If you’re craving something rich, chocolatey, and deeply satisfying—without the sugar crash—these no-bake keto peanut butter chocolate bars are about to become a staple in your fridge. They’re smooth, dense, and indulgent in that classic peanut butter–meets–chocolate way, but made with low-carb ingredients that still deliver on flavor and texture.
These bars are perfect when you want a dessert that feels like a treat, not a compromise. The peanut butter layer is thick and soft with just the right amount of sweetness, and the dark chocolate glaze on top adds a silky finish that snaps slightly when chilled. Best of all, there’s no oven involved—just mix, press, chill, and enjoy.
Tips for Perfect Results
Because this recipe is so simple, a few small details make a big difference.
- Use powdered sweetener. Powdered Swerve blends smoothly into the peanut butter layer without any gritty texture.
- Melt the butter and peanut butter fully. This helps everything combine evenly and creates a smooth, cohesive dough.
- Expect a dough, not a batter. The mixture should be thick and pressable—that’s exactly what you want.
- Press firmly and evenly. Using parchment paper and a flat-bottomed glass helps create clean, professional-looking bars.
- Melt the chocolate gently. Slow heat prevents the chocolate from seizing and keeps the glaze silky.
- Chill until fully set. Give the bars a full hour in the fridge so they slice cleanly.
