🛒 Ingredients for Funfetti Cake Squares | What You’ll Need

1 ½ cups all-purpose flour
1 tsp baking powder
¼ tsp baking soda
¼ tsp salt
½ cup unsalted butter, softened
¾ cup granulated sugar
2 large eggs
1 tsp vanilla extract
½ cup sour cream or plain yogurt
½ cup milk
½ cup rainbow sprinkles (jimmies style preferred)

🥣 How to Make Funfetti Cake Squares Step-by-Step

Step 1: Preheat and prep

Preheat your oven to 175°C (350°F). Line an 8×8 or 9×9 baking pan with parchment paper or grease well.

Step 2: Mix dry ingredients

In a bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.

Step 3: Cream butter & sugar

In a large bowl, beat the butter and sugar together until light and fluffy. Add eggs and vanilla, mix well.

Step 4: Add sour cream and milk

Mix in sour cream (or yogurt), followed by milk. The batter may look a little lumpy—totally normal!

Step 5: Combine and add sprinkles

Add the dry ingredients to the wet and mix until just combined. Gently fold in the rainbow sprinkles — don’t overmix or colors may bleed.

Step 6: Bake

Pour batter into the prepared pan and spread evenly. Bake for 25–30 minutes or until a toothpick inserted comes out clean.

Step 7: Cool & cut

Let cool completely, then slice into squares. Serve as-is, or dust lightly with powdered sugar if you like!
