If you're looking for a "comfort food" dessert, try this easy gluten-free banana cake. Whip it up while your guests are sitting around after dinner, and in half an hour you'll have a warm cake fresh from the oven. My husband likes it with vanilla ice cream on top (gluten-free ice cream, of course).

There are numerous all-purpose gluten-free flour mixes you can use for this cake. Bob's Red Mill and Arrowhead Mills each offer one, or you could consider trying the pricier (but very popular) Williams-Sonoma Cup4Cup gluten-free flour blend.

As far as the rum goes, most rums are considered gluten-free (they're made from sugar cane, not from the gluten grains wheat, barley, and rye). However, you should steer clear of flavored rums, since the flavoring agent added to these rums could possibly contain gluten (even though it's unlikely). Almost all apple juice is gluten-free if you choose to use that instead of rum.

I prefer to use Singing Dog alcohol-free vanilla extract, as that's gluten-free and doesn't contain distilled alcohol that can be derived from gluten grains.

  • 1/2 cup raisins
  • 1 1/2 Tbsp dark rum or apple juice
  • 1 cup all-purpose gluten-free flour mix
  • 1/2 tsp baking powder
  • 1/2 tsp baking soda
  • 1/4 tsp salt
  • 1/4 tsp guar gum
  • 3/4 cup packed brown sugar
  • 1/4 cup butter or margarine, melted
  • 1/2 cup mashed ripe banana (equals 1 banana)
  • 3 Tbsp low-fat buttermilk (or fat-free yogurt, or soy yogurt)

  1. Preheat oven to 350 F and lightly grease an 8-inch square baking pan or a round pan of similar size.
  2. Put raisins in a small bowl, pour the rum or juice over them, and microwave on high for 1 minute. Remove from the microwave and set aside.
  3. Combine the flour, baking powder, baking soda, salt and guar gum in a bowl, stirring well with a whisk. Set aside.
  4. Combine brown sugar and melted butter or margarine in a large bowl. Beat with a mixer at medium speed until well blended.
