Instructions

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!
