Ingredients You’ll Need

• 3 tablespoons monk fruit brown sugar: This sugar alternative adds a rich flavor without the calories. You can also try coconut sugar for a similar taste.
• 2 cups fresh blueberries: The star of the show! Choose plump, ripe berries; frozen can work, but fresh is best for flavor and texture.
• ⅔ cup all-purpose flour: This is the base of the cake. For a gluten-free option, you can substitute with a gluten-free flour blend.
• ½ teaspoon baking powder: Helps the cake rise for that lovely airy texture.
• ¼ teaspoon kosher salt: Enhances the sweetness and balances the flavors.
• ⅛ teaspoon baking soda: Works alongside the acid in the buttermilk to create a lighter cake.
• ⅓ cup monk fruit sweetener: Provides sweetness without the carbs. Granulated sugar can be used if you prefer.
• 2 tablespoons butter, melted: Adds richness and moisture to the cake.
• 1 large egg, beaten: Acts as a binder and gives structure to the cake.
• ½ teaspoon vanilla extract: A must for flavor depth—always use pure vanilla for the best flavor.
• ⅓ cup low-fat buttermilk: Keeps the cake moist and tender. If you don’t have buttermilk, a quick substitute is regular milk with a splash of vinegar.

How to Make Blueberry Upside Down Cake

1. Prepare the Ramekins: Spray four 5-ounce or 6-ounce ramekins with cooking spray. Sprinkle about 3 teaspoons of monk fruit brown sugar into each ramekin. Then, fill each with ½ cup of fresh blueberries, spreading them evenly across the bottom to ensure they caramelize perfectly.
2. Mix the Batter: In a bowl, whisk together the remaining dry ingredients (all-purpose flour, baking powder, salt, baking soda, and monk fruit sweetener) until combined. Add the egg, melted butter, vanilla extract, and buttermilk. Stir until just mixed; be careful not to overmix for a tender crumb.
3. Spoon the Batter: Evenly spoon the batter into the prepared ramekins, making sure each has a nice layer of batter over the blueberries (don’t worry if it seems a little thick; it will bake up perfectly).
4. Cooking Method: If using an air fryer, place the ramekins in the basket and air fry at 320°F for 14 to 15 minutes. Check for doneness at 12-13 minutes by inserting a toothpick in the center—if it comes clean, your cakes are ready! Alternatively, preheat your oven to 350°F and bake for 20 to 25 minutes until a toothpick inserted near the center comes out clean.
5. Cool and Serve: Let the cakes cool for about 5 minutes. Carefully run a small knife around the edges to loosen. Invert each ramekin onto a serving plate. If the tops have puffed up, gently trim them to make them level before flipping. Enjoy topped with a scoop of vanilla ice cream or a dollop of whipped cream for extra indulgence.

Storing & Reheating

To store your blueberry upside down cake, keep it in an airtight container at room temperature for up to two days. For longer storage, move it to the refrigerator, where it can last for up to a week. You can also freeze the cakes for up to 3 months; just wrap them tightly in plastic wrap and foil before placing them in a freezer-safe bag. To reheat, thaw in the fridge overnight, then pop in a preheated oven at 350°F for just a few minutes until warmed through. The texture will be deliciously tender, although you might find the blueberries are a bit softer after freezing.

Chef’s Helpful Tips

• Pay attention to the blueberries! Make sure they’re free from bruises and wash them gently to avoid bursting them.
• Always use room temperature eggs and buttermilk for a smoother batter and better rise.
• Avoid overmixing when combining the batter; this will keep your cakes light and fluffy.
• If you’re using frozen blueberries, do not thaw them before adding to the batter; this will help them hold their shape better during baking.
• Feel free to experiment! Replace blueberries with other fruits like peaches or strawberries for a fun twist.

Blueberry upside down cake has a certain charm that makes it a go-to dessert for any occasion. Not only is it quick and easy to whip up, but it’s also a treat that allows for creativity in the kitchen. Whether you follow this recipe to the letter or add your personal flair, I encourage you to enjoy every moment of the baking process. It’s all about bringing a little happiness into your day, bite by delicious bite!

Recipe FAQs

Can I use frozen blueberries in this recipe?

Absolutely! Frozen blueberries can be a wonderful substitute. Just be sure not to thaw them before baking, as this will help them maintain their shape and texture in the cake.

How do I know when my blueberry upside down cake is done?

The best way to check for doneness is by inserting a toothpick into the center of the cake. If it comes out clean or with just a few moist crumbs clinging to it, your cake is ready to be removed from the oven or air fryer.

Can I make this recipe in one large cake instead of multiple ramekins?

Yes! You can certainly bake this in a larger round cake pan. Just increase the bake time to about 25-30 minutes, keeping an eye on it towards the end.

What tips can you share for storing leftover cake?

If you have leftover cake, store it in an airtight container to keep it fresh. It’s best enjoyed within a few days, but you can refrigerate it as well. Just be aware that the texture may change slightly after a couple of days, but it will still taste fantastic!
