From the MyKitchenBank Kitchen

A rich, moist cake infused with maple syrup and bourbon, baked in a slow cooker for deep flavor and tender crumb. Pecans are folded into the batter and toasted on top for a crunchy contrast. The slow, indirect heat creates a cake that's impossibly soft inside with a subtle caramel undertone.

Steps

Before you start

Line your slow cooker (5–6 quart) with parchment paper so the cake releases cleanly
Bring all wet ingredients to room temperature; cold batter won't bake evenly in a slow cooker
Have pecans toasted or ready to toast just before assembling
Read through the slow cooker baking step—low heat and timing are critical

1
Prep slow cooker
- Line the inside of a 5–6 quart slow cooker with parchment paper, letting it overhang the sides for easy removal later.
- This prevents sticking and allows the cake to release cleanly.
+ Show details− Hide details
Tip: Parchment is essential for slow cooker cakes—they stick more than oven-baked ones.
2
Combine dry ingredients
- In a medium bowl, whisk together flour (2 cups / 250 g), baking powder (2 teaspoons / 10 g), baking soda (½ teaspoon / 2.5 g), salt (½ teaspoon / 3 g), cinnamon (1 teaspoon / 2.5 g), and nutmeg (¼ teaspoon / 0.5 g).
- Set aside.

Ready when: Mixture is uniform and no lumps remain
Tip: Whisk instead of stirring to aerate and combine the leavening agents evenly.
3
Cream butter and sugar
- In a large bowl, beat softened butter (¾ cup / 170 g) and brown sugar (1 cup / 200 g) together with a wooden spoon or mixer for 2–3 minutes until light and fluffy.
- The mixture should look creamy and pale, not grainy.
+ Show details− Hide details
Ready when: Mixture is light, fluffy, and noticeably increased in volume
Tip: Room-temperature butter creams faster and incorporates more air, yielding a lighter cake.
4
Add eggs one at a time
- Add one room-temperature egg to the creamed mixture and beat until fully incorporated, about 1 minute.
- Add the second egg and beat another minute until the batter looks smooth and homogeneous.
- Do not overmix once all eggs are in.

Ready when: Batter is smooth with no visible streaks of egg white
Tip: Adding eggs slowly prevents curdling and ensures a tender crumb.
5
Mix in maple and bourbon
- In a small bowl, stir together maple syrup (½ cup / 120 ml), bourbon whiskey (3 tablespoons / 45 ml), and vanilla extract (1 teaspoon / 5 ml).
- Add this mixture to the creamed batter and fold in gently with a spatula, mixing until just combined.
- Do not overmix.
+ Show details− Hide details
Ready when: No streaks of syrup remain visible; batter is smooth
Tip: Gentle folding preserves the aeration from creaming—overmixing deflates the batter and toughens the cake.
6
Alternate dry mixture and sour cream
- Add one-third of the dry mixture to the batter and fold in gently.
- Add half the sour cream (½ cup / 120 g) and fold in.
- Repeat: one-third dry, then remaining sour cream, then final dry mixture.
- Stop folding as soon as no white streaks remain.
+ Show details− Hide details
Ready when: No visible white streaks; batter is smooth and light tan
Tip: Alternating dry and wet ingredients, starting and ending with dry, prevents overmixing and keeps the batter light.
7
Fold in chopped pecans
- Gently fold the chopped pecans (1.5 cups / 150 g) into the batter until evenly distributed throughout.
- The batter is now ready to pour into the slow cooker.
+ Show details− Hide details
Ready when: Pecans are evenly distributed with no clumps
Tip: Chopping the pecans finely helps them distribute evenly and prevents them from sinking to the bottom.
8
Pour and arrange pecans
- Pour the batter into the parchment-lined slow cooker, smoothing the top with a spatula.
- Arrange the whole pecan halves (¾ cup / 75 g) in a single layer on top, pressing them gently into the batter.
- They will toast and create a crunchy, attractive topping.

Ready when: Batter is level and pecans are arranged in a decorative pattern
Tip: Pressing pecans partway into the batter anchors them so they don't slide or float during cooking.
9
Prepare water bath
- Measure ½ cup (120 ml) of water into a small bowl.
- You'll add this in the next step to create a gentle, humid environment in the slow cooker.
10
Slow cook on low
- Place a paper towel or clean kitchen towel over the slow cooker's insert to absorb condensation.
- Set the slow cooker to LOW heat.
- Carefully pour the ½ cup water into the space between the parchment-lined batter and the ceramic insert walls—not onto the cake itself.
- Cover and cook for 2 hours on low.
- The cake should pull away from the sides slightly and a toothpick inserted in the center should come out with just a few moist crumbs—not wet batter.
+ Show details− Hide details
Ready when: Toothpick inserted in center comes out with a few moist crumbs; cake pulls away from sides and springs back lightly when touched
Tip: Low heat is critical—slow cookers on high will overheat the edges and dry out the cake. The water bath keeps the environment humid so the cake stays moist.
11
Cool in slow cooker
- Turn off the slow cooker.
- Remove the lid and let the cake rest inside for 15 minutes.
- This brief cooling allows the structure to set while the cake is still warm and moist.
+ Show details− Hide details
Ready when: Cake is warm but not piping hot; it should feel set around the edges
Tip: Leaving the lid off allows steam to escape so the top doesn't become soggy.
12
Turn out onto wire rack
- Gently lift the parchment paper overhang and transfer the warm cake to a wire cooling rack.
- Let it cool to room temperature, about 15 minutes, before serving.
- The parchment will peel away easily.
+ Show details− Hide details
Ready when: Cake is room temperature to the touch; parchment peels away cleanly
Tip: Cooling on a rack, not a flat surface, allows air to circulate underneath so the bottom doesn't steam and become soggy.

Good to know

Tips

Slow cooker models vary in temperature; if your cake browns too quickly, line the slow cooker insert with an extra layer of foil before adding parchment. This slows heat transfer.
For a bourbon glaze, reduce 3 tablespoons maple syrup and 1 tablespoon bourbon in a small saucepan over medium-low heat for 1–2 minutes, then drizzle over the cooled cake.
The bourbon mellows significantly during cooking—if alcohol sensitivity is a concern, reduce bourbon to 1½ tablespoons.
Pecans can be toasted in a 350°F (175°C) oven for 8–10 minutes before adding to the batter for deeper nutty flavor, but don't toast the pecans for the topping—they will toast in the slow cooker.

Make ahead

You can prepare the dry ingredients up to 2 days ahead in an airtight container. The batter itself is best mixed no more than 30 minutes before cooking, as the leavening agents are most active when the cake enters the slow cooker.

Storage & reheating

Store the cooled cake covered at room temperature for up to 2 days. For longer storage, wrap tightly and refrigerate for up to 5 days, or freeze for up to 3 months (thaw at room temperature for 2–3 hours before serving). Reheat in a 300°F (150°C) oven for 10 minutes if you prefer it warm.

Substitutions

bourbon whiskey → 3 tablespoons dark rum or brandy. Maintains the same depth of flavor; rum adds slight spice, brandy adds fruitiness.
pecan halves → walnuts or hickory nuts, chopped. Walnuts are earthier; hickory nuts are sweeter. Use the same weight.
sour cream → ½ cup Greek yogurt (drained if very thick) or crème fraîche. Maintains moisture and tang; Greek yogurt may make the cake slightly denser.
packed light brown sugar → 1 cup granulated sugar plus 1 tablespoon unsalted butter (mixed into creaming step). Granulated sugar alone will make the cake less moist and more crumbly, so the extra butter compensates.
