Keto Brownie Recipe

I hid a batch of these in the back of the freezer. Behind the frozen broccoli, which is my system.

Two days later, I walked into the kitchen in the middle of the afternoon and found two of my kids hunched over the counter, microwave running, splitting the last two. My oldest doesn’t even like brownies, or so I thought. He took a bite, looked up, and said, “This is keto?”

I rewrote this recipe from scratch after years of the old version being fine and not much more. This recipe delivers more.

And if you are looking for more keto desserts, don't miss my keto mug brownie.

Why These Come Out Fudgy Instead of Cakey

There’s no baking powder here, because I was going for a fudgy sugar-free brownie.  Leavening is what makes brownies cakey.

Instead, we lean towards a custard structure with the egg and fat. And because almond flour absorbs less liquid than wheat flour, we have a wet batter.

That’s a gift here. A wet batter with no leavener bakes into a fudgy brownie.

Why Allulose and Not Erythritol

I recommend that you use allulose for this recipe, not erythritol.

A brownie batter with erythritol can look great when it goes into the oven. Then it cools and crystals reform. You get grittiness and a cooling sensation on your tongue.

Allulose dissolves and stays dissolved, holds onto moisture, and browns. Brownies made with allulose stay soft on day three. Brownies made with erythritol get hard and sandy overnight.

It does have one quirk. Allulose browns faster than sugar so that the edges can get ahead of you. That’s why we’re at 325°F instead of 350°F.

Why the Full Minute of Whisking Matters

I want to explain the one minute whisk, so you aren't tempted to cut it short.

After the eggs go in, you beat the batter for sixty seconds. You are forcing fine air bubbles into the warm fat. In a batter with no leavener those bubbles are the only air the brownies will ever get. They hold their place as the batter sets. You end up with a velvety crumb instead of a heavy one.

The whisking buys the allulose more time to dissolve, too. When the batter goes glossy and it thickens slightly, you are there.

How to Tell When They’re Done

One thing that will throw you with this recipe. These brownies look underbaked when they are perfect. The center will appear to not be set and look almost wet.

These set when they cool because the cocoa butter and the almond fat re-solidify as the pan cools. So the pan comes out of the oven looking soft and firms up on the counter.

Trust the toothpick, not the color. You want moist crumbs clinging to it, not clean and not wet batter.

Make sure you give the full hour to cool. Cutting into them warm gets you a delicious pile of rubble. (Ask me how I know.)

Storing and Freezing

They keep five days in the fridge and three months in the freezer. I wrap them individually, which is the only reason there were any left for my kids to find.

Ten seconds in the microwave from frozen and you’ve got a warm, melty square on a Tuesday night.

What to Serve Them With

Warm brownie, ten seconds in the microwave, a scoop of keto coffee ice cream on top.

A spoonful of keto whipped cream is the lighter move, and it’s what I do when I’m serving these after a heavy dinner.

For a holiday dessert tray, I’ll cut these smaller, into 25 squares instead of 16, and put them out alongside keto cheesecake bites and keto chocolate bark.

If it’s fudge you’re really after, my keto chocolate fudge gets you there with no oven at all.
