The classic combo of strawberries and bananas shine in this upside down cake. It's a dense banana cake layer, like a banana bread bar, covered with a jammy layer of fresh strawberries. Yum!

Ingredients for this cake
Gluten Free Flour - I use Bob's Red Mill 1-to-1 Flour Blend for most of my recipes. I think it works great for cakes. You can use the flour blend of your choice, but make sure it contains xanthan gum.
Baking Soda & Baking Powder - to help the cake rise.
Vanilla, Cinnamon & Salt - extra layers of flavor.
Oil - You can use any light flavored cooking oil. I use either melted coconut oil or olive oil, as shown in the photo above.
Sugar & Light Brown Sugar - the combination of sugars compliment the flavor of the fruit while keeping the cake moist.
Egg & Egg Yolk - These provide the structure for the cake. I have not tried the recipe with egg replacers, but adding a third banana in place of the egg would be a good option.
Bananas - The recipe calls for ⅔ cup of mashed banana. You want to use overripe bananas for the most flavor. You should need about 2 medium sized bananas for this recipe.
For the topping:
Strawberries - You will need approximately 1 full pound of strawberries, destemmed and sliced. Here they are shown sliced into ¼" thick coins, but you can slice them thicker if you desire. You can also substitute other fresh fruit in this recipe - blueberries would be amazing!
Light Brown Sugar & Starch - creates the jammy layer when baked, by combining with the strawberry juice that is released.
How to make a strawberry upside down cake
Begin by preparing your fruit.
- Step 1 - Place sliced berries, brown sugar and starch into a medium sized bowl.
- Step 2 - Stir until the berries are well coated with the sugar.
- Step 3 - Allow the berries to sit while you prepare the cake batter. The sugar will draw some of the moisture from the berries which will help prevent a soggy cake.
Next, prepare your cake batter.
- Step 1 - Combine the flour, sugar, baking soda, baking powder, cinnamon and salt in a large bowl. Whisk together until well combined.
- Step 2 - In a second bowl, crack your eggs. Whisk until frothy, like soap bubbles.
- Step 3 - Add the vanilla and oil to the eggs and whisk until smooth.
- Step 4 - Add the egg mixture and the mashed banana to the dry ingredients. Fold together about 15 strokes until all flour is incorporated.
- Step 5 - Place the sugar coated strawberries in the bottom of your lined pan. Discard the liquid in the bowl.
- Step 6 - Spoon the cake batter onto the strawberries to avoid disturbing the pattern.
- Step 7 - Spread the batter into an even layer with an offset spatula.
- Step 8 - Bake!
How to Store Upside Down Cake
This cake is best served the day it is baked. But if you do have leftovers, store them in the refrigerator in an airtight container. The cake will stay good for 3-4 days.
To serve, reheat an individual slice in the microwave for 10-15 seconds. And we love ours topped with a dollop of coconut whipped cream.
