Pro Tips
I’ve made my share of not-so-great brownies over the years. Here are a few hard-won tips to guarantee yours come out perfectly on the first try.
1. Don’t Overmix the Batter.
Once you combine the wet and dry ingredients, mix only until you no longer see streaks of flour. Overmixing develops the gluten in the flour, leading to tough, cakey brownies instead of fudgy ones.
2. Use Runny, Natural Peanut Butter.
The best peanut butter for this has just two ingredients: peanuts and salt. It’s naturally runnier than conventional brands with added sugars and oils, which makes it much easier to dollop and swirl beautifully into the batter.
3. The Swirl Technique Matters.
For those gorgeous swirls, don’t just stir the peanut butter in. Drop spoonfuls of it over the brownie batter, then take a knife and gently drag it through the batter in an “S” pattern, first vertically and then horizontally. Less is more for a defined pattern.
4. Let Them Cool Completely.
This is the hardest part, I know. But letting the brownies cool completely in the pan is essential. It allows them to set, making them fudgier and ensuring you can get clean, perfect slices.
How to Make Healthy Peanut Butter Brownies
Step 1: Preheat your oven to 350°F (175°C). Lightly grease an 8×8 inch baking pan and line it with parchment paper, leaving some overhang on the sides to act as handles.
Step 2: In a medium bowl, whisk together the whole wheat flour, cocoa powder, baking powder, and salt. Set it aside.
Step 3: In another larger bowl, combine the maple syrup, applesauce, eggs, and vanilla extract. Whisk until everything is smooth and well combined.
Step 4: Slowly stream in the melted coconut oil while whisking continuously. This helps it emulsify into the batter properly.
Step 5: Add the dry ingredients to the wet ingredients. Mix with a spatula just until combined. Be careful not to overmix! If you’re using chocolate chips, gently fold them in now.
Step 6: Pour the brownie batter into your prepared pan and spread it evenly with the spatula.
Step 7: Warm the peanut butter in the microwave for 15-20 seconds to make it even more pourable. Drop spoonfuls of the peanut butter over the top of the batter.
Step 8: Take a knife or a skewer and gently drag it through the batter and peanut butter to create a marbled swirl effect. Don’t overdo it.
Step 9: Bake for 22-26 minutes. A toothpick inserted into the center should come out with moist crumbs attached, not wet batter. Be careful not to overbake.
Step 10: Let the brownies cool completely in the pan on a wire rack. This could take a couple of hours. Once cool, use the parchment paper handles to lift them out and cut them into squares.
Substitutions and Variations
This recipe is flexible. Feel free to experiment based on what you have in your pantry.

These brownies are great for planning ahead.
Make Ahead: You can bake the brownies a day in advance. In fact, their flavor and texture often improve after a day. Just keep them covered at room temperature.

Store any leftover brownies in an airtight container.
- At Room Temperature: They will stay fresh for up to 3 days.
- In the Refrigerator: They can last for up to a week. They will be chewier when cold.

Frequently Asked Questions
Q1. My brownies came out dry. What did I do wrong?
Ans: The most common culprit for dry brownies is overbaking. Ovens can vary, so start checking for doneness a few minutes early. You want a toothpick to come out with moist, fudgy crumbs, not completely clean.
Q2. Can I use regular, sweetened peanut butter?
Ans: You can, but it will change the result. Regular peanut butter contains added sugar and oils, which will make the brownies sweeter and potentially a bit greasier. It’s also thicker, making it harder to swirl.
Q3. How do I get those really clean, sharp cuts?
Ans: Patience is key! Let the brownies cool completely. For extra-clean cuts, you can even chill them in the fridge for 30 minutes. Use a large, sharp knife, and wipe it clean with a damp paper towel between each cut.
Q4. Can I double the recipe?
Ans: Absolutely. To double the recipe, use a 9×13 inch baking pan. You will likely need to increase the baking time by 5-10 minutes, so keep a close eye on them.
