With Liliya!
I created this recipe after a friend brought over a chocolate-dipped biscotti that tasted amazing but left me with a sugar crash. I wanted something with all the crunchy, chocolaty joy—but made with whole grains and natural sweetness. My kids love dunking these into warm milk, and I love that they keep well all week. We’ve even made mini versions for lunchbox treats!

- Maple Syrup or Honey. Adds just the right amount of natural sweetness.
- Egg. Helps bind the ingredients and gives structure during baking.
- Baking Powder. Ensures a light rise in the first bake.
- Vanilla Extract. Optional but enhances both chocolate and peanut butter flavors.

Expert Tips for Peanut Butter Chocolate Oat Biscotti
Use creamy peanut butter. Natural peanut butter with no added sugar or oil works best.
Don’t overmix the dough. Stir until just combined to keep the biscotti tender inside.
Cool before slicing. Letting the log rest makes slicing easier and reduces crumbling.
Slice with a sharp, serrated knife. This gives clean, even cuts.
Flip during the second bake. Toast both sides for a perfect crunch.
Peanut Butter Chocolate Oat Biscotti Recipe Variations
- Make it gluten-free. Use a gluten-free flour blend and certified GF oats.
- Add dried fruit. Fold in dried cranberries, raisins, or chopped dates for a touch of sweetness.
- Add espresso powder. A pinch deepens the chocolate flavor beautifully.
- Use almond butter. For a softer, sweeter, nutty flavor.
- Make it vegan. Use a flax egg (1 tbsp flaxseed meal + 3 tbsp water) instead of a regular egg.
Storing / Freezing Peanut Butter Chocolate Oat Biscotti
To store: Keep biscotti in an airtight container at room temperature for up to 1 week.
To freeze: Store cooled biscotti in a freezer-safe container for up to 2 months. Let thaw at room temperature or toast briefly before serving.
To freeze dough: Shape into a log, wrap tightly, and freeze. Thaw slightly before baking.
How to Pack These for Work and School
Once baked and fully cooled, these biscotti are ideal for tossing into lunch bags or snack boxes. They won’t crumble like softer cookies, and they hold up beautifully without refrigeration. For school, wrap individual pieces in parchment or stash a few in a small reusable container. For work, pair it with your favorite coffee in a travel mug, and you’ve got the ultimate midday mood-lifter.
FAQs About Peanut Butter Chocolate Oat Biscotti
Can I make these nut-free?
Yes! Use sunflower seed butter in place of peanut butter, and omit the chopped nuts.
Do I need to bake them twice?
Yes. The first bake sets the dough, and the second bake creates that iconic crunch.
Why is my dough too sticky or dry?
If too sticky, add a tablespoon of flour. If too dry, mix in a splash of milk.
What’s the best chocolate to use?
Semi-sweet or dark chocolate chips or chunks work best. Chop a bar for rustic, melty bits.
Can I shape them into smaller logs for mini biscotti?
Absolutely! Just reduce the baking time by a few minutes.
Can I skip the chocolate drizzle?
Yes, but it adds such a delicious finish! Try a peanut butter drizzle instead for a fun twist.
