Ingredients for 7 brew sugar free blondie

Pantry staples plus a few specialty touches—these ingredients create blondies that taste indulgent but stay sugar-free.

The 7 Brew sugar substitute is the MVP here—grab the granulated version if you can, not the powdered. It caramelizes beautifully during baking for that signature blondie flavor. Walmart or Target usually stock it, but check the baking aisle at Whole Foods if you want to splurge on a larger bag. Almond flour can be pricey, but the blanched kind from Bob’s Red Mill is worth it for that lighter texture. Toast your walnuts yourself—toss them in a dry pan for 3-4 minutes until fragrant. That little effort makes a huge difference in flavor. If you’re short on time, pre-toasted walnuts from the store work too, just skip the salt they add.

No vanilla bean paste? Double the regular vanilla extract—it won’t be identical, but you won’t taste the difference in the final blondies. Swapping almond flour? Oat flour works at a 1:1 ratio, but the texture will be denser. Want extra crunch? Add 0.25 cup chopped pecans or toasted coconut flakes. The xanthan gum is non-negotiable for that perfect fudgy texture—don’t skip it. If you’re out, psyllium husk powder at half the amount can work in a pinch. And if you’re baking at high altitude? Add 0.25 tsp more baking powder to prevent sinking.

These blondies keep beautifully—3-4 days in an airtight container at room temperature, or up to 1 week in the fridge. For longer storage, freeze portions on parchment paper for up to 3 months. I like to wrap them individually in parchment before freezing so I can grab just one when I need a treat. Reheat in the microwave for 10 seconds to restore that crispy edge. Pro tip: Sprinkle with a pinch of flaky salt right after baking while they’re still warm—trust me, it takes them to the next level.

Step-by-step instructions for sugar-free blondies with 7 Brew

Here’s how to make these decadent blondies that taste rich and fudgy but skip the sugar entirely.

First, toast the 0.5 cup chopped walnuts in a dry skillet over medium heat for 3-4 minutes, stirring constantly until they’re fragrant and just beginning to turn golden. Watch them closely—they go from pale to nutty brown in seconds. Remove from heat and let cool completely before using. This step adds depth of flavor that makes these blondies taste truly indulgent.

While the walnuts toast, take the 0.75 cup unsalted butter from the refrigerator and cut it into ½-inch cubes. This keeps the butter cold for even baking and prevents the blondies from spreading too much. I like to use my chef’s knife for this—just chop the butter while it’s still firm but not frozen solid.

In a medium bowl, whisk together the 2 whole large eggs, 2 tsp vanilla extract, and 1 tbsp vanilla bean paste until fully combined. The paste will add those little specks of vanilla flavor that make all the difference in homemade treats. In a separate bowl, sift together the 2 cups almond flour, 1.5 cups 7 Brew sugar substitute, 1 tsp ground cinnamon, 0.5 tsp baking powder, 0.5 tsp sea salt, and 0.25 tsp xanthan gum. This ensures everything is evenly distributed and prevents lumps.

I always sift the dry ingredients first—it’s like giving your blondies a head start. The xanthan gum might seem like a tiny amount, but it’s what gives these blondies that perfect fudgy texture without needing sugar to bind everything together.

Add the dry ingredients to the wet mixture and stir with a spatula until just combined. Don’t overmix—you’re looking for a thick, slightly crumbly batter that still holds together when pressed. Now comes the fun part: fold in the cold cubed butter using a rubber spatula. Work quickly but gently to cut the butter into the batter without melting it completely. You want pea-sized pieces distributed throughout—this creates those beautiful pockets of flavor and texture.

Finally, fold in the toasted walnuts. I like to distribute them evenly but leave a few clusters for that classic blondie look. The batter will be thick and almost dough-like—this is perfect for sugar-free baking. If it seems too dry, add 1 teaspoon almond milk (not in the original list, but I keep it handy for adjustments).

Preheat your oven to 350°F and line an 8×8-inch baking pan with parchment paper, leaving an overhang on the sides for easy removal. Spoon the batter into the pan and spread it evenly with a spatula, pressing down gently to create an even surface. The blondies will have a thick, fudgy texture, so don’t worry if it looks dense—this is exactly what we want.

Bake for 20-25 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 center should look slightly underdone—it’ll continue cooking as it cools. Here’s the thing—if you open the oven door early, the blondies might sink in the middle. Let them bake undisturbed until you see that perfect golden edge.

Remove the blondies from the oven and let them cool in the pan for 15 minutes. This resting period allows them to set properly and prevents them from falling apart when you cut. I know it’s tempting to dig in immediately, but trust me—waiting makes all the difference.

Once cooled, lift the blondies out using the parchment overhang and transfer to a wire rack. Cut into 16 squares (4 rows of 4) using a sharp knife. For perfectly clean cuts, dip the knife in hot water between each slice. Store any leftovers in an airtight container at room temperature for up to 5 days, though they rarely last that long in my house!

Troubleshooting perfect results

Blondies Too Dry?

If your blondies turn out dry, it’s usually because the sugar substitute didn’t caramelize enough or the oven ran too hot. First, make sure you’re using granulated 7 Brew—the powdered form can burn faster.

Also, reduce your oven temp to 325°F and bake for 5-10 minutes longer to let the sugar substitute develop that golden, fudgy texture. A light spray of almond milk (just 1 tsp) on the batter before baking can also add moisture without altering flavor. 💧

Cakey Texture?

Cakey blondies happen when too much mixing incorporates air or when the butter melts too quickly. To prevent this, fold the butter in last and keep it cold. Also, don’t overmix the batter—just combine until just combined.

If your blondies still turn out cakey, try adding 1 extra tbsp of almond flour and reduce the baking powder by 0.125 tsp. The xanthan gum is key here—never skip it—it’s what gives blondies their signature fudgy bite. 🍞

Blondies Spread Too Much?

Excessive spreading is usually caused by warm butter or an oven that’s too hot. Chill your batter for 15-20 minutes before baking to firm it up, and use cold butter cubes (not softened).

If your pan is too small, switch to a 9×9-inch pan for better rise control. Pro tip: Press the batter down firmly before baking to create a thicker center that resists spreading. 🧈

Sugar Substitute Not Caramelizing?

The 7 Brew sugar substitute needs high heat and time to caramelize properly. If your blondies taste bland, increase baking time by 5 minutes and check the oven temp with an oven thermometer—many ovens run hot.

For extra caramelization, sprinkle a pinch of sea salt on top right after baking while still warm. This enhances the sweetness and adds a buttery depth. 🌶️

Blondies Sticking to Pan?

Even with parchment paper, blondies can stick if the pan isn’t properly lined or the butter leaks. Double-check your parchment—it should cover the entire bottom and sides. If using a glass or dark pan, bake at 325°F to prevent over-browning.

For stubborn sticking, let the blondies cool completely in the pan before lifting. If they still resist, run a thin knife around the edges to loosen them before cutting. ⏰

Walnuts Burning?

Toasted walnuts burn quickly—watch them like a hawk! Remove them from the pan as soon as they’re lightly golden (about 3-4 minutes). For extra insurance, toast them in the oven at 350°F for 8-10 minutes instead.

If you burn them, chop them finely and mix them in—you’ll still get crunch, just with less bitterness. 🥜
