Easy Blender Brownies (Healthy & Fudgy)
- Total Time: 35 minutes
- Yield: 9 brownies 1x
- Diet: Vegetarian
Description
One-blender healthy brownies that bake up ultra fudgy, rich, and deeply chocolatey with minimal cleanup. Naturally sweetened, made with blended oats and Greek yogurt, and ready in about 35 minutes.
Ingredients
1 cup (90 g) rolled oats (use certified gluten free if needed)
1/2 cup (45 g) unsweetened cocoa powder
1 tsp (4 g) baking powder
1/4 tsp (1.5 g) fine salt
2 large eggs
1/2 cup (120 ml) maple syrup or honey
1/2 cup (120 g) Greek yogurt (plain, preferably full fat)
1 tsp (5 ml) vanilla extract
1/4 cup (45 g) chocolate chips (optional, plus more for topping)
Instructions
1. Heat oven to 350°F (175°C). Line an 8 x 8 inch (20 x 20 cm) pan with parchment and lightly grease if needed.
2. Add rolled oats to a blender and blend until flour-like, about 20 to 40 seconds.
3. Add cocoa powder, baking powder, and salt. Pulse 5 to 10 times to combine.
4. Add eggs, maple syrup (or honey), Greek yogurt, and vanilla. Blend until smooth, scraping down once if needed, 20 to 30 seconds.
5. Stir in chocolate chips if using. Pour batter into the pan and smooth the top. Sprinkle a few extra chips on top if you like.
6. Bake 20 to 25 minutes, until edges are set and the center is just barely firm. A toothpick should come out with moist crumbs, not wet batter.
7. Cool in the pan at least 20 minutes before slicing. For the fudgiest slices, cool completely or chill 30 minutes, then cut.
Notes
Pan size: 8 x 8 inch (20 x 20 cm). For thicker brownies, use a 7 x 7 inch pan and add 3 to 5 minutes bake time.
Do not overbake. Brownies set as they cool. Pull them when the center looks just set.
Egg-free option: Use 2 flax eggs (2 Tbsp ground flaxseed + 5 Tbsp water, rest 5 minutes). Texture will be slightly softer.
Dairy-free option: Use a thick dairy-free yogurt. If batter is very thick, blend in 1 to 2 Tbsp milk.
Storage: Airtight at room temp 2 days or refrigerated up to 5 days. Freeze slices up to 2 months.

About This Recipe
What It Is
A one blender brownie recipe made with blended oats, cocoa powder, Greek yogurt, and natural sweeteners. The texture is classic brownie fudgy and dense, not cakey, with a smooth chocolate finish that tastes indulgent, not wholesome.
Why It Works
Blending the oats into flour creates structure while keeping the crumb tender. Greek yogurt adds moisture and richness without oil overload. Cocoa powder delivers deep chocolate flavor, and baking just until the center is set keeps everything luscious.
When To Make It
Weeknight desserts, meal prep treats, bake sales, lunchbox sweets, or anytime you want brownies fast without turning your kitchen upside down.
Why You Will Love It
- One blender and one pan cleanup
- Naturally sweetened and refined sugar free
- Ultra fudgy texture with shiny brownie tops
- Gluten free with easy dairy free options
- Perfect for beginners and busy bakers
Key Ingredients and Notes
Rolled Oats
Old fashioned rolled oats blend into a smooth oat flour base. This replaces white flour while keeping brownies chewy and satisfying. Use certified gluten free oats if needed.
Unsweetened Cocoa Powder
This is the backbone of flavor. Use high quality cocoa for the richest taste. Dutch process works too but natural cocoa gives a slightly deeper brownie bite.
Greek Yogurt
Adds moisture, protein, and structure. Full fat Greek yogurt yields the fudgiest results. Dairy free yogurt works well too.
Eggs
Eggs provide lift and binding. For egg free brownies, flax eggs work but expect a slightly softer set.
Maple Syrup or Honey
Natural liquid sweeteners blend smoothly and keep the crumb moist. Maple syrup adds a subtle caramel note while honey gives warmth.
Chocolate Chips
Optional but highly encouraged. They melt into pockets of gooey chocolate and elevate these from healthy brownies to bakery worthy brownies.

How To Make Easy Blender Brownies
4
Step 1: Preheat and Prep
Preheat oven to 350°F or 175°C. Line an 8 by 8 inch or 20 by 20 cm pan with parchment paper. Lightly spray if needed.
Step 2: Blend Dry Ingredients
Add rolled oats to a high speed blender. Blend until fine and flour like. Add cocoa powder, baking powder, and salt. Pulse to combine evenly.
Step 3: Add Wet Ingredients
Add eggs, Greek yogurt, maple syrup, and vanilla. Blend until completely smooth. Scrape sides if needed. Batter should be thick but pourable.
Step 4: Fold in Chocolate Chips
Remove blender jar and gently stir in chocolate chips if using. Do not overmix.
Step 5: Bake
Pour batter into prepared pan and smooth top. Bake 20 to 25 minutes. Edges should look set and slightly pulled from the sides while the center looks just barely firm.
Step 6: Cool and Slice
Let brownies cool in the pan for at least 20 minutes. This is essential for clean slices and maximum fudginess.
Pro Tips for Success
- Do not overbake. Brownies continue setting as they cool.
- Blend oats completely to avoid grainy texture.
- Use room temperature ingredients for smoother batter.
- Line the pan with parchment for easy removal.
- For extra glossy tops, let batter rest 5 minutes before baking.
- For thicker brownies, use a smaller pan and add 3 to 5 minutes bake time.
Variations and Substitutions
Dairy Free
Use coconut or almond milk yogurt. Texture stays fudgy and rich.
Egg Free
Use two flax eggs. Mix 2 tablespoons ground flaxseed with 5 tablespoons water and rest 5 minutes.
Extra Protein
Stir in 2 tablespoons chocolate protein powder. Add 1 to 2 tablespoons milk if batter thickens too much.
Peanut Butter Swirl
Drop spoonfuls of natural peanut butter on top and swirl gently before baking.

Storage
Store brownies in an airtight container at room temperature for 2 days or refrigerated for up to 5 days.
Freezing
Freeze individual slices wrapped tightly for up to 2 months. Thaw at room temperature or microwave gently.
Reheating
Warm slices in the microwave for 10 to 15 seconds for gooey centers.
Frequently Asked Questions
Are these brownies really healthy
Yes. They are made with whole grain oats, natural sweeteners, and protein rich yogurt. They are healthier than classic brownies but still taste indulgent.
Do they taste like oat brownies
No. Once blended, the oats disappear into a smooth chocolate crumb. Most people cannot tell they are flourless.
Can I double the recipe
Absolutely. Use a 9 by 13 inch pan and bake 25 to 30 minutes.
Can I make these without a high speed blender
A food processor works well. A standard blender may struggle with oats unless soaked briefly.
Why are my brownies too soft
They likely need more cooling time or were slightly underbaked. They firm up as they set.
