Peanut Butter and Jam Bars

Really really good. Adapted slightly from Our Best Bites.

Bars:
1/2 cup sugar
1/2 cup brown sugar
1/2 cup butter, softened
1/2 cup creamy peanut butter
1 large egg
1 teaspoon vanilla
1 1/4 cups flour
3/4 teaspoons baking soda
1/2 teaspoon baking powder
1 cup strawberry jam (or your favorite flavor)

Glaze:
1/4 cup butter, melted
2 cups powdered sugar
1 teaspoon vanilla
2 Tablespoons hot water (no more than 2T!)

Preheat oven to 350F.

Cream butter and sugars together until light and fluffy. Add peanut butter and mix just until combined. Add egg and vanilla and mix again. Measure out the 1 1/4 cups flour in a separate bowl. Add small amounts to the peanut butter mixture while mixer is running (about 1/4 cup at a time). When about half of the flour is left, add the baking soda and powder to it. Combine it well, then add to the peanut butter dough and mix until all is incorporated.

Reserve one full cup for the topping. Take remaining dough and press into the bottom of an ungreased 9x13 pan. (Tip: crumble it all across the bottom and then press down with your fingers.)

Bake for 12-15 minutes or until slightly set.

Remove from oven and let cool for 10 minutes. Spread jam over the top evenly.

Take the reserved dough and cover jam layer. (Tip: it's easier to flatten little pieces of dough at a time with your fingers, then place on top of jam. Some of the jam will show through when you're finished, but that's fine.)

Bake at 350F for 14-15 minutes. The top should be set and just barely golden brown. Remove from oven and cool on rack in pan.

When cool, mix up the glaze with wire whisk. Pour over top and spread evenly. Let glaze set for a bit to harden a little, then cut into squares.
