It’s time again for a few friends and me to get together and bake up a peanut butter themed recipe. This month, because Autumn is knocking on the door. We have decided to use a Fall favourite ingredient, apples! I have been meaning to make an upside-down cake for ages and I thought this would be the perfect excuse to try something a little different. That is how this Peanut Butter Upside Down Apple Cake came into being, and if you love apples and you love peanut butter then this cake is definitely for you. 🍏🍎😍❤️😋
I’ve been wanting to make an upside down cake for ages, any long term reader of my blog will know that I am a fruit fanatic. I have been since I was a child, and I will always try and find a way to add fruit to my recipes. As much as I love the traditional pineapple and cherry upside-down cake, I really wanted to share something different with you guys. And with the monthly peanut butter bash coming up and apples being the ingredient of the month I thought this would be a perfect pairing.
I used a sweet crisp small dessert apple for this peanut butter upside down apple cake, but you could always use something a little sharper if you prefer.
To give this cake the peanut butter element I needed for the challenge, I lightly flavoured the sponge with peanut butter. I also added a swirl of peanut butter into the batter before baking. Both of these small additions gave this cake a gentle peanut butter flavour which intensified slightly when the cake was left overnight. Which is a bonus for a peanut butter lover like me.
Have you ever baked with crème fraîche before? If not you should really give it a try. It really makes a cake wonderfully tender, moist and light. It has very similar properties to buttermilk and yoghurt in a bake. If you are struggling to find crème fraîche then you can substitute it for the aforementioned buttermilk or yoghurt.
Finally, if you can use crème fraîche then do, you won’t regret it I promise. It really does help to turn this Peanut Butter Upside Down Apple Cake into something special.
Peanut Butter Upside Down Apple Cake
- 4 small dessert apples
- 2 tablespoons dark brown sugar
- 1/2 teaspoon ground cinnamon
- 150 grams plain / all purpose flour (1 and 1/4 cups)
- 1/2 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
- 155 grams unsalted butter (3/4 cup)
- 135 grams smooth peanut butter - divided (1/2 cup)
- 105 grams granulated sugar (1/2 cup)
- 90 grams dark brown sugar (1/2 cup - lightly packed)
- 2 large eggs
- 2 teaspoons vanilla
- 170 grams creme fraiche (2/3 cup)
- Preheat your oven to 180C / 350F / Gas mark 4 and lightly grease a 9 inch cake pan and place a disk of parchment paper on the bottom and lightly butter the parchment paper.
- Slice your apples thinly and then cut your slices in half. To stop them from browning place the slices in a bowl of cold very lightly salted water.
- In a small bowl mix the dark brown sugar and cinnamon together, then sprinkle it all over the buttered parchment. Then place the apple slices in concentric circles over the sugar cinnamon mix. You should have enough slices for 2 thin layers. Place your cake tin to one side.
- In a medium sized mixing bowl mix the flour, baking soda, baking powder and salt together, then place to one side.
- In a stand mixer or in a large mixing bowl using an electric hand mixer cream together the butter and sugars until light and fluffy.
- Add in half of the peanut butter and mix until everything is well combined, scraping down the sides of the bowl as needed.
- Beat in the eggs one at a time, then mix in the vanilla.
- On a slow speed gently beat in half of the flour mixture.
- Then add the creme fraiche and gently mix it in then add the remaining flour mixture and mix until everything is combined.
- Pour the batter over the apple slices and smooth it out with a spatula.
- Lightly warm the remaining peanut butter in the microwave for 30-45 seconds. You want it to be runny not super hot. Spoon or drizzle be peanut butter over the cake batter and swirl it in with a clean knife.
- Pop your cake into your hot oven and bake for 45 minutes. Some ovens (like mine) are slower and your cake may require a little more time. To stop your cake from over browning place some foil over the top of the cake and bake for a further 5-10 minutes.
- After 45 minutes check your cake for doneness if a pick comes out clean your cake is baked of not follow the above step.
- Leave your cake to cool for 15-20 minutes in the tin before turning it out onto a wire rack and gently remove the parchment paper then leave your cake to fully cool down to room temperature before storing it in an airtight tin.
- Kept at room temperature this cake will be good for 5-7 days. This Cake will also freeze well for 3 months.
- I used dark brown sugar in this recipe but you can easily substitute it with light brown sugar if that is what you have in your pantry.
- Creme fraiche can be substituted for buttermilk or plain yoghurt.
