Peanut Butter Chocolate Bars

Peanut Butter Chocolate Bars

By Kate

Dense bars blending peanut butter and chocolate chips in a buttery base. Uses a slight twist by swapping some flour with oat flour for texture; maple syrup partially replaces granulated sugar for depth. The mix is pressed—not dropped—into a lined pan for even thickness. Bake until a knife comes out mostly clean but retains crumbs. Cooling fully before slicing ensures bars hold shape. Adjust bake time slightly for chewiness or firmness; aroma darkens, edges set, center soft but not wet. Simple steps but fragile balance; easy to dry out or underbake without attention to sensory cues.

Introduction
Peanut butter and chocolate chips. Always a solid combo. But bars need respect; dense textures can dry easily or stay gummy. Timing’s a dance. Smells hit you around 15 minutes in—nutty, buttery, toasted sugar. Edges will look more toasted, center slightly puffy but set. Pressing dough into pan keeps thickness consistent so baking uniform. Flours matter; oat flour gives chew and slight grain, helps with structure versus pure white flour. Maple syrup adds moisture, cuts back need for all sugar; also toasty notes. Chips don’t want overmixing or they’ll melt and lose distinct bites. Cooling is crucial—bars are fragile until fully cool, slice too soon and bars crumble. Using parchment paper sling saves mess, no scraping stuck bits. Simple ingredients, few tricks, but all important if you want bars that hold.

Ingredients

  • 1 cup all-purpose flour
  • 1/2 cup oat flour
  • 3/4 teaspoon baking powder
  • 1/2 teaspoon fine sea salt
  • 1/2 cup unsalted butter softened
  • 1/2 cup creamy peanut butter
  • 3/4 cup maple syrup
  • 1/2 cup light brown sugar packed
  • 2 large eggs room temperature
  • 1 teaspoon pure vanilla extract
  • 3/4 cup semi-sweet chocolate chips
  • 1/2 cup peanut butter chips
  • About the ingredients

    Swapping some all-purpose flour for oat flour adds chew and a subtle toasted aroma. If unavailable, use all-purpose only but bars will be softer and less textured. Maple syrup replaces part of the granulated sugar to deepen sweetness without grit and adds moistness; if omitted use all brown sugar but dough gets stiffer. Peanut butter chips can be swapped for white chocolate chips or chopped roasted peanuts for crunch contrast. Butter should be softened at room temp but not melted; melted butter flattens bars and ruins texture. Eggs at room temp mix in better, especially crucial when creaming with butter and peanut butter. Vanilla is simple aroma lift; don’t skip it. Salt is key to balance sweetness and amplify peanut flavor—don’t reduce.

    Method

  • Heat oven to about 380°F. Line a 9x13 pan with parchment making sure paper hangs over edges for easy removal. Don't skip slipping the paper in or bars stick big time.
  • Whisk together the flours, baking powder, and salt until homogenous. Sifting optional but breaks up lumps; flour combo adds chew and slight nuttiness, not just plain white flour.
  • Cream butter and peanut butter till fluffy but not melted. Room temp key here to trap air; too soft and texture falls flat. Mixer paddle or hand mixer—whichever—works.
  • Add brown sugar and maple syrup gradually, beat till just mixed. You want uniform but not whipped or grainy. Add eggs one at a time, fully incorporate before next. Pour vanilla for fragrance mid-mix.
  • Slowly add dry mix; fold or mix on low speed until dough just comes together. Don't overwork or bars toughen.
  • Gently fold in chocolate and peanut butter chips by hand to avoid breaking chips or overworking dough. Texture bursts vs meltdown.
  • Press dough evenly into prepared pan using a spatula or lightly oiled fingers. Aim for thickness variance under 1/4 inch or bars bake unevenly.
  • Bake 25 to 30 minutes. Watch edges turn golden and surface set but center still soft. Knife inserted near center pulls out mostly clean with a few moist crumbs—not sticky batter. For chewier bars drop bake time by 4-5 minutes; underbake a touch. Overbaking dries bars and dulls flavor.
  • Cool completely on wire rack before slicing. Warm bars fall apart under knife pressure. Use parchment to lift entire slab out. Cut with sharp knife warmed briefly under hot water then dried for clean cuts.
  • Store airtight at room temperature up to 4 days or freeze individually wrapped for longer. Bars lose moisture fast if uncovered.
  • Technique Tips

    Step order matters for texture. Creaming butter and peanut butter traps air, giving volume and preventing dense bars. Adding dry mix slowly helps avoid overmixing, which causes toughness. Folding chips avoids crushing and meltdowns. Using parchment with overhang means you lift bars whole—no stuck bits or breakage. Pressing dough evenly ensures consistent bake; use spatula or lightly oiled fingers but don’t pack too tight or bars get tough. Watch for visual cues over time—edges golden brown, surface just set not cracked. Insert knife to test doneness; want moist crumbs, not wet batter. Baking longer means drier, firmer bars. Cooling completely sets structure; slice warm and bars crumble. Use warming knife trick for clean cuts. Cooling times vary by kitchen humidity and pan material; be adaptable.

    Chef's Notes

    • 💡 Measure flours accurately; it matters. Too much all-purpose, bars dry out. Oat flour adds texture. If no oat—just all-purpose is fine. Just softer, lighter.
    • 💡 Creaming is key; air matters. Beat room temp butter with peanut butter till fluffy but not melted. Otherwise, dense bars. Don't rush this step.
    • 💡 Watch edges as they bake. Golden brown, surface set but puffed. If edges darkening fast, center still softifies, could be done. Check with knife for crumb test.
    • 💡 Cooling lots matters; warm bars crumble. Use the wire rack. Wait till bars set completely. Lift them out with parchment overhang. Makes slicing better, cleaner.
    • 💡 Sharp knife hack; dip in hot water, wipe dry. Cuts through bars cleanly. Prevents messy, crumbling edges. Keeping knife warm eases cutting. Less pressure needed.

    Kitchen Wisdom

    How can I make these less sweet?

    Reduce syrup, brown sugar. Note texture changes; drier bars might result. Tweak to taste carefully.

    What's the best way to store these bars?

    Airtight container to keep moisture. Room temp for 4 days. Freeze wrapped tightly for longer. Easy to thaw.

    My bars turned out too dry, why?

    Check bake time; overbaking causes dryness. Next, maybe too much flour mixed in, watch those measurements.

    Can I substitute something in the recipe?

    Yes, use sunflower butter for nut-free. Almond flour could work in place of oat flour. Texture shift possible, monitor.
