Super easy and ridiculously delicious Vegan Blondies ready in 30 minutes! These blondies use chia seeds instead of eggs and olive oil instead of butter—and you won’t miss the dairy or eggs.

Despite being indulgent and kid-friendly, these blondies are higher in fiber and packed with nutritious ingredients. They disappeared in minutes when I brought a batch to a gathering of teens—everyone loved them.
These blondies work great as a dessert or as an unexpected high-fiber snack for kids. They are safe for households with egg and dairy allergies when you use dairy-free chocolate chips. Because the recipe uses olive oil instead of vegan butter, it can also be soy-free if you choose soy-free chocolate chips.
😍 Why You’ll Love This Recipe
These vegan blondies are simple to make, use common pantry ingredients, and are a hit with kids and adults.
- Easy: If you can measure and mix, you can make these. All ingredients are used at room temperature—no melting or lengthy prep required.
- Simple ingredients: Everything is available in most grocery stores and likely already in your pantry.
- Kid-approved: Perfect for school events, parties, or family snacks—kids loved them at my recent gathering.
- Allergy-friendly: Egg-free, dairy-free, and can be made soy-free depending on your chosen chocolate chips.
- Chia “egg”: Chia seeds soaked in water form a gel that replaces eggs and helps bind the batter.
💁♀️ Dietitian Tips
Tip 1: If you host, ask guests about food allergies before planning a menu so everyone can enjoy the food you serve.
Tip 2: Adding high-fiber ingredients like chia and whole grain flours helps families meet daily fiber needs. Calling these a “brownie-like cookie bar” can make them more appealing to picky eaters.
🍫 Ingredient Notes

- White whole wheat flour: Also called golden wheat flour. Unbleached and higher in fiber than all-purpose flour, with a milder flavor than regular whole wheat.
- Oat flour: Adds soluble fiber and softens the texture; you can make it from rolled oats in a blender.
- Chia seeds: When soaked, they form a gel that works as an egg substitute and contribute fiber and protein.
- Olive oil: I use extra virgin olive oil for healthy fats and good flavor.
- Sugar: A mix of granulated sugar (or coconut sugar) and brown sugar gives structure and flavor. Light or dark brown sugar both work; dark will produce slightly darker blondies.
- Vanilla: Pure vanilla extract brightens the flavor, especially with whole grain flours.
- Chocolate chips: Use a vegan, dairy-free brand if you need the blondies to be dairy-free. You can also use vegan white chocolate chunks or chips.
👩🍳 How to Make Chocolate Chip Vegan Blondies

Summary of the steps—scroll to the recipe card for exact measurements and full instructions.
- Preheat oven to 375°F and line a bar pan or sheet pan with parchment paper.
- Stir chia seeds into water in a small bowl and set aside for 5–10 minutes to form a gel.
- Use baking soda, not baking powder.
- Whisk together the dry ingredients (white whole wheat flour, oat flour, baking soda, salt) and set aside.
- In a large bowl, mix sugar, brown sugar, olive oil, and vanilla until combined.
- Add the chia gel to the wet mixture and mix well.
- Fold half the flour mixture into the wet ingredients, then add the rest and mix just until combined.
- Stir in chocolate chips.
- Spread the batter evenly in the prepared pan, pressing down with the palm of your hand.
- Bake 20–25 minutes until the top and edges are golden. For gooey blondies, remove at about 22 minutes; for firmer blondies, bake closer to 26 minutes.
- Cool completely, slice, and serve.
💡 Helpful Tips
- Let the chia soak for at least 5–10 minutes so it forms a gel; this improves structure.
- If you prefer, you can substitute eggs for the chia (then the recipe is no longer vegan).
- Melted butter or other neutral oil can replace olive oil, but melted butter is not vegan.
- Flaxseed gel (flax “egg”) is an equal substitute for chia if you prefer—note it adds a different texture and flavor.
- All-purpose flour can replace the white whole wheat and oat flour, though fiber will be lower.
- Make oat flour at home by blending rolled oats until fine.
- Always check labels if cooking for someone with allergies, especially chocolate chips and packaged flours.
- Parchment paper makes slicing and cleanup easier; you can also grease the pan well.
- Store cooled leftovers in an airtight container.

📖 Recipe

Vegan Blondies
Equipment
- 2 Mixing bowls
- 1 Small bowl
- Measuring cups and spoons
- 1 Sheet pan or bar pan
Ingredients
- 2 tablespoons chia seeds
- 6 tablespoons water
- 1 1/4 cups white whole wheat (golden wheat) flour (or all-purpose)
- 3/4 cup oat flour (or all-purpose)
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1 teaspoon vanilla
- 3/4 cup granulated sugar
- 1/2 cup brown sugar
- 1/2 cup extra virgin olive oil
- 6 ounces chocolate chips (vegan if needed)
Instructions
- Preheat oven to 375°F. Line a bar pan or baking sheet with parchment paper.
- Combine chia seeds and water in a small bowl, stir, and let sit 5–10 minutes until gel forms.
- In a separate bowl, whisk together white whole wheat flour, oat flour, baking soda, and salt. Set aside.
- In a medium bowl, mix sugar, brown sugar, olive oil, and vanilla until well combined.
- Stir the chia gel into the sugar and oil mixture and mix well.
- Add half the flour mixture to the wet ingredients and mix until mostly incorporated, then add the rest and mix just until combined.
- Fold in the chocolate chips.
- Spread the batter evenly in the prepared pan, pressing down with the palm of your hand.
- Bake about 22 minutes, or until the edges are golden. For gooey blondies remove early; for firmer blondies bake a few minutes longer.
- Allow to cool completely before slicing into squares.
Notes
- If not using parchment, grease the pan well.
- A 9×13 baking dish can substitute for a bar pan.
- Let chia sit 5–10 minutes to gel for best structure.
- The finished dough will be thick and slightly oily—that’s normal.
- Use light or dark brown sugar depending on the color and flavor you prefer.
- All-purpose flour can replace the flours listed but will reduce fiber.
- Flaxseed gel can substitute for chia; eggs can replace the chia but will remove the vegan status.
- Melted butter can replace olive oil but makes the recipe non-vegan.
- For a firmer, cookie-like texture bake 24–26 minutes.
