1 cup all-purpose flour – the base structure for our cake
3/4 cup granulated sugar – for sweetness and tenderizing the crumb
1/4 cup unsweetened cocoa powder – provides that deep chocolate flavor
2 tsp baking powder – helps the cake rise and become light
1/4 tsp salt – balances the sweetness and enhances flavors
1/2 cup milk – adds moisture to the batter
1/4 cup vegetable oil or melted butter – contributes to a tender texture
1/3 cup creamy peanut butter – the star ingredient for that unmistakable peanut butter taste
1 tsp vanilla extract – enhances all the other flavors
1 1/2 cups hot water – crucial for creating the gooey sauce as it cooks
1/2 cup chocolate chips (semisweet or milk chocolate) – for pockets of melted chocolate goodness

How to Make Slow Cooker Peanut Butter Cake

This recipe truly simplifies dessert making. You’ll be amazed at how easy it is to create such a decadent treat!

Step 1: Prepare your slow cooker. Lightly spray the inside with nonstick cooking spray or line it with parchment paper. This step is crucial for easy removal later.
Step 2: In a large bowl, combine the dry ingredients. Whisk together the 1 cup all-purpose flour, 3/4 cup granulated sugar, 1/4 cup unsweetened cocoa powder, 2 tsp baking powder, and 1/4 tsp salt until well combined. This ensures even distribution of leavening and flavor.
Step 3: Add the wet ingredients to the dry. Stir in the 1/2 cup milk, 1/4 cup vegetable oil (or melted butter), 1/3 cup creamy peanut butter, and 1 tsp vanilla extract. Mix until you have a thick, smooth batter. Don’t overmix!
Step 4: Transfer the batter to the slow cooker. Pour the peanut butter batter into your prepared slow cooker and spread it evenly across the bottom. This forms the base of your delicious cake.
Step 5: Add the chocolate chips. Sprinkle the 1/2 cup chocolate chips evenly over the top of the batter. These will melt into gooey pockets of chocolatey goodness.
Step 6: Create the magical sauce. Gently and slowly pour the 1 1/2 cups hot water over the chocolate chips and batter. Resist the urge to stir! This is what creates the self-saucing effect, turning into a luscious peanut butter chocolate sauce as it cooks. This is a key step in how to make slow cooker peanut butter cake.
Step 7: Cook until set. Cover the slow cooker and cook on HIGH for 2 to 2 1/2 hours. You’re looking for the top to be set, but the inside should remain soft and gooey. The aroma will become incredibly tempting during this time.
Step 8: Let it rest. Once cooked, turn off the slow cooker and let the cake rest, still covered, for about 15 minutes. This allows the sauce to thicken slightly.
Step 9: Serve and enjoy! Scoop the warm cake and its sauce directly from the slow cooker. This chocolate peanut butter crockpot recipe is best served warm with a scoop of vanilla ice cream or a dollop of whipped cream.

This peanut butter dessert slow cooker storage is simple and keeps the cake wonderfully moist. If you’re interested in more about food preservation, check out resources from experts.
