One Bowl Fudgy Brownies in Steps

Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C) and grease your 9×13-inch baking pan. Alternatively, line it with parchment paper for easy removal.
Step 2: Melt the Butter and Chocolate
In a large mixing bowl, combine the butter and chopped semi-sweet chocolate. Place the bowl over a pot of simmering water (double boiler method) or microwave in 30-second intervals until melted and smooth, stirring occasionally.
Step 3: Mix in Sugar and Eggs
Once the chocolate mixture is cool enough, whisk in the sugar until well combined. Add the eggs one at a time, mixing thoroughly after each addition, followed by the vanilla extract.
Step 4: Add Dry Ingredients
Sift in the flour and salt directly into the mixture. Gently fold with a spatula until just combined, being careful not to overmix.
Step 5: Pour and Spread
Pour the brownie batter into the prepared baking pan. Use the spatula to spread it evenly in the pan.
Step 6: Bake
Bake in the preheated oven for about 25 to 30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs (not wet batter).
Step 7: Cool and Cut
Allow the brownies to cool in the pan for at least 15 minutes before lifting them out (if using parchment) and cutting into squares. Enjoy them warm or at room temperature!
Swap Guide

- Butter: Use coconut oil or a plant-based butter substitute for a dairy-free version.
- Semi-sweet chocolate: Dark chocolate can be used for a richer flavor, or you can substitute with dairy-free chocolate for a vegan version.
- Sugar: Coconut sugar or a sugar substitute can be used if you’re looking for a lower glycemic option.
- Flour: Almond flour or a gluten-free all-purpose blend can be used for gluten-free brownies.
Cook’s Notes
- For extra fudginess, do not overbake the brownies; they should still look slightly underdone when you take them out of the oven.
- You can add chocolate chips or nuts to the batter for additional texture and flavor.
- Store leftover brownies in an airtight container at room temperature for up to 5 days.
- For an extra decadent treat, serve warm brownies with a scoop of vanilla ice cream on top.
Refrigerate, Freeze, Reheat
Brownies can be refrigerated in an airtight container for up to a week. If you want to freeze them, cut the brownies into squares and wrap each piece individually in plastic wrap, then place them in a freezer-safe bag. They can be frozen for up to three months. To reheat, simply pop a square in the microwave for about 15-20 seconds until warm.
Helpful Q&A
Can I make these brownies ahead of time?
Absolutely! You can prepare the batter ahead of time and store it in the fridge for up to 24 hours before baking. Just bring it to room temperature before baking.
Can I double this recipe?
Yes! If you want a larger batch, simply double the ingredients and bake in a larger pan. Just be mindful that the baking time may vary slightly.
What can I add to the brownies for extra flavor?
You can add mix-ins like walnuts, pecans, or even swirls of peanut butter or caramel for an extra layer of flavor.
Why are my brownies cakey instead of fudgy?
If your brownies turn out cakey, it may be due to overmixing the batter or baking them for too long. Keep an eye on them and take them out when they still look slightly underdone.
