of vanilla extract

How To Make Slow Cooker Brownies

1. Prep Your Cooker: Line your 6-quart slow cooker with a foil collar to protect the brownies’ edges. Just fold aluminum foil into a thick strip and place it around the cooker’s interior. Spray the inside with nonstick spray, then place parchment paper at the bottom, within the foil.
2. Whisk Dry Ingredients: In a small bowl, combine the flour, cocoa powder, baking powder, and salt. Set this mixture aside for later.
3. Melt Butter and Chocolate: In a microwave-safe bowl, add the butter and 1 ½ cups of chocolate chips. Microwave in 30-second intervals, stirring after each until completely melted and smooth.
4. Sweeten the Mix: To the melted chocolate, stir in the sugar until fully incorporated.
5. Add Eggs and Vanilla: Mix in the eggs and vanilla extract, ensuring the mixture is smooth and well combined.
6. Combine Dry with Wet: Gently fold in the dry ingredients to the chocolate mix. Add the additional cup of chocolate chips if desired. Stir just until the batter comes together; avoid overmixing.
7. Cook on Low: Transfer the batter into the prepared slow cooker. Cover and cook on low for 3 hours.
8. Cool and Serve: After cooking, turn off the slow cooker and uncover. Let the brownies cool in the cooker for 1 hour. Then, lift out, let set completely, cut into bars, and serve.

How do I know when the brownies are done?

The brownies are done when the edges begin to pull away slightly from the sides of the slow cooker, and a toothpick inserted into the center comes out with a few moist crumbs attached. The surface should look set and not liquid.

Recipe Tips

• Check the Brownies Early: I always peek at my brownies around the 2.5-hour mark. Your slow cooker might run hotter than you think, and nobody wants overdone brownies.
• Foil Collar Trick: A snug foil collar prevents the edges from cooking too fast, ensuring even baking without dry or burnt edges.
• Prep in Advance: Mix your dry ingredients the night before to save time and streamline your baking process the next day.

Recipe Variations

• Nutty Delight: Stir in a cup of chopped walnuts or pecans to the batter before cooking for a crunchy texture.
• Mint Chocolate Twist: Add a teaspoon of peppermint extract to the batter for a refreshing mint chocolate flavor.
• Double Chocolate Indulgence: Swap out half the semisweet chocolate chips for white chocolate chips for a dual-chocolate experience.
• Coffee-Infused: Mix in a tablespoon of instant espresso powder to enhance the chocolate flavor and add a subtle coffee note.
• Salted Caramel: Drizzle caramel sauce over the batter before cooking and sprinkle with sea salt for a sweet and salty treat.

What To Serve With Brownies

You can enjoy serving your delicious brownies with a variety of options including something like a vanilla ice cream or chocolate syrup, they will go well with the texture and flavor of it.

You may also consider serving your brownies with fresh berries, mint leaves, or even a cup of warm coffee the way I love especially when the coffee is without sugar.

How To Store Brownies

In The Fridge:

Store brownies in an airtight container with parchment paper between layers to prevent them from sticking and they will last for up to 5 days when refrigerated. Just make sure the container is sealed tightly to keep them moist and fresh. Avoid storing near strong-smelling foods to maintain their chocolatey scent.

In The Freezer:

Brownies can be frozen for up to 3 months, all you need to do is wrap them individually in plastic wrap, then place them in a zip-lock bag. Thaw at room temperature for a few hours before enjoying. This method helps preserve their texture and taste.

How To Reheat Brownies

Reheat your Brownies by placing them on a microwave-safe plate and microwave them for 20-30 seconds until warm. Or, warm them in an oven at 350°F for 5 minutes for a crispy edge. Enjoy them slightly warm for a gooey, chocolatey experience.
