Wholesome Ingredients for This Healthy Peanut Butter Brownies Recipe

Let’s take a closer look at some of the nutritious ingredients that make these easy baked brownies with peanut butter so special:

Banana: A ripe banana not only adds natural sweetness but also works as a binder, reducing the need for extra fat. For substitutions, try mashed avocado or canned pumpkin.
Peanut Butter: A rich source of healthy fats and protein. Choose an all-natural peanut butter with no added sugar. Almond butter is a great alternative if you prefer a different flavor or need to avoid peanuts.
Cocoa Powder: Unsweetened cocoa powder provides antioxidants and a deep chocolate flavor without extra sugar. Opt for dark, high-quality cocoa for the best flavor and health benefits.
Whole Wheat Flour & Ground Grain Flour: These flours add fiber and nutrients while keeping the texture moist and tender. To make it gluten-free, use a 1:1 gluten-free baking flour or oat flour.

Preheat your oven to 350°F (180°C). Line an 8×8-inch baking pan with parchment paper for easy removal.

How to Customize These Healthy Peanut Butter Brownies for Your Diet

Vegan: Swap the Greek yogurt for a plant-based yogurt and replace the egg with a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water).

Keto-Friendly: Replace maple syrup with a keto-approved sweetener like erythritol or stevia, and use almond flour instead of whole wheat flour.
Nut-Free: Substitute sunflower seed butter for peanut or almond butter, ensuring it’s free of added sugars.
