Ingredients for Zero Sugar Brownies with Greek Yogurt
Okay, let’s gather our goodies! The magic of these brownies comes from just a handful of simple ingredients. Here’s what you’ll need:
- 1 cup plain Greek yogurt – Go for full-fat or 2% for the creamiest texture (trust me, it makes all the difference)
- 1 cup unsweetened cocoa powder – Pack it lightly into your measuring cup for that deep chocolate flavor
- 3 large eggs – Room temperature works best for smooth mixing
- 1 teaspoon vanilla extract – The secret flavor booster!
- 3/4 cup zero-calorie granulated sweetener – I use monk fruit blend, but erythritol or stevia work too
- 1/2 teaspoon baking powder – Just enough lift without making them cakey
- Pinch of salt – Balances all the flavors beautifully
- 1/4 cup water or milk (optional) – Only if your batter seems too thick to spread
See? Nothing fancy – just wholesome ingredients that come together to make something truly special. Now let’s get mixing!
How to Make Zero Sugar Brownies with Greek Yogurt

Alright, let’s get baking! These brownies come together so easily – just follow these simple steps and you’ll have fudgy perfection in no time. I’ve made this recipe dozens of times, and these are all my little tricks for getting it just right.
Step 1: Prep the Pan and Oven
First things first – preheat that oven to 350°F (175°C). While it’s heating up, grab your 8×8 inch baking pan and line it with parchment paper. Here’s my secret: leave about 2 inches of overhang on two opposite sides – it’ll make lifting the brownies out SO much easier later. No greasy fingers trying to pry them out!
Step 2: Mix Wet Ingredients
Now for the fun part! In a big mixing bowl, whisk together the Greek yogurt, eggs, and vanilla extract. Keep whisking until it’s completely smooth – no lumps allowed! Then add your zero-calorie sweetener and whisk again until it’s fully dissolved. This step is crucial – you want that sweetener completely incorporated so you don’t get any gritty bits in your finished brownies.
Step 3: Combine Dry Ingredients
Time to bring in the chocolate! Add your cocoa powder, baking powder, and that pinch of salt right into the wet mixture. Now switch to a spatula – gently fold everything together until you’ve got a thick, uniform chocolate batter. If it seems crazy thick (like cookie dough), that’s when you’d add a tablespoon or two of water or milk to loosen it up. But don’t go crazy – we want thick brownies, not cake!
Step 4: Bake and Cool
Pour that gorgeous batter into your prepared pan and smooth the top. Pop it in the oven for 25-30 minutes. Here’s how to know they’re done: the edges will look set, and when you stick a toothpick in the center, it should come out with moist crumbs (not wet batter). Don’t overbake them! Let them cool completely in the pan – I know it’s hard to wait, but this is when they firm up into that perfect fudgy texture. For extra indulgence, try chilling them for an hour before slicing. Oh my goodness, they’re like chocolate fudge then!

Tips for Perfect Zero Sugar Brownies with Greek Yogurt
Here are my tried-and-true secrets for brownie perfection every time:
- Chill for ultimate fudginess – I know it’s tempting, but letting them cool completely (or even refrigerating for an hour) transforms the texture into dense, fudge-like bliss.
- Tweak the sweetness – If your sweetener isn’t quite sweet enough, add an extra tablespoon or two to the batter. Taste as you go!
- Don’t overbake – Pull them out when the center is just set. They’ll keep cooking a bit as they cool.
- Use full-fat yogurt – It gives the richest texture and helps bind everything together beautifully.
Variations for Zero Sugar Brownies with Greek Yogurt
Oh, the fun you can have with these brownies! Try stirring in a handful of chopped walnuts or pecans for crunch. A teaspoon of espresso powder intensifies the chocolate flavor beautifully. For extra indulgence, fold in sugar-free chocolate chips before baking. Need it dairy-free? Swap the Greek yogurt for coconut yogurt and use almond milk instead of regular milk. The possibilities are endless!

Serving and Storing Zero Sugar Brownies with Greek Yogurt
These brownies are perfect cut into 10 generous squares – just enough to satisfy that chocolate craving without going overboard. My favorite way to enjoy them? With a steaming cup of coffee in the afternoon – the bitterness balances the sweetness beautifully. Store leftovers in an airtight container at room temperature for 2 days, or in the fridge for up to 5 days (if they last that long!). Want them warm? Just pop a square in the microwave for 10 seconds – it’s like having freshly baked brownies all over again!

FAQs About Zero Sugar Brownies with Greek Yogurt
I get so many questions about these brownies – here are the ones that pop up most often in my kitchen and inbox!
Can I use flavored Greek yogurt instead of plain?
Oh honey, I tried this once with vanilla yogurt and learned my lesson! Flavored yogurts add extra sugars (even the “light” versions) and can make your brownies too sweet or oddly flavored. Stick with plain – the chocolate does all the talking here!
How can I make these brownies vegan?
Easy peasy! Swap the eggs for flax eggs (1 tbsp ground flax + 3 tbsp water per egg) and use dairy-free yogurt. I’ve had great results with coconut yogurt – just make sure it’s the thick, Greek-style kind.
Why did my brownies turn out cakey instead of fudgy?
This usually means either too much baking powder or overbaking. Remember – we’re going for moist crumbs on the toothpick, not clean! Also, chilling them works wonders for that dense texture we all love.
Can I freeze these brownies?
Absolutely! They freeze beautifully for up to 3 months. I wrap individual squares in parchment, then pop them in a freezer bag. Thaw at room temp or microwave for 15 seconds when the craving hits.
What’s the best zero-calorie sweetener for this recipe?
After testing them all, I swear by monk fruit-erythritol blends – they dissolve best and don’t have that weird cooling aftertaste some others do. But use what you love! Just adjust to your preferred sweetness level.
