Upside Down Cinnamon Cake: Sticky, Spiced & Easy

This upside down cinnamon cake flips the usual fruit-based version on its head, layering a buttery, brown sugar and cinnamon topping beneath a soft, tender vanilla cake. As it bakes, the topping caramelizes into a glossy, sticky glaze that soaks into the cake’s base, creating a moist, spiced dessert that’s as beautiful as it is delicious. It’s a simple, rustic cake that works for breakfast, brunch, or dessert, and the technique is forgiving enough for beginner bakers.

Ingredients

1/2 cup (1 stick / 113 g) unsalted butter, melted, plus more for greasing the pan
1 cup (200 g) packed light brown sugar
1 tablespoon (8 g) ground cinnamon
1 1/2 cups (188 g) all-purpose flour
1 1/2 teaspoons baking powder
1/2 teaspoon salt
1/2 cup (1 stick / 113 g) unsalted butter, softened
3/4 cup (150 g) granulated sugar
2 large eggs, at room temperature
1 teaspoon vanilla extract
1/2 cup (120 ml) whole milk, at room temperature

Instructions

Preheat your oven to 350Â°F (175Â°C). Grease a 9-inch round cake pan (at least 2 inches deep) with butter or nonstick spray.
In a small bowl, stir together the melted butter, brown sugar, and cinnamon until it forms a thick, sandy paste. Spread this mixture evenly over the bottom of the prepared pan. Set aside.
In a medium bowl, whisk together the flour, baking powder, and salt.
In a large bowl, beat the softened butter and granulated sugar with an electric mixer on medium speed until light and fluffy, about 2â€“3 minutes. Add the eggs one at a time, beating well after each addition, then beat in the vanilla.
With the mixer on low speed, add the flour mixture in three additions, alternating with the milk, beginning and ending with the flour. Mix just until combinedâ€”do not overmix.
Spoon the batter over the brown sugar mixture in the pan and smooth the top with a spatula.
Bake for 35â€“40 minutes, or until a toothpick inserted into the center comes out clean and the top is golden brown. If the top browns too quickly, loosely cover with foil after 25 minutes.
Let the cake cool in the pan on a wire rack for exactly 10 minutes. Then run a knife around the edge, place a serving plate over the pan, and carefully invert the cake. If any topping sticks to the pan, scrape it off and spread it over the cake.
Let the cake cool for at least 20 more minutes before slicing. Serve warm or at room temperature.

Tips

Don’t skip the 10-minute rest: Inverting too soon lets the hot topping run off; waiting too long makes the cake stick to the pan. Set a timer.
Use room-temperature ingredients: Cold eggs or milk can make the batter curdle, resulting in a denser cake. Let them sit out for 30 minutes before starting.
Line the pan with parchment: For extra insurance, cut a parchment circle to fit the bottom of the pan and place it over the brown sugar mixture before adding the batter. This guarantees a clean release.
Check for doneness early: Ovens vary, so start checking at 30 minutes. A toothpick inserted in the center should come out with just a few moist crumbs, not wet batter.

Serving Suggestions

Serve this cake warm with a dollop of lightly sweetened whipped cream or a scoop of vanilla ice creamâ€”the contrast of cold and warm is delightful. For brunch, pair it with a cup of strong coffee or chai tea. It’s also delicious with a drizzle of caramel sauce and a sprinkle of toasted pecans.

Variations

Apple Cinnamon: Thinly slice 1â€“2 apples and arrange them over the brown sugar mixture before adding the batter. The apples soften and create a fruity, caramelized layer.
Nutty Crunch: Add 1/2 cup (60 g) of chopped pecans or walnuts to the brown sugar topping for added texture.
Spiced Cake: Add 1/2 teaspoon of nutmeg and 1/4 teaspoon of cloves to the flour mixture for a warmer spice profile.
Whole Wheat: Substitute half of the all-purpose flour with whole wheat flour for a heartier, slightly nutty flavor.

Storage and Reheating

Store leftover cake in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 4 days. The topping will soften and become stickier over time. To reheat, place a slice on a microwave-safe plate and heat in 15-second intervals until warm, or warm in a 300Â°F (150Â°C) oven for 5â€“8 minutes. For longer storage, wrap the unfrosted cake tightly in plastic wrap and freeze for up to 3 months; thaw overnight in the refrigerator before serving.

Frequently Asked Questions

Can I use a different pan size? Yes, you can use a 9-inch square pan or an 8-inch round pan. The baking time will change slightlyâ€”square pans may bake faster, and 8-inch pans may need a few extra minutes. Check for doneness with a toothpick.

Why did my cake stick to the pan? This usually happens if the cake wasn’t cooled for the full 10 minutes, or if the pan wasn’t greased well. Make sure to grease the pan thoroughly, and use the parchment circle trick for extra security.

Can I make this cake gluten-free? Yes, substitute the all-purpose flour with a 1:1 gluten-free baking flour blend that contains xanthan gum. The texture will be slightly more tender, but the flavor remains excellent.

Can I reduce the sugar? You can reduce the brown sugar in the topping to 3/4 cup (150 g) and the granulated sugar to 1/2 cup (100 g), but the cake will be less sweet and the topping less caramelized. The texture may also be slightly drier.

Why is my topping runny? A runny topping usually means the cake was inverted too early, before the topping had set. Alternatively, your butter may have been too hot when mixed with the sugar, causing it to separate. Make sure the melted butter is not overly hot, and always rest the cake for the full 10 minutes.

Can I use salted butter? Yes, just reduce the added salt to 1/4 teaspoon, or omit it entirely if you prefer a less salty flavor.
