Dump unsweetened cocoa powder in the crock pot and 3 other simple pantry staples to get a treat so delicious. Your husband will be begging for more this Father's Day!

This 4-ingredient slow cooker vintage depression cake using unsweetened cocoa powder is the kind of simple, no-fuss dessert our grandmothers would have loved. It leans on pantry staples and skips eggs, butter, and milk—just like the original Depression-era “wacky” or “crazy” cakes that made do with what families had on hand. You literally dump cocoa powder and three other basics right into the crock pot, give it a stir, and let it bake itself into a moist, chocolatey treat. It’s perfect for busy days, and it feels extra special for Father’s Day when you want something homemade, comforting, and rich without turning on the oven.

Spoon this warm chocolate depression cake straight from the slow cooker into bowls and top with a scoop of vanilla ice cream, a dollop of whipped cream, or even just a splash of cold milk over the top. For a simple Father’s Day touch, drizzle with chocolate syrup or caramel sauce and add a few berries or sliced bananas. It also tastes great cooled and sliced, served with coffee after dinner or with a glass of cold milk for an afternoon treat.

Servings: 6-8

1 cup unsweetened cocoa powder

Lightly grease the inside of your slow cooker insert with a thin coat of cooking spray or a bit of oil to help prevent sticking.

Pour the unsweetened cocoa powder into the bottom of the slow cooker insert so it forms a dark, even layer. This should look like a rich pile of cocoa across the bottom.

Add the all-purpose flour and granulated sugar directly on top of the cocoa powder in the slow cooker.

Use a whisk or wooden spoon to gently stir the dry ingredients together right in the crock pot until the cocoa, flour, and sugar are evenly combined and no streaks of cocoa remain.

Pour the water over the dry mixture in the slow cooker. Stir well, scraping the bottom and sides, until you have a smooth, fairly thin batter with no big lumps of dry ingredients.

Smooth the top of the batter with the back of a spoon so it cooks evenly. Cover the slow cooker with its lid.

Cook on HIGH for 2 to 2 1/2 hours, or on LOW for 3 1/2 to 4 hours, until the cake is set in the center. A toothpick or butter knife inserted into the middle should come out with moist crumbs but not wet batter.

Once done, turn off the slow cooker and let the cake sit, covered, for about 10 to 15 minutes to finish setting and to cool slightly.

Serve the cake warm, scooping it directly from the slow cooker into bowls. Store any leftovers covered in the refrigerator for up to 3 days and reheat individual portions gently in the microwave.

For a slightly richer flavor while still keeping the spirit of a Depression-style pantry cake, you can swap 1/2 cup of the water for cooled coffee, which deepens the chocolate taste without adding more ingredients to your shopping list. If your family prefers things less sweet, reduce the sugar to 1 1/2 cups; the cake will still be moist and chocolatey. You can also stir in 1 teaspoon of vanilla extract if you have it on hand, or sprinkle a small handful of chocolate chips or chopped nuts over the top of the batter before cooking for a more indulgent Father’s Day twist. For picky eaters who don’t love super dark chocolate, serve their portions with extra whipped cream or ice cream to mellow the cocoa flavor. Food safety tips: Make sure the cake reaches a safe, fully cooked texture in the center—no wet batter should remain. Keep the slow cooker covered while cooking so it maintains proper temperature. Once the cake has cooled to room temperature, refrigerate leftovers within 2 hours and reheat only what you plan to eat. Always use clean utensils when scooping from the slow cooker to avoid introducing bacteria into the leftovers.
