Peanut Butter Banana Sandwiches Cake


This is another recipe inspired by a great one from the Food Network. Their original is from the Retro Desserts cookbook. Peanut butter and bananas is one of my favourite combinations, so I’ve had this recipe on my list for some time now. The cake is baked as a loaf cake, then sliced as if it were a loaf of bread and made into a sandwich with bananas and peanut butter buttercream. Hot fudge sauce and ice cream, if desired, are put on top, making the dish into a sort of hot fudge sundae.

This was my first time using Montina Flour. It is similar to wild rice flour in taste and texture only coarser. When I looked at it and smelt it it reminded me of bits of grass seed and I knew those flecks would appear in the batter after it was baked. Mixing it into a banana cake, since bananas have those flecks too, seemed the perfect way to work with the natural graininess. If you can’t get Montina flour or wild rice flour, then brown rice flour, teff flour, or buckwheat flour would be good as well.

Overall this cake was wonderfully decadent. I liked it with or without ice cream. The banana cake is not as dense as I am accustomed to banana cakes being, which was nice. The only problem I had was not being patient enough with it to let it bake as long as it needed to set all the way through. It needs a long time to bake and I was getting tired of poking it every five minutes to see if the last bit of wetness had congealed, so I pulled it early. I paid for my impatience with the cake falling in the centre just a bit. Since it gets sliced up to serve anyhow, I wasn’t too bothered. Those slices from the centre were shorter in stature and gummier on the top than the others but still tasted delicious.

The nice thing about the versatility of slices is you can use even half of one slice as the top and bottom of the sandwich if you feel like eating less. I suppose you could slice the whole cake in half for one big sandwich if you felt like it :D .

Peanut Butter Banana Sandwiches Cake

280g (2 1/2 cups) gluten-free flour blend (I used montina flour, tapioca flour, and arrowroot starch)

1 teaspoon bicarbonate of soda

1/4 teaspoon baking powder

170g (3/4 cup) butter

280g (1 1/4 cups) caster sugar

3 eggs

3 ripe bananas

100 ml (1/2 cup) sour cream

1 tablespoon vanilla extract

Preheat to 175C (350F). Grease or spray a 21 x 11 cm (8 x 4 inches) loaf tin. Line the bottom with a rectangle of parchment paper. Sift the gluten-free flour blend, bicarbonate of soda, baking powder, and salt together into a bowl. Repeat two times for extra airiness. (You could probably just sift once and have the cake be ok, but if you really want to sift in those extra air molecules, then sift away :) .)

In a separate mixing bowl, beat the butter and sugar together until well combined. Add the eggs, 1 at a time, beating until each is incorporated. Continue beating until light and fluffy.

In a bowl, mash the bananas until smooth and not lumpy. Stir the sour cream and vanilla into the bananas. Beat 1/3rd of the flour mixture into the creamed butter and sugar. Next, beat in half of the banana mixture, then another 1/3rd of the flour. Beat in the other half of the banana mixture and the last 1/3rd of the flour.

Pour the batter into the prepared tin and bake for 60 minutes or until a skewer inserted comes out clean. (I recommend going with the skewer test over the time, since this cake is a bit wetter than most. Start checking it after 45 minutes baked, then every five minutes or so until done.) Let the cake cool completely in the tin on a rack.


4 bananas

Peanut Butter Buttercream (recipe below)

Chocolate fudge sauce (recipe below)

Ice Cream (optional)

Peanut Butter Buttercream

115g (1/2 cup) butter

225g (1 cup) creamy peanut butter

85g (3/4 cup) icing sugar

Beat the peanut butter and butter together with an electric mixer until smooth. Add the icing sugar and beat on high until icing is fluffy and light.

Chocolate Fudge Sauce

60 ml (1/4 cup) very hot brewed coffee (I used instant)

55g (1/4 cup) caster sugar

60g (1/2 cup) unsweetened cocoa powder

60 ml (1/4 cup, 4 tablespoons) golden syrup

60g (2 oz) semisweet chocolate, chopped

15g (1 tablespoon) butter

Prepare the coffee, then combine it with the sugar and cocoa powder in a medium bowl. Add the golden syrup and stir together until texture is smooth and even. Place the chocolate and butter in a bowl set on top of a pot of simmering water. After the chocolate is completely melted, stir in the syrup-cocoa mixture until smooth. Remove from heat and set aside. Store in a sealed container in the fridge or the freezer.


Turn the cooled cake out of the tin onto a plate or cutting board. With a serrated knife, cut the loaf into slices. (For a smaller serving, slice each of those slices in half again.) Peel the bananas and cut them into thin rounds. To assemble, spread half the cake slices with peanut butter buttercream and layer with banana slices. Top with remaining cake slices to form sandwiches. Put a scoop of ice cream on each sandwich and pour the chocolate fudge sauce over it. Enjoy!

    Oh! One of my favorite things is seeing people’s Corelle in their food photos. That’s my sister’s set – I think she got married in ‘89? How about you? :)

    I got married in ‘99, so mine is green ivy! It’s in one of these pics:

    Happy gluten free cooking!

    Hello Tenille,
    Hehe, that’s neat! I never thought of following people’s history through their Corelle before. I got married in 2001. The Corelle was given to my husband by his parents when he moved out of their house as a bachelor. He guesses it is about 20 years old, which would make ‘89 correct. Thank you for the comment :) .
