Preheat the oven to 350°F (180°C) or skip using the air fryer method. Lined up small rectangular glass containers, the mine measures 9 inches x 3.5 inches and has lightly greased parchment. Make sure your oven or air fryer is safe.
In a mixing bowl, whisk Greek yogurt, eggs and peanut butter until smooth.
Whisk the cocoa powder until the mixture matches without showing a mass of cocoa.
Pour the batter into the prepared glass container and bake at 350°F (180°C) for 15-18 minutes. You can also fry at the same temperature for 12-15 minutes until the centered pick is clean.
Let it cool completely in the bread for 10 minutes, then in a rack for an hour to cool for the best texture. Pop in the fridge for an hour for even more nasty texture.
Note 2: The recipe does not contain eggs or did not replace the eggs.
Note 3: Or cocoa powder.
Note 4: Almond butter, cashew butter, and sunflower seed butter can also be used.
Note 5: Sweeteners, granulated or liquid works, such as maple syrup, coconut sugar, or allulose, if sugar-free.
Storage: Store in the fridge in an airtight container for up to 3 days.

Ingredients and alternatives
You will need five ingredients to make these brownies. Here’s how to choose and replace them:

Greek Yogurt – This adds moisture and protein to your brownies, creating a rich texture. It also helps to bond the materials. Other types of yogurt can be used if desired, but do not use the low-fat version. Eggs – Eggs act as binders and add structure to brownies. It also contributes to a damp texture. Unsweetened Cocoa Powder – Cocoa Powder brings a strong chocolate flavor to your brownies. Cocoa powder also works. Peanut Butter – This adds richness, healthy fats and nutty flavor. Almond butter, cashew butter, or sunflower seed butter also works with nut-free options. Hydrating powdered peanut butter reduces calorie count. Granulated Sweeteners – Sweeteners balance the bitterness of cocoa and add sweetness. For the low-carb version, allureose or erythritol is fine. Maple syrup or coconut sugar also works, but it also increases the carb count.

Carine’s tips
Let me share some tips for the perfect brownie.
Adding Chocolate Chips – Adding some sugar-free chocolate chips on top before baking adds a richer chocolate experience. Egg White Options – Replace the entire egg with three egg whites to reduce calorie counts while maintaining structure. Enhanced salt – After baking enhances the chocolate flavor, a pinch of salt is sprinkled on top. Chilled Texture – Store brownies in the fridge before eating for a funny, dense texture. Powdered Peanut Butter – Using rehydrated powdered peanut butter reduces calorie count compared to regular peanut butter. Air Fryer Monitoring – If you use an air fryer, check your brownies frequently to prevent overcooking.
