Single Serve Brownie in ramekin

Because everybody knows I love to bake, I get asked all the time how I’m not fat.

Portion control, really. I eat one or two (and maybe another) then give the rest away, usually to coworkers and friends.

It also helps I specialize in small batch recipes and recipes for two so I’m only eating a single serve chocolate chip cookie.

But then there are times I want a sweet treat right now and don’t want to fuss with the mess or even have the extra goodies over the weekend.

That’s where making a single serve dessert such as this Single Serve Brownie comes in handy.

It’s a ramekin brownie for one that’s fudgy, rich, and decadent. Everything you want in a brownie without getting stuck with a whole loaf pan of small batch brownies.

It’s very similar to my brownies for two but cut down even further into a single serving brownie so you’re not stuck with temptation.

Unlike my microwave brownie, this one you bake in the oven.

Microwave desserts are great in a pinch, but you don’t get the true essence of an oven-baked fudgy brownie with its ooey gooey chocolate center and slight crisp edges on top.

I served mine with toasted marshmallows on top because I love s’mores, but you can also add a scoop of vanilla bean ice cream or peanut butter whipped cream.

Ramekin For Single Serve Brownie

If you use a different sized ramekin, please note it’ll affect the cook time.

Ingredients For Single Serve Brownie

To make your brownie for one, you’ll need the following ingredients:

  • Semi-sweet chocolate: Helps make your brownie chocolatey and fudgy
  • Butter: Fat needed for the brownie
  • Sugar: Adds sweetness as well as texture
  • Cocoa powder: Use unsweetened natural cocoa powder
  • Egg yolk: Adds richness without adding too much liquid
  • Vanilla extract:Chocolate always tastes better with vanilla.
  • Flour: Brings the batter together.
  • Salt: No bland brownie here! Not needed if using salted butter.

What To Do With Leftover Egg Whites

Because you’re using an egg yolk, you’ll have an extra egg white. Check out my recipes using leftover egg whites.

How To Make A Single Serve Brownie

You don’t need a brownie mix when you can make homemade brownie batter from scratch in minutes! Here’s how to make your ramekin brownie:

  1. Melt butter and chocolate until smooth.
  2. Whisk in sugar, cocoa powder, egg yolk, and vanilla. It may be a little grainy, so make sure you whisk really well.
  3. Stir in flour and salt until incorporated then transfer to your ramekin.
  4. Bake at 350F for 20 minutes or until top no longer looks wet.

Cool for about 15 minutes (so you don’t burn your tongue) then serve immediately as a gooey warm ramekin brownie.

If you love a traditional brownie texture, let it cool completely so the middle firms up, making the perfect single brownie.

This fudgy Single Serve Brownie baked in a ramekin is a rich and decadent brownie for one without being tempted by a whole pan.


  • 1 ounce semisweet chocolate, finely chopped
  • 1 tablespoon unsalted butter, softened
  • 2 tablespoons granulated sugar
  • 1 teaspoon unsweetened cocoa powder
  • 1 large egg yolk, room temperature
  • 1/2 teaspoon vanilla extract
  • 1 tablespoon + 1 + 1/2 teaspoons all purpose flour
  • 1/8 teaspoon table salt
  • 1 tablespoon semisweet chocolate chips or 1 peanut butter cup
  • 2 tablespoons mini marshmallows (optional)


  1. Preheat oven to 350F. Have one 6-ounce ceramic ramekin ready.
  2. In a medium microwave-safe bowl, melt together the butter and chocolate, about 30 seconds. If it's not fully melted after stirring, microwave in 10 second increments.

    Alternately, melt the chocolate and butter together in a saucepan on the stovetop.
  3. Whisk in the sugar and cocoa powder then whisk in egg yolk and vanilla. It'll be a bit grainy so make sure you really whisk it.
  4. Switch to a rubber spatula and gently stir in the flour, salt, and chocolate chips.
  5. Transfer the batter to the ramekin. If adding a peanut butter cup, transfer half of the batter, add the peanut butter cup, then cover with the rest of the batter.
  6. Bake 18-20 minutes or until the top looks baked and the edges are bubbling.
  7. Optional: If adding mini marshmallows, turn on the broiler. Add the mini marshmallows on top then broil until toasted.
  8. Cool 15 minutes then eat for a gooey texture or cool completely for a brownie texture.
