3 large eggs

1 tsp vanilla extract

2 tbsp ground cinnamon

Honey Glaze

1 cup powdered sugar

2–3 tbsp honey

½ tsp vanilla extract

Instructions

1. Make the Cake Batter

Preheat oven to 350°F. Grease a 9×13 baking pan.

In a bowl, whisk together cake mix, mashed sweet potatoes, oil, milk, eggs, and vanilla until smooth and creamy.

2. Create the Cinnamon Swirl

⇆

In a separate bowl, combine brown sugar, cinnamon, and melted butter.

Mix until it resembles a thick pourable paste.

3. Assemble the Cake

Pour half the cake batter into the pan.

Spoon half the cinnamon mixture on top and gently swirl with a knife.

Add the remaining cake batter, then swirl again with the rest of the cinnamon mixture.

4. Bake

Bake for 35–45 minutes, or until a toothpick comes out clean.

5. Make the Honey Glaze

Whisk powdered sugar, honey, milk, and vanilla until smooth and drizzle-ready.

Adjust thickness with more milk or powdered sugar as needed.

6. Glaze & Serve

Pour glaze over the warm cake and let it soak into every swirl and crevice.

Slice into squares and enjoy!
