Equipment (8)

Large baking sheet
Parchment paper
Medium mixing bowl
Small mixing bowl
Measuring cups and spoons
Microplane zester or fine grater (for ginger)
Wooden spoon or silicone spatula
1-tablespoon cookie scoop (optional, for uniform sizing)

Steps

Before you start

Preheat oven to 375°F (190°C) and line a large baking sheet with parchment paper
Roast the sweet potato cubes first so they're ready to mix (about 20 minutes ahead)
Have your sourdough discard at room temperature
Measure all ingredients before mixing for easier assembly

1
Roast sweet potato cubesOven 375°F / 190°C
- Toss the sweet potato cubes with 1 tablespoon olive oil and ¼ teaspoon sea salt on a large baking sheet.
- Spread in a single layer.
- Roast at 375°F (190°C) for 18–20 minutes, stirring halfway through, until the edges are caramelized and the centers are very tender when pierced with a fork.
- Let cool for 5 minutes on the baking sheet.

Ready when: Edges are caramelized and centers yield to a fork when pierced
Tip: Don't skip the caramelization—it deepens flavor and adds structure to the bites. Watch the timing; overroasting makes them dry.
2
Combine dry ingredients
- While the sweet potato roasts, measure the rolled oats, hemp seeds, ginger, cinnamon, nutmeg, and black pepper into a medium mixing bowl.
- Whisk together until the spices are evenly distributed and the ginger specks are visible throughout.

Ready when: Spices are evenly distributed with no clumps
Tip: Grating the ginger finely ensures it distributes evenly without creating large chunks in the bites.
3
Mix wet ingredients
- In a small mixing bowl, whisk together the sourdough discard, maple syrup, and vanilla extract until smooth and homogeneous.
- No streaks of discard should remain.

Ready when: Mixture is smooth and evenly combined
Tip: Whisking fully incorporates the discard, which prevents pockets of uneven fermentation flavor.
4
Fold ingredients together
- Pour the wet ingredients into the dry mixture and gently fold with a spatula until just combined.
- The batter will be thick and sticky.
- Once the roasted sweet potato has cooled slightly, gently fold it in, being careful not to break the pieces apart.
- A few small broken pieces are fine; the goal is tender chunks throughout.

Ready when: All ingredients are evenly distributed with no streaks of dry mix
Tip: Fold gently rather than stirring vigorously—overmixing can break down the sweet potato chunks and create a dense texture.
5
Shape and place bites
- Line a second clean baking sheet with parchment paper (or reuse the first one after wiping it).
- Using a 1-tablespoon cookie scoop (or two teaspoons), portion the batter into 24 roughly equal mounds, spacing them about 1.5 inches (4 cm) apart.
- If using spoons, scoop with one spoon and push off onto the sheet with the other.
- Don't flatten or press down; let them hold their natural humped shape.

Ready when: 24 mounds placed with space between each
Tip: Consistent sizing helps them bake evenly. A scoop ensures uniformity and saves time.
6
Bake until crispy edgesOven 375°F / 190°C
- Bake at 375°F (190°C) for 12–15 minutes, until the tops are set and dry to the touch, and the edges are light golden brown.
- The centers should still yield slightly to pressure.
- Do not overbake; they will firm up as they cool.

Ready when: Tops are dry to the touch, edges are light golden, centers yield slightly to pressure
Tip: Set a timer for 12 minutes and check; ovens vary. The bites will seem slightly soft when hot but will firm as they cool—this is correct.
7
Cool on the sheet
- Remove from the oven and let the bites cool on the baking sheet for 5 minutes.
- This allows the structure to set fully without becoming brittle.
- They should firm up noticeably.

Ready when: Bites are firm to the touch and hold their shape when gently pressed
Tip: Resist moving them too soon; they'll break apart if handled while still hot.

Tips

Sourdough discard adds a subtle tang and boosts nutrition without requiring any special prep—just use what you'd normally discard. A bubbly, active discard adds slight lift; an older, less bubbly one is fine too.
These bites strike a balance between chewy (from the discard and syrup) and crispy (from roasting the sweet potato). Don't expect them to be super dense; they're meant to be snack-sized with a pleasant tender crumb.
The combination of ginger, cinnamon, and nutmeg creates a warming spice profile that complements the earthy sweetness of roasted sweet potato. Adjust spice amounts to your preference.
Toast the hemp seeds in a dry skillet for 2–3 minutes before adding if you want a deeper, nuttier flavor. Let them cool first.

Make ahead

Store cooled bites in an airtight container for up to 5 days at room temperature, or prepare the mixture 1 day ahead and refrigerate, then portion and bake as directed. You can also freeze unbaked portions on a sheet for 2 hours, transfer to a freezer bag, and bake directly from frozen, adding 3–4 minutes to the bake time.

Storage & reheating

Room temperature: up to 5 days in an airtight container. Refrigerator: up to 7 days in an airtight container (they'll soften slightly). Freezer: up to 3 weeks in a freezer-safe container or bag. Thaw at room temperature for 30 minutes before eating, or eat straight from the freezer for a firmer texture.

Substitutions

hulled hemp seeds → Sunflower seeds or pumpkin seeds (same amount). Both provide similar nutrition and a pleasing crunch. Sunflower seeds have a milder flavor; pumpkin seeds are earthier.
pure maple syrup → Agave nectar or coconut nectar (same amount). Both work well, though coconut nectar has a subtler sweetness and may require slightly longer baking to firm up.
fresh ginger root → Ground ginger (½ teaspoon instead of 1 tablespoon fresh). Ground ginger is more concentrated, so use less. The flavor will be slightly sharper but still warming.
old-fashioned rolled oats → Gluten-free rolled oats (same amount) or a mix of rolled oats and ground oats for a finer crumb. Gluten-free oats work perfectly; ground oats create a more compact, dense bite. Use no more than ¼ cup ground oats as a replacement for whole oats.
