Ingredients & Prep for Sweet Potato Protein Brownies
These brownies are incredibly simple — just a few wholesome ingredients that come together in one bowl. Each element brings something special: the sweet potato for natural sweetness and fiber, the protein powder for structure and richness, and the nut butter for that irresistibly fudgy bite.
Ingredients
- 1 cup (240g) mashed sweet potato – roasted or steamed until tender, then mashed smooth
- ½ cup (120g) nut butter – peanut, almond, or cashew all work beautifully
- ½ cup (50–60g) chocolate protein powder – whey or plant-based, depending on preference
- Optional Add-Ins:
- 2 tbsp cocoa powder for extra chocolate depth
- 2 tbsp maple syrup or honey for extra sweetness
- A handful of dark chocolate chips or crushed nuts for texture
Pro Tip: Use your Escali Primo Digital Food Scale to measure precisely — it’s compact, accurate, and keeps your portions consistent.

- Mixing Bowl – large enough for easy stirring

Prep Steps
- Preheat your oven to 350°F (175°C). Line a 9×9-inch baking pan with parchment paper or lightly grease it with your Lightyear Silicone Pastry Brush for easy cleanup.
- Mash the sweet potato until completely smooth — you can use a fork or hand mixer. The smoother, the fudgier your brownies will be.
- Combine all ingredients in a large mixing bowl. Stir until fully blended using your NileHome Whisk Set, then switch to a spatula to fold everything together.
- Spread the batter evenly into your prepared pan. It should be thick but spreadable.
- Bake for 18–22 minutes, or until the center is set but still slightly soft to the touch.
- Cool completely before slicing — this helps them firm up into that perfect, chewy texture.
💡 Sophie’s Tip: Want extra flavor layers? Swirl in a spoonful of almond butter before baking, or sprinkle crushed walnuts on top. You’ll get that bakery-style finish with no added fuss.
Step-by-Step Instructions for Sweet Potato Protein Brownies
These fudgy, high-protein brownies come together in minutes — no fancy equipment or complex steps needed. Follow these simple instructions to bake your next favorite healthy dessert.
1. Preheat and Prepare Your Pan
Set your oven to 350°F (175°C). Line an 8×8 or 9×9-inch pan with parchment paper or lightly grease it using your Lightyear Silicone Pastry Brush Set. This ensures an easy release and a clean cut once your brownies are baked.
2. Mash the Sweet Potato
If you haven’t already, roast or steam your sweet potatoes until fork-tender. Mash them thoroughly using a fork, potato masher, or the NileHome Stainless Steel Whisk Set until smooth and lump-free. The smoother the mash, the creamier your final texture.
3. Combine Wet and Dry Ingredients
In a large mixing bowl, combine the mashed sweet potato, nut butter, and chocolate protein powder. Stir gently with a spatula until you get a thick, cohesive batter. For extra flavor, you can mix in cocoa powder or a drizzle of honey.
If you like a little crunch, fold in chopped nuts or dark chocolate chips at this stage.
4. Pour and Smooth the Batter
Transfer the mixture into your prepared pan. Use a spatula to spread it evenly across the surface, pressing down slightly to remove air pockets. For perfect layers, weigh your ingredients using the Escali Primo Digital Food Scale to ensure balance in every batch.
5. Bake to Fudgy Perfection
Place the pan in the center of your oven and bake for 18–22 minutes. You’ll know they’re done when the edges are set and a toothpick inserted in the center comes out mostly clean with a few moist crumbs. Avoid overbaking — they’ll firm up as they cool.
6. Cool Completely Before Cutting
Set the pan on a cooling rack and let the brownies rest for at least 20–30 minutes before slicing. This allows them to set into that perfectly chewy, fudgy consistency everyone loves.
7. Slice and Enjoy
Cut into 9–12 even squares using a sharp knife (a Mercer Culinary Millennia 10-Inch Bread Knife works beautifully for clean edges). Store leftovers in an airtight container at room temperature for up to 2 days, or refrigerate for up to a week.
💬 Sophie’s Baking Note:
If you want a slightly gooier texture, pull them out right at 18 minutes. For a cake-like finish, give them closer to 22–24 minutes. A sprinkle of sea salt on top before baking adds a gourmet touch without any extra effort.
For another easy chocolate fix, try our One-Bowl Greek Yogurt Brownies — they’re another reader favorite for fudgy flavor with a healthy twist.

Why These Brownies Are a Smart Snack Choice
1. Sweet Potatoes: The Natural Performance Fuel
Sweet potatoes are rich in complex carbohydrates, vitamin A, and potassium — a trio that supports energy production and post-workout recovery. Their natural sweetness also eliminates the need for refined sugar, keeping your blood sugar stable while curbing cravings.
2. Protein Powder: Building & Repairing Muscles
Adding protein powder turns this dessert into a performance-friendly snack. Protein is essential for muscle repair and growth after workouts, and consuming a balanced protein-carb combo (like these brownies) helps replenish glycogen stores efficiently (Harvard Health, 2023).
3. Nut Butter: Healthy Fats for Satiety
Whether you use peanut, almond, or cashew butter, these fats promote fullness and add a creamy texture that makes the brownies rich and satisfying. Nut butters also bring a subtle sweetness and enhance the chocolate flavor naturally.
4. Balanced Macros for Energy & Satisfaction
Each brownie contains a mix of carbs, protein, and healthy fats — ideal for fueling an afternoon workout or preventing that 3 PM slump. Pair one with a cup of coffee or a glass of milk for a quick, nutritious pick-me-up.
💡 Sophie’s Nutrition Tip:
For a meal-prep boost, make a double batch and freeze individual squares. Reheat one in the microwave for 20 seconds for that freshly baked texture anytime you want something warm and comforting.

FAQs About Sweet Potato Protein Brownies
Q1. Can I use canned sweet potato puree instead of fresh?
Yes! Just make sure it’s 100% pure sweet potato with no added sugar or fillers. Canned puree works perfectly for a quicker prep and gives a similar fudgy texture.
Q2. What protein powder works best in this recipe?
A chocolate-flavored whey or plant-based protein powder is ideal. Each brand varies slightly in texture, so if your batter feels too thick, add 1–2 tablespoons of milk or almond milk to smooth it out.
Q3. Can I make these brownies vegan?
Absolutely. Choose a plant-based protein powder and nut butter, and skip honey if you’re using it as a sweetener. The rest of the recipe is naturally dairy- and egg-free.
Q4. How can I make them even more chocolatey?
Add 2 tablespoons of unsweetened cocoa powder and fold in a handful of dark chocolate chips before baking. The result is a deeper, richer chocolate flavor without needing extra sugar.
