Peanut Butter Chocolate Chip Valentine’s Blondies – Fast, EASY blondies loaded with peanut butter, chocolate chips, and topped with peanut butter HEARTS!! Bring them to a Valentine’s Day party or surprise someone special!!
If you need an easy dessert to bring to a Valentine’s party or want to surprise someone special with a Valentine’s Day treat, this is the perfect recipe.
The blondies are fast, easy, made in one bowl, and you don’t even need a mixer.
I used my favorite blondie base recipe and with 40+ versions and counting, it never lets me down.
These soft, buttery blondies are studded with chocolate chips and have fabulous peanut butter flavor in both dough and on top thanks to these Reese’s peanut butter hearts.
There are lots of heart-shaped chocolates for sale this time of year but what I like about the ones I used is that they’re slightly larger than most other hearts and they nicely fill up the blondie rather than looking small or skimpy. If you can’t find them in your local store, use whatever is convenient.
However one caveat is that I had to use a paring knife to open up the tops of the hearts a little more. Straight out the package they look more like ovals than hearts and I like hearts that have a deeper V at the top. It took 2 minutes to make two small cuts in each heart to get a deeper V, no biggie.
I used mini chocolate chips because I prefer how they disperse more evenly throughout. Also the smaller chips really provide a true chocolate-in-every-bite experience but regular chips are fine.
These blondies are going to be the hit of your Valentine’s chocolate feasting. After all, isn’t that what Valentine’s Day is all about – feasting on chocolate (and peanut butter).
Pin This Recipe
- 1/2 cup unsalted butter (1 stick), melted
- 1 large egg
- 1 cup light brown sugar, packed
- 1/2 cup creamy peanut butter
- 1 tablespoon vanilla extract
- 1 scant cup all-purpose flour
- 1/2 teaspoon salt, or to taste
- 1/2 cup mini semi-sweet chocolate chips (or 3/4 cup regular sized chocolate chips)
- 9 Reese's Valentine's Day Peanut Butter Hearts
- Preheat oven to 350F. Line an 8-by-8-inch baking pan with aluminum foil, spray with cooking spray; set aside.
- To a large, microwave-safe bowl add the butter and heat to melt, about 1 minute on high power.
- Wait momentarily before adding the egg so you don’t scramble it. Add the egg, brown sugar, peanut butter, vanilla, and whisk until smooth.
- Add the flour, salt, and stir until just combined, don’t overmix.
- Add the chocolate chips and stir to combine.
- Turn batter out into prepared pan, smoothing the top lightly with a spatula. Bake for about 20 minutes, or until top is set in center and done. A toothpick inserted in the center should come out clean, or with a few moist crumbs, but no batter. Blondies firm up as they cool.
- After blondies are out of the oven, add the Reese's hearts, evenly spaced in rows and columns, 3-by-3. Lightly press them down so they adhere. The chocolate will start melting and to avoid it from melting too much because you want the heart shape to stay intact, place the pan in the fridge for about 10 minutes and then return pan to counter to cool completely before slicing and serving. Blondies will keep airtight at room temp for up to 1 week.
