This Single Serve Brownie recipe is a super small batch recipe that is mixed up in one bowl (no mixer needed) and makes two small fudgy brownies that you can either have both yourself or share one.
This 1-2 serving, small batch brownie recipe is the perfect solution for when you're craving a fudgy brownie, but you don't have the time to make an entire batch OR you don't want lots of brownies leftover. Baking them in a muffin pan gives the perfect balance of a chewy edge with fudgy center.

⭐Why I Love It:
- Super Small Batch Recipe - I love that this single serve brownie recipe makes only two small brownies so I can satisfy my chocolate craving without having to make an entire pan of brownies. Another favorite way to satisfy a sweet tooth is with a microwave mug cake recipe like this Nutella Mug Cake or Molten Chocolate Mug Cake. Or for a small batch cookie, try this Single Serve Double Chocolate Cookie!
- No Mixer Needed - Because it's such a small amount of batter, you can mix it all up by hand using a whisk and rubber spatula instead of needing to use an electric or stand mixer.
- Fudgy Center - By using an egg yolk and by not over baking the brownie, the center is perfectly rich fudgy. For a full batch recipe, try this Fudgy Brownie Recipe!
🥘Ingredients
- Unsalted Butter - If you use salted butter, just add about half the salt. When measuring the butter, I prefer to cut from the middle of the stick since the tablespoon markers at the ends of the stick can be off. For a small recipe, it's extra important to be accurate with measurements.
- Brown Sugar - When measuring brown sugar, you want to pack it into the measuring cup. I used light brown sugar, but you can use dark brown sugar as well. If you don't have brown sugar, I also have a full batch recipe for Chocolate Chip Cookies without Brown Sugar.
- Egg Yolk - Using only the egg yolk helps keep the recipe super small and it also helps give the the brownie its fudgy center. You can use the leftover egg white to make this Single Serve Vanilla Cupcake or Single Serve Chocolate Cupcake recipe!
- Vanilla Extract - For flavor!
- Cocoa Powder - A key ingredient for this recipe! If you don't have cocoa powder, I love this full batch recipe for brownies with hot chocolate mix.
- All-Purpose Flour - You only use a small amount of flour for this recipe to keep them extra fudgy. When measuring flour, make sure to use the 'spoon and level' method. This is where you spoon the flour into the measuring cup or spoon and then level off the top. Instead of dipping the measuring cup directly into the flour bin which can lead to over measuring.
- Kosher Salt - I like the Diamond Kosher Salt. A small amount of salt is so important to balance the sweetness.
- Chocolate Chips - These are optional, but I like the extra boost of melty chocolate.

💭Recipe Tips
- Don't Over Bake - The key to having fudgy brownies is to not over bake them. A toothpick inserted in the center should come out with fudgy/moist brownie crumbs and not wet batter.
- Use 'Spoon and Level' Method When Measuring Flour - When measuring flour, make sure to use the 'spoon and level' method. This is where you spoon the flour into the measuring cup and then level off the top. Instead of dipping the measuring cup directly into the flour bin which can lead to over measuring.
👩🍳Recipe FAQs
Using only the egg yolk helps keep the brownie recipe super small and it also gives a fudge center.
The spoon and level method is best for measuring flour because it reduces the risk of over measuring. Start by fluffing up the flour int the container then use a spoon to spoon it into the measuring cup and use a knife to level off the top. This is much more accurate than scooping the flour directly from the container with the measuring cup.
