Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 25 minutes
• Total Time: 45 minutes
• Servings: 12 cupcakes
• Yield: 12 cupcakes
• Dietary Type: Vegetarian

Ingredients

• 1/4 cup butter or margarine, melted
• 1/2 cup brown sugar, firmly packed
• 1 tablespoon water
• 36-48 walnut halves
• 1 cup cake flour, sifted
• 1/3 cup baking cocoa
• 1/2 teaspoon baking soda
• 1/4 teaspoon salt
• 1/4 cup margarine, softened or shortening, melted
• 3/4 cup white sugar
• 1 egg
• 1 teaspoon vanilla
• 1/2 cup water or 1/2 cup 1% low-fat milk
• 2/3 cup sweetened condensed milk
• 1 cup semi-sweet chocolate chips
• 2 tablespoons butter

Equipment Needed

• 12-cup muffin tin
• Small saucepan
• Mixing bowls
• Sifter
• Electric mixer (optional)
• Wire racks

Instructions

1. Preheat your oven to 350°F (175°C).
2. Thoroughly grease a 12-cup muffin tin. This is crucial for easy removal later! Use butter, shortening, or cooking spray, making sure to get into every nook and cranny.
3. In a small saucepan, combine the 1/4 cup of melted butter (or margarine), 1/2 cup of firmly packed brown sugar, and 1 tablespoon of water.
4. Simmer the mixture over low heat for 1 minute, stirring constantly until the brown sugar is dissolved and the mixture is smooth. Be careful not to burn it!
5. Place 3-4 walnut halves in the bottom of each of the prepared muffin cups. Arrange them evenly so that each cupcake gets a nice nutty base.
6. Evenly divide and pour the cooked brown sugar mixture over the walnuts in the muffin cups. This will create the gooey, caramelized topping.
7. In a medium-sized bowl, sift together 1 cup of cake flour, 1/3 cup of baking cocoa, 1/2 teaspoon of baking soda, and 1/4 teaspoon of salt. Sifting ensures a light and airy texture. Set this dry mixture aside.
8. In a separate, larger bowl, cream together 1/4 cup of softened margarine (or melted shortening) and 3/4 cup of white sugar. If using an electric mixer, beat on medium speed until light and fluffy. If mixing by hand, make sure the margarine is truly softened for easier creaming.
9. Beat in 1 egg and 1 teaspoon of vanilla extract until well combined.
10. Gradually blend in the dry ingredients alternately with the 1/2 cup of water (or milk), beginning and ending with the dry ingredients. This means you’ll add about 1/3 of the dry ingredients, then half of the water, then another 1/3 of the dry ingredients, the remaining water, and finally the last of the dry ingredients. This prevents the batter from becoming too tough. Mix until just combined; avoid overmixing.
11. Fill the muffin cups approximately 1/2 full with the batter. This will give them room to rise without overflowing.
12. Bake in the preheated oven for 20-25 minutes, or until a wooden skewer inserted into the center comes out clean. Keep a close eye on them, as baking times can vary depending on your oven.
13. Once baked, remove the muffin tin from the oven and immediately invert the cupcakes onto wire racks to cool. This allows the gooey topping to drip down the sides and creates that signature “upside-down” look. Leave them inverted until completely cool.
14. While the cupcakes are cooling, prepare the chocolate topping. In a small saucepan, combine 2/3 cup of sweetened condensed milk and 1 cup of semi-sweet chocolate chips.
15. Cook over very low heat, stirring constantly, until the chocolate is melted and the mixture is smooth and thickened. This should take about 10 minutes. It’s crucial to use low heat and stir constantly to prevent the chocolate from scorching.
16. Stir in 2 tablespoons of butter until melted and incorporated. This adds richness and shine to the topping. Keep the topping warm until ready to use.
17. Once the cupcakes are completely cooled and inverted, spread the warm chocolate topping generously over the sides of each cupcake.
18. Enjoy!

Expert Tips & Tricks

• For an extra decadent flavor, add a pinch of espresso powder to the chocolate topping.
• If your cupcakes stick to the muffin tin even after greasing, try lining the cups with cupcake liners (though you’ll need to remove them before inverting).
• For a more intense chocolate flavor, use dark chocolate chips instead of semi-sweet.
• If the chocolate topping becomes too thick, add a tablespoon of milk or cream to thin it out.
• To make these ahead of time, bake the cupcakes and prepare the chocolate topping separately. Store the cupcakes at room temperature and the topping in the refrigerator. Reheat the topping gently before spreading.

Serving & Storage Suggestions

Serve these Upside-Down Ooey Gooey Chocolate Cupcakes slightly warm or at room temperature. They are delicious on their own or served with a scoop of vanilla ice cream. Store any leftover cupcakes in an airtight container at room temperature for up to 2 days or in the refrigerator for up to 5 days. The chocolate topping may harden slightly in the refrigerator, so you can gently warm the cupcakes in the microwave for a few seconds before serving to soften the topping. These cupcakes are not ideal for freezing, as the topping may become grainy upon thawing.

Variations & Substitutions

• Nut-Free: Omit the walnuts entirely or substitute with sunflower seeds or chopped pecans.
• Dairy-Free: Use a dairy-free margarine or shortening for the batter and chocolate topping. Substitute the sweetened condensed milk with a dairy-free condensed milk alternative (if available) or a mixture of coconut cream and sugar, reduced on the stovetop.
• Gluten-Free: Use a gluten-free all-purpose flour blend in place of the cake flour. You may need to add a binder like xanthan gum to improve the texture.
• Spice it up: Add a pinch of cayenne pepper to the chocolate topping for a kick.
• Seasonal: Top with fresh berries in the summer or a sprinkle of cinnamon in the fall.

FAQs (Frequently Asked Questions)

Q: Why are these called “Upside-Down” cupcakes?
A: Because they are inverted after baking, so the gooey walnut and caramel topping ends up on top!

Q: Can I use regular all-purpose flour instead of cake flour?
A: While you can, cake flour will give you a lighter and more tender cupcake. If you must substitute, use 1 cup of all-purpose flour minus 2 tablespoons, and add 2 tablespoons of cornstarch.

Q: My chocolate topping is too thick. What can I do?
A: Add a tablespoon of milk or cream and stir until smooth. You can also microwave it for a few seconds at a time, stirring in between, until it reaches the desired consistency.

Q: Do I have to use walnuts?
A: No, you can use other nuts like pecans or almonds, or even omit them altogether for a nut-free version.

Q: How do I prevent the cupcakes from sticking to the muffin tin?
A: Thoroughly grease the muffin tin with butter, shortening, or cooking spray. You can also use cupcake liners, but remember to remove them before inverting.
