This is very good and so easy to make! My family loved it! It's pretty sweet though, so I will probably reduce the brown sugar a little bit next time. I found the recipe in the Dec. 2006 issue of Everyday Food.
Batter:
Cooking Spray
1 1/2 cups all-purpose flour
2 envelopes Fleischmann's® RapidRise Yeast (I used 4 1/2 tsp. Fleishmann's instant yeast)
1/4 cup sugar
1/4 teaspoon salt
2/3 cup milk (very warm 120-130°F)
1/4 cup butter, melted
1 egg (I beat it first)
Cinnamon Mixture:
3 tablespoons butter, softened (I used 2 T.)
3/4 cup packed brown sugar (will probably decrease to 1/2 cup next time)
1 1/2 teaspoons ground cinnamon
Icing:
1 cup powdered sugar (I used 1/2 cup)
1 to 2 tablespoons milk (didn't measure)
1 tablespoon butter, melted (I omitted)
1/2 teaspoon pure vanilla extract
Recipe
MIX batter ingredients together in a pre-sprayed 8x8-inch baking dish (I mixed it in a bowl first). Let rest for 10 minutes. Combine cinnamon mixture in a small bowl by mixing with fork.
TOP batter evenly with cinnamon mixture. Using fingers, poke topping thoroughly into batter.
BAKE by placing in a COLD oven; set temperature to 350°F. Bake 25-30 minutes, until lightly browned and firm in center. Cool 10 minutes. Combine icing ingredients and drizzle over warm cake.
Recipe Note: If desired, batter may be mixed in a separate bowl. Proceed as directed above.
