Next, in a separate bowl, whisk together the remaining 1/2 cup of sugar, flour, baking powder, and salt. In another mixing bowl, beat the softened butter and brown sugar together until light and fluffy—this step always makes my kitchen smell delightful! Add in the eggs, one at a time, mixing well after each addition, and then stir in the vanilla. Gradually incorporate the dry ingredients, alternating with the milk until you have a smooth batter.
Pour the batter gently over the fruit mixture in the cake pan, making sure to cover the fruit completely. It’s okay if some of the fruit peaks through—trust me, it will sink during baking and create a beautiful topping! Bake in your preheated oven for about 45-50 minutes or until the cake is golden brown and a toothpick inserted into the center comes out clean. When I see that golden color, I get really excited!
Once it’s done baking, let the cake cool in the pan for about 10 minutes before inverting it onto a serving plate. This part is always the most satisfying. As you remove the pan, the caramelized fruit will glisten and beautify your creation. Let it cool a little longer before cutting, but I can never resist a small slice while it’s still warm!
Pro Tips for Best Results
I experimented with different ratios of strawberries to rhubarb, and I found that a 1:1 ratio gives you a perfect balance of sweetness and tartness. If you prefer a more pronounced tartness, feel free to increase the rhubarb slightly. I also like to sprinkle a bit of cinnamon into the batter for an extra layer of flavor—it complements the fruit so beautifully!
When it comes to greasing your cake pan, I recommend using butter and a light dusting of flour. This ensures that your cake will release easily without sticking, which is crucial for that beautiful upside-down presentation. After a few trials, I learned that using a non-stick spray can sometimes lead to a less-than-perfect release.
Lastly, timing is key! Make sure to check your cake a few minutes before the suggested baking time. Ovens can vary, and you want to avoid overbaking to ensure that your cake remains moist and tender.
Common Mistakes to Avoid
One common mistake I made when first trying this cake was not properly preparing the fruit. If the strawberries and rhubarb are too watery, it can lead to a soggy bottom. Make sure to drain any excess liquid after letting the fruits sit with sugar; it makes a significant difference! (See the next page below to continue…)
