Scale
The Pumpkin Cake
- 1½ cups (190g) all-purpose flour

- 1 tsp pure vanilla extract
The Cream Cheese Frosting
- 8 oz (225g) full-fat brick cream cheese, completely softened
- 4 tbsp (60g) unsalted butter, completely softened

- 1 tsp pure vanilla extract

Instructions
- Prepare the slow cooker. Line the slow cooker insert with parchment paper — a circle on the bottom and a strip around the sides with overhang handles. Grease the parchment lightly with butter or cooking spray. Set aside.
- Whisk the dry ingredients. In a large bowl, whisk together the flour, granulated sugar, brown sugar, baking powder, baking soda, salt, cinnamon, ginger, nutmeg, cloves, allspice, and cardamom (if using) until fully combined with no lumps.
- Combine the wet ingredients. In a separate medium bowl, whisk together the pumpkin puree, melted butter, eggs, milk, and vanilla extract until smooth and well combined.
- Make the batter. Pour the wet ingredients into the dry ingredients and fold with a rubber spatula until just combined — do not overmix. A few small streaks of flour are fine. The batter will be thick, smooth, and deeply orange.
- Pour and level. Pour the batter into the prepared slow cooker insert and spread into an even layer with the spatula, smoothing the top as much as possible.
- Set up the slow cooker. Lay 2 full sheets of paper towels flat across the top of the slow cooker opening. Place the lid on top of the paper towels, securing them between the lid and the rim of the slow cooker. This absorbs condensation during cooking.
- Cook. Set the slow cooker to HIGH. Cook for 2.5 to 3.5 hours without lifting the lid. Begin testing for doneness at the 2.5-hour mark by inserting a toothpick into the center of the cake — it is done when the toothpick comes out clean or with just a few moist crumbs attached, not wet batter. The edges will have pulled slightly away from the sides and the top will have a set, matte appearance.
- Cool completely. Turn off the slow cooker. Remove the insert and allow the cake to cool in the insert for 30 minutes. Use the parchment handles to lift the cake out onto a wire rack. Cool to complete room temperature — at least 1.5 to 2 hours — before frosting. For best results, refrigerate for 1 hour after reaching room temperature before applying the frosting.
- Make the cream cheese frosting. Beat the softened cream cheese and softened butter together in a bowl using a hand or stand mixer on medium speed until completely smooth, about 2 minutes. Scrape down the bowl thoroughly. Add the sifted powdered sugar in two additions, beating on low after each until incorporated, then increasing to medium until smooth. Add the vanilla extract and pinch of cinnamon. Beat until light and fluffy, about 1 minute more. Add heavy cream or milk one tablespoon at a time if the frosting is too thick to spread easily.
- Frost and finish. Transfer the completely cooled cake to a serving plate or board. Spread the cream cheese frosting generously over the top and sides of the cake using a spatula or the back of a spoon — it does not need to be perfectly smooth; a rustic, swirled finish suits this cake beautifully. Scatter the toasted pecan halves over the frosted top. Dust lightly with ground cinnamon through a small sieve just before serving.
- Slice and serve. Using a sharp knife dipped in hot water and wiped dry between cuts for the cleanest slices. Serve at room temperature or slightly chilled.
Notes
- Pumpkin puree, not pumpkin pie filling. This is the most important ingredient distinction in the recipe. Pumpkin pie filling already contains sugar, spices, and other additives and will throw the entire recipe off. Look for cans labeled “100% Pure Pumpkin” with pumpkin as the only ingredient.
- Room temperature eggs and dairy. Cold eggs can cause the melted butter to seize into clumps when mixed together. Room temperature ingredients combine more smoothly and produce a more uniform batter.
- Do not overmix the batter. Overmixing develops gluten and produces a tough, dense cake rather than a tender one. Fold just until no large streaks of flour remain.
- The paper towel trick. Two sheets of paper towels under the lid prevent condensation from dripping onto the cake surface during cooking. Without it, the top of the cake can become wet and steamed rather than properly set. Use it every time you bake in the slow cooker.
- Frosting only a fully cooled cake. Cream cheese frosting melts immediately on a warm cake. Patience here is rewarded with clean, beautiful frosting that stays where you put it.
- The cake improves with time. The spices deepen and the crumb becomes even more moist overnight. If you can resist the urge to cut into it immediately, a day-old pumpkin cake is genuinely better than same-day.
- Slow cooker size affects timing. A wider oval slow cooker produces a thinner cake that cooks faster (check at 2 hours). A smaller, deeper insert produces a taller cake that may need the full 3.5 hours. Always use the toothpick test rather than a fixed time.
