The Best Low-FODMAP Banana Cake with Peanut Butter and Chocolate Frostings; Gluten-free, Dairy-free

Talk about delicious. This is the BEST ever low-FODMAP Banana Cake, layered with low-FODMAP Peanut Butter and Chocolate Buttercreams. Amazing flavors in every bite. I am very serious about my low-FODMAP Cakes.

A banana cake is different from a banana bread (I have a delicious low-FODMAP Banana Bread recipe), as a banana cake will be lighter and fluffier.  I like a banana bread for a casual weekend morning, while this cake goes perfectly on the table for a baby shower or holiday event.

I used low-FODMAP Peanut Butter Buttercream in the layers, with low-FODMAP Chocolate Buttercream on top, but anything goes!  I love adding some crunch to the frosting with chopped peanuts and/or rice crisps.

You can also substitute my low-FODMAP Salted Caramel Frosting, low-FODMAP Cream Cheese Frosting or my low-FODMAP Maple Buttercream on this low-FODMAP Banana Cake.  All are delicious and totally change the flavor and feel of the Banana Cake.

This low-FODMAP Banana Cake reminds me of my newest low-FODMAP Happy Bar flavor, Banana Chocolate Glee.  A perfect combination isn’t it?

The Best Low-FODMAP Banana Peanut Butter and Chocolate Layer Cake; Gluten-free, Dairy-free

Although this recipe has not been tested, a single serving should be low-FODMAP based on the ingredients

Serves 24 or more

Prep time: 20 min plus 20 min for decorating/assembly

Bake time: 40 min *Note: since ovens vary, begin checking your low-FODMAP cake 5-10 minutes prior to end time to prevent overbaking

Total time: About 80 minutes

Bake 350 F

Ingredients

  • 3 cups Authentic Foods GF Classical Blend Flour mix (this is my preferred low-FODMAP, GF flour.See my low-FODMAP bake off blog for the reason why!)
  • 1 & 1/2 tsp xanthan gum, if not added to your low-FODMAP flour choice
  • 1 tbsp baking powder
  • 2 tsp baking soda
  • 1 tsp salt
  • 2 tsp cinnamon
  • 2 cups sugar
  • 1 & 1/2 cups canola oil
  • 4 large eggs, room temperature
  • 2 tsp fresh squeezed lemon juice
  • 2 tsp vanilla
  • 2 cups mashed ripe banana (about 4 bananas- this is 12 low-FODMAP servings if using ripest banana.  There will be higher FODMAP content depending on how ripe your bananas are)
  • Vegetable shortening, for greasing
  • Frosting: see below for low-FODMAP peanut butter frosting and follow link for low-FODMAP chocolate buttercream frosting
    • If you are using 2 frostings, then cut recipe by 1/2 for each one
  • Garnish: chopped peanuts and chocolate shavings

Directions

  • Preheat oven to 350 F and place racks in center of oven
  • Line 2-4 round cake pans (depending on how many layers you like, can also cut layers into 2 halves after baking) with parchment and grease with vegetable shortening
  • Place low-FODMAP flour, xanthan gum, baking soda, baking powder, salt, cinnamon in medium bowl and combine by hand
  • In another bowl of electric mixer, with flat paddle, beat sugar, oil and eggs until smooth, about 1 min
  • Add vanilla and mix well
  • Slowly add lemon juice and mix to combine
  • Add flour mixture into the mixing bowl and beat at medium for 1 minute
  • Stir in bananas
  • Pour into 2 pans and bake for about 40 minutes or until tester is clean
      • Be careful not to overbake, gluten-free can become quite dry (I suggest checking your cake about 5-10 minutes prior to the end time to gauge the baking process)
    • If adjusting for more pans see below:
      • If using 4 pans, adjust bake time as follows:
        • 4 pans, 1 pan per oven, begin checking at about 20 min for doneness.
        • 3 pans, 1 pan per oven, begin checking at about 25 min for doneness
  • Cool for 5 mins in pan then invert on rack to complete cooling process
  • Frost when completely cooled (see below for low-FODMAP Peanut Butter Buttercream recipe)
    • Hint: if you do find your cake gets a little overbaked, use my low-FODMAP Simple Syrup in the layers for added moisture and flavor.  It’s a great baker’s secret!
  • I did Peanut Butter Buttercream with chopped peanuts sprinkled between the layers and low-FODMAP Chocolate Buttercream over the cake, but you can opt for your favorite combination

Low-FODMAP Peanut Butter Buttercream Frosting

Serves enough for a 2 layer cake (if you plan to use more than one frosting for this cake then half recipe)

Prep time: 10 min

Ingredients

  • 1 cup low-FODMAP Vegan Spread, such as Earth Balance
    • Can also use butter for non-vegan version
  • 1 heaped cup natural peanut butter (I prefer salted, if you use unsalted then add a pinch salt to the frosting)
  • 4 cups confectioner’s or powdered sugar
  • 2 tsp vanilla extract
  • 1-2 tablespoons low-FODMAP milk (such as almond milk, canned coconut milk or lactose-free milk for non-vegan)
  • Optional:
    • 1/2 cup chopped peanuts for layering/sprinkling over the frosting (for a crunchy texture)
    • 1/2-1 cup low-FODMAP, gluten-free rice crisp cereal for mixing with the frosting (I like gluten-free rice krispies)

Directions

  • Beat the low-FODMAP vegan spread and peanut butter together until fully combined in bowl of electric mixer
  • Add the sugar slowly, then vanilla
  • As needed add low-FODMAP milk or cream until desired consistency is reached
    • For spreading the frosting, you will need a little looser than if piping frosting
  • For added texture, fold in rice crisps, or when decorating cake, sprinkle with chopped peanuts
