Ingredients You’ll Need
Let’s break down the simple ingredients that make these blondies both delicious and nourishing:
- ½ cup peanut butter – Use a natural, creamy peanut butter for a rich flavor and healthy fats.
- ⅓ cup Greek yogurt – Adds moisture and protein without the need for extra oil or butter.
- ¼ cup honey or maple syrup – Natural sweeteners that keep things just sweet enough.
- 1 egg – Helps bind everything together while adding structure and richness.
- 1 teaspoon vanilla extract – Adds warmth and enhances the natural sweetness.
- 1 cup oat flour – A wholesome, fiber-rich alternative to all-purpose flour.
- ½ teaspoon baking soda – Lifts the blondies for a light, soft texture.
- ¼ teaspoon cinnamon – A subtle touch of spice for extra flavor depth.
- ¼ cup mini chocolate chips (optional) – Because a little chocolate makes everything better.
Pro Tip: You can make your own oat flour by blending rolled oats in a high-speed blender until fine.
Step-by-Step Directions
1. Preheat and Prep
Preheat your oven to 350°F (175°C). Line a small baking pan (8×8 inches works great) with parchment paper or lightly grease it to prevent sticking.
2. Mix the Wet Ingredients
In a large mixing bowl, whisk together the peanut butter, Greek yogurt, honey (or maple syrup), egg, and vanilla extract. Stir until the mixture is smooth and well combined.
3. Add the Dry Ingredients
To the same bowl, add in the oat flour, baking soda, and cinnamon. Stir everything together until a thick batter forms. It should be smooth but not runny.
4. Fold in Extras
If you’re adding mini chocolate chips, chopped nuts, or dried fruit, gently fold them into the batter.
5. Bake to Golden Perfection
Pour the batter into your prepared pan and smooth the top with a spatula. Bake for 20–23 minutes, or until the top is golden and a toothpick inserted in the center comes out clean.
6. Cool and Slice
Let the blondies cool completely in the pan before slicing them into squares. This helps them set properly and makes slicing easier.
Tips for the Best Healthy Breakfast Blondies
- Don’t overbake. The blondies will continue to cook slightly as they cool. For extra chewy bars, aim for 20 minutes.
- Cool completely. This helps the structure firm up. Warm blondies may crumble when sliced.
- Use full-fat Greek yogurt. It adds richness and moisture that low-fat versions can lack.
- For extra protein, mix in a tablespoon of your favorite vanilla protein powder.
- Make it vegan. Substitute the egg with a flax egg and use maple syrup instead of honey.
Make-Ahead and Storage Tips
One of the best things about these peanut butter breakfast blondies is how well they store. Here’s how to keep them fresh:
- In the fridge: Store in an airtight container for up to 5 days.
- In the freezer: Wrap individual blondies in parchment paper and store in a freezer-safe bag for up to 3 months. Defrost in the fridge overnight or microwave for 15–20 seconds for a quick breakfast on the go.
Customizations and Variations
Want to make these your own? Here are a few fun ways to switch up the flavor or nutritional profile:
- Swap peanut butter for almond or cashew butter for a different nutty flavor.
- Add fruit: Fold in chopped bananas or blueberries before baking.
- Make it spiced: Add pumpkin spice or chai spice instead of just cinnamon.
- Add crunch: Sprinkle the top with crushed nuts or coconut flakes before baking.
Serving Suggestions
While these are designed as a grab-and-go breakfast, they can also be served in other fun ways:
- Topped with Greek yogurt and fresh berries for a brunch-worthy plate
- Drizzled with a little extra peanut butter and a few banana slices
- Paired with your morning coffee or a smoothie for a balanced start
- Warmed and served as dessert with a scoop of vanilla frozen yogurt or coconut whip

Frequently Asked Questions

Is this recipe gluten-free?
Absolutely—as long as you use certified gluten-free oats to make your oat flour.
What’s the best pan size for this recipe?
An 8×8-inch square pan is ideal, but a small rectangular loaf pan or even muffin tins can work. Just adjust baking time accordingly.
Can I make this without an egg?
Yes! Substitute with a flax egg (1 tablespoon ground flaxseed + 3 tablespoons water, let sit 5 minutes).
