Cooking Instructions

Follow these simple steps to prepare this delicious Peanut Butter & Jelly Cookie Bars:

Step 1: Preheat Your Oven

Preheat oven to 350°F (175°C). Grab an 8×8 inch baking dish and line it with parchment paper for easy removal later.

Step 2: Combine Dry Ingredients

In a bowl, whisk together flour, baking powder, and salt. Set this aside while you work on the wet ingredients.

Step 3: Cream the Butter and Sugars

In another bowl, beat softened unsalted butter, granulated sugar, and brown sugar until light and fluffy—around three minutes should do it.

Step 4: Mix in Peanut Butter and Eggs

Add in the creamy peanut butter and mix until well combined. Then crack in those lovely room-temperature eggs one at a time, mixing until smooth.

Step 5: Fold in Dry Mixture

Gradually incorporate the dry mixture into the wet ingredients. Mix just until combined—don’t overdo it!

Step 6: Assemble Your Cookie Bars

Spread half of the dough evenly into your prepared baking dish. Layer on your favorite jelly or jam before crumbling the remaining dough on top like it’s an edible snowstorm.

Step 7: Bake to Perfection

Bake for about 25-30 minutes or until golden brown. Let them cool before slicing them into squares like a pro chef!

Transfer to plates and serve these delightful bars warm with a glass of milk for an experience that will take you straight back to those carefree days of childhood!

Now you’ve got a fantastic treat that satisfies sweet cravings while bringing back fond memories!
