Banana Cupcakes with Vanilla Pastry Cream — Do This Next

Step 1: Prepare Your Oven and Pan
Preheat your oven to 350°F (175°C). Line a cupcake pan with paper liners to prevent sticking and ensure easy removal.
Step 2: Mix Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. Set aside.
Step 3: Cream Butter and Shortening
In a large mixing bowl, cream together the unsalted butter and vegetable shortening until light and fluffy, about 3-4 minutes.
Step 4: Add Sugar and Eggs
Gradually add the granulated sugar to the butter mixture, beating well after each addition. Add the eggs one at a time, mixing until fully incorporated. Stir in the vanilla extract.
Step 5: Incorporate Bananas and Buttermilk
Gently fold in the mashed bananas and buttermilk until well combined.
Step 6: Combine Wet and Dry Ingredients
Gradually add the dry ingredients to the wet mixture, mixing until just combined. Be careful not to overmix, as this can lead to dense cupcakes.
Step 7: Fill the Cupcake Liners
Using a scoop or spoon, fill each cupcake liner about two-thirds full with the batter. This will allow room for the cupcakes to rise beautifully in the oven.
Step 8: Bake
Bake in the preheated oven for 18-20 minutes or until a toothpick inserted into the center comes out clean. Let them cool in the pan for 5 minutes before transferring to a wire rack to cool completely.
Step 9: Prepare the Vanilla Pastry Cream
In a medium saucepan, heat the half-and-half over medium heat until it begins to simmer. In a separate bowl, whisk together the egg yolks, sugar, cornstarch, salt, and vanilla extract until smooth. Slowly pour in the hot half-and-half, whisking constantly to temper the eggs.
Step 10: Cook the Pastry Cream
Return the mixture to the saucepan and cook over medium heat, whisking constantly, until thickened and bubbly. Remove from heat and let cool to room temperature, then refrigerate until ready to use.
Step 11: Frost the Cupcakes
Once the cupcakes are completely cool, use a piping bag or a spoon to generously top each cupcake with the vanilla pastry cream. Feel free to get creative with your frosting technique!
Fresh Takes Through the Year

- For a tropical twist, add shredded coconut to the batter or top the cupcakes with toasted coconut flakes.
- Incorporate spices like cinnamon or nutmeg for a warm flavor profile during the fall.
- Mix in chocolate chips or nuts for added texture and flavor.
- For a fun summer treat, consider topping these cupcakes with fresh fruit like strawberries or blueberries.
Easy-to-Miss Gotchas
- Ensure your bananas are very ripe for optimal sweetness and flavor.
- Don’t overmix the batter; this can lead to tough cupcakes.
- Let the cupcakes cool completely before frosting to prevent the pastry cream from melting.
- When making the pastry cream, be patient while it thickens; it may take a little time but will be worth it!
Cooling, Storing & Rewarming
Once baked, let your Banana Cupcakes with Vanilla Pastry Cream cool on a wire rack. If not serving immediately, store them in an airtight container in the refrigerator for up to three days. To enjoy them warm, simply pop them in the microwave for a few seconds, but be cautious not to overheat them as the pastry cream may become runny.

Can I make the pastry cream in advance?
