Why you’ll love this recipe
Flavor and texture: These brownies bake up moist, soft, fudgy, and chewy.
Small ingredient list: You only need eight ingredients, which are all pantry staples.
One bowl: No need to dirty a bunch of dishes, this batter comes together in one mixing bowl.
Two pan sizes: Choose from a 9×5 loaf pan or a muffin pan.
*Full recipe is below in the recipe card.*
- Add butter, chocolate chips, and sugar to a microwave safe bowl and microwave until the butter and chocolate is melted.
- Whisk in egg, water, and vanilla.
- Whisk in cocoa powder, flour, powdered sugar, and salt.
- Stir in chocolate chips.
- Pour batter into a greased 9×5 loaf pan or 6 standard muffin-cups. Bake!
- Do not overbake. These brownies should be removed from the oven when they are dry on top and as soon as a toothpick inserted into the center comes out without thin raw batter on it (moist/fudgy/melted chocolate is ok).
- Don’t skip the chocolate chips! The chocolate chips help to make these brownies super chocolaty. Use semisweet, milk chocolate, or dark chocolate chips. Note that the sweetness of the brownies will vary based on how sweet your chocolate chips are.
- These brownies are best served slightly warm. Allow them to cool down before slicing and removing from the pan.
Pan sizes and bake times
9×5 Loaf pan: If using a loaf pan be sure it is 9×5. A larger loaf pan will produce brownies that are quite thin. If your loaf pan is a bit smaller you will likely need to add a few minutes to the bake time. My 9×5 pan is glass, if yours is metal you will likely need to add a few minutes to the bake time.
Standard muffin pan: This batter is enough to fill six standard sized muffin cups. Be sure to grease them well.
Bake time for the loaf pan will be longer than the muffin pan. Don’t have either of those pans? Ty our Homemade Brownies (in an 8×8) or our Brownie in a Mug.
Serving and storage
Serve brownies warm alongside a glass of milk or with ice cream.
Store tightly covered at room temperature for up to 3 days or freeze for up to 3 months.

Small Batch Brownies
- 4 tablespoons unsalted butter, cut into pieces
- ½ cup plus 2 tablespoons chocolate chips*, divided
- ½ cup granulated sugar
- 1 large egg
- 2 tablespoons water
- ¾ teaspoon pure vanilla extract
- generous ¼ cup unsweetened cocoa powder
- ½ cup all purpose flour**
- ¼ cup powdered sugar
- couple pinches salt
- Preheat oven to 350°F. Line a 9×5 loaf pan with foil or parchment paper leaving a couple inches overhang, grease the foil/parchment. OR grease the cavities of a 6-count standard sized muffin pan.
- Place the butter, 2-tablespoons chocolate chips, and sugar in a medium-sized microwave safe bowl. Microwave in 20 seconds increments, stirring well in between, until the butter and chocolate are melted. Allow the mixture to cool down for a couple minutes.
- Add the egg, water, and vanilla and whisk for one whole minute. Add the cocoa, flour, powdered sugar, and salt and whisk until combined. Tap all of the excess batter off the whisk and remove it from the bowl. Stir in the chocolate chips with a rubber spatula or wooden spoon.
- Spread the batter into the prepared loaf pan or divide between 6 muffin cups. Bake the loaf pan for 25-30 minutes and the muffin pan for 15-20, until a toothpick inserted just outside the center comes out with moist fudgy crumbs but no thin raw batter (see note on bake time***).
- Place the pan on a wire rack to cool. We like these best served warm. They will firm up as they cool.
