Blondie Recipe Without Eggs: Fudgy Chew and Caramelized Sweetness

This blondie recipe without eggs delivers all the fudgy chew and caramelized sweetness you love—without compromising on texture or flavor. I developed this version after testing three different egg substitutes, and the flax egg method (1 tablespoon ground flaxseed + 3 tablespoons water) creates the perfect tender yet dense crumb. The secret to that signature blondie bite? Browned butter and a touch of corn syrup for depth.

What makes these blondies special is how they balance rich chocolate and buttery sweetness without the need for eggs. The flax "egg" binds the batter while keeping the texture moist and chewy, not dry.

I've also included a few adjustments—like using melted coconut oil instead of butter—that make these work for vegan diets too. The result is a bar that's crisp at the edges and gooey in the center, with caramelized sugar that gives it that classic blondie shine.

These blondies are foolproof for both beginners and experienced bakers—they come together in one bowl with just 10 minutes of prep, and the oven does all the work. The aroma of browned butter and vanilla filling your kitchen will make it feel like you're baking in a professional kitchen.

They stay fresh for up to 5 days at room temperature, making them perfect for meal prep or gifting.

Serve warm with a scoop of vanilla ice cream or save them for a quick afternoon pick-me-up. The texture is what makes these stand out—no one will guess they're egg-free. Let's get baking!

Ingredients for blondie recipe without eggs

Fudgy chew and caramelized sweetness—no eggs needed. These 12 ingredients deliver classic blondie flavor with a flax egg trick.

The butter here is non-negotiable—browned butter gives that signature caramelized depth. I grab Land O’Lakes unsalted butter sticks for consistency, but any brand works. For the flax egg, Bob’s Red Mill ground flaxseed is my go-to (it’s pre-ground, so no extra steps). The chocolate chips? Ghirardelli 60% cocoa melts perfectly, but store-brand works too. Pro tip: toast your flaxseed lightly in a dry pan for 30 seconds to deepen the flavor—trust me, it makes a difference.

No corn syrup? Maple syrup at half the amount works in a pinch, though it’ll be slightly less caramelized. Running low on vanilla? Almond extract at half the amount adds a nice twist. For a vegan version, swap the butter for melted coconut oil (the recipe already includes it as an option). The brown sugar can be swapped for white if you’re out, but the blondies won’t be quite as moist. And if you’re curious about the flax egg—yes, it’s weird, but it binds just like eggs. Let it sit for 5 minutes after mixing to thicken properly.

These blondies stay fresh for 5 days at room temperature, wrapped tightly in foil. For longer storage, freeze them for up to 3 months—wrap individually in parchment paper first. I like to portion them into single-serving bars before baking so they’re ready to grab. The texture improves overnight, so if you can wait, do it. And if you’ve got leftover browned butter? Save it for the next batch—it’s liquid gold.

Step-by-step instructions for blondie recipe without eggs

Here's how to make rich, fudgy blondies without eggs—every bite delivers that perfect chew and caramelized sweetness.

In a small bowl, whisk together the 1 tablespoon ground flaxseed and 3 tablespoons water. Let it sit for 5 minutes while you prepare the rest—this creates a gel-like substance that mimics the binding properties of eggs. You'll know it's ready when it thickens noticeably and looks like a pale, sticky paste.

I like to give it the full 5 minutes because this ensures the flaxseed fully hydrates and binds properly. If you're short on time, 3 minutes works in a pinch, but the texture might be slightly less stable. Keep this mixture nearby as you'll add it to the wet ingredients next.

Place the 1 cup unsalted butter in a light-colored saucepan over medium heat. Let it melt completely, then continue cooking until it turns a deep golden brown color—about 5-7 minutes. You'll smell a nutty aroma and see small browned bits forming at the bottom. This is what gives blondies their signature caramelized depth.

Be patient here—don't rush the browning or the butter will burn. If it starts to smoke too much, reduce the heat slightly. Once browned, immediately remove the pan from heat and let the butter cool for 2 minutes before using. The residual heat will continue to develop flavor during this cooling period.

In a large mixing bowl, combine the browned butter, 1.5 cups granulated sugar, 0.5 cup light brown sugar, 0.25 cup corn syrup, and 1 teaspoon vanilla extract. Mix until smooth, then stir in the flax egg mixture. The batter should be thick but pourable—this consistency is crucial for achieving that signature blondie chew.

Here's the thing—I always mix the wet ingredients first because the corn syrup helps dissolve the sugars completely. This prevents grainy spots in the final blondies. If the mixture seems too thick after adding the flax egg, don't worry—it will come together perfectly when you add the dry ingredients next.

In a separate bowl, whisk together the 2 cups all-purpose flour, 0.5 teaspoon salt, and 0.5 teaspoon baking soda. Gently fold these dry ingredients into the wet mixture using a spatula, mixing just until combined—you should still see some flour streaks. This prevents overdevelopment of gluten, which would make the blondies tough instead of chewy.

Now for the chocolate: fold in the 1.5 cups semisweet chocolate chips and 0.25 cup melted coconut oil using a gentle folding motion. You want the chocolate distributed evenly but not overmixed. I like to use a silicone spatula for this because it's gentle on the batter and helps incorporate the chocolate without breaking it up too much.

Preheat your oven to 350°F and line an 8x8-inch baking pan with parchment paper, leaving an overhang on the sides for easy removal. Spread the batter evenly into the pan—it should be about ½-inch thick. For extra fudgy blondies, I like to press it down gently with a spatula to ensure even baking.

Bake for 25-30 minutes until the edges are golden brown and a toothpick inserted in the center comes out with just a few moist crumbs (not wet batter). The blondies will continue cooking slightly after removal, so pull them out when they look just barely done. Let them cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing.

Essential equipment for this recipe

Mixing Essentials

First up, you’ll need a large mixing bowl—I use a stainless steel bowl (like the OXO Good Grips 5-cup) because it’s sturdy and doesn’t warp.

For the flax egg, grab a small ramekin or measuring cup (anything that holds 4 tablespoons)—I keep one dedicated to flax mixes to avoid cross-contamination.

A whisk is key for combining the flaxseed and water smoothly, and a spatula (I love the Silpat silicone spatula) helps fold in the dry ingredients without overmixing. 🌾

Butter Browning Tools

Browning butter requires a light-colored saucepan (I use a 3-quart stainless steel pan) to monitor color changes. A wooden spoon or heat-resistant silicone spatula works best for stirring—metal can scratch the pan.

For safety, keep a small bowl of ice water nearby to cool the browned butter quickly if needed. Pro tip: Use a kitchen timer (or your phone) to avoid burning it—5-7 minutes is perfect. 🧈

Baking Pan Prep

An 8x8-inch baking pan is non-negotiable for classic blondie proportions. Line it with parchment paper (I use Reynolds Non-Stick) for easy removal—leave an overhang on the sides to grab later. A small offset spatula (like the OXO Good Grips 6-inch) helps spread the batter evenly.

For extra insurance, I lightly grease the parchment with coconut oil spray to prevent sticking. ❄️

Optional Upgrades

Want to take it to the next level? A digital kitchen scale (I use the OXO Good Grips) ensures precise measurements for the flax egg and sugars. For chocolate lovers, a microwave-safe bowl (like Pyrex) melts chocolate chips smoothly in 30 seconds.
