Steps

Before you start

Line your slow cooker with parchment paper for easy removal
Bring sourdough discard to room temperature
Measure out ingredients and have them ready before mixing

1
Prepare slow cooker
- Line a 6-quart slow cooker with parchment paper, allowing it to hang slightly over the sides for easy removal later.
- This prevents the bread from sticking and makes removal simple after cooking.

Tip: Parchment paper prevents the delicate bread from breaking apart when you remove it from the slow cooker.
2
Combine dry ingredients
- In a medium mixing bowl, whisk together flour (1.5 cups), baking powder (2 tsp), baking soda (0.5 tsp), salt (0.5 tsp), and crushed dried lavender (1.5 tsp).
- Set aside.
- The lavender should be finely crushed between your fingers to release its fragrance and distribute evenly.

Tip: Crushing the lavender buds by hand ensures they blend smoothly into the batter without visible specks that might be unpleasant.
3
Mix wet ingredients
- In a large bowl, whisk together room-temperature sourdough discard (1.5 cups), eggs (2 large), granulated sugar (0.75 cup), honey (⅓ cup), milk (0.5 cup), vegetable oil (0.25 cup), vanilla extract (1 tsp), and lemon zest (1 tsp).
- Whisk until well combined and smooth, about 2 minutes.
- The mixture should look pale and slightly frothy.

Ready when: Mixture is pale and slightly frothy
Tip: Using room-temperature discard and eggs helps the batter emulsify smoothly and bake evenly in the slow cooker.
4
Combine wet and dry
- Pour the wet ingredients into the dry mixture and fold together with a spatula until just combined, about 10–12 strokes.
- Don't overmix; some lumps are fine.
- The batter should be thick but pourable.

Ready when: Just combined with some lumps remaining
Tip: Overmixing develops gluten and toughens the crumb; stop as soon as you see no pockets of dry flour.
5
Fold in blueberries
- Reserve 0.25 cup (about 35 g) of the freshest blueberries and fold the remaining blueberries (about 1.25 cups) gently into the batter with a few strokes of the spatula.
- The berries should be distributed evenly but not crushed.

Ready when: Blueberries are gently folded in and evenly distributed
Tip: Reserving some berries for topping gives you pockets of fruit flavor and a pretty finish.
6
Pour into slow cooker
- Pour the batter into the prepared slow cooker.
- It should come about three-quarters of the way up the sides.
- Smooth the top with a spatula and scatter the reserved blueberries over the surface, pressing them in gently so they sink slightly but remain visible.
+ Show details− Hide details
Ready when: Batter fills slow cooker three-quarters full with berries on top
Tip: Don't fill the slow cooker more than three-quarters full, or the bread may overflow at the edges during cooking.
7
Cover and cook on low
- Cover the slow cooker and cook on LOW heat for 3 hours.
- Do not lift the lid during cooking, as sudden heat loss can deflate the bread.
- The bread is done when a toothpick inserted into the center comes out clean or with just a few moist crumbs clinging to it, and the edges are visibly set and slightly pulling away from the sides.

Ready when: Toothpick inserted in center comes out clean or with just a few moist crumbs; edges pull away from sides
Tip: Resist the urge to peek; opening the lid drops temperature and adds moisture, extending cooking time by 15–30 minutes.
8
Cool in slow cooker
- Turn off the slow cooker and let the bread rest inside with the lid off for 10 minutes.
- This allows the carryover heat to gently set the structure without overdrying.
- The bread will set up further as it cools.
+ Show details− Hide details
Ready when: Bread is set and slightly cooled
Tip: This resting period prevents the bread from being too fragile when you remove it.
9
Remove from slow cooker
- Grasp the overhanging parchment paper and carefully lift the bread onto a wire cooling rack or cutting board.
- Let it cool to room temperature, about 10 minutes, before slicing.
- The bread will continue to set and will be easier to slice once fully cooled.

Ready when: Bread is cool enough to handle and slice cleanly
Tip: Slicing while slightly warm may cause the crumb to tear; waiting until completely cool ensures clean slices.

Tips

The slow cooker creates a gentler, more humid baking environment than a conventional oven, resulting in a bread with superior moisture and a tender, almost custard-like crumb. The sourdough discard adds subtle tang that complements the lavender without making the bread taste sour.
This recipe uses active discard (discard taken just after feeding, when bubbly and at peak vigor). If your discard is thinner or thicker than expected, adjust the milk by 1–2 tablespoons to keep the batter at a thick, pourable consistency—roughly the texture of pancake batter.
For an extra burst of lavender flavor without bitterness, make a lavender-honey drizzle: warm 2 tablespoons honey with 0.5 tsp crushed lavender for 1 minute off heat, then drizzle over cooled bread slices.
Sourdough discard tea bread freezes beautifully and reheats beautifully. This makes it perfect for batch-baking—make two loaves at once if your slow cooker is large enough (use two slow cookers side by side), and you'll have fresh-tasting bread for weeks.

Make ahead

You can prepare the dry mixture up to 1 day ahead in an airtight container. Mix the wet ingredients no more than 1 hour before combining and cooking, or the sourdough discard may overproof and make the batter too loose.

Storage & reheating

Room temperature: covered with a kitchen towel, up to 2 days. Refrigerator: wrapped tightly in plastic wrap or in an airtight container, up to 5 days. Freezer: wrap the entire loaf in plastic wrap and then foil; freeze up to 3 months. Thaw overnight in the refrigerator and warm gently in a 300°F (150°C) oven for 10–15 minutes before serving, or slice and toast individual slices.

Substitutions

fresh blueberries → frozen blueberries (no need to thaw) or fresh raspberries. Use the same weight. Frozen berries will bleed slightly, creating a pink-tinted crumb, which is lovely. Raspberries add a tangier flavor.
dried culinary lavender buds → 2 tsp of finely grated lemon zest or 1 tsp of culinary rose water, reduced from 1 tsp to 0.5 tsp vanilla extract. Rose water is fragrant and pairs beautifully with blueberries; use sparingly as it's potent. Lemon zest keeps the citrus-floral profile.
raw or pasteurized honey → maple syrup in the same amount. Maple syrup gives a slightly earthier, mellow sweetness. The bread will be less fragrant but equally moist.
neutral vegetable oil → melted unsalted butter or coconut oil. Butter adds richness and a subtle vanilla note. Coconut oil keeps the bread lighter and dairy-free if needed.
