Sugar-Free Fudgy Brownies with Jaca

By Jaca Kitchen · · Updated

These sugar-free fudgy brownies swap regular sugar for Jaca allulose, so you get deep, chocolatey, crackly-topped brownies with zero added sugar and about 95 calories each. They bake up dense and rich in one bowl — no melting chocolate, no mixer, no boxed mix.

This is a Jaca-adjusted, healthier version of the classic fudgy cocoa brownie: we replaced every bit of sugar with Jaca allulose at double the amount, so the texture stays soft and fudgy while the sugar drops to nothing. One quick note — allulose browns faster than sugar, so we bake a touch cooler and keep an eye on the top.

Ingredients:

  • ½ cup (113 g) unsalted butter, melted
  • 1 tablespoon neutral oil (avocado, light olive, or melted coconut oil)
  • 2¼ cups Jaca allulose (replaces 1⅛ cups sugar — a 2x swap)
  • 2 large eggs, at room temperature
  • 2 teaspoons pure vanilla extract
  • ½ cup (65 g) all-purpose flour
  • ½ cup (45 g) unsweetened cocoa powder
  • ¼ teaspoon salt
  • ½ cup sugar-free chocolate chunks or chips (optional)

Instructions:

  1. Preheat the oven to 325°F (165°C). Line an 8-inch square pan with parchment paper and lightly grease. (Allulose browns faster than sugar, so we bake a little cooler than a standard brownie.)
  2. In a medium bowl, whisk the melted butter, oil, and Jaca allulose together for about a minute, until glossy.
  3. Add the eggs and vanilla and beat for another minute, until the batter lightens in color.
  4. Sift in the flour, cocoa powder, and salt. Gently fold until just combined — do not overmix, or the brownies turn cakey.
  5. Pour the batter into the prepared pan and smooth the top. Scatter over the optional chocolate chunks.
  6. Bake 18–22 minutes, until the center is just set and a toothpick comes out with a few moist crumbs. Check at 18 minutes; if the top is browning quickly, tent loosely with foil.
  7. Cool completely in the pan before slicing into 16 squares — they firm up and turn extra fudgy as they cool.

Why Jaca? Allulose is a rare sugar that tastes and bakes like the real thing but has virtually no calories and doesn’t spike blood sugar. Swapping it in at 2x keeps these brownies every bit as sweet and fudgy — just without the sugar.
